esbuild-plugin-browserslist

Configure esbuild's target based on a browserslist query

Installation

yarn add esbuild-plugin-browserslist esbuild browserslist

Usage

import esbuild from "esbuild";
import browserslist from "browserslist";
import {
  esbuildPluginBrowserslist,
  resolveToEsbuildTarget,
} from "esbuild-plugin-browserslist";

await esbuild.build({
  entryPoints: ["./foo/bar.ts"],
  // ... other options (except `target`) ...
  plugins: [
    esbuildPluginBrowserslist(browserslist("defaults"), {
      printUnknownTargets: false,
    }),
  ],
});

// Or:

const target = resolveToEsbuildTarget(browserslist("defaults"), {
  printUnknownTargets: false,
});

await esbuild.build({
  entryPoints: ["./foo/bar.ts"],
  target,
});

const esbuild = require("esbuild");
const browserslist = require("browserslist");
const {
  esbuildPluginBrowserslist,
  resolveToEsbuildTarget,
} = require("esbuild-plugin-browserslist");

Caveats

• Only edge, firefox, chrome, safari, ios_saf, and node have direct equivalents for esbuild targets.
• android and and_chr are mapped to the chrome target, and and_ff is mapped to the firefox target.
• All other browsers are ignored (and_qq, samsung, opera, op_mini, op_mob, ie, ie_mob, bb, baidu, and kaios)

Debugging

You can turn on debug logs (which will print all resolutions or failures) using DEBUG=esbuild-plugin-browserslist
