What is this?

This package is like vfile-reporter but it outputs machine readable JSON.

When should I use this?

You can use this when you need to serialize lint results for machines, use vfile-reporter itself for humans.

Install

This package is ESM only. In Node.js (version 12.20+, 14.14+, or 16.0+), install with npm:

npm install vfile-reporter-json

In Deno with esm.sh:

import {reporterJson} from 'https://esm.sh/vfile-reporter-json@3'

In browsers with esm.sh:

<script type="module">
  import {reporterJson} from 'https://esm.sh/vfile-reporter-json@3?bundle'
</script>

Use

import {VFile} from 'vfile'
import {reporterJson} from 'vfile-reporter-json'

const one = new VFile({path: 'test/fixture/1.js'})
const two = new VFile({path: 'test/fixture/2.js'})

one.message('Warning!', {line: 2, column: 4})

console.log(reporterJson([one, two]))

Yields:

[{"path":"test/fixture/1.js","cwd":"/Users/tilde/projects/oss/vfile-reporter-json","history":["test/fixture/1.js"],"messages":[{"reason":"Warning!","line":2,"column":4,"position":{"start":{"line":2,"column":4},"end":{"line":null,"column":null}},"ruleId":null,"source":null,"fatal":false,"stack":null}]},{"path":"test/fixture/2.js","cwd":"/Users/tilde/projects/oss/vfile-reporter-json","history":["test/fixture/2.js"],"messages":[]}]

API

This package exports the identifier reporterJson. That identifier is also the default export.

reporter(files[, options])

Generate stringified JSON for files (VFile or Array.<VFile>).

options.quiet

Do not output anything for a file which has no warnings or errors (boolean, default: false). The default behavior is to show a success message.

options.silent

Do not output messages without fatal set to true (boolean, default: false). Also sets quiet to true.

options.pretty

Given as space to JSON.stringify() (boolean, number, or string, default: 0). When true, defaults to 2.

Types

This package is fully typed with TypeScript. It exports the additional type Options.

Compatibility

Projects maintained by the unified collective are compatible with all maintained versions of Node.js. As of now, that is Node.js 12.20+, 14.14+, 16.0+, and 18.0+. Our projects sometimes work with older versions, but this is not guaranteed.
