Provides support for the Elm programming language.

Should work on IDEA (Community and Ultimate), WebStorm, PyCharm, RubyMine and more. If not please raise an issue.

The new release 5 is not yet uploaded to the IntelliJ Marketplace. To try it, manual download the latest 5.0.0-beta release as described below. Alternatively, download the sources and help fix things. Read how in our guide.

First make sure to uninstall all other Elm plugins you may have installed (this requires a restart of the IDE). Some have reported that having two Elm plugins installed results in the IDE not starting but showing a seemingly unreleated error (if you have this problem, there are ways to fix it).

From within a JetBrains IDE, go to Settings -> Plugins -> Marketplace and search for "Elm". After installing the plugin, restart the IDE and then open your existing Elm project or create a new project.

Alternatively you can install it manually by downloading a release (or downloading the source and building it yourself) and installing it with Settings -> Plugins -> ⚙️ (gear icon) -> Install plugin from disk...

NOTE: if you have node installed using nvm, make sure to read our NVM setup guide.
