Pull Lock

Automate tasks that happen when you pull in new code.

{
  "husky": {
    "hooks": {
      "post-merge": "pull-lock"
    }
  },
  "pull-lock": {
    "yarn.lock": "yarn install",
    "Example/Podfile.lock": ["cd Example", "bundle exec pod install"]
  }
}

Like lint-staged for when you've git pulled. You set up a husky "post-merge" hook which runs the CLI tool pull-lock.

pull-lock will then compare the changed files to the config and execute commands for you automatically.

Pull Lock only uses dependencies which Husky also uses, and so it adds no new dependencies to your tree.

Installation and setup

1. yarn add --dev pull-lock husky
2. Update your package.json like this:

{
  "husky": {
    "hooks": {
+     "post-merge": "pull-lock"
    }
  },
+ "pull-lock": {
+   "yarn.lock": "yarn install",
+ }
}

Then when you run a git pull or git merge, pull-lock will check to see if yarn.lock has changed the diffed files and run the scripts inside your config files.

In the case above, if someone has made dependency changes which edit the yarn.lock then yarn install will be called automatically for you.

Advanced config

As pull-lock uses cosmic-config you can leave your app settings in either:

• a pull-lock object in your package.json

• a .pulllockrc file in JSON or YML format

• a pull-lock.config.js file in JS format
