@nomadland/mono v0.3.4

@nomadland/mono

Monorepo development & continuous integration tooling.

Motivation

When we released monorepo, a headache problem was that release flow failed but some packages had been published to NPM. At this time, you may discard current release, or publish manually one by one, but it's quite troublesome in a monorepo with a large number of packages.

mono introduced a post patch process, it helps you to continue current release with visible release status.

Features

• Restartable release flow, powered by a post patch release process with visible release status.
• Quickly launch on-demand development build for monorepo.
• Generated changelog with author.

Install

npm i -g @nomadland/mono # globally
npm i -D @nomadland/mono # as devDependencies

Usage

A complete release workflow

If you had a monorepo as:

.
├── lerna.json
├── package.json
└── packages
    ├── foo
    ├── bar
    ├── baz
    └── qux

If current version is 2.1.1, after a period of time, I decide to release a patch version with latest version, so I execute:

mono release

You'll receive a prompt log to choose a release version, and you selected 2.1.2 to continue.

If release process got failed, you'll see a visible release status under patch stage:

Just select Y to finish release for all unpublished packages.

Execute build after bump version

You may execute mono release after build packages, but if your build process generated assets that contains the version of each, you'll get a wrong version at final NPM assets, you can execute build after version is bumped:

mono release --build --ignore-scripts 
# Note that --ignore-scripts is required if you set `prepublishOnly` for sub packages.

Independent patch process

Patch process has been integrated into release flow, you can also use it separately:

mono patch --tag=latest       # launch patch process with latest tag.

Generate Changelog

Changelog process has been integrated into release flow, You can also use it separately:

mono changelog # generate changelog

The equivalent command under release flow is:

mono changelog --beautify --commit --gitPush --attachAuthor --authorNameType name

Attach commit author

mono changelog --attachAuthor

Commits under generated changelog will be attached with commit author:

 ### Bug Fixes
 
-* **scope:** xx ([d1cfea5](...))
