**`ts-jest`** is a TypeScript preprocessor with source map support for Jest that lets you use Jest to test projects written in TypeScript.
|
||
|
|
|
||
|
|
It supports all features of TypeScript including type-checking. [Read more about Babel7 + `preset-typescript` **vs** TypeScript (and `ts-jest`)](https://kulshekhar.github.io/ts-jest/user/babel7-or-ts).

| We are not doing semantic versioning and `23.10` is a re-write, run `npm i -D ts-jest@"<23.10.0"` to go back to the previous version |

## Versioning
|
||
|
|
|
||
|
|
We **DO NOT** use [SemVer](http://semver.org/) for versioning. Though you can think about SemVer when reading our version, except our major number follows the one of Jest. For the versions available, see the [tags on this repository](https://github.com/kulshekhar/ts-jest/tags).
