JSON-formatted output via `-f json`

[rstacruz]

Eslint supports this -f json to output JSON-formatted output:

./node_modules/.bin/eslint '**/*.js*' -f json | jq .

[
  {
    "filePath": "/Users/rsc/Projects/lol/behaviors/role-select.js",
    "messages": [
      {
        "ruleId": "no-multiple-empty-lines",
        "severity": 2,
        "message": "Too many blank lines at the end of file. Max of 0 allowed.",
        "line": 94,
        "column": 1,
        "nodeType": "Program",
        "source": "",
        "endLine": 95,
        "endColumn": 1,
        "fix": {
          "range": [
            2301,
            2302
          ],
          "text": ""
          /* snip */

Motivation

We can use tools that consume Eslint's JSON output, eg, https://github.com/rstacruz/stylelint-disable-all.

To be clear, @rstacruz is asking about optionally outputting JSON for the warnings emitted by standard (from eslint), for consumption by other tools.

Not that standard could add a JSON formatting feature.

I think?

Happy to help adding this to standard-engine if you welcome it :)

@rstacruz Have you tried using standard-json? It's a standalone tool that takes the output from standard and converts it to JSON.

standard --verbose | standard-json

ohh, i suppose thats what I'm looking for. It's not as verbose as eslint's -f json flag but it'll do for most cases.
