This overhead + comes from trunk key computation, wire matching, state map operations, and + promise management. +- AOT-compiled code eliminates this entirely. The generated function is a + straight-line sequence of `await` calls and property accesses — the only + latency is the actual tool execution time. +- For bridges with many tools (5+), the savings compound because the runtime + does O(wires × tools) work for scheduling, while AOT does O(tools) with + pre-computed dependency order. + +**Throughput improvement:** +- Fewer allocations: no state maps, no trunk key strings, no wire arrays. +- Better V8 optimization: the generated function has a stable shape that V8 + can inline and optimize. The runtime's polymorphic dispatch (multiple wire + types, MaybePromise branches) defeats V8's inline caches. +- Reduced GC pressure: no per-request shadow trees or intermediate objects. + +**Estimated improvement: 2–5× for simple bridges, 5–10× for complex ones** +(based on framework overhead ratio to total request time). + +### Where AOT does NOT help + +- **Network-bound workloads:** If tools spend 50ms+ making HTTP calls, the + 0.5ms framework overhead is noise. AOT helps most when tool execution is + fast (in-memory transforms, math, data reshaping). +- **Dynamic routing:** Bridges that use `define` blocks, pipe operators, or + runtime tool selection can't be fully ahead-of-time compiled. +- **Tracing/observability:** The runtime's built-in tracing adds overhead but + provides essential debugging information. AOT would need to re-implement + this as optional instrumentation. + +--- + +## Feasibility Assessment + +### Is this realistic to support alongside the current executor? + +**Yes, with caveats.** The AOT compiler can coexist with the runtime executor +as an optional optimization path. Here's the analysis: + +#### Advantages + +1. **Complementary, not competing.** AOT handles the "hot path" (production + requests) while the runtime handles the "dev path" (debugging, tracing, + dynamic features). Users opt in per-bridge. + +2. **Minimal maintenance burden.** The codegen is ~500 lines and operates on + the same AST. When new wire types are added, both the runtime and AOT need + updates, but the AOT changes are simpler (emit code vs. evaluate code). + +3. **Clear subset.** Not every feature needs AOT support. ToolDefs with + inheritance, define blocks, and pipe operators can fall back to the runtime. + The AOT compiler can throw a clear error: "This bridge uses features not + supported by AOT compilation." + +4. **Easy integration.** The generated function has the same interface as + `executeBridge` — `(input, tools, context) → Promise`. It can be a + drop-in replacement in the GraphQL resolver layer. + +#### Challenges + +1. **Feature parity gap.** The runtime supports features that are hard to + compile statically: overdefinition (multiple wires targeting the same path + with null-boundary semantics), error recovery chains, and dynamic tool + resolution. Supporting these would roughly double the codegen complexity. + +2. **Testing surface.** Every codegen path needs correctness tests that mirror + the runtime's behavior. This is a significant ongoing investment — any + semantic change in the runtime needs a corresponding codegen update. + +3. **Error reporting.** The runtime provides rich error context (which wire + failed, which tool threw, stack traces through the execution tree). AOT + errors are raw JavaScript errors with less context. + +4. **Versioning.** If the AST format changes, the AOT compiler must be + updated in lockstep. This couples the compiler and runtime release cycles. + +#### Recommendation + +**Ship as experimental (`@stackables/bridge-aot`) with a clear feature +subset.** Target bridges that: + +- Use only pull wires, constants, and simple fallbacks +- Don't use ToolDefs with inheritance or `define` blocks +- Are on the hot path and benefit from reduced latency + +Add a `compileBridge()` check that validates the bridge uses only supported +features, and throw a descriptive error otherwise. This lets users +incrementally adopt AOT for their performance-critical bridges while keeping +the full runtime for everything else. + +--- + +## Example: Generated Code + +Given this bridge: + +```bridge +bridge Query.catalog { + with api as src + with output as o + + o.title <- src.name + o.entries <- src.items[] as item { + .id <- item.item_id + .label <- item.item_name + } +} +``` + +The AOT compiler generates: + +```javascript +export default async function Query_catalog(input, tools, context) { + const _t1 = await tools["api"]({}); + return { + "title": _t1?.["name"], + "entries": (_t1?.["items"] ?? []).map((_el) => ({ + "id": _el?.["item_id"], + "label": _el?.