oao all --parallel

A Yarn-based, opinionated monorepo management tool.

Why? <g-emoji class=“g-emoji” alias=“sparkles” fallback-src=“https://github.githubassets.com/images/icons/emoji/unicode/2728.png”>✨</g-emoji>

  • Works with yarn, hence (relatively) fast!.
  • Simple to use and extend (hope so!).
  • Provides a number of monorepo workflow enhancers: installing all dependencies, adding/removing/upgrading sub-package dependencies, validating version numbers, determining updated sub-packages, publishing everything at once, updating the changelog, etc.
  • Supports yarn workspaces, optimising the monorepo dependency tree as a whole and simplifying bootstrap as well as dependency add/upgrade/remove.
  • Prevents some typical publish errors (using a non-master branch, uncommitted/non-pulled changes).
  • Runs a command or package.json script on all sub-packages, serially or in parallel, optionally following the inverse dependency tree.
  • Provides an easy-to-read, detailed status overview.
  • Support for non-monorepo publishing: benefit from oao’s pre-publish checks, tagging, version selection, changelog updates, etc. also in your single-package, non-monorepos.

Assumptions <g-emoji class=“g-emoji” alias=“thought_balloon” fallback-src=“https://github.githubassets.com/images/icons/emoji/unicode/1f4ad.png”>💭</g-emoji>

As stated in the tagline, oao is somewhat opinionated and makes the following assumptions on your monorepo:

  • It uses a synchronized versioning scheme. In other words: a master version is configured in the root-level package.json, and sub-packages will be in sync with that version (whenever they are updated). Some sub-packages can be left behind version-wise if they’re not updated, but they’ll jump to the master version when they get some love.
  • You use git for version control and have already initialised your repo.
  • Git tags are used for releases (and only for releases), and follow semver: v0.1.3, v2.3.5, v3.1.0-rc.1 and so on.
  • Some sub-packages may be public, others private (flagged "private": true in package.json). OK, no assumption here: rest assured that no private sub-packages will be published by mistake.

Installation

If yarn is not installed in your system, please install it first. If you want to use yarn workspaces (available since yarn 0.28), enable them by running yarn config set workspaces-experimental true and configure the following in your monorepo package.json (replace the glob patterns for your subpackages/workspaces as needed):

"workspaces": [
  "packages/*"
]

Add oao to your development dependencies (use the -W flag to avoid Yarn’s warning when installing dependencies on the monorepo root):

$ yarn add oao --dev -W

Main commands

In recent versions of npm, remember that you can run oao commands conveniently with the npx tool:

$ npx oao bootstrap
$ npx oao add my-subpackage my-new-dependency --dev
$ npx oao publish

This uses the local oao package inside your monorepo.

oao status

Provides lots of information on the git repo (current branch, last tag, uncommitted/unpulled changes) and subpackage status (version, private flag, changes since last tag, dependencies).

oao status

oao bootstrap

Installs all sub-package dependencies using yarn. External dependencies are installed normally, whereas those belonging to the monorepo itself (and custom links specified with the --link option) are yarn linked. Note that dependencies may end up in different places depending on whether you use yarn workspaces or not (see above).

Development-only dependencies can be skipped by enabling the --production option, or setting the NODE_ENV environment variable to production. Other flags that are passed through to yarn install include --frozen-lockfile, --pure-lockfile and --no-lockfile.

oao clean

Removes node_modules directories from all sub-packages, as well as from the root package.

oao add <sub-package> <deps...>

Adds one or several dependencies to a sub-package. For external dependencies, it passes through yarn add's flags. Internal dependencies are linked. Examples:

$ oao add subpackage-1 jest --dev
$ oao add subpackage-2 react subpackage-1 --exact

oao remove <sub-package> <deps...>

Removes one or several dependencies from a sub-package. Examples:

$ oao remove subpackage-1 jest
$ oao remove subpackage-2 react subpackage-1

oao remove-all <deps...>

Remove one or deveral dependencies from the monorepo (root and subpackages). It automatically runs oao bootstrap after upgrading the package.json files as needed. Examples:

$ oao remove-all leftpad
$ oao remove-all leftpad rightpad centerpad

oao upgrade <sub-package> [deps...]

