@dry-lint/dry-lint

The core engine and registry for dry-lint. Provides the singleton extractor registry, structural similarity algorithms, and ts-morph project — powering all official plugins and the CLI.

Install

You usually don’t install @dry-lint/dry-lint directly. It’s included automatically when you install the CLI or any official plugins.

Example:

# Example: TypeScript + Zod plugins + CLI
bun add -D @dry-lint/cli @dry-lint/typescript @dry-lint/zod

The CLI depends on @dry-lint/dry-lint under the hood.

How it works

@dry-lint/dry-lint exposes the core APIs:

import { registerExtractor, findDuplicates } from '@dry-lint/dry-lint';

registerExtractor((filePath, fileText) => {
  // Return an array of declarations for this file
  return [];
});

const groups = await findDuplicates(['src/**/*.ts'], { threshold: 0.9 });

Plugins use registerExtractor to plug in domain-specific parsers. The CLI and custom Node scripts use findDuplicates to orchestrate extraction, grouping, and output.

What replaced @dry-lint/core?

• The old @dry-lint/core is fully merged into this package.
• One singleton registry, one ts-morph project, no duplicate states.
• All plugins and the CLI now share the same stable core.

If you see any instructions to install @dry-lint/core, just use @dry-lint/dry-lint instead.
