tslib-cli/config/jest.config.js

maximum overkill for typescript and javascript library authors

const path = require('path');

module.exports = {
	clearMocks: true,
	preset: 'ts-jest',
	rootDir: path.resolve(process.cwd()),
	testEnvironment: 'jsdom',
	coveragePathIgnorePatterns: ['/node_modules/', '/tests/', '/dist/'],
};
