Running ImportJS in Emacs

1. Install the importjs binary:

• npm install import-js -g

2. Configure ImportJS

• See Configuration

3. Install import-js.el for Emacs

• Install via MELPA
• Alternatively, Copy plugins/import-js.el into your Emacs load-path and add (require 'import-js) to your config. You will also need to install grizzl

4. Run the import-js daemon

• (M-x) run-import-js
• The daemon will use watchman if installed to improve performance

5. Import a file!

• You can use something like (M-x) import-js-import with your cursor over the desired module

• It will be helpful to bind import-js-import to an easy-to-use binding, such as:

  (define-prefix-command 'my-keymap)
  (global-set-key (kbd "s-a") 'my-keymap)
  (define-key my-keymap (kbd "a u") 'import-js-import)
  

6. Go directly to a file

• The ImportJS goto interface allows us to jump to a package
• (M-x) import-js-goto will jump to the appropriate file found by ImportJS
• This should also be bound to something useful: (global-set-key (kbd "<f4>") 'import-js-goto)

7. Fix your imports

• Optionally, you can configure ImportJS to fix your imports for you, adding unknown variables and removing unused imports. ImportJS uses eslint to find these variables.
• eslint must be in your PATH.
• eslint plugins must be installed for that specific version of eslint (if eslint is a global eslint, you may need to install the plugins globally)
• Run with (M-x) import-js-fix
• You can also configure import-js-fix to run on save: (add-hook 'after-save-hook 'import-js-fix)

Note on Node v6.1.0

I've had issues running import-js in Emacs on Node v6.1.0. Node >= v6.2.0 seems to work as expected.