["item_name"], + })), + }; +} +``` + +This is a zero-overhead function — the only cost is the tool call itself. + +--- + +## Next Steps + +If the team decides to proceed: + +1. **Add `catch` fallback support** — wrap tool calls in try/catch, emit + fallback expressions. +2. **Add `force` statement support** — emit `Promise.all` for side-effect + tools. +3. **Add ToolDef support** — merge tool definition wires with bridge wires at + compile time. +4. **Benchmark suite** — use tinybench (already in the repo) to compare + runtime vs. AOT on representative bridges. +5. **Integration with `executeBridge`** — add an `aot: true` option that + automatically compiles and caches the generated function. +6. **Source maps** — generate source maps pointing back to the `.bridge` file + for debugging. diff --git a/packages/bridge-aot/test/codegen.test.ts b/packages/bridge-aot/test/codegen.test.ts index f8c1f587..fee45baa 100644 --- a/packages/bridge-aot/test/codegen.test.ts +++ b/packages/bridge-aot/test/codegen.test.ts @@ -1,6 +1,7 @@ import assert from "node:assert/strict";

charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the next steps from the AOT assessment: Phase 6: catch fallback support - Tool calls that source catch-guarded wires are wrapped in try/catch - Error flag tracks whether tool threw, fallback expression applied Phase 7: force statement support - Critical forces: awaited normally, errors propagate - Fire-and-forget forces (catch null): wrapped in try/catch, errors suppressed - Force-only tools (no output wires) properly scheduled Phase 8: ToolDef support - Resolves ToolDef extends chains (root → leaf merge) - Merges ToolDef constant and pull wires with bridge wires - Bridge wires override ToolDef wires by target key - onError wire generates try/catch with JSON fallback - Context dependencies resolved from tool deps Phase 9: executeAot integration - New executeAot() function with compile-once, run-many caching - WeakMap cache keyed on document object for GC-friendly lifecycle - Matches executeBridge() result format for drop-in replacement 34 tests, all passing.

External Attack Surface (Client ➡️ Bridge Server) + +These are threats initiated by end-users interacting with the compiled GraphQL or REST endpoints. + +### A. SSRF (Server-Side Request Forgery) + +- **The Threat:** An external client manipulates input variables to force the Bridge server to make HTTP requests to internal, non-public IP addresses (e.g., AWS metadata endpoint `169.254.169.254` or internal admin panels). +- **Attack Vector:** A `.bridge` file wires user input directly into a tool's URL: `tool callApi { .baseUrl <- input.targetUrl }`. The `httpCall` implementation constructs URLs via plain string concatenation (`new URL(baseUrl + path)`), permitting path traversal (e.g., `path = "/../admin"`) with no allowlist or blocklist for private IP ranges. +- **Mitigation (Framework Level):** The `std.httpCall` tool should strictly validate or sanitize `baseUrl` inputs if they are dynamically wired. Developers should never wire raw client input to URL paths. All headers from the `headers` input are forwarded verbatim to the upstream — if user-controlled input is wired to `headers`, arbitrary HTTP headers can be injected. +- **Mitigation (Infrastructure Level):** Run the Bridge container in an isolated network segment (egress filtering) that blocks access to internal metadata IP addresses. + +### B. Cross-Tenant Cache Leakage (Information Disclosure) + +- **The Threat:** User A receives User B's private data due to aggressive caching. +- **Attack Vector:** The built-in `createHttpCall` caches upstream responses. The cache key is constructed as `method + " " + url + body` (**headers are not included in the cache key**). If two users with different `Authorization` headers make the same GET request, User B will receive User A's cached response. +- **Current Status:** The cache key does **not** incorporate `Authorization` or tenant-specific headers. Caching is only safe for public/unauthenticated endpoints. To disable caching, set `cache = "0"` on the tool. +- **Recommendation:** Include sorted security-relevant headers (at minimum `Authorization`) in the cache key, or clearly document that caching must be disabled for authenticated endpoints. + +### C. GraphQL Query Depth / Resource Exhaustion (DoS) + +- **The Threat:** A client sends a heavily nested GraphQL query, forcing the engine to allocate massive arrays and deeply resolve thousands of tools. +- **Attack Vector:** `query { users { friends { friends { friends { id } } } } }` +- **Mitigation:** The `@stackables/bridge-graphql` adapter relies on the underlying GraphQL server (Yoga/Apollo). Adopters **must** configure Query Depth Limiting and Query Complexity rules at the GraphQL adapter layer before requests ever reach the Bridge engine. The