jest-config 29.7.0

Jest-config is a useful component in the Jest testing framework. It provides users with the ability to configure various testing parameters in Jest. With jest-config, developers can fine-tune every detail of their testing environment - from determining which types of files get compiled, to modifying the way the results are output. Acting as the brain of your Jest operations, jest-config handles all your project's testing configuration needs.

To use jest-config in your project, start by installing it via npm or Yarn. It's as easy as running the following command in your terminal:

npm install jest-config

or

yarn add jest-config

Once installed, you can import the package into your test files to make use of its functionality:

const {defaults} = require('jest-config');
console.log(defaults);  // Will log out default values of Jest configuration.

You can now use the imported defaults object to modify the configuration settings according to your project needs. Remember to export the modified configuration so it can be used by Jest.

module.exports = {
  ...defaults,
  // Overwrite any settings here by specifying new values
  
  // For example:
  testEnvironment: 'node',
};

The jest-config documentation is not found in a separate standalone resource. You'll find jest-config detailed in the comprehensive Jest API documentation. For a thorough walk-through of jest-config and how to make the most of it, visit the Jest documentation over at https://jestjs.io/docs/configuration. You'll find specific usage examples, default settings, and other important points on the page dedicated to Jest's configuration.
