issue-parser

What is issue-parser?

The issue-parser npm package is designed to parse issue references from commit messages, pull requests, and other text. It helps in extracting and managing issue references in a structured way.

What are issue-parser's main functionalities?

Parsing Issue References

This feature allows you to parse issue references from a given text. In this example, the text 'Fixes #123' is parsed to extract the issue reference '#123'.

const issueParser = require('issue-parser')();
const result = issueParser('Fixes #123');
console.log(result);

Customizing Issue Patterns

This feature allows you to customize the patterns for issue references. In this example, the parser is configured to recognize 'gh-' as a valid issue prefix.

const issueParser = require('issue-parser')({
  issuePrefixes: ['#', 'gh-'],
  issueURLSegments: ['issues', 'pull']
});
const result = issueParser('Fixes gh-123');
console.log(result);

Parsing Multiple Issue References

This feature allows you to parse multiple issue references from a single text. In this example, the text 'Fixes #123, closes #456' is parsed to extract both issue references '#123' and '#456'.

const issueParser = require('issue-parser')();
const result = issueParser('Fixes #123, closes #456');
console.log(result);

Other packages similar to issue-parser

parse-commit-message

The parse-commit-message package is used to parse and validate commit messages according to the Conventional Commits specification. It provides a structured way to handle commit messages, similar to how issue-parser handles issue references.

commitlint

The commitlint package is used to lint commit messages based on predefined rules. It ensures that commit messages follow a specific format, which can include references to issues. While it doesn't parse issue references directly, it helps maintain a consistent format that can be parsed by tools like issue-parser.
