esbuild-cf-functions-plugin

This plugin configures ESBuild for building code compatible with CloudFront Functions.

As can be seen in the documentation, CloudFront Functions do not run on Node, but on AWS's custom JS runtime.

According to them, it

... is compliant with ECMAScript (ES) version 5.1 and also supports some features of ES versions 6 through 9.

This plugin does its best to enable and disable transpiling features as the documentation says is available.

Usage

Installation

npm i -D esbuild-cf-functions-plugin

pnpm i -D esbuild-cf-functions-plugin

yarn add -D esbuild-cf-functions-plugin

// build.mjs
import { build } from "esbuild"
import { CloudFrontFunctionsPlugin } from "esbuild-cf-functions-plugin"

void build({
  entryPoints: ["src/index.ts"],
  outdir: "dist",

  minify: true,
  logLevel: "info",

  plugins: [CloudFrontFunctionsPlugin()],
})

The plugin overrides the format and target options, unless I did something wrong.

Todo:

• Check if destructing works
• Check if ESM works
