  • SurveyJS - Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App
  • InfluxDB - Power Real-Time Data Analytics at Scale
  • WorkOS - The modern identity platform for B2B SaaS
  • testdouble.js (AKA td.js)

    A minimal test double library for TDD with JavaScript

  • ESM modules need custom loaders for mocking. Testsouble (https://www.npmjs.com/package/testdouble) was one of the first frameworks to support it AFAIK and a great type-safe option.

  • vitest

    Next generation testing framework powered by Vite.

  • If it's not a huge codebase then I'd go for https://vitest.dev/, which is a modern take on testing frameworks.

  • SurveyJS

    Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App. With SurveyJS form UI libraries, you can build and style forms in a fully-integrated drag & drop form builder, render them in your JS app, and store form submission data in any backend, inc. PHP, ASP.NET Core, and Node.js.
