`"$" is undefined ` errors when using JQuery

[ckib16]

Hey all - noob questions that I couldn't find an answer for.

1) I'm getting multiple "$" is undefined errors from the linter when entering standard JQuery code. Do I have to add $ to the "ignored list", or is there better integration with JQuery that I'm missing to avoid these errors?

2) I found out how to stop the errors in each file with /* global $ */. But how do I find the file package.json to ignore $ permanently? And is permanently ignoring $ a wise move?

Thanks, Chris

In your package.json, add $ to your globals array.

{
  "name": "Example",
  "version": "1.0.0",
  "description": "Example package.json",

  "standard": {
    "globals": [
      "$"
    ]
  }
}

@shaungrady is absolutely correct :smiley:

Thanks guys, much appreciated. I will investigate the whole package.json thing. Take care.

Hey all,

Quick follow up question - I'm still getting multiple '$' is undefined errors even after modifying my ~/.atom/packages/linter-js-standard/package.json file as described above.

Here is my package.json:

...
  "devDependencies": {
    "standard": "^5.2.1"
  },
  "standard": {
    "globals": [
      "atom",
      "$"
    ]
  },
  "package-deps": [
    "linter"
  ],
...

The atom line was already inside the globals array, so I didn't want to mess with it. I just added in "$" below it. I also tried:

• Quitting & restarting Atom
• Toggling the 4 setting available on the package settings page ("Check Style Dependencies", "Honor Style Settings", etc.)
• Adding /* global $ */ to each file. This still works as advertised, but very cumbersome!

Any ideas? Syntax error in my package.json file?

You shouldn't be modifying the package.json of the Atom package. You should adding/modifying rules in the package.json associated with whatever project you're working on. E.g., ~/My Repositories/my-project/package.json

Ah...

Ok, I'm trying to use it to lint JS inside of a Rails app, so I don't have a package.json. I'll have to experiment to see if there's a way to integrate it into Rails.

Any tips appreciated if someone has done this before. Thanks for the help,

package.json is for configuring npm, it doesn't directly relate to ESLint. For your Rails app, simply create a .eslintrc.js file at the root of your project. See the ESLint docs for more information: http://eslint.org/docs/user-guide/configuring#configuration-file-formats

Wow, thanks @shaungrady . I would never have found that. I'll take it from here, much appreciated!

No problem, happy coding

I'm having the same problem as @ckib16, and I'm not sure what to put into .eslintrc.js to make it work.