engine itself enforces `MAX_EXECUTION_DEPTH = 30` for shadow-tree nesting as a secondary guard. + +### D. Error Information Leakage + +- **The Threat:** Internal system details (stack traces, connection strings, file paths) leak to external clients via GraphQL error responses. +- **Attack Vector:** Tools that throw errors containing internal details propagate through the engine and appear in the `errors[]` array of the GraphQL response. When tracing is set to `"full"` mode, complete tool inputs and outputs are exposed via the `extensions.traces` response field — including potentially sensitive upstream data. +- **Mitigation:** Adopters should configure error masking in their GraphQL server (e.g., Yoga's `maskedErrors`). Tracing should never be set to `"full"` in production environments exposed to untrusted clients. + +--- + +## 4. Internal Attack Surface (Schema ➡️ Execution Engine) + +These are threats derived from the `.bridge` files themselves. Even if written by trusted internal developers, malicious or malformed schemas can exploit the Node.js runtime. + +### A. Code Injection via AOT Compiler (RCE) + +- **The Threat:** A malformed `.bridge` file or programmatically constructed AST injects raw JavaScript into the `@stackables/bridge-compiler` code generator. +- **Attack Vector:** The AOT compiler (`bridge-compiler`) generates a JavaScript function body as a string and evaluates it via `new AsyncFunction()`. A developer names a tool or field with malicious string terminators: `field "\"); process.exit(1); //"`. +- **Mitigation (multi-layered):** + 1. **Identifier validation:** The Chevrotain lexer restricts identifiers to `/[a-zA-Z_][\w-]*/` — only alphanumeric characters, underscores, and hyphens. + 2. **Synthetic variable names:** The codegen generates internal variable names (`_t1`, `_d1`, `_a1`) — user-provided identifiers are never used directly as JS variable names. + 3. **JSON.stringify for all dynamic values:** Tool names use `tools[${JSON.stringify(toolName)}]`, property paths use bracket notation with `JSON.stringify`, and object keys use `JSON.stringify(key)`. + 4. **Constant coercion:** `emitCoerced()` produces only primitives or `JSON.stringify`-escaped values — no raw string interpolation. + 5. **Reserved keyword guard:** `assertNotReserved()` blocks `bridge`, `with`, `as`, `from`, `throw`, `panic`, etc. as identifiers. +- **Residual Risk:** If consumers construct `BridgeDocument` objects programmatically (bypassing the parser), they bypass identifier validation. The `JSON.stringify`-based codegen provides defense-in-depth but edge cases in `emitCoerced()` for non-string primitive values should be reviewed. +- **CSP Note:** `new AsyncFunction()` is equivalent to `eval()` from a Content Security Policy perspective. Environments with strict CSP (`script-src 'self'`) will block AOT execution. + +### B. Prototype Pollution via Object Mapping + +- **The Threat:** The Bridge language constructs deep objects based on paths defined in the schema. +- **Attack Vector:** A wire is defined as `o.__proto__.isAdmin <- true` or `o.constructor.prototype.isAdmin <- true`. Both the interpreter (`setNested`) and the compiler (nested object literals) will attempt to construct this path. +- **Mitigation:** The `UNSAFE_KEYS` blocklist (`__proto__`, `constructor`, `prototype`) is enforced at three points: + 1. `setNested()` in `tree-utils.ts` — blocks unsafe assignment keys during tool input assembly. + 2. `applyPath()` in `ExecutionTree.ts` — blocks unsafe property traversal on source refs. + 3. `lookupToolFn()` in `toolLookup.ts` — blocks unsafe keys in dotted tool name resolution. +- **Test Coverage:** `prototype-pollution.test.ts` explicitly validates all three enforcement points. + +### C. Circular Dependency Deadlocks (DoS) + +- **The Threat:** The engine enters an infinite loop trying to resolve tools. +- **Attack Vector:** Tool A depends on Tool B, which depends on Tool A. +- **Mitigation:** + - _Compiler:_ Kahn's Algorithm in `@stackables/bridge-compiler` topological sort mathematically guarantees that circular dependencies throw a compile-time error. + - _Interpreter:_ The `pullSingle` recursive loop maintains a `pullChain` Set. If a tool key is already in the set during traversal, it throws a `BridgePanicError`, preventing stack overflows. + +### D. Resource Exhaustion (DoS) + +- **The Threat:** A bridge file with many independent tool calls or deeply nested structures exhausts server memory or CPU. +- **Attack Vector:** A `.bridge` file declares hundreds of independent tools, or deep array-mapping creates unbounded shadow trees. +- **Mitigation (implemented):** + - `MAX_EXECUTION_DEPTH = 30` — limits shadow-tree nesting depth. + - `toolTimeoutMs = 15_000` — `raceTimeout()` wraps every tool call with a deadline, throwing `BridgeTimeoutError` on expiry. + - `AbortSignal` propagation — external abort signals are checked before tool calls, during wire resolution, and during shadow array creation. `BridgeAbortError` bypasses all error boundaries. + - `constantCache` hard cap — clears at 10,000 entries to prevent unbounded growth. + - `boundedClone()` — truncates arrays (100 items), strings (1,024 chars), and depth (5 levels) in trace data. +- **Gaps:** There is no limit on the total number of tool calls per request, no per-request memory budget, and no rate limiting on tool invocations. A bridge with many independent tools will execute all of them without throttling. + +### E. `onError` and `const` Value Parsing + +- **The Threat:** `JSON.parse()` is called on developer-provided values from the AST in `onError` wire handling and `const` block definitions. +- **Attack Vector:** Programmatically constructed ASTs (bypassing the parser) could supply arbitrarily large or malformed JSON, causing CPU/memory exhaustion during parsing. +- **Mitigation:** In normal usage, these values originate from the parser which validates string literals. The impact is limited to data within the execution context (no code execution). Adopters accepting user-supplied ASTs should validate `onError` and `const` values before passing them to the engine. + +--- + +## 5. Playground Attack Surface + +The browser-based playground (`packages/playground`) has a unique threat profile because it executes untrusted Bridge code client-side and provides a public share API. + +### A. CSRF-like Fetch Abuse via Shared Links + +- **The Threat:** An attacker crafts a playground share that, when opened by a victim, makes authenticated HTTP requests to internal APIs using the victim's browser cookies. +- **Attack Vector:** A crafted `.bridge` file using `httpCall` with a `baseUrl` pointing to a victim's internal service. The playground uses `globalThis.fetch` for HTTP calls — the browser will attach cookies for the target domain. The attacker shares the playground link; the victim opens it, and the bridge auto-executes. +- **Mitigation:** The browser's CORS policy prevents reading responses from cross-origin requests (the attacker cannot exfiltrate data). However, side-effect requests (POST/PUT/DELETE) may still succeed if the target API does not enforce CSRF tokens. Adopters of internal APIs should implement CSRF protection and `SameSite` cookie attributes. + +### B. Share Enumeration (Information Disclosure) + +- **The Threat:** Anyone who knows or guesses a 12-character share ID can read the share data. There is no authentication or access control. +- **Attack Vector:** Share IDs are 12-char alphanumeric strings derived from UUIDs. While brute-force enumeration is impractical (36¹² ≈ 4.7 × 10¹⁸ possibilities), share URLs may be leaked via browser history, referrer headers, or shared chat logs. +- **Mitigation:** Shares expire after 90 days. Share IDs have sufficient entropy to resist brute-force. Adopters should be aware that share URLs are effectively "anyone with the link" access — do not share playground links containing sensitive data (API keys, credentials, internal URLs). + +### C. Share API Abuse (Resource Exhaustion) + +- **The Threat:** An attacker floods the share API to exhaust Cloudflare KV storage. +- **Attack Vector:** Repeated `POST /api/share` requests with 128 KiB payloads. +- **Mitigation:** Payload size is capped at 128 KiB. Shares have 90-day TTL (auto-expiry). Cloudflare KV has built-in storage limits. There is no rate limiting — Cloudflare Workers rate limiting or a WAF rule should be applied in production. + +--- + +## 6. IDE Extension Attack Surface + +The VS Code extension (`packages/bridge-syntax-highlight`) provides syntax highlighting, diagnostics, hover info, and autocomplete for `.bridge` files via LSP. + +- **Transport:** IPC (inter-process communication) between the extension host and language server — no network exposure. +- **Document scope:** Limited to `{ scheme: "file", language: "bridge" }` — only local `.bridge` files. +- **No code execution:** The language server only parses and validates — it never executes bridge files or tools. +- **Risk:** A maliciously crafted `.bridge` file in a workspace could trigger high CPU usage during parsing (Chevrotain's lexer uses simple regexes without backtracking, making ReDoS unlikely). The language server runs with VS Code's privilege level. + +--- + +## 7. Operational & Downstream Risks + +### A. Telemetry Data Leakage + +- **The Threat:** Sensitive downstream data (PII, passwords, API keys) is logged to Datadog/NewRelic via OpenTelemetry spans. +- **Attack Vector:** The `@stackables/bridge-core` engine automatically traces tool inputs and outputs. If an HTTP tool returns a payload containing raw