JavaScript Standard Style does not recognize Mocha

I prefer to edit my .eslintrc and add mocha to env section:

...
"env": {
  "commonjs": true,
  "node": true,
  "mocha": true
},
...

this way my package.json file is kept clean, also vscode plugin for eslint understands it better

while eslint's comment configuration works great for a single file, I prefer to use standard's package.json globals configuration to do this for my projects. E.g.

{
  "name": "my-package",
  "version": "1.0.0",
  "standard": {
    "globals": [
      "describe",
      "context",
      "before",
      "beforeEach",
      "after",
      "afterEach",
      "it",
      "expect"
    ]
  }
}

Actually, you don't need to list every single global variable in your package.json

You can specify environments instead like this:

"standard": {
  "env": [ "mocha" ]
}
