JavaScript code intelligence for atom with Tern. Adds support for ES5, ES6, ES7, Node.js, jQuery, Angular and more. Extendable via plugins. Uses suggestion provider by autocomplete-plus.


Configure your project

  • Open any JavaScript file from within your project
  • Navigate to Packages -> Atom Ternjs -> Configure project
  • The config view appears.
  • Hit Save & Restart Server to create/update the .tern-project file


  • install the package

If configure project does not work

  • In your project root create a file named .tern-project. See docs @
  • Restart the server via Packages -> Atom Ternjs -> Restart server

Example .tern-project file (customize to your own needs):

  "ecmaVersion": 6,
  "libs": [
  "loadEagerly": [
  "dontLoad": [
  "plugins": {
    "es_modules": {},
    "node": {},
    "doc_comment": {
      "fullDocs": true,
      "strong": true

In order to use third party plugins read the Third party plugins section!

In order to use third party plugins from within your project's node_modules read the Third party plugins local section! This is also an alternative if Third party plugins aren't working.


  • 5: use ECMAScript5
  • 6: use ECMAScript6 (default)
  • 7: use ECMAScript7


  • browser: completion for vanilla js (optional)
  • jquery: completion for jQuery (optional)
  • underscore: completion for underscore (optional)
  • chai: completion for chai (optional)


  • loadEagerly: provide the path to your projects js. For relative paths do not use ./ as a prefix. This sometimes leads to an unexpected behaviour.
  • loadEagerly is expensive. Do not add paths like node_modules.
  • dontLoad: can be used to prevent Tern from loading certain files. It also takes an array of file names or glob patterns.


  • For a list of build in server plugins, visit:


List of keybindings. To use your own keybindings goto atom-ternjs package settings and disable keybindings.

Third party plugins

In order to use third party plugins (e.g. tern-node-express):

$ cd ~/.atom/packages/atom-ternjs
$ npm install tern-node-express

Add the plugin to your .tern-project file:

  "ecmaVersion": 6,
  "libs": [
  "loadEagerly": [
  "plugins": {
    "node-express": {}

Third party plugins are still an issue and sometimes do not work as expected, especially if the plugin requires a tern version that does not match the tern version that is used by atom-ternjs.

Restart the server: Packages -> Atom Ternjs -> Restart server

Third party plugins local

Example for node-express. Open node_modules/tern-node-express/tern-express.js


(function(mod) {
  if (typeof exports == "object" && typeof module == "object") // CommonJS
    return mod(require("tern/lib/infer"), require("tern/lib/tern"));
  if (typeof define == "function" && define.amd) // AMD
    return define([ "tern/lib/infer", "tern/lib/tern" ], mod);
  mod(tern, tern);


(function(mod) {
  return mod(process.__infer, process.__tern);

Restart Atom.

.tern-project created/modified

  • After the file was created or has been modified, restart the server via Packages -> Atom Ternjs -> Restart server


  • Completion (autocompletion triggers automatically), or via the keybindings:
    • ctrl+space
    • ctrl+alt+space (force autocompletion in any context)



  • Find references (set your cursor position to one of variable, function or instance -> open context-menu and trigger Find references or use the keybindings:
    • ctrl+shift+r (macOS, Windows)
    • ctrl+alt+shift+e (Linux)

Click any item in the generated reference-list and navigate directly to file and position


  • Documentation

    • Show documentation for the thing under the cursor via alt+o (macOS, Windows, Linux) atom-ternjs
    • Also displayed if a suggestion with a valid documentation is selected in the autocomplete-plus select-list
  • Find definition (set your cursor position to one of variable, function or instance -> open context-menu and trigger Find definition) or use the keybindings:

    • cmd+click (macOS, Windows, Linux), requires Since cmd+click is also used for multi-line editing in macOS you should change the default hyperclick settings.
    • ctrl+alt+shift+d (macOS, Windows, Linux)
  • Navigate back or forward

    • ctrl+shift+cmd+left (macOS, Windows, Linux)
    • ctrl+shift+cmd+right (macOS, Windows, Linux)
  • Rename variable (set your cursor position to a variable -> open context-menu and trigger Rename) or use the keybindings:

    • ctrl+alt+c (macOS, Windows)
    • ctrl+alt+shift+c (Linux)