credit card data, the span attributes might log it in plain text. +- **Mitigation (implemented):** `boundedClone()` truncates traced data (arrays to 100 items, strings to 1,024 chars, depth to 5 levels) before storing in trace spans, reducing the blast radius. +- **Mitigation (not yet implemented):** A `redact` hook or `sensitive: true` field flag that prevents specific fields from being serialized into telemetry spans. Adopters should configure OpenTelemetry exporters to filter spans in the meantime. + +### B. Unhandled Microtask Rejections + +- **The Threat:** An upstream API fails synchronously, crashing the Node.js process. +- **Attack Vector:** A custom tool written by an adopter throws a synchronous `new Error()` instead of returning a rejected Promise. +- **Mitigation:** The execution engine wraps all tool invocations in exception handlers, coercing errors into Bridge-managed failure states (`BridgePanicError` and `BridgeAbortError` are treated as fatal via `isFatalError()`; all other errors enter the fallback/catch chain). The server remains available. + +### C. Context Exposure via GraphQL Adapter + +- **The Threat:** Sensitive data in the GraphQL context (auth tokens, database connections, session objects) is exposed to all bridge files. +- **Attack Vector:** When `bridgeTransform()` is used without a `contextMapper`, the full GraphQL context is passed to every bridge execution. Any bridge file can read any context property. +- **Mitigation:** Configure `options.contextMapper` to restrict which context fields are available to bridges. This is especially important in multi-tenant deployments where bridge files may be authored by different teams. + +### D. Tool Dependency Cache Sharing + +- **The Threat:** Mutable state returned by tools is shared across shadow trees within the same request. +- **Attack Vector:** `resolveToolDep()` delegates to the root tree's cache. If a tool returns a mutable object, shadow trees (e.g., array mapping iterations) may observe each other's mutations, causing nondeterministic behavior. +- **Mitigation:** Tool functions should return immutable data or fresh objects. The framework does not currently enforce immutability on tool return values. + +--- + +## 8.

Sync fast paths, pre-computed keys, batched materialization — careful work that compounded to a 10× throughput gain on array-heavy workloads. + +Then we asked: what if we removed the engine entirely? + +Not removed as in "deleted the code." Removed as in "generated JavaScript so direct that the engine isn't needed at runtime." An AOT compiler that takes a `.bridge` file and emits a standalone async function — no `ExecutionTree`, no state maps, no wire resolution, no shadow trees. Just `await tools["api"](input)`, direct variable references, and native `.map()`. + +The result: **another 7–46× on top of the already-optimized runtime.** The median is 9.5×. Math expressions hit 46×. Even the slowest case (nested 20×10 arrays) is still 7.4× faster. + +This is the story of building that compiler, the architectural bets that paid off, and what we learned about the gap between interpreters and generated code. + +## The Insight: Per-Request Overhead is the Enemy + +After the first optimization round, we profiled the runtime in its optimized state and asked: _what is it actually doing per request?_ Not "what is slow?" — "what exists at all?" + +Here's what the `ExecutionTree` does for every request, even after all our optimizations: + +1. **Trunk key computation** — concatenates strings to build `"module:type:field:instance"` keys, then uses them as Map lookup keys. For a bridge with 5 tools and 15 wires, that's ~20 string allocations per request. + +2. **Wire resolution** — for each output field, scans the wire array comparing trunk keys. Our `sameTrunk()` is allocation-free and fast for small N, but it still runs per field, per request. + +3. **State map reads/writes** — every resolved value goes into `Record`, and every downstream reference reads from it. That's hash map get/set for what is fundamentally a local variable assignment. + +4. **Topological ordering** — the pull-based model means dependency order is discovered implicitly through recursive `pullSingle()` calls. Beautiful semantically, but it means the engine is re-discovering the execution plan on every request. + +5. **Shadow tree creation** — for a 1,000-element array, the engine creates 1,000 lightweight clones via `Object.create()`, each with its own state map. + +None of these are bugs. None of them are slow in isolation. But together, they add up to a fixed per-request overhead that scales with bridge complexity — and that overhead is fundamentally architectural. You can't optimize it away with better code. You can only remove it by not having an interpreter. + +## The Compiler Architecture + +The compiler (`@stackables/bridge-compiler`) takes a parsed `BridgeDocument` and an operation name, and generates a standalone async JavaScript function. It's a drop-in replacement: + +```diff +- import { executeBridge } from "@stackables/bridge-core"; ++ import { executeBridge } from "@stackables/bridge-compiler"; +``` + +Same API. Same result shape. The first call compiles the bridge into a `new AsyncFunction(...)