github-actions-linter v2.7.0

GitHubActions.js

Provides linting APIs on the command line, through Node.js, and rich code editing through VSCode.

Using the NPM Package

https://www.npmjs.com/package/github-actions-linter

Add the package through npm/yarn:

$ npm i github-actions-linter
$ yarn add github-actions-linter

Run linter through Node.js:

import { lint } from "github-actions-linter";

const diagnostics = lint(code);
console.log(diagnostics.length + " errors were found.");

diagnostics.forEach(diagnostic => {
  console.log(diagnostic.message);
});

Or invoke through the CLI:

$ github-actions-linter file1.workflow file2.workflow

It will exit cleanly if no errors were found, or with a positive error code (number of errors) if any existed:
