What is this?
This package create a textual report from a file showing the warnings that occurred while processing. Many CLIs of tools that process files, whether linters (such as ESLint) or bundlers (such as esbuild), have similar functionality.
When should I use this?
You can use this package whenever you want to display a report about what occurred while processing to a human.
There are other reporters that display information differently listed in vfile.
Install
This package is ESM only. In Node.js (version 14.14+ and 16.0+), install with npm:
npm install vfile-reporter
In Deno with esm.sh:
import {reporter} from 'https://esm.sh/vfile-reporter@7'
In browsers with esm.sh:
<script type="module">
import {reporter} from 'https://esm.sh/vfile-reporter@7?bundle'
</script>
Use
Say our module example.js looks as follows:
import {VFile} from 'vfile'
import {reporter} from 'vfile-reporter'
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.error(reporter([one, two]))
…now running node example.js yields:
test/fixture/1.js
2:4 warning Warning!
test/fixture/2.js: no issues found
⚠ 1 warning

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

Upstream issues and maintenance review
Upstream and maintenance review
This package maintains vfile-reporter@7.0.5 under the independent @stackline/vfile-reporter name.
- Source: https://github.com/vfile/vfile-reporter/tree/36b98284e20615e9aaa862be10d105175cfa64bb
- Public npm artifact integrity:
sha512-NdWWXkv6gcd7AZMvDomlQbK3MqFWL1RlGzMn++/O2TI+68+nqxCPTvLugdOtfSzXmjh+xUyhp07HhlrbJjT+mw==. - Upstream issue evidence checked: 2026-09-29T00:22:19.543688+00:00.
- Original license and author notices are retained.
- The upstream published runtime files and declarations are hash-checked in
.stackline/upstream.json. Any runtime fix is explicitly listed there. - Functional upstream suites run against the source and extracted final package. Development tools were reduced to those used by validation; full source and runtime audits must pass.
- Only direct dependencies of the original Stackline portfolio are in this migration. This is not a claim that all transitive projects are maintained by Stackline.
Issue triage
The queried open-issue list contained no issue entries. This does not establish that the upstream is abandoned or bug-free. No runtime bug fix is claimed for this initial maintenance release.
The evidence query fetched the latest 100 open and 30 closed issue/PR entries and removed PRs. Closed entries were collected for context; this report does not claim an exhaustive historic review.
Release discipline
The source commit, passing CI and CodeQL, reviewed CI tarball hash, npm provenance, normal and aliased installs, and immutable GitHub release are checked before a release is complete. Published versions and tags are never replaced.
Release changes

Release files and references
Package bytes, npm provenance and the immutable GitHub release were verified for this version. Security checks describe the reviewed release; documented compatibility risks and upstream reports are not blanket claims of resolution.