` and caches it in a `WeakMap>`. Subsequent calls hit the cache — zero compilation overhead. + +### What the generated code looks like + +A bridge like this: + +```bridge +bridge Query.catalog { + with api as src + with output as o + + o.title <- src.name ?? "Untitled" + o.entries <- src.items[] as item { + .id <- item.item_id + .label <- item.item_name + } +} +``` + +Compiles to: + +```javascript +export default async function Query_catalog(input, tools, context, __opts) { + const _t1 = await tools["api"]({}, context); + return { + title: _t1?.["name"] ?? "Untitled", + entries: (_t1?.["items"] ?? []).map((_el0) => ({ + id: _el0?.["item_id"], + label: _el0?.["item_name"], + })), + }; +} +``` + +That's it. No engine. No state map. No wire resolution. The entire bridge collapses into a few lines of JavaScript that V8 can JIT-compile into efficient machine code. + +## The Six Architectural Bets + +Building the compiler required making decisions about _what_ to generate. Each decision was a bet on where the performance would come from. + +### 1. Topological sort at compile time + +The runtime engine discovers dependency order lazily through recursive `pullSingle()` calls. The compiler pre-sorts tool calls using Kahn's algorithm at compile time — a single topological sort over the dependency graph — and emits tool calls in the resolved order. + +This means the generated code is a flat sequence of `const _t1 = await ...; const _t2 = await ...;` — no recursion, no scheduling, no dependency discovery at runtime. V8 loves straight-line code. + +### 2. Direct variable references instead of state maps + +The runtime stores all resolved values in a `Record` state map, keyed by trunk keys like `"_:Query:simple:1"`. Every read is a hash map lookup. Every write is a hash map insertion. + +The compiler replaces this with local variables: `_t1`, `_t2`, `_t3`. A variable access in optimized JavaScript is a register read — effectively zero cost. No hashing, no collision chains, no string comparison. + +### 3. Native `.map()` instead of shadow trees + +This was the biggest architectural bet. The runtime creates a shadow tree per array element — a lightweight clone via `Object.create()` that inherits the parent's state. For 1,000 elements, that's 1,000 shadow trees, each with its own state map, each resolving element wires independently. + +The compiler replaces this with a single `.map()` call: + +```javascript +(source?.["items"] ?? []).map((_el0) => ({ + id: _el0?.["item_id"], + label: _el0?.["item_name"], +})); +``` + +No object allocation per element. No state map per element. Just a function call that returns an object literal. V8 can inline this, eliminate the closure allocation, and vectorize the field accesses. + +### 4. Inlined internal tools + +The Bridge language has built-in operators for arithmetic (`+`, `-`, `*`, `/`), comparisons (`==`, `>=`, `<`), and string operations. In the runtime, these are implemented as tool functions in an internal tool registry, dispatched through the same `callTool()` path as external tools. + +The compiler inlines them as native JavaScript operators: + +```javascript +// Runtime: goes through tool dispatch, state map, wire resolution +// Compiled: emitted as a direct expression +const _t1 = Number(input?.["price"]) * Number(input?.["qty"]); +``` + +This is where the 46× speedup on math expressions comes from. The runtime pays the full tool-call overhead (build input object, dispatch, extract output) for what is fundamentally `a * b`. + +### 5. Optional chaining instead of try/catch navigation + +The runtime uses try/catch blocks for safe property access deep in the resolution chain. The compiler uses JavaScript's native `?.