+# SWC next formatter PoC
+
+This branch replaces the default Yuku parser in `rs fmt` with SWC Next 0.2.0 while retaining Prettier's ESTree printer and the existing formatting adapter.
+
+`swc_next_bridge = "=0.2.0"` compiles parsing and serialization into the existing rstack native binding. A thin NAPI function returns a Buffer to `@swc-next/decoder@0.2.0`; the generated loader is resolved lazily when parsing starts. No parser npm package or separate SWC Next native binary is installed.
+
+Inferred JavaScript, JSX, TypeScript, TSX, and embedded script formatting use SWC Next. Explicit `babel` and `typescript` options still select Prettier's own parsers, and project plugins retain precedence. The experimental explicit parser names are `swc-next` and `swc-next-ts`, replacing `yuku` and `yuku-ts`.
+
+The cache namespace includes the parser version and integration route so switching between the original formatter and either PoC cannot reuse stale formatting results. The decoder and Rust serializer must be upgraded together; all SWC Next packages in this PoC are locked to 0.2.0.
+
+## Try it
+
+```sh
+pnpm install
+pnpm build
+pnpm --filter rstack build:native
+printf 'const view=<Component value={{foo:1}} />' | pnpm exec rs fmt --stdin-filepath example.tsx
+pnpm test
+pnpm check
+```
+
+Native changes also require `cargo fmt --all -- --check`, `cargo clippy --workspace --all-targets --locked -- -D warnings`, and `cargo test --workspace --locked`.
+
+## Compatibility and limits
+
+SWC Next 0.2.0 accepts function implementations in declaration files, for example `export function value() { return 1; }` in `example.d.ts`. Yuku previously rejected this with an ambient-context diagnostic. The tests explicitly record this upstream difference; valid declarations, comments, Unicode locations, JSX/TSX, CommonJS, pragmas, and syntax errors remain covered. No fallback to another parser hides SWC Next errors.
+
+Validation is on macOS arm64 with the repository's Node.js, pnpm, and Rust versions. The complete formatter/CLI suite covers worker execution, stdin, LSP, Vue, Svelte, and caching. Cross-platform binaries and formatter-wide conformance against Prettier's upstream corpus have not been validated. No throughput advantage is claimed by this PoC.

+Rstack CLI includes a formatter built on [Prettier](https://prettier.io/). Compared with running Prettier directly, `rs fmt` includes the following:
 
 - **Parallel formatting**: Files are formatted concurrently in a worker pool.
-- **Yuku parser**: The high-performance [Yuku](https://yuku.fyi/) parser is used by default for JavaScript, JSX, and TypeScript files.
+- **SWC Next parser**: The [SWC Next](https://github.com/swc-project/swc-next) parser is used by default for JavaScript, JSX, and TypeScript files.
 - **Persistent cache**: Content-based results let later runs skip formatting unchanged files.
 
 `rs fmt` supports Prettier options and plugins and adds built-in capabilities such as [sorting package.json fields](#sort-package-json).

+Rstack CLI 提供了基于 [Prettier](https://prettier.io/) 的格式化工具。相比直接使用 Prettier，`rs fmt` 提供了以下能力：
 
 - **并行格式化**：通过 worker 池并行格式化文件。
-- **Yuku 解析器**：默认使用高性能的 [Yuku](https://yuku.fyi/) 解析器处理 JavaScript、JSX 和 TypeScript 文件。
+- **SWC Next 解析器**：默认使用 [SWC Next](https://github.com/swc-project/swc-next) 解析器处理 JavaScript、JSX 和 TypeScript 文件。
 - **持久化缓存**：基于文件内容缓存结果，后续运行可以跳过未变化文件的格式化。
 
 `rs fmt` 兼容 Prettier 的选项和插件，并提供更多内置能力，例如支持[排序 package.json 字段](#sort-package-json)。
