Install

npm install conventional-recommended-bump

Usage

const conventionalRecommendedBump = require(`conventional-recommended-bump`);

conventionalRecommendedBump({
  preset: `angular`
}, (error, recommendation) => {
  console.log(recommendation.releaseType); // 'major'
});

npm install --global conventional-recommended-bump
conventional-recommended-bump --help

API

conventionalRecommendedBump(options, [parserOpts,] callback);

parserOpts is optional.

In the case you don't want to provide parserOpts, then callback must be provided as the second argument.

options

options is an object with the following properties:

ignoreReverted
preset
config
whatBump

ignoreReverted

Type: boolean Default: true

If true, reverted commits will be ignored.

preset

Type: string

It's recommended to use a preset so you don't have to define everything yourself.

The value is passed to conventional-changelog-preset-loader.

config

Type: object

This should serve as default values for other arguments of conventional-recommended-bump so you don't need to rewrite the same or similar config across your projects.

NOTE: config option will be overwritten by the value loaded by conventional-changelog-preset-loader if the preset options is set.

whatBump

Type: function

A function that takes parsed commits as an argument.

whatBump(commits) {};

commits is an array of all commits from last semver tag to HEAD as parsed by conventional-commits-parser

This should return an object including but not limited to level and reason. level is a number indicating what bump it should be and reason is the reason of such release.

tagPrefix

Type: string

Specify a prefix for the git tag that will be taken into account during the comparison.

For instance if your version tag is prefixed by version/ instead of v you would specifying --tagPrefix=version/ using the CLI, or version/ as the value of the tagPrefix option.

skipUnstable

Type: boolean

If true, unstable tags will be skipped, e.g., x.x.x-alpha.1, x.x.x-rc.2

lernaPackage

Type: string

Specify the name of a package in a Lerna-managed repository. The package name will be used when fetching all changes to a package since the last time that package was released.

For instance if your project contained a package named conventional-changelog, you could have only commits that have happened since the last release of conventional-changelog was tagged by specifying --lernaPackage=conventional-changelog using the CLI, or conventional-changelog as the value of the lernaPackage option.

path

Type: string

Specify the path to only calculate with git commits related to the path. If you want to calculate recommended bumps of packages in a Lerna-managed repository, path should be use along with lernaPackage for each of the package.

parserOpts

Type: object

See the conventional-commits-parser documentation for available options.

callback

Type: function

callback(error, recommendation) {};

recommendation is an object with a single property, releaseType.

releaseType is a string: Possible values: major, minor and patch, or undefined if whatBump does not return sa valid level property, or the level property is not set by whatBump.

Debugging

To assist users of conventional-recommended-bump with debugging the behavior of this module we use the debug utility package to print information about the release process to the console. To enable debug message printing, the environment variable DEBUG, which is the variable used by the debug package, must be set to a value configured by the package containing the debug messages to be printed.

To print debug messages on a unix system set the environment variable DEBUG with the name of this package prior to executing conventional-recommended-bump:

DEBUG=conventional-recommended-bump conventional-recommended-bump

On the Windows command line you may do:

set DEBUG=conventional-recommended-bump
conventional-recommended-bump

Node Support Policy

We only support Long-Term Support versions of Node.

We specifically limit our support to LTS versions of Node, not because this package won't work on other versions, but because we have a limited amount of time, and supporting LTS offers the greatest return on that investment.

It's possible this package will work correctly on newer versions of Node. It may even be possible to use this package on older versions of Node, though that's more unlikely as we'll make every effort to take advantage of features available in the oldest LTS version we support.

As each Node LTS version reaches its end-of-life we will remove that version from the node engines property of our package's package.json file. Removing a Node version is considered a breaking change and will entail the publishing of a new major version of this package. We will not accept any requests to support an end-of-life version of Node. Any merge requests or issues supporting an end-of-life version of Node will be closed.

We will accept code that allows this package to run on newer, non-LTS, versions of Node. Furthermore, we will attempt to ensure our own changes work on the latest version of Node. To help in that commitment, our continuous integration setup runs against all LTS versions of Node in addition the most recent Node release; called current.

JavaScript package managers should allow you to install this package with any version of Node, with, at most, a warning if your version of Node does not fall within the range specified by our node engines property. If you encounter issues installing this package, please report the issue to your package manager.