Upgrade one/several/all dependencies of a sub-package. For external dependencies, it will download the upgraded dependency using yarn. For internal dependencies, it will just update the sub-package’s package.json file. Examples:

$ oao upgrade subpackage-1 jest@18.0.1
$ oao upgrade subpackage-2 react subpackage-1@3.1.2
$ oao upgrade subpackage-3

oao bump <deps...>

Upgrade one or several dependencies to either their latest version or to a specific version range. In case of internal dependencies, if no version range is given the current version will be used. It automatically runs oao bootstrap after upgrading the package.json files as needed. Examples:

$ oao bump moment
$ oao bump react@^16 react-dom@^16
$ oao bump subpackage-2

oao outdated

Runs yarn outdated on all sub-packages, as well as the root package.

oao prepublish

Carries out a number of chores that are needed before publishing:

  • Checks that all version numbers are valid and <= the master version.
  • Copies <root>/README.md to the main sub-package (the one having the same name as the monorepo).
  • Copies <root>/README-LINK.md to all other sub-packages.
  • Copies several fields from the root package.json to all other package.json files: description, keywords, author, license, homepage, bugs, repository.

oao publish

Carries out a number of steps:

  • Asks the user for confirmation that it has built all sub-packages for publishing (using something like yarn build).
  • Performs a number of checks:
    • The current branch should be master.
    • No uncommitted changes should remain in the working directory.
    • No unpulled changes should remain.
  • Determines which sub-packages need publishing (those which have changed with respect to the last tagged version).
  • Asks the user for an incremented master version (major, minor, patch or pre-release major), that will be used for the root package as well as all updated sub-packages.
  • Asks the user for final confirmation before publishing.
  • Updates versions in package.json files, commits the updates, adds a tag and pushes all the changes.
  • Publishes updated sub-packages.

There are lots of custom options for oao publish. Chances are, you can disable each one of the previous steps by means of one of those options. Check them all with oao publish --help.

Note: There is a problem when running oao publish as a script run with yarn. As a workaround, either run oao publish manually from the command line, or put it in a script and run it with npm, not yarn.

oao all <command>

Executes the specified command on all sub-packages (private ones included), with the sub-package’s root as current working directory. Examples:

$ oao all ls
$ oao all "ls -al"
$ oao all "yarn run compile"
$ oao all --tree "yarn run compile"

By default, oao all runs sequentially. Sometimes you must run commands in parallel, for example when you want to compile all sub-packages with a watch option:

$ oao all "yarn run compileWatch" --parallel

Note: some terminals may have problems with parallel logs (based on terminal-kit). If you experience issues, use the --no-parallel-logs flag. If you’re using the default terminal or Hyper on OS X or Windows, you should be fine.

Use --tree if you want to follow the inverse dependency tree (starting from the tree leaves).

You can also pass extra arguments to the command separating them with a --: oao all ls -- -al is equivalent to oao all 'ls -al'. This can be useful for adding extra commands to scripts in package.json.

oao run-script <script>

Similar to oao all <command>, it executes the specified (package) script on all sub-packages. Missing scripts will be skipped. Examples:

$ oao run-script start
$ oao run-script start --parallel
$ oao run-script start --tree

By default, oao run-script runs sequentially. Use --parallel to run the scripts in parallel, and --tree if you want to follow the inverse dependency tree (starting from the tree leaves).

You can also run all scripts matching a given glob pattern: oao run-script test:*.

  • lerna: for general inspiration.
  • yarn: for a fast, secure and reliable way to do dependency management.
  • np: for the prepublish checks.

Why oao? <g-emoji class=“g-emoji” alias=“sunglasses” fallback-src=“https://github.githubassets.com/images/icons/emoji/unicode/1f60e.png”>😎</g-emoji>

Basically, many other names I could come up with were either too boring (mono-repo), or already taken. oao stands for one and only <g-emoji class=“g-emoji” alias=“grimacing” fallback-src=“https://github.githubassets.com/images/icons/emoji/unicode/1f62c.png”>😬</g-emoji>, which is a reference to the individual nature of monorepos, as well as a beautiful song by Adele. Yes, I agree it’s far-fetched, but extremely short and convenient!
