esbuild-plugin-shelljs

Plugin for esbuild to be able to bundle shelljs. Without this fix, bundling shelljs gives error:

Error: Module not found in bundle: ./src/cat

Install

npm i -D esbuild-plugin-shelljs

import { shellJsPlugin } from "esbuild-plugin-shelljs";

esbuild.build({
  // [..]
  plugins: [shellJsPlugin],
});

How does it work

This plugin patches the shelljs dependency before bundling it. Esbuild knows the path of shelljs local dependencies with .js suffixes, but a dynamic import which omits the extension makes esbuild fail to resolve dependencies. The patch adds .js to the dynamic imports.
