esbuild-plugin-transformer v0.1.0

esbuild-plugin-transformer

esbuild-plugin-transformer is a versatile plugin for esbuild that enables code transformation during the build process. It's a great tool for developers who want to customize their build configurations.

Installation

You can install esbuild-plugin-transformer via npm:

npm add esbuild-plugin-transformer -D

Or if you prefer using pnpm:

pnpm add esbuild-plugin-transformer -D

Usage

esbuild-plugin-transformer can be used with different compilers like Babel or SWC. Here are some examples of how to use it:

Babel

import { build } from 'esbuild'
import { transformer } from 'esbuild-plugin-transformer'
import babelPresetEnv from '@babel/preset-env'

const options = {
  bundle: false,
  format: 'esm'
}

build({
  ...options,
  target: 'es5',
  plugins: [
    transformer({
      compiler: 'babel',
      options: {
        presets: [[babelPresetEnv, { modules: false }]]
      }
    })
  ]
})

SWC

import { build } from 'esbuild'
import { transformer } from 'esbuild-plugin-transformer'

const options = {
  bundle: false,
  format: 'esm'
}

build({
  ...options,
  target: 'es5',
  plugins: [
    transformer({
      compiler: 'swc',
      options: { script: true, minify: true }
    })
  ]
})

In the above examples, we first import the necessary modules, then define our build options. After that, we call the build function from esbuild, spreading our options, defining the target version of ECMAScript, and finally, adding our transformer plugin with the desired compiler and its options.
