Frequently Asked Questions

What does ts-jest do?

Ts-jest is a Jest transformer that comes with source map support, allowing Jest tests to be run on projects written in TypeScript. Along with support for all TypeScript features, the package provides type-checking capabilities - an essential feature for any TypeScript code handling library or tool.

How do you use ts-jest?

To start using ts-jest in your project, first ensure that both Jest and TypeScript are installed. You can accomplish this by running npm i -D jest typescript if you use npm or yarn add --dev jest typescript if you prefer yarn. Next, install ts-jest and @types/jest by running npm i -D ts-jest @types/jest on npm or yarn add --dev ts-jest @types/jest on yarn.

After the necessary installations are complete, you can set up the configuration for ts-jest by running the command npx ts-jest config:init for npm or yarn ts-jest config:init for yarn. Finally, you can execute your tests by running npm test or npx jest on npm and yarn test or yarn jest on yarn.

Where are the ts-jest docs?

The official documentation for ts-jest, including specific usage instructions, technical details, and more, can be found at https://kulshekhar.github.io/ts-jest. The accompanying README file available in the GitHub repository at https://github.com/kulshekhar/ts-jest also provides helpful information about the package.
