push-deploy

A simple script that allows us to deploy by catching up a branch (e.g. production) to the main branch and then pushing that branch.

Does several sanity checks to help prevent errors, increments version and tags the deploy

Usage

Add a script to package.json of the project like:

{
  "scripts": {
    "deploy:production": "push-deploy main production"
  }
}

If you need to update environment variables, do that before calling the script. In this example, we presume there is a script named set-env:production which sets the environment variables on the production servers.

{
  "scripts": {
    "deploy:production": "yarn set-env:production && push-deploy main production"
  }
}

Sanity Checking

It does a few things that help make life easier:

• Make sure that the current git status is clean
• Make sure that we are starting in the correct branch. If we are deploying from main to production but we are currently not on main, we will show an error.
• Make sure that there aren't any commits in the target branch that don't existin the source branch. In other words, we want this to be a fast forward deploy only.

Version Management

• Increases version of src and target to next version
• Pushes it for safekeeping
• Also pushes tags for safekeeping
