An interactive documentation explorer for SWMManywhere, the open-source Python project for synthesizing urban drainage network models anywhere in the world.
Repository: SWMMEnablement/Swmmanywhere-Explorer
Replit app: replit.com/@robertdickinson/Swmmanywhere-Explorer
SWMManywhere Explorer is a single-page interactive documentation application built to make the SWMManywhere project easier to understand. Rather than presenting documentation as a long static text page, it organizes the project into visual, navigable sections that explain the workflow, codebase structure, graph functions, data sources, parameters, and metrics used by SWMManywhere. [page:49]
The project is designed as a frontend-only React application. According to replit.md, all content is static and embedded directly in client/src/lib/data.ts, which means the app does not depend on a database or backend API for core functionality. [page:49]
This app is best understood as a documentation workspace for a more complex Python modeling project. Its purpose is to help users and developers explore the structure and logic of SWMManywhere through organized, interactive views instead of raw repository browsing. [page:49]
That makes it useful for:
- engineers trying to understand the SWMManywhere modeling pipeline,
- developers onboarding to the codebase,
- researchers reviewing graph-based drainage synthesis functions,
- and anyone who wants a cleaner overview than reading source files directly. [page:49]
The application includes 6 main tabbed sections, each focused on a different dimension of the SWMManywhere project: [page:49]
- Pipeline — a step-by-step walkthrough of the SWMManywhere workflow. [page:49]
- File Tree — an interactive repository-style browser with search and expandable folders. [page:49]
- Graph Functions — a timeline or categorized view of graph-related functions in the project. [page:49]
- Data Sources — a guide to the external or internal data used by SWMManywhere. [page:49]
- Parameters — a reference to model configuration inputs and options. [page:49]
- Metrics — documentation of output measures, evaluation metrics, or analytical indicators. [page:49]
In addition, the app includes:
- dark/light mode with localStorage persistence, [page:49]
- responsive design across screen sizes, [page:49]
- and a documentation-oriented UI built with shadcn/ui and Tailwind. [page:49]
The app uses a simple but effective architecture focused on static documentation delivery. The documented design is: [page:49]
- Frontend-only application. [page:49]
- No database. [page:49]
- No backend API endpoints. [page:49]
- All structured content stored in
client/src/lib/data.ts. [page:49] - React + TypeScript UI with client-side routing and themed components. [page:49]
This approach keeps the app portable and easy to deploy, while also making the documentation deterministic and version-controlled with the source code. [page:49]
The repository layout shown on GitHub includes a full-stack-style skeleton, but the documentation specifically notes that the app itself is effectively frontend-only, with the key logic and content centered in the client. [page:49]

The repo language breakdown is 74.6% TypeScript, 20.9% JavaScript, 3.7% CSS, and 0.8% HTML, which is consistent with a TypeScript-heavy web application. [page:49]
replit.md identifies the following files as especially important: [page:49]
This is the main explorer page and likely contains the tabbed interface, section switching logic, and high-level page composition. It is the core of the user experience. [page:49]
This file contains all static documentation data, including the repository tree, pipeline stages, graph-function information, and related structured content. Because the app is frontend-only, this file acts as the project’s content backbone. [page:49]
This component manages the dark/light theme system, including persistence in localStorage. [page:49]
This is the root application component, responsible for routing and top-level composition. [page:49]
The Pipeline tab is intended to walk users through the major phases of the SWMManywhere workflow. Based on the project description, this likely serves as the conceptual introduction to how the Python tool assembles or synthesizes urban drainage network models. [page:49]
The File Tree tab provides an interactive repository browser with search and folder expansion. This is especially valuable for onboarding, because it helps users understand the codebase layout without needing to navigate GitHub manually. [page:49]
The Graph Functions tab is described as a timeline with category filtering, which suggests the app organizes graph-processing or network-construction functions into a browsable knowledge view. This is one of the more specialized parts of the explorer and likely reflects how central graph logic is to SWMManywhere. [page:49]
The Data Sources tab documents the data dependencies or source layers used by the SWMManywhere system. For a project that synthesizes drainage models geographically, this is likely one of the most important explanatory sections. [page:49]
The Parameters tab serves as a configuration reference for the inputs and options available in the upstream SWMManywhere tool. This can help users understand what can be tuned and where those controls influence the pipeline. [page:49]
The Metrics tab documents output measures, evaluation criteria, or reporting indicators used in the SWMManywhere workflow. This is useful for both validation and interpretation. [page:49]
The app uses shadcn/ui as its component library and is styled with Tailwind CSS. The design notes in replit.md specify: [page:49]
- Primary color: teal, hue 173. [page:49]
- Fonts: Inter for sans-serif text, Lora for serif text, and JetBrains Mono for monospace content. [page:49]
- Theme switching: dark/light mode with localStorage persistence. [page:49]
This gives the app a modern documentation aesthetic while keeping it responsive and easy to scan. [page:49]
The documentation and repository structure indicate the following stack: [page:49]
| Layer | Technology |
|---|---|
| Frontend framework | React [page:49] |
| Language | TypeScript [page:49] |
| Styling | Tailwind CSS [page:49] |
| Component library | shadcn/ui [page:49] |
| Theme system | LocalStorage-backed dark/light mode [page:49] |
| Build tooling | Vite, based on repo configuration files [page:49] |
| Runtime model | Static frontend with embedded data [page:49] |
Although the repo includes server and shared directories, the project documentation specifically says the app has no backend API endpoints and that all required content is embedded in the frontend. [page:49]
npm installnpm run devThe repository includes package.json, vite.config.ts, tailwind.config.ts, tsconfig.json, and components.json, which indicates a standard Vite + React + Tailwind development workflow. [page:49]
npm run buildBecause the project is frontend-only in practice, deployment should be straightforward once the client bundle is built. [page:49]
Many technical open-source projects are hard to understand because their documentation is fragmented across source files, configuration, and external references. SWMManywhere Explorer addresses that problem by turning a complex project into a structured, visual documentation tool. [page:49]
For engineering software in particular, that matters. Workflows involving graph functions, data sources, parameters, and model metrics are easier to understand when users can navigate them interactively rather than only reading source code or long markdown files. [page:49]
This repository is useful for:
- drainage and hydrologic modelers exploring SWMManywhere,
- developers onboarding to the SWMManywhere codebase,
- researchers studying graph-based urban drainage synthesis,
- and technical educators who want a cleaner way to explain the SWMManywhere pipeline. [page:49]
The repo currently shows GitHub’s Add a README prompt, which confirms that a public README is still missing. It has 5 commits on the main branch, and the visible history includes changes such as publishing the app and adding theme switching plus exploration-page layout improvements. [page:49]
The most important internal documentation file currently available is replit.md, which provides the concise architectural summary used here. Since the repository lacks a public README, adding this file would immediately make the project easier to understand for visitors, contributors, and future maintainers. [page:49]
