rspack-deno-plugin

Deno module resolution for rspack and rsbuild.

• Support for http:, https:, jsr:, and npm: specifiers.

This project learns esbuild_deno_loader

How to use

• You need to set "nodeModulesDir": "auto" in deno.json before start.

NPM Package

# install package
deno install npm:rspack-deno-plugin

• Use in rsbuild.config.ts

import { defineConfig } from '@rsbuild/core';
import RspackDenoPlugin from 'rspack-deno-plugin';

export default defineConfig({
  // ...
  tools: {
    rspack: {
      plugins: [new RspackDenoPlugin()],
    },
  },
});

• Use in rspack.config.ts

import { defineConfig } from '@rspack/cli';
import RspackDenoPlugin from 'rspack-deno-plugin';

export default defineConfig({
  // ...
  plugins: [new RspackDenoPlugin()],
});

JSR Package

• Can only be run with rsbuild api.

# install package
deno install jsr:@snowman/rspack-deno-plugin

// create rsbuild script file like rsbuild-script.ts
import { createRsbuild } from '@rsbuild/core';
import RspackDenoPlugin from '@snowman/rspack-deno-plugin';

const rsbuild = await createRsbuild({
  rsbuildConfig: {
    tools: {
      rspack: {
        // add rspack plugin
        plugins: [new RspackDenoPlugin()],
      },
    },
  },
});

// build
await rsbuild.build();

// preview
await rsbuild.preview();

// dev
await rsbuild.startDevServer();

# run rsbuild script
deno --allow-all ./rsbuild-script.ts

How it works

• npm: specifier: Resolve node_modules like node.
• http:, https:, jsr: specifiers: Use deno info command to resolve deno local cache.
• file:, data: specifiers: Resolve by rspack.

Coming soon

• Support resolve npm local deno cache.
• Add test code and CI/CD.
