Just is a library that organizes build tasks for your JS projects. It consists of

  • a build task build definition library
  • sane preset build flows for node and browser projects featuring Typescript, Webpack and jest
  • project scaffold tool that generates no-ejection needed repos that tracks template changes


All the documentation is online at


This README contains only the instructions on how to build and contribute to the project. This is a monorepo that uses the rush monorepo management utility. To get started, simply run the following:

npm install

and build all the packages this way:

npm run build

Development is usually done one package at a time. So go into each package and develop with the innerloop npm script:

cd packages/just-task
npm run dev

Tests are run with the test npm script:

cd packages/just-task
npm test
