Thanks for the contribution. There are issues to fix before this merges.
Issues:
-
File is an orphan — not wired into the package public API
File: packages/jsx/src/focus_cleanup.ts
Problem: The new file is never imported or called from the JSX reconciler/unmount path, so the fix for #1355 is never actually invoked. The function exists in isolation.
Fix: Call `autoBlurNode` from the unmount code path in the JSX reconciler (wherever `unmountFiber` or equivalent is called) and export it from `packages/jsx/src/index.ts` if it is part of the public API. -
No tests
File: packages/jsx/src/focus_cleanup.ts
Problem: The fix for a focus trap lock-up should be verified with at least one test that mounts a focused node, unmounts it, and asserts blur was called.
Fix: Add a test file `focus_cleanup.test.ts`. -
CI is missing `build-and-test`
Problem: Only path-labels, star-check, and CodeRabbit passed. The mandatory build-and-test job never ran.
Fix: Rebase onto latest main to trigger a full CI run.
Checklist:
- Wire autoBlurNode into the unmount code path
- Export from package index if public
- Add focus_cleanup.test.ts
- build-and-test CI passes
- Tests pass (bun vitest run)

No integration with JSX unmount lifecycle
Problem: The issue (#1355) asks to "fix focus trap lock-up when removing focused nodes from JSX DOM". The PR only adds a standalone helper but never wires it into the JSX fiber's unmount path (e.g.,destroyFiberor the node removal hook). The bug described in the issue is therefore not fixed.
Fix: CallautoBlurNodefrom the relevant unmount hook/fiber cleanup path so it runs automatically when a focused node is removed, without requiring callers to invoke it manually. -
No tests
Problem: There are no tests verifying that the helper correctly blurs the focused node and is a no-op when the node is not focused.
Fix: Addpackages/jsx/src/focus_cleanup.test.tscovering both branches.

[No integration with unmount lifecycle]
File: packages/jsx/src/focus_cleanup.ts
Problem:autoBlurNodeis a standalone helper that is never called during actual component unmount. The fix for #1355 requires hooking into the JSX reconciler's unmount path so that when a focused node is removed from the tree, blur is triggered automatically.
Fix: CallautoBlurNode(or equivalent logic) inside the reconciler's node-removal / unmount routine, not as an isolated export. -
[No tests]
File: packages/jsx/src/focus_cleanup.test.ts (missing)
Problem: No tests verify that blur is called when a focused node is unmounted, or that non-focused nodes are not blurred.

Issues:
-
Implementation does not fulfill the linked issue's requirements / does not fix the lock-up
File: packages/jsx/src/focus_cleanup.ts, packages/jsx/src/hooks/useFocus.ts
Problem: The PR adds anautoBlurNodehelper but never calls it from anywhere. Issue #1355 requires: (1) monitoring the lifecycle of focused nodes in the focus context, (2) automatically invoking blur when a focused node unmounts, and (3) auto-routing focus to the nearest focusable ancestor or app root as fallback.useFocus(packages/jsx/src/hooks/useFocus.ts) has nouseEffectcleanup/unmount handler that callsautoBlurNode, so the original lock-up bug (focus manager pointing at a non-existent node ID after unmount) is not fixed by this PR.
Fix: InuseFocus, add auseEffectcleanup function (returned from the existing effect or a new one) that callsautoBlurNode(ctx, id)on unmount, so focus is released if this node was focused when removed. Additionally implement fallback focus routing to the nearest focusable ancestor (or app root) instead of leaving focus null, per the issue. Add a test simulating conditional unmounting of a focused input and asserting that subsequent keyboard input is not locked up. -
No tests included
File: packages/jsx/src/focus_cleanup.ts
Problem: A critical-severity bugfix PR with zero test coverage, including no regression test for the lock-up scenario described in the issue.
Fix: Add a test (e.g. in useFocus.test.ts or a new focus_cleanup.test.ts) that mounts a focused component, unmounts it, and verifies the focus manager'sfocusedstate is cleared/reassigned and that focus/keyboard handling continues to work afterward.

Issues:

New helper is never wired into the focus manager / unmount lifecycle
File: packages/jsx/src/focus_cleanup.ts, line 1-8
Problem:autoBlurNode()is added but not called from anywhere - it's not hooked into any component unmount lifecycle in @termuijs/jsx. The focus trap lock-up described in #1355 (keyboard input locks up when a focused node is unmounted) is not actually fixed.
Fix: HookautoBlurNode(or equivalent logic) into the JSX reconciler/unmount path so that when a focused node is removed from the tree,focusManager.blur()is invoked automatically and focus is re-routed to the nearest focusable ancestor or app root, per the issue's proposed solution. -
Missing regression test reproducing the lock-up
Problem: No test simulates conditionally unmounting a focused input (e.g. closing a modal or filtering a focused list item) and verifying that subsequent keyboard input is no longer locked up. This is required by #1355 and is critical to confirm the fix works against the real reconciler, not just the standalone helper.
Fix: Add a test in packages/jsx that mounts a focusable component, focuses it, unmounts it, and asserts the focus manager's focused state is cleared/re-routed and that subsequent key events are dispatched normally (no lock-up). -
No fallback/re-routing logic
File: packages/jsx/src/focus_cleanup.ts
Problem:autoBlurNodeonly callsblur(); it does not implement the "auto-route focus to nearest focusable ancestor or fallback to app root" behavior described in #1355.
Fix: Extend the cleanup logic to attempt focusing the nearest focusable ancestor before falling back to blur/app root.