` optional chaining operator, which V8 compiles to a null check + branch — much cheaper than setting up exception handling frames. + +### 6. `await` per tool, not `isPromise()` per wire + +The [first optimization round](/blog/20260302-optimize/) introduced `MaybePromise` to avoid unnecessary `await` on already-resolved values. This was a big win for the runtime because most values are synchronous between tools. + +The compiler takes a simpler approach: it just uses `await` on every tool call and does nothing special for synchronous intermediate values (which are just variable references). This is actually faster because: + +- Tool calls genuinely return promises (they call external functions) +- Between tools, all access is synchronous variable reads with no `await` at all +- V8's `await` on an already-resolved promise is fast (~200ns), but the compiler doesn't even hit that path for intermediate values + +## The Numbers + +We built a [side-by-side benchmark suite](https://github.com/stackables/bridge/blob/main/packages/bridge/bench/compiler.bench.ts) that runs identical bridge documents through the runtime interpreter and the compiler, measuring throughput after compile-once / parse-once setup: + +| Benchmark | Runtime (ops/sec) | Compiled (ops/sec) | Speedup | +| --------------------------- | ----------------- | ------------------ | --------- | +| passthrough (no tools) | 711K | 6,786K | **9.5×** | +| simple chain (1 tool) | 543K | 5,016K | **9.2×** | +| 3-tool fan-out | 203K | 3,044K | **15.0×** | +| fallback chains (?? / \|\|) | 308K | 3,790K | **12.3×** | +| math expressions | 121K | 5,564K | **45.9×** | +| flat array 10 | 162K | 1,436K | **8.8×** | +| flat array 100 | 25K | 264K | **10.5×** | +| flat array 1,000 | 2.7K | 29.3K | **11.0×** | +| nested array 5×5 | 45K | 365K | **8.1×** | +| nested array 10×10 | 16K | 122K | **7.6×** | +| nested array 20×10 | 8.3K | 61K | **7.4×** | + +**Median speedup: 9.5×.** The range is 7.4× to 45.9×, with the highest gains on workloads dominated by the runtime's per-wire overhead (math expressions, multi-tool fan-outs). + +Note these numbers are _on top of_ the runtime's already 10× optimized state. Compared to the original unoptimized engine from six months ago, the compiled path is roughly 75–100× faster on array workloads. + +### Why math expressions are 46× faster + +The math expression benchmark (`o.total <- i.price * i.qty`) is the extreme case because every piece of the runtime overhead compounds: + +1. The parser produces two pipe handles (internal tools) for the multiplication +2. The runtime resolves input wires → schedules the internal `multiply` tool → builds an input object → calls the tool function → extracts the result from the output → stores in state map +3. For 3 output fields, this happens 3 times + +The compiler emits `Number(input?.["price"]) * Number(input?.["qty"])`. That's a single CPU multiply instruction after V8 JIT compilation. Everything else — the scheduling, the state map, the tool dispatch — simply doesn't exist. + +## Correctness: 186 Tests, 150 Shared + +"Faster" means nothing if it's wrong. The compiler has 186 tests: 36 unit tests for codegen-specific behavior, and **150 shared data-driven parity tests** that run every scenario against both the runtime `executeBridge()` and the compiler's `executeBridge()`, asserting identical results. + +The test suite covers: pull wires, constants, nullish/falsy/catch fallbacks, ternary, array mapping (flat, nested, root), break/continue, `force` statements, ToolDef blocks (with extends chains, onError, context/const dependencies), `define` blocks, `alias` declarations, overdefinition, string interpolation, math/comparison expressions, pipe operators, abort signals, and tool timeouts. + +Every feature the runtime supports, the compiler supports — and both are verified to produce the same output. + +## What the Compiler Doesn't Do + +Trade-offs exist. The compiler intentionally drops: + +- **OpenTelemetry tracing.** The runtime wraps every tool call in OTel spans for observability. The compiler skips this for maximum throughput. In production, you can run the runtime for traced requests and the compiler for the rest. + +- **Runtime overdefinition bypass.** The runtime's `short-circuit` optimization (skip expensive tools when cheaper sources already resolve) happens dynamically. The compiler calls all tools in topological order because it can't predict which values will be null at compile time. + +- **Rich error context.** The runtime builds detailed error messages with wire paths and tool stack traces. Compiled errors are raw JavaScript errors. Less helpful for debugging, but production errors go to monitoring systems anyway. + +- **`new Function()` required.** The compiler evaluates generated code via `new AsyncFunction(...)