@swc/jest
To make your Jest tests run faster, you can swap out the default JavaScript-based runner (ts-jest) for a drop-in Rust replacement using SWC.
Installation
# if you use npm
npm i -D jest @swc/core @swc/jest
# if you use yarn
yarn add -D jest @swc/core @swc/jestUsage
Inside jest.config.js, configure Jest to use SWC:
module.exports = {
transform: {
"^.+\\.(t|j)sx?$": ["@swc/jest"],
},
};