In `@packages/jsx/src/focus_cleanup.test.ts`:
- Around line 38-47: The tests in focus_cleanup.test.ts are using direct fiber
and context manipulation (runEffects, destroyFiber) instead of the real
rendering path, which bypasses actual unmount behavior. Replace the current test
implementations with integration-style tests that mount focused UI components
using a real Screen instance, render them via updateRect() and render() calls,
conditionally unmount the focused component, and then assert the observable
focus routing or blur behavior. This ensures tests validate the real
conditional-unmount behavior as described in the bug, following the requirement
that packages/**/*.test.{ts,tsx} tests must use real Screen and render cycles
rather than internal fiber/context manipulation.
- Line 65: Remove or properly justify all `as any` type assertions in the test
file per TypeScript guidelines. At line 65 in the assignment `mockWidget1.parent
= null as any`, remove the unnecessary `as any` assertion since the parent
property is already typed as null on line 63. At lines 70 and 78 where
`(globalThis as any)` is used to access non-standard properties, add inline
comments explaining why the type assertion is required (e.g., accessing
properties that don't exist on the standard globalThis type). At line 74 in the
`autoBlurNode(mockContextValue as any, ...)` call, remove the `as any` assertion
since mockContextValue is already properly typed, or alternatively add an inline
comment if the assertion is genuinely necessary for the test.
In `@packages/jsx/src/focus_cleanup.ts`:
- Around line 35-43: The fallback focus routing in the loop starting at the
instances Map iteration is non-deterministic because it picks the first
focusable widget based on Map insertion order rather than a stable, app-level
fallback target. Replace the logic that iterates through instances.keys() and
selects the first focusable widget (where w.focusable && w.id !== nodeId) with a
deterministic approach that routes focus to a consistent, root-level fallback
node or a designated primary focus target, ensuring predictable focus behavior
during unmount cleanup instead of relying on Map iteration order.

…-style tests and fix non-deterministic fallback routing

@Karanjot786 I have addressed the review suggestions for the focus cleanup logic. The fallback routing is now deterministic (using alphabetical ID sorting), and the unit tests have been rewritten to use clean integration-style rendering and unmounting instead of manual fiber/context manipulation.

File: packages/jsx/src/focus_cleanup.ts, lines 9 and 13
Problem:const instances = (globalThis as any).__termuijs_instancesandlet widget: any = nulluse unsafeanycasts in a public-facing production source file. This bypasses TypeScript's type safety and signals that the implementation is coupling to undocumented internals without a proper typed contract.
Fix: Declare a typed interface for the global (e.g.interface TermuiGlobal { __termuijs_instances?: Map<{ id: string; focusable?: boolean; parent: unknown }, unknown> }) and cast via(globalThis as unknown as TermuiGlobal), or import the widget type from the reconciler. Replacelet widget: anywith the proper typed variable. -
Private global access via
as anyin tests
File: packages/jsx/src/focus_cleanup.test.ts, multiple lines
Problem: Tests use(globalThis as any).__termuijs_instancesto read and overwrite reconciler-internal state. This is private field access throughas anyin tests — a blocking pattern in this repo. Tests must exercise observable behavior through the public API (mount, render, unmount cycles), not by reaching into undocumented globals.
Fix: Replace the third test (falls back to routing focus to fallback deterministically) with an integration-style test that renders two focusable components, focuses one, unmounts it, and asserts the other is now focused using public hook return values or render output. Do not manipulate__termuijs_instancesdirectly. -
PR will regress the exhaustive-deps fix from PR #1430

Problem: This PR was branched from the originaluseFocuscommit (before PR #1430 landed). The diff showsuseEffectwith[]deps and// eslint-disable-next-line react-hooks/exhaustive-deps. Main now has[autoFocus, focused, focus, id]as the dependency array (merged via #1430). When this PR merges, the diff will reapply the old[]deps, silently regressing the fix.
Fix: Rebase this branch onto current main (git rebase main), resolve the conflict inuseFocus.tsso that the cleanup return is added inside the existing effect that has the correct[autoFocus, focused, focus, id]deps array. Theeslint-disablecomment and the[]deps must not be present in the merged result.

