rollup-plugin-swc

• New feature viteMinify to use swc's minification in Vite.

  • When used, it will disable Vite's built-in minification and use swc's minification instead.

  import { defineConfig } from 'vite';
  import { viteMinify } from 'rollup-plugin-swc3'
  
  export default defineConfig({
    plugins: [
      viteMinify({
        // swc's minify option here
        // mangle: {}
        // compress: {}
      }),
    ],
  })
  

• Fix #63
  • Previously, rollup-plugin-swc3 only handled relative compilerOptions.baseUrl when compilerOptions.paths is specified. It is fixed in #64, now rollup-plugin-swc3 will handle relative compilerOptions.baseUrl as long as it is specified.

• Fix #58
  • rollup-plugin-swc3 now will only perform module resolution inside the files specified in include and exclude options.
• Replace rollup-swc-preserve-directives with rollup-preserve-directives

0.10.2

• Add warning messages when tsconfig is invalid
• Add rollup 4 official support

• Fix #41
  • rollup-plugin-swc3 now will always provide baseUrl (resolve to an absolute path) to swc as long as the paths is specified in the tsconfig.json or jsconfig.json being read.

• Fix #41
  • rollup-plugin-swc3 now will resolve baseUrl to an absolute path against the tsconfig.json and jsconfig.json being read.
  • This is to align with the behavior change of the swc: https://github.com/swc-project/swc/issues/7799 and https://github.com/swc-project/swc/issues/7800.

The support for 'use client' and 'use server' has been separated into a standalone rollup plugin rollup-swc-preserve-directives, maintained by @huozhi and me. The previous preserveUseDirective named export is retained for the backward compatibility.

• Add support for bundling library for React Server Component with the proper 'use client' and 'use server' directives handling:

  • Merge duplicated directives in the final bundles
  • Multiple output chunks will have their own separated directives, useful when bundling client only code and server only code in different bundles.
  • Not enabled by default. manually opt-in by changing two lines of code in your rollup.config.js:

  // rollup.config.js
  // Import `preserveUseDirective` from `rollup-plugin-swc3`...
  - import { swc } from 'rollup-plugin-swc3';
  + import { swc, preserveUseDirective } from 'rollup-plugin-swc3';
  
  export default {
    input: 'xxxx',
    output: {},
    plugins: [
      swc(),
  +   preserveUseDirective()
    ];
  }
  

0.8.2

• Enable CI auto publish release + npm provenance

• Fix TypeScript declaration of include and exclude option (#32)

• Add new option extensions.
  • Along with include / exclude, this provides a granular way to specify the files that will be processed by the plugin.
  • For extensionless imports, the plugin will search and resolve files for extensions in the order specified.

• Add Rollup 3.0.0 support.
  • rollup-plugin-swc now supports both Rollup 2 and Rollup 3.

• Supports extends from tsconfig.json/jsconfig.json.
• Supports passing a full path of a tsconfig.json/jsconfig.json file to tsconfig option.
• When finding the nearest tsconfig.json/jsconfig.json from the source file that is currently being transpiled, rollup-plugin-swc's behavior is now aligned with tsc.

• rollup-plugin-swc now also respects jsx option from tsconfig.json when no corresponding swc option is provided.
  • jsxImportSource from tsconfig.json will be passed to swc's jsc.transform.react.importSource
  • if tsconfig.json specifies jsx: react-jsx or jsx: react-jsxdev, rollup-plugin-swc will set jsx.tramsform.react.runtime to automatic, otherwise it will be classic.
    • Currently, swc doesn't support preserving JSX, and will always transpile JSX into javascript code.
  • rollup-plugin-swc will also set jsx.tramsform.react.development to true if tsconfig.json specifies jsx: react-jsxdev.

Remove unused dependency (@huozhi #20)

• Fix some minor issues
• Changelog for 0.4.0

• Automatically pass rollup's file id to swc's filename option.
  • It should help swc find the .swcrc, and also enables some other swc's functionality
• Automatically mapping .ts/.tsx to .mjs/.js/.cjs/.jsx.
  • When using native ESM, import path requires .js/.jsx extension for TypeScript with "moduleResolution": "Node16". So rollup-plugin-swc will now try all possible extensions.
  • E.g. if you write import Foo from 'foo.jsx', rollup-plugin-swc will search for foo.ts, foo.tsx, foo.mjs, foo.js, foo.jsx.
  • PRs are welcome if you want to make rollup-plugin-swc more spec compliant.

• Completely disable swc minify during rollup's transform phase.
  • Now all minify will be done in rollup's renderChunk phase, which is a one-pass process, resulting in even faster build performance.
• Remove the workaround for rollup's virtual module that is introduced in 0.1.2 (https://github.com/SukkaW/rollup-plugin-swc/pull/1)
  • swc has fixed the issue, and the corresponding test case has been added in https://github.com/swc-project/swc/pull/4255
  • The peerDependencies of swc has been updated to >=1.2.165. You will need to bump the version of swc to 1.2.165 or higher after this release.

• Standalone minify plugin
• Support reading baseUrl and paths from your tsconfig.json (and jsconfig.json).
  • These fields will be passed to swc directly. They won't affect how rollup resolves your imports. Please use other plugins to resolve your imports' aliases (e.g., add rollup-plugin-typescript-paths or rollup-plugin-tsconfig-paths before @rollup/plugin-node-resolve).

• Add .mjs extension support
• Export a default for use with rollup's --configPlugin
