eslint-config-jxa

An ESLint Shareable Config to extend ESLint’s awesome linting powers to macOS JavaScript for Automation (JXA) code.

Installation

You'll need to install ESLint first, e.g.:

$ npm install eslint --save-dev

Next, install eslint-config-jxa, e.g.:

$ npm install eslint-config-jxa --save-dev

Usage

Add the relevant configuration to your extends section.

Basic configuration

If you use standard JavaScript file extensions (i.e. .js) for your JXA source code, all you have to do is to add this to your .eslintrc.json file`:

{
  "extends": [
    "jxa"
  ]
}

If you use the .jxa file extension, extend in an override instead:

{
  "overrides": [
    {
      "files": ["*.jxa"],
      "extends": ["jxa"]
    }
  ]
}

Additional configuration

There are additional configs available for some special JXA coding scenarios:

• objc: for JXA source that uses the Objective C bridge.
• library: for JXA files intended to be loaded via Library().
• injection: for JXA files intended as JXA Infusion injections.

Note these will only work in conjunction with the basic configuration. Because the additional configurations restrict the scope of, or, in the case of the objc rules, entirely disable some ESLint checks, you should only include them in very specific overrides, e.g. (example taken from the JXA Infusion project):

"overrides": [
  {
    "files": ["*.jxa"],
    "extends": ["jxa"]
  },
  {
    "files": ["Injections/**/*.jxa"],
    "extends": [
      "jxa/objc",
      "jxa/injection"
    ]
  },
  {
    "files": ["Libraries/**/*.jxa"],
    "extends": [
      "jxa/objc",
      "jxa/library"
    ]
  }
]
