@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 (opens in a new tab) using SWC.

Installation

pnpm i -D jest @swc/core @swc/jest

Usage

Inside jest.config.js, configure Jest to use SWC:

module.exports = {
  transform: {
    "^.+\\.(t|j)sx?$": ["@swc/jest"],
  },
};
