Dynamic Configuration

TypeScript

Instead of a JSON file, you can use a JavaScript or TypeScript file for a dynamic configuration and type annotations:

TypeScript

knip.ts

import type { KnipConfig } from 'knip';

const config: KnipConfig = {
  entry: ['src/index.ts'],
  project: ['src/**/*.ts'],
};

export default config;

JavaScript

knip.js

/** @type {import('knip').KnipConfig} */
const config = {
  entry: ['src/index.ts'],
  project: ['src/**/*.ts'],
};

export default config;

Function

You can export a regular or async function that returns the configuration object as well:

TypeScript

knip.ts

import type { KnipConfig } from 'knip';

const config = async (): Promise<KnipConfig> => {
  const items = await fetchRepoInfo();

  return {
    entry: ['src/index.ts', ...items],
    project: ['src/**/*.ts'],
  };
};

export default config;

JavaScript

knip.js

const config = async () => ({
  entry: ['src/index.ts'],
  project: ['src/**/*.ts'],
});

export default config;
