@auto/start v0.0.4

auto

Set of helpers for managing and developing (mono)repos.

Overview

Let's say that there is the following monorepo structure using Yarn workspaces:

packages/
├── foo/
├── bar/
└── baz/

{
  "name": "@scope/foo",
  "version": "0.1.0",
  "dependencies": {
    "@scope/bar": "^0.1.0"
  },
  "devDependencies": {
    "@scope/baz": "^0.1.0"
  }
}

{
  "name": "@scope/bar",
  "version": "0.1.0"
}

{
  "name": "@scope/baz",
  "version": "0.1.0"
}

And the following Git commits:

🌱 bar: some feature
🐞 baz: some fix

By running the following code there will be actions made automatically:

• get workspaces packages
• parse Git commits and collect all the necessary "bumps" for certain packages, including:
  • patch for @scope/baz: 0.1.1
  • minor for @scope/bar: 0.2.0
  • minor for @scope/foo because of dependency on @scope/bar: 0.2.0
  • dependency range update of @scope/bar for @scope/foo
  • dev dependency range update of @scope/baz for @scope/foo
• for each affected package:
  • write dependencies bumps to package.json file
  • make dependencies commit
  • write bumped version to package.json file
  • make bumped version commit
  • make bumped version tag
  • publish to NPM
• push commits and tags
• make GitHub release with markdown for each published package
