Developer tools

If you are using VSCode with Ember CLI, there's an official extension pack maintained by the Ember Learning team that adds multiple Ember plugins that can help in Ember development. If you already have VSCode installed on your machine, you can click here to view this extension pack inside VSCode. Alternatively, you can also search for embertooling.emberjs inside the extensions view.

If you are using Atom with Ember CLI, there are some packages available specific to Ember development.

Atom -> Preferences -> Install

• ide-ember - Ember Language Server support in Atom
• ember-cli-helper - Ember CLI integration in Atom
• ember-tabs - Makes atom.io work better with Ember pods
• atom-ember-components - See all controllers and components that are rendering your component. Currently only works with pods structure.
• atom-ember-snippets - Autocomplete for Ember module imports, component, service and route skeletons, and more.

If you are using Emacs with Ember CLI, Emacs creates temporary backup, autosave, and lockfiles that interfere with broccoli watcher, so they need to either be moved out of the way or disabled. To do that, ensure your emacs configuration contains the following:

(setq backup-directory-alist `((".*" . ,temporary-file-directory)))
(setq auto-save-file-name-transforms `((".*" ,temporary-file-directory t)))
(setq create-lockfiles nil)

An ember-mode package is also available. It has shortcuts for quickly navigating files in Ember projects, running generators, and running build, serve, and test tasks. It also includes support for linking build errors to files and minibuffer notifications of ember serve status. It can be installed from MELPA. To use MELPA, ensure your configuration contains the following:

(require 'package)
(add-to-list 'package-archives
             '("melpa" . "http://melpa.org/packages/") t)
(package-initialize)

Then ember-mode can be installed from the package menu at M-x package-list-packages. After it is installed, add a file named .dir-locals.el to the root of your Ember projects with the contents:

((nil . ((mode . ember))))

to enable it inside those projects.

If you are using Sublime Text with Ember CLI, by default it will try to index all files in your tmp directory for its GoToAnything functionality. This will cause your computer to come to a screeching halt @ 90%+ CPU usage, and can significantly increase build times. Remove these directories from the folders Sublime Text watches:

Sublime Text -> Preferences -> Settings - User

// folder_exclude_patterns and file_exclude_patterns control which files
// are listed in folders on the side bar. These can also be set on a per-
// project basis.
"folder_exclude_patterns": [".svn", ".git", ".hg", "CVS", "tmp/class-*", "tmp/es_*", "tmp/jshinter*", "tmp/replace_*", "tmp/static_compiler*", "tmp/template_compiler*", "tmp/tree_merger*", "tmp/coffee_script*", "tmp/concat-tmp*", "tmp/export_tree*", "tmp/sass_compiler*"]

If you are using WebStorm with Ember CLI, you will need to modify your .gitignore file, enable ECMAScript6 settings, and mark certain directories.

First, add the following line to .gitignore:

.idea

Next, from the WebStorm menu:

File > Settings -> Languages & Frameworks -> JavaScript -> ECMAScript6

Click 'OK' to close the Settings modal window.

Next, in Webstorm's Project window right-click on each of the following directories, go to 'Mark Directory As' and mark as indicated:

Mark as Excluded:

/tmp
/dist

Mark as Resource Root:

/
/public

Mark as Test Sources Root:

/tests

This plugin provides excellent Ember.js support for all JetBrains IDEs that support JavaScript, including WebStorm.

In order to install it, go to:

File | Settings... | Plugins | Browse repositories...

Search for Ember.js and click the Install button.

If you are using Vim with Ember CLI, Vim creates temporary backups and autosaves which interfere with broccoli, so they need to either be moved out of the way or disabled.

By default, Vim places the temporary backup and autosave files right next to the associated file. If you change where Vim puts these backup and autosave files, you can still get the benefits of these features without it interfering with Ember.js or your build.

In your .vimrc, add:

set backupdir=~/.vim/backup//
set directory=~/.vim/swap//
set undodir=~/.vim/undo//

And make sure to create the directories:

mkdir -p ~/.vim/backup; mkdir -p ~/.vim/swap; mkdir -p ~/.vim/undo

If you'd like to disable backups, you could add to your .vimrc:

set nobackup
set noswap
set noundofile

Some useful Vim plugins for working with Ember.js:

• ember_tools - Provides various tools for navigation and code reformatting, similar to rails.vim for Rails.
• projectionist - Powerful project navigation, provided you write your own code projections. Here's an example

See the Debugging guide for tips on debugging build steps, addons, and custom blueprints.

When using ember serve, by default all network requests will target the Ember server at localhost:4200. You can use the --proxy flag to direct network requests to another address. For example

ember server --proxy=http://localhost:8080

will proxy network requests to the server running at http://localhost:8080. The localhost:8080 address can be replaced with the IP address of any remote server.