`, which means it doesn't work in environments that disallow `eval` — like Cloudflare Workers or Deno Deploy with default CSP. The runtime works everywhere. + +## What We Learned + +### 1. Interpreters have a floor; compilers don't + +No matter how much we optimized the `ExecutionTree`, it had a structural minimum cost per request: create a context, resolve wires, manage state. The compiler eliminates that floor entirely. The generated code is _the program_ — there's no framework overhead to optimize away. + +This is the same insight that drives projects like LuaJIT, PyPy, and GraalJS. Once your interpreter pattern is mature and well-understood, compiling to native (or near-native) code is the next performance frontier. + +### 2. Compile once, run many is the right caching model + +The `WeakMap>` cache means compilation happens exactly once per document lifetime. The WeakMap key on the document object means: + +- No cache invalidation logic needed +- Garbage collected when the document is released +- Zero overhead on the hot path (it's a Map lookup) + +We worried about `new AsyncFunction()` being slow — and it is, relatively (~0.5ms per compilation). But it happens once. For a production service handling thousands of requests per second, that 0.5ms is amortized to essentially zero. + +### 3. Code generation is simpler than you'd think + +The codegen module is [~1,500 lines](https://github.com/stackables/bridge/blob/main/packages/bridge-compiler/src/codegen.ts). It doesn't use a code generation framework, templates, or an IR. It builds JavaScript strings directly: + +```typescript +lines.push( + ` const ${tool.varName} = await __call(tools[${JSON.stringify(tool.toolName)}], ${inputObj});`, +); +``` + +String concatenation producing JavaScript source code. It's not elegant, but it's correct, testable, and easy to debug — you can `console.log(code)` and read what it produces. + +The topological sort, ToolDef resolution, and wire-to-expression conversion are all straightforward tree walks over the existing AST. We didn't need to invent new data structures — the AST already contains everything the compiler needs. + +### 4. The 80/20 of feature coverage + +We started by supporting pull wires and constants. That covered ~40% of real bridges. Then arrays, which got us to ~70%. Then ToolDefs, catch fallbacks, and force statements — 95%. The long tail (define blocks, alias, overdefinition, break/continue, string interpolation) required more code but fewer new architectural ideas. + +The key decision was shipping early with clear error messages for unsupported features: + +``` +Error: Bridge compilation failed for 'Query.complex': +Unknown reference: __define_in_secureProfile:Query:complex +``` + +Users could try the compiler, hit a missing feature, and fall back to the runtime — all at the bridge level, not the application level. + +### 5. Shared tests are the foundation + +The 150 shared data-driven tests are the single most important artifact. Each test case is a `{ bridgeText, operation, input, tools, expected }` tuple that runs through both execution paths: + +```typescript +const rtResult = await executeBridge({ document, operation, input, tools }); +const aotResult = await executeAot({ document, operation, input, tools }); +assert.deepEqual(aotResult.data, rtResult.data); +``` + +When we added a new feature to the compiler, we didn't have to guess if it matched the runtime — the test told us. When we found a runtime bug through compiler testing, we fixed it in both places simultaneously. + +### 6. LLMs are surprisingly good at code generation... for code generators + +An LLM helped write much of the initial codegen — emitting JavaScript from AST nodes is the kind of repetitive, pattern-based work where LLMs excel. The human added the architectural decisions (topological sort, caching model, internal tool inlining) and the LLM filled in the wire-to-expression conversion, fallback chain emission, and array mapping code generation. + +The feedback loop was fast: write a test, ask the LLM to make it pass, check the generated JavaScript looks right, run the full suite. We went from "proof of concept that handles pull wires" to "186 tests passing with full feature coverage" in three focused sessions. + +## The Compound Story + +Step back and look at the full arc: + +| Phase | What we did | Array 1,000 ops/sec | vs. original | +| ---------------------- | --------------------------- | ------------------- | ------------ | +| Original engine | Unoptimized interpreter | ~258 | — | +| After 12 optimizations | Profiling-driven micro-opts | ~2,980 | **11.5×** | +| After compiler | AOT code generation | ~29,300 | **113×** | + +From 258 ops/sec to 29,300 ops/sec. A **113× improvement** through two distinct phases: first, optimize the interpreter until it hits its architectural ceiling; then, build a compiler that eliminates the architecture entirely. + +Neither phase alone would have gotten here. The interpreter optimizations taught us _what_ the overhead was — which is exactly the knowledge needed to design a compiler that eliminates it. The `MaybePromise` pattern taught us about async overhead. The pre-computed keys taught us about string allocation. The shadow tree batching taught us about per-element costs. Each lesson from the interpreter became a design requirement for the compiler. + +## Trying It + +The compiler is experimental but feature-complete.
