From 57e881b279be2bc4c0792703edd9041ad1de8e7c Mon Sep 17 00:00:00 2001 From: Jayprakash Pal Date: Mon, 9 Feb 2026 00:50:18 +0530 Subject: [PATCH 1/6] Split parsing and generation; add dep symbol table Refactor package compiler to accept dependencyPaths and build a global symbol table from dependencies' exports.json (prefers explicit URIs, falls back to inferred package: URIs). Split file processing into _parseFile and _generateJS phases, populate local exports into the global table, and run JS generation with an updated importRewriter that preserves package: URIs (converts .dart -> .js). Add verbose/debug logging and diagnostics for symbol resolution and package scanning. Fix declaration extraction: propagate extension-type metadata, log debug info, and record generic typedefs. Also include many generated JS artifacts, source maps and package metadata updates (exports.json / package.json) across flutterjs_dart, foundation, services, widgets, engine, gen, runtime, tools and other packages. --- .../lib/src/package_compiler.dart | 216 ++++-- .../analysis/visitors/declaration_pass.dart | 46 +- packages/flutterjs_dart/dist/async/index.js | 6 +- .../flutterjs_dart/dist/async/index.js.map | 6 +- packages/flutterjs_dart/dist/async/stream.js | 2 + .../flutterjs_dart/dist/async/stream.js.map | 7 + .../flutterjs_dart/dist/async/stream_view.js | 2 + .../dist/async/stream_view.js.map | 7 + .../flutterjs_dart/dist/collection/index.js | 6 +- .../dist/collection/index.js.map | 6 +- .../dist/collection/priority_queue.js | 4 -

tracking, and package improvements MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Core compiler: - Add ImportExportTracker and ImportExportModel for accurate cross-file import analysis - Add EnumDecl IR node and EnumCodeGenerator for proper enum โ†’ JS object translation - Fix CascadeExpressionIR scanning in ImportAnalyzer and FileCodeGen - Fix null comparison semantics (== null uses loose equality to catch undefined) - Fix Map cast to use typeof check instead of instanceof Map - Remove hardcoded identifier hacks in ExpressionCodeGenerator Node.js server target: - Add flutterjs_server package (Dart API + JS runtime with HTTP server, router, middleware) - Add dart_api example: full REST API demo compiled from Dart to Node.js - PackageRegistry: filter web-only @flutterjs packages for node target builds - RuntimePackageManager: also link @flutterjs/X as flutterjs_X in root node_modules - RunCommand: auto-link node_modules before starting node server (_ensureNodeModulesForNodeTarget) Import generation: - GlobalSymbolTable wired to ModelToJSPipeline after package manifests load - PackageRegistry.buildGlobalSymbolTable() maps symbols to full package: URIs - Fix hardcoded material imports registered in symbolToPath to prevent duplicates Package updates: - flutterjs_foundation, flutterjs_gestures, flutterjs_material, flutterjs_services, flutterjs_widgets: updated exports.json, build.js, src/index.js - flutterjs_dart: add ui_web dist, pubspec.yaml - flutter_web_plugins: add JS package - Add tool/ scripts for build, check, fix-imports, reset Co-Authored-By: Claude Sonnet 4.5 --- PROJECT_HANDOVER.md | 96 --- examples/dart_api/.gitignore | 45 ++ examples/dart_api/.metadata | 45 ++ examples/dart_api/DEBUG_GEN.txt |

to the web without the heavy runtime cost of CanvasKit or Wasm. Instead of drawing pixels to a canvas, **FlutterJS transpiles Dart code into idiomatic, readable JavaScript** that manipulates the DOM directly using a lightweight Virtual DOM (VNode) system. - -**Goal**: Write Dart (Widgets, State, Logic) -> Run as optimized HTML/CSS/JS. - -## ๐Ÿ—๏ธ System Architecture - -The project consists of three main layers that work together to transform Dart code into a running web application: - -### 1. The Compiler (Dart Side) -Located in `packages/flutterjs_tools` and `packages/flutterjs_gen`. -* **Role**: Analyzes Dart source code, extracts an Intermediate Representation (IR), and transpiles it to JavaScript. -* **Key Logic**: - * `IRGenerator`: Parses Dart code to understand classes, builds methods, and widget structures. - * `JSCodeGenerator`: Converts the IR into valid ES Module JavaScript. - * **Expression Handling**: Handles complex Dart concepts like `throw` expressions, `as` casts, and `??