JSON errors in Syntastic

[mmwtsn]

Syntastic is showing errors from Standard in various valid JSON files. When the same files are checked using the standard executable no errors are returned.

For example, this repository's package.json file is returning the following:

{
  "name": "standard",
  // …
}
// package.json|2 col 9 warning| Unexpected token : (undefined)

With arrays, double quotes are flagged:

[
  "string"
]
// ./array.json|2 col 4 warning| Strings must use singlequote. (quotes)

Any ideas?

Got it. JSON files were being detected as JavaScript files.

If anyone comes across this you can check by opening a JSON file and running :set filetype?. The response should be filetype=json.
