Stryker

NOTE: You're currently looking at the epic/mutation-switching branch, where we're currently working on implementing mutation switching. Please see the master branch for the current production version. We have a feature freeze until mutation switching is implemented.

Stryker

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 Stryker'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. We use it for the same reasons as they do.
