CI/CD Pipeline

[mdp]

The zim file should be built and made available as a artifact for each push.

• Cache the npm modules (key: yarn.lock)
• Cache the main.zip from FCC so we don't waste time and bandwidth unnecesarily (key: yarn.lock)
• Run all the tests on 'client'

Done correctly, the build time should be <1 minute if cached, <3 minutes if not

Closing this. The workflow currently builds a zim file, but we need to determine the appropriate place to put that file, which is another task
