Indium

Indium is a JavaScript development environment for Emacs.

Indium is Free Software, licensed under the GPL v3.0. You can follow its development on GitHub.

Indium connects to a browser tab or nodejs process and provides several features for JavaScript development, including:

• a REPL (with auto completion) & object inspection;
• an inspector, with history and navigation;
• a scratch buffer (M-x indium-scratch);
• JavaScript evaluation in JS buffers with indium-interaction-mode;
• a stepping Debugger, similar to edebug, or cider.

This documentation can be read online at https://indium.readthedocs.io.

It is also available in Info format and can be consulted from within Emacs with C-h i m indium RET.
