Build and Publish.yml

name: "Build and Publish"

# Simple automated publishing for projects

# Automatically publishes beta releases, when a change is pushed to a beta branch
# For a latest/production release, workflow must be manually kicked off / started from `Actions --> Build and Publish`.  ( This is by design to prevent accidental production releases.)
# Latest release includes a github release

# Release Workflow ( Beta --> Production )

# 1 - Determine what the target version will be for the final release and update the package.json version number ( ie `0.5.6`)
# 2 - Create a new branch including the target release version ie `beta-0.5.6`
# 3 - Commit the updated package.json to the new beta branch.  This will trigger a npm release with the beta tag, and npm version set to `0.5.6-beta.0`.
# 4 - As updates are made to the beta branch, npm beta releases will be created.
# 5 - Once the release is complete, and ready for latest/production release, create a pull request to merge the changes into the `latest` branch.
# 6 - After reviews are complete, merge the pull request
# 7 - For the latest/production release, the workflow must be manually kicked off / started from Actions --> Build and Publish
# 8 - Delete beta branch
