version-and-release

Tools for automating maintenance of a multi-repo project.

The main export (and the included bin/generate-release-notes script) generates release notes of all the dependency changes that you main package release contains.

The script compares package.json files from your previous version and the current one, finds all updated dependencies. Then gets all the tags that the dependencies changes contain, and loads their release notes. The output of the script is a string containing grouped by priority (major|minor|patch) release notes. The output can be customized with a template (see template option).

Usage

To generate release notes of all the dependency changes that you main package release contains:

const getReleaseNotes = require('version-and-release');
const options = {
  token: "your github token",
  owner: "canjs",
  repo: "canjs",
};
const output = getReleaseNotes('v6.3.0', 'v6.4.0', options);
// >>> "# Major \n ## [can-connect v2.0.0](https://github.com/canjs/can-connect/releases/tag/v6.0.0) ..."

Note: default value for both repo and owner is "canjs". Default (and the only implemented) git provider is "github".

Default template

The default template src/release-template.js formats output like this (demo):

# Major

## [<packageName> <version> - <description>](url-to-release)
<body>
...

# Minor

## [<packageName> <version> - <description>](url-to-release)
<body>
...

# Patch

- [<packageName> <version> - <description>](url-to-release)

- [<packageName> <version> - <description>](url-to-release)
...

All options:

Function getReleaseNotes takes 3 arguments:

Previous release version.
Current release version.
Options, an object with the following props:

token, a string with auth token (for GitHub see https://github.com/blog/1509-personal-api-tokens);
owner, a string with owner account name;
repo, a string with repository name;
provider, a string to choose what git provider to use (e.g. "github, "gitlab"); default "github";
template, a function that should expect changes grouped by priority (see default template);
maxTagsToLoad, a number that limits how many tags to load per dependency package; default 30, for GitHub max is 100;
maxTagsToInclude, a number that limits how many releases of every dependency package to include; default 10.

CLI usage

After adding the package to you dev dependencies you can access the node script from node_modules/.bin folder:

$ node_modules/.bin/generate-release-notes \
    --token=<token> \
    --repo=canjs \
    --owner=canjs \
    --template="../test/sample-template.js" \
    --provider=github \
    v6.3.0 v6.4.0

or using single char aliases:

$ node_modules/.bin/generate-release-notes \
    -T <token> \
    -r canjs \
    -o canjs \
    -t "../test/sample-template.js" \
    -p github \
    v6.3.0 v6.4.0

Demo

Add the package to your project:

$ cd canjs
$ npm add --save-dev "version-and-release";

Run script for CanJS (default repo) releases v6.3.0 to v6.4.0:

$ node_modules/.bin/generate-release-notes -T <token> \
v6.3.0 v6.4.0

Intermediary info with updated dependencies looks like this:

{ 
  'can-connect': { currentVer: '4.0.2', prevVer: '4.0.1' },
  'can-event-queue': { currentVer: '1.1.8', prevVer: '1.1.7' },
  'can-observable-array': { currentVer: '1.0.7', prevVer: '1.0.6' },
  'can-queues': { currentVer: '1.3.2', prevVer: '1.3.1' },
  'can-view-live': { currentVer: '5.0.4', prevVer: '5.0.3' } 
}

The output that gets passed to the template script is below.

You can also provide a path to your own template using --template option, otherwise the default template will be used.
