dx-platform is a monorepo project.

After cloning, run yarn to fetch dependencies for all packages. Then, run yarn lerna run prepare to build all packages.

Also you can run several commands:

• yarn test — checks codestyle and run tests for all packages.
• yarn lerna run watch --parallel — runs watch task for each package in parallel. You can manage scope of packages using --scope [glob] flag (see lerna documentation for details)
