Package description

What is jest-config?

The jest-config package is used for configuring Jest, a popular JavaScript testing framework. It allows developers to programmatically access and manipulate Jest's configuration settings, making it easier to set up and customize tests for JavaScript projects. This package is particularly useful for complex setups or when integrating Jest into larger, automated workflows.

What are jest-config's main functionalities?

Accessing Default Configuration

This feature allows developers to access Jest's default configuration settings. It's useful for understanding the baseline configuration and for extending or customizing these defaults in a project.

const { defaults } = require('jest-config');
console.log(defaults);

Generating a Custom Configuration

This feature enables the creation of a custom Jest configuration programmatically. It's particularly useful for dynamically generating configurations based on specific project requirements or environments.

const { makeConfig } = require('jest-config');
const customConfig = makeConfig({
  rootDir: process.cwd(),
  transform: {
    '^.+\\.js$': 'babel-jest'
  }
});
console.log(customConfig);
