vfile utility to create a report in machine readable JSON.

Contents

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 16+), install with npm:

npm install vfile-reporter-json

In Deno with esm.sh:

import {reporterJson} from 'https://esm.sh/vfile-reporter-json@4'

In browsers with esm.sh:

<script type="module">
  import {reporterJson} from 'https://esm.sh/vfile-reporter-json@4?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":[{"column":4,"fatal":false,"line":2,"place":{"line":2,"column":4},"reason":"Warning!"}]},{"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.

reporterJson(files[, options])

Create a serialized JSON report from one file or multiple files.

Parameters
Returns

Report as serialized JSON (string).

Reporters must return strings, which is why serialized JSON is exposed. You can parse the result with JSON.parse, in which case you will get Array<JsonFile>.

JsonFile

JSON file (TypeScript type).

Fields

JsonMessage

JSON message (TypeScript type).

Fields

Options

Configuration (TypeScript type).

Fields

Types

This package is fully typed with TypeScript. It exports the additional types JsonFile, JsonMessage, and Options.

Compatibility

Projects maintained by the unified collective are compatible with maintained versions of Node.js.

When we cut a new major release, we drop support for unmaintained versions of Node. This means we try to keep the current release line, vfile-reporter-json@^4, compatible with Node.js 16.
