Indium is a JavaScript development environment for Emacs that connects to a Chrome/Chromium browser tab or a Node.js process. It provides a REPL with completion, an object inspector, a stepping debugger, and in-buffer JavaScript evaluation.

Use cases

• debug javascript from emacs
• run a nodejs repl inside emacs
• inspect javascript objects in emacs
• step through javascript code like edebug
• evaluate javascript in the current buffer
• connect emacs to a chrome tab for development

When to choose

• you develop JavaScript in Emacs and want an IDE-like REPL and debugger
• you prefer Emacs tooling over browser DevTools for Node.js or Chrome debugging
• you want a cider-like experience for JavaScript

When to avoid

• you use VS Code or another editor with built-in JS debugging
• you need a Firefox backend or DOM/network inspector
• you want a project with frequent updates and active maintenance
