Indium

A JavaScript development environment for Emacs.

Indium connects to a browser tab or nodejs process and provides many 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.

Documentation

Installation instruction and other documentation can be found on readthedocs.

WARNING: Indium 2.0 now uses a client/server architecture, see installation instuctions.

Missing features

Indium is young, here's a list of missing/wanted features

• Code evaluation using C-x C-e from project JS buffers
• Adding breakpoints (to remove the need for debugger statements)
• Network inspector (could get inspiration from restclient.el)
• DOM inspector
• Start processes (chromium, node, grunt, gulp, etc.) from Emacs and attach a indium connection to it.

Backends

There is currently support for Chrom[e|ium] & nodejs. The firefox backend is in the TODO list.
