What does it take to support Node.js ESM?

• plugins

  9 2,291 8.8 JavaScript

  🍣 The one-stop shop for official Rollup plugins (by rollup)

  

  The only workaround to have an isomorphic __dirname or __filename to be used for both "cjs" and "esm" without using build-time tools like @rollup/plugin-replace or esbuild "define" would be using a library like filedirname that does a trick inspecting error stacks, it's clearly not the cleanest solution.

• TypeScript

  454 77,335 9.9 TypeScript

  TypeScript is a superset of JavaScript that compiles to clean JavaScript output.

  

  Until this issue TypeScript#33069 is closed, TypeScript doesn't have complete support for it, fortunately, there are 2 workarounds:

• Scout APM

  Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.

• tsup

  6 1,326 9.2 TypeScript

  The simplest and fastest way to bundle your TypeScript libraries.

  The best solution for this is to have ESM examples in a monorepo testing firsthand if everything with the logic included doesn't break, using tools that output both CommonJS & ESM like tsup might become very handy, but that might not be straightforward, especially for big projects.

• ts-jest

  8 5,442 9.7 TypeScript

  A Jest transformer with source map support that lets you use Jest to test projects written in TypeScript.

  There are workarounds, but nothing actually works in 100% of the possible use-cases (see for example, ts-jest issue), and for that reason, we recommend tooling that enables this type of building without needing any workaround, usually using Rollup and/or esbuild.
