# StrykerJS

*Professor X: For someone who hates mutants... you certainly keep some strange company.*

*William Stryker: Oh, they serve their purpose... as long as they can be controlled.*

Welcome to StrykerJS's monorepo. This is where all official stryker packages are maintained.

If you're new to monorepos: don't be scared. You'll find the packages in the `packages` folder.

If you're interested in why we chose a monorepo, please read [babeljs's design document about monorepos](https://github.com/babel/babel/blob/master/doc/design/monorepo.md). We use it for the same reasons as they do.

## Introduction

For an introduction to mutation testing and Stryker's features, see [stryker-mutator.io](https://stryker-mutator.io/).

## Getting started

Please follow the [quickstart on the website](https://stryker-mutator.io/docs/stryker-js/getting-started/).

For small js projects, you can try the following command:

```

npm install --save-dev @stryker-mutator/core

# Only for small projects:

npx stryker run

```

It will run stryker with default values:

* Uses `npm test` as your test command

* Searches for files to mutate in the `lib` and `src` directories

## Usage

```sh

$ npx stryker  [options] [configFile]

```

See [usage on stryker-mutator.io](https://stryker-mutator.io/docs/stryker-js/usage)

## Supported mutators

See our website for the [list of currently supported mutators](https://stryker-mutator.io/docs/mutation-testing-elements/supported-mutators).

## Configuration

See [configuration on stryker-mutator.io](https://stryker-mutator.io/docs/stryker-js/configuration).