as anycasts on public exported function to access internal globals
File: packages/jsx/src/focus_cleanup.ts, lines 8-16, 32-48
Problem:autoBlurNodeis a public API (exported from index.ts) and its entire implementation relies on(globalThis as any).__termuijs_instances— a private internal global — pluslet widget: any,w.id as any,w.focusable as any,current.parent as any, etc. Usingas anyto reach into undocumented internal state makes the function fragile, untestable via the public API, and tightly couples the cleanup logic to an implementation detail that can change at any time. If__termuijs_instancesis a stable internal registry it should be typed and exposed through a proper internal accessor (e.g.getInstanceRegistry(): Map<Widget, Instance>in reconciler.ts), andautoBlurNodeshould accept a typed widget tree / registry parameter rather than reading an untyped global.
Fix: Either (a) pass the focusable widget list as an explicit typed parameter toautoBlurNodeso callers provide the data, or (b) create a typed internal accessor in reconciler.ts and import it — removing allas anycasts. The public signature ofautoBlurNodeshould not require knowledge of an untyped internal global. -
Tests access the same untyped internal global directly
File: packages/jsx/src/focus_cleanup.test.ts, lines 16, 29, 31, 64, 66, 103, 105
Problem:(globalThis as any).__termuijs_instancesin tests is equivalent to the banned(widget as any)._fieldpattern — it bypasses the public API to reach internal state and makes tests dependent on implementation details rather than observable behaviour. The test for "clears focus on unmount" also reconstructs arootInstancefrom the internal map instead of triggering the unmount through the public JSX render API.
Fix: Drive unmount behaviour through the publicreconcile/reRenderComponentsurface with a component that conditionally renders, then assert on the mockblur/focuscalls. Remove all direct reads/writes of__termuijs_instancesfrom test code.

- Line 13: Simplify the type annotation for the widget variable declaration by
removing the redundant type intersection. Since the Widget base class already
declares the id, focusable, and parent properties, change the widget variable
type from the full intersection type to simply Widget | null, eliminating the
unnecessary object type literal that duplicates properties already present in
the Widget class definition.

- Around line 38-40: The getInstanceMap() function in the test file is
recursively calling itself with no base case, causing a stack overflow. Remove
the broken local getInstanceMap() function definition (lines 38-40) and instead
import the real getInstanceMap() from the reconciler module which exports it at
line 49 of reconciler.ts. Update the import statement to include getInstanceMap
from the reconciler module so that all test calls to getInstanceMap() (at lines
52, 86, 117, 127, 136, 145, 159, 166) will use the correct implementation.

removing the redundant type intersection. Since the Widget base class already
declares the id, focusable, and parent properties, change the widget variable
type from the full intersection type to simply Widget | null, eliminating the
unnecessary object type literal that duplicates properties already present in
the Widget class definition.
In `@packages/jsx/src/reconciler.test.ts`:
- Around line 38-40: The getInstanceMap() function in the test file is
recursively calling itself with no base case, causing a stack overflow. Remove
the broken local getInstanceMap() function definition (lines 38-40) and instead
import the real getInstanceMap() from the reconciler module which exports it at
line 49 of reconciler.ts. Update the import statement to include getInstanceMap
from the reconciler module so that all test calls to getInstanceMap() (at lines
52, 86, 117, 127, 136, 145, 159, 166) will use the correct implementation.
In `@packages/testing/src/render.ts`:
- Around line 312-314: The file inconsistently accesses the instance map by
using both direct reads of globalThis.__termuijs_instances and the
getInstanceMap() accessor function. Replace all direct accesses to (globalThis
as any).__termuijs_instances at lines 312, 426, 516, and 576 with calls to
getInstanceMap() to match the pattern already established in the fireMouse
function, ensuring consistent and centralized instance map access throughout the
render.ts file.

Nitpick comments:
In `@packages/jsx/src/focus_cleanup.ts`:
- Around line 12-21: The linear search through the instance map by iterating
through instances.keys() to find a widget matching nodeId lacks context about
the design decision. Add a comment above the for loop that explains the
tradeoff: the instance map is keyed by Widget objects (not by id), which makes a
linear search necessary, and note that while this is O(n), it is generally
acceptable for typical widget counts in TUI applications. This comment will
clarify the intentional design decision for future maintainers.
In `@packages/jsx/src/hooks.ts`:
- Around line 345-347: The if block checking for `seen.has(key)` is empty and
provides no implementation despite the comment indicating conflicting
keybindings should be silently ignored. Either remove the entire empty if block
containing the conflict detection check, or add a clarifying comment inside the
empty block (such as a JSDoc or inline comment) that explicitly explains why no
action is being taken for conflicting keybindings.

Remove the redundant type intersection.
The

Infinite recursion in test helper causes stack overflow.
The
getInstanceMap()test helper (lines 38–40) calls itself recursively with no base case. This breaks thebeforeEachhook (line 44) and all tests that callgetInstanceMap()(lines 52, 86, 117, 127, 136, 145, 159, 166), causing immediate stack overflow at runtime.The reconciler exports the real
getInstanceMap()at line 49 ofreconciler.ts. Import and use it instead of the broken local function.🔧 Proposed fix
