@hyrious/esbuild-plugin-external

An esbuild plugin to help you compute and mark external modules manually.

Features

• Excludes dependencies and peerDependencies from package.json.
• Adds custom loader with { external: "./replacement.js" }.
• Automatically externalizes imports with pattern matching.

Usage

import external from '@hyrious/esbuild-plugin-external'

await esbuild.build({
  entryPoints: ['src/index.ts', 'src/cli.ts'],
  bundle: true,
  format: 'esm',
  platform: 'node',
  packages: 'bundle',
  plugins: [external()]
}).catch(() => process.exit(1))

Options

external({
  package: true,
  filter: /\.ts$/,
  auto: [{ filter: /\.js$/ }],
})

• package: Automatically mark dependencies and peer dependencies from package.json. This is enabled by default.

• filter: Filter in files to be enhanced to use import attribute with { external: "replace" }. This is disabled by default, you need to pass in a regex to make it work. Example:

  import * as mod from '../foo' with { external: "./foo.js" }
  // will be bundled into =>
  import * as mod from './foo.js'

• auto: Filter in paths to be externalized and perform a simple replacement to strip leading '../'s. This is disabled by default, you need to pass in a config to make it work. Example:

  // auto: [{ filter: /\.js$/ }]
  import * as mod from './index.js' // will be marked external
  import * as mod from '../foo.js' // will be externalized as './foo.js'