` operators during transpilation. - -### 2. The Engine (Node.js Side) -Located in `packages/flutterjs_engine`. -* **Role**: Orchestrates the build process, manages dependencies, and serves the application. -* **Key Components**: - * **Build Pipeline**: Analyzing, Transforming, and Generating outputs. - * **Dev Server**: Express-based server with Hot Module Replacement (HMR) support. - * **Asset Generation**: Creates `index.html`, `app.js`, and `styles.css`. - -### 3. The Runtime (Browser Side) -Located in `packages/flutterjs_runtime`, `packages/flutterjs_widgets`, `packages/flutterjs_material`, etc. -* **Role**: The JavaScript libraries that run in the browser. -* **Key Concepts**: - * **VNode System**: A lightweight virtual DOM implementation. - * **Widget Tree**: Replicates Flutter's widget tree structure (Stateless/Stateful). - * **Reconciliation**: Diffs VNodes to update the real DOM efficiently. - -## ๐Ÿ“‚ Repository Structure - -```text -flutterjs/ -โ”œโ”€โ”€ bin/ # Global CLI entry point (flutterjs.dart) -โ”œโ”€โ”€ examples/ # Test applications -โ”‚ โ”œโ”€โ”€ counter/ # The canonical "Hello World" -โ”‚ โ””โ”€โ”€ pub_test_app/ # Complex dependency integration tests -โ”œโ”€โ”€ packages/ -โ”‚ โ”œโ”€โ”€ flutterjs_tools/ # Main Dart CLI & Transpiler logic -โ”‚ โ”œโ”€โ”€ flutterjs_engine/ # Node.js Build System & Dev Server -โ”‚ โ”œโ”€โ”€ flutterjs_gen/ # IR Generation & Code Gen utilities -โ”‚ โ”œโ”€โ”€ flutterjs_runtime/ # Core JS Runtime (runApp, setState) -โ”‚ โ”œโ”€โ”€ flutterjs_widgets/ # Base Widget implementations -โ”‚ โ”œโ”€โ”€ flutterjs_material/ # Material Design components -โ”‚ โ””โ”€โ”€ flutterjs_analyzer/ # JS-based Analysis tools -``` - -## ๐Ÿš€ Workflows & Usage - -### Standard Development Cycle -1. **Write Dart**: User writes standard Flutter code in `lib/`. -2. **Run CLI**: `dart bin/flutterjs.dart run --to-js --serve`. -3. **Transpilation**: - * CLI compiles Dart -> `.js` (ESM) in `build/flutterjs/src/`. - * CLI generates `flutterjs.config.js`. -4. **Serving**: - * Engine starts, reads config. - * Generates `app.js` (bootstrap) and `index.html`. - * Serves assets via localhost. - -### Build Implementation Details -* **Direct JS Generation**: We now generate `.js` files directly (no intermediate `.fjs`). -* **Entry Point**: The system defaults to `src/main.js`. -* **Config**: `flutterjs.config.js` controls the engine's behavior. - -## ๐Ÿ“ Current Technical Status - -### โœ… What Works -* **Direct JS Transpilation**: `.dart` files are successfully converted to `.js` ES Modules. -* **Expression Support**: `throw`, `as`, `is`, `??` are correctly handled in JS. -* **Basic Widgets**: `Container`, `Column`, `Row`, `Text`, `Scaffold`, `AppBar`, `FloatingActionButton`. -* **State Management**: `setState` triggers re-renders via the VNode system. -* **Dev Server**: Starts, serves assets, and supports HMR signals. -* **Package Support**: Can compile dependencies like `collection` (with some caveats on complex exports). - -### ๐Ÿšง Works in Progress / Limitations -* **Layout System**: Flex layout (Row/Column) is basic CSS-based; complex main/cross axis behavior may need tuning. -* **Dart Core Polyfills**: `dart:core` mapping is partial. Missing advanced `Map`, `Set`, or `List` methods might cause runtime errors. -* **Complex Dependencies**: Packages with heavy use of `dart:io` or `dart:isolate` will fail. - -## ๐Ÿ› Known Issues / Debugging Tips -1. **"Entry file not found"**: Usually means `flutterjs.config.js` is stale (pointing to `.fjs`). **Fix**: Delete the config file and re-run the build. -2. **Engine Version Mismatch**: If `dart run` fails to start the server, it might be running a stale `flutterjs-win.exe`. **Fix**: Ensure `engine_bridge.dart` is prioritizing `packages/flutterjs_engine/bin/index.js` (Node source). -3. **Port Conflicts**: If the CLI crashes, the Node server might stay persistent. **Fix**: Kill the `node` process manually. -3. **Missing Imports**: If generated JS is missing imports, check `file_code_gen.dart` in `flutterjs_gen`. - -## ๐Ÿ”ฎ Roadmap -1. **Complete Runtime Polyfills**: Solidify `@flutterjs/dart` to fully emulate Dart's core library behavior. -2. **Layout System V2**: Implement a more robust layout solver for `Stack`, `Positioned`, and advanced Flex scenarios. -3. **Production Minification**: Hook up `terser` or `esbuild` in the engine for production builds (`flutterjs build`). diff --git a/examples/dart_api/.gitignore b/examples/dart_api/.gitignore new file mode 100644 index 00000000..3820a95c --- /dev/null +++ b/examples/dart_api/.gitignore @@ -0,0
