@qiwi/multi-semantic-release

hacky semantic-release for monorepos

This fork of dhoub/multi-semantic-release replaces setImmediate loops and execa.sync hooks with event-driven flow and finally makes possible to run the most release operations in parallel.

Status

We're still using this lib as a part of our release infra, but we're gradually migrating to bulk-release. This means that we do not have many resources to develop this implementation actively, but we will continue to do it on a leftover basis.

Install

yarn add @qiwi/multi-semantic-release --dev

Usage

multi-semantic-release

Configuring Multi-Semantic-Release

multi-semantic-release can be configured a number of ways:

• A .multi-releaserc file, written in YAML or JSON, with optional extensions: .yaml/ .yml/ .json/ .js
• A multi-release.config.js file that exports an object
• A multi-release key in the workspace root package.json

Alternatively some options may be set via CLI flags.

Note: CLI arguments take precedence over options configured in the configuration file.

Options

Option	Type	CLI Flag	Description
dryRun	boolean	--dry-run	Dry run mode.
logLevel	String	--log-level	Sets the internal logger verbosity level: error, warn, info, debug, trace. Defaults to info.
debug	boolean	--debug	Output debugging information. Shortcut for --logLevel=debug.
silent	boolean	--silent	Turns off any log outputs.
extends	String | Array	N/A	List of modules or file paths containing a shareable configuration. If multiple shareable configurations are set, they will be imported in the order defined with each configuration option taking precedence over the options defined in the previous.
sequentialInit	boolean	--sequential-init	Avoid hypothetical concurrent initialization collisions.
sequentialPrepare	boolean	--sequential-prepare	Avoid hypothetical concurrent preparation collisions. True by default.
firstParent	boolean	--first-parent	Apply commit filtering to current branch only.
ignorePrivate	boolean	--ignore-private	Exclude private packages. True by default.
ignorePackages	String | Array	--ignore-packages	Packages list to be ignored on bumping process (appended to the ones that already exist at package.json workspaces). If using the CLI flag, supply a comma seperated list of strings.
tagFormat	String	--tag-format	Format to use when creating tag names. Should include "name" and "version" vars. Default: "${name}@${version}" which generates "package-name@1.0.0"
deps	Object	N/A	Dependency handling, see below for possible values.

deps Options

Option	Type	CLI Flag	Description
bump	override | satisfy | inherit	--deps.bump	Define deps version updating rule. Allowed: override, satisfy, inherit. override by default.
release	patch | minor | major | inherit	--deps.release	Define release type for dependent package if any of its deps changes. Supported values: patch, minor, major, inherit. patch by default
prefix	'^' | '~' | ''	--deps.prefix	Optional prefix to be attached to the next version if bump is set to override. '' by default.
pullTagsForPrerelease	boolean	--deps.pullTagsForPrerelease	Optional flag to use release tags for evaluating prerelease version bumping. Normally, this option will lead to dumping dependencies to a version past what was just released and tagged by semantic release. Only set this option to true if you previously had a workflow that compensated for the previous bug behavior. 'false' by default.

Examples

• Via multi-release key in the project's package.json file:

{
	"multi-release": {
		"ignorePackages": [
			"!packages/b/**",
			"!packages/c/**"
		],
		"deps": {
			"bump": "inherit"
		}
	}
}

• Via .multi-releaserc file:

{
	"ignorePackages": [
		"!packages/b/**",
		"!packages/c/**"
	],
	"deps": {
		"bump": "inherit"
	}
}

• Via CLI:

$ multi-semantic-release --ignore-packages=packages/a/**,packages/b/** --deps.bump=inherit

Configuring Semantic-Release

MSR requires semrel config to be added in any supported format for each package or/and declared in repo root (globalConfig is extremely useful if all the modules have the same strategy of release).
NOTE config resolver joins globalConfig and packageConfig during execution.

// Load the package-specific options.
const { options: pkgOptions } = await getConfig(dir);

// The 'final options' are the global options merged with package-specific options.
// We merge this ourselves because package-specific options can override global options.
const finalOptions = Object.assign({}, globalOptions, pkgOptions);

Make sure to have a workspaces attribute inside your package.json project file. In there, you can set a list of packages that you might want to process in the msr process, as well as ignore others. For example, let's say your project has 4 packages (i.e. a, b, c and d) and you want to process only a and d (ignore b and c). You can set the following structure in your package.json file:

{
	"name": "msr-test-yarn",
	"author": "Dave Houlbrooke <dave@shax.com",
	"version": "0.0.0-semantically-released",
	"private": true,
	"license": "0BSD",
	"engines": {
		"node": ">=8.3"
	},
	"workspaces": [
      "packages/*",
      "!packages/b/**",
      "!packages/c/**"
	],
	"release": {
		"plugins": [
			"@semantic-release/commit-analyzer",
			"@semantic-release/release-notes-generator"
		],
		"noCi": true
	}
}

You can also ignore it with the CLI:

$ multi-semantic-release --ignore-packages=packages/b/**,packages/c/**

You can also combine the CLI ignore options with the ! operator at each package inside workspaces attribute. Even though you can use the CLI to ignore options, you can't use it to set which packages to be released – i.e. you still need to set the workspaces attribute inside the package.json.

Verified usage examples

We use this tool to release our JS platform code inhouse (GitHub Enterprise + JB TeamCity) and for our OSS (GitHub + Travis CI). Guaranteed working configurations available in projects.
