browserslist-to-esbuild

Use browserslist with esbuild.

Allows you to use browserslist and pass the correct browsers to esbuild's target option.

Install

You have to install the browserslist package as well in your project:

npm install --save-dev browserslist browserslist-to-esbuild

yarn add --dev browserslist browserslist-to-esbuild

Usage

You can call browserslistToEsbuild() directly in your esbuild.mjs script, it will look for your browserslist config in either package.json or the .browserslistrc.

It will return an esbuild-compatible array of browsers.

import { build } from 'esbuild'
import browserslistToEsbuild from 'browserslist-to-esbuild'

await build({
  entryPoints: ['input.js'],
  outfile: 'output.js',
  bundle: true,
  target: browserslistToEsbuild(), // --> ["chrome79", "edge92", "firefox91", "safari13.1"]
})

Otherwise, you can pass yourself a browserslist string or array to the function.

browserslistToEsbuild('>0.2%, not dead')
