Adds a monorepo structure

[kettanaito]

Adopts a monorepo pattern for the repository that splits Atomic Layout into the core and rendering parts. This is a crucial pre-requisite for this library to become styling- and rendering-agnostic.

Changes

• Sets up a monorepo structure of the project
• Provides necessary dependencies adjustments to fit the monorepo
• Splits the library into two modules: atomic-layout-core and atomic-layout
• Adjusts CI to properly bootstrap, build and test all monorepo packages

GitHub

• Pre-requisite for [RFC] Pluggable styling API #57, React dependency #245

Release version

Although the scope of these changes may be big, there must be no breaking changes to the consumers of the library. Public API and package name (atomic-layout) shall remain as-is.

• patch (internal improvements)
• minor (backward-compatible changes)
• major (breaking, backward-incompatible changes)

Contributor's checklist

• My branch is up-to-date with the latest master
• I ran yarn ci and verified the build and tests passing

Roadmap

• Verify tests run in @atomic-layout/core
• Make atomic-layout depend on @atomic-layout/core
• Verify tests run in @atomic-layout/core
• Verify tests run in atomic-layout
• Buildatomic-layout
• Verify E2E tests in atomic-layout
• Adjust CircleCI
• Think through the order of jobs execution in the CI to make dependencies properly dependent
• Name CI jobs
• Adjust pre-commit commands
• Adjust bundlesize check
• Abstract generateComponents from parseTemplate composition
• Verify that working with the Layout instance is as intended
• Configure linting as a part of the CI
• Disable treating @atomic-layout/core as an external dependency during UMD/ESM build (needs to throw if it's not present)
• Reverted version bump to be properly included with tags via lerna publish
• Update Contributing guidelines in case yarn ci command is removed

The last E2E job can take a snapshot of the file system and pack it into an archive. Restoring the archive on local may be a good way to debug the failing state.

Update

It's useful to run a failing job with SSH and browse the remote machine's state from your local:

$ ssh -P <CIRCLECI_PORT> <CIRCLECI_HOST>

Entire SSH command is included in CircleCI once a job is run with SSH.

It's also possible to archive and copy files from the remote machine to inspect its state:

$ scp -i ~/.ssh/your_ssh_key -P <CIRCLECI_PORT> -r <USERNAME>@<CIRCLECI_HOST>:/root/<PWD> <COPY_DIST>

Resolved

The failing E2E job has been fixed by updating a Cypress docker container to include Chrome 78.
