Release-task NPM

release-task

A package to automate releasing for git projects. Out of the box this package does the following:

bump: Increment the package.json file version property, to add more files see the options below.
changelog: Updates the changelog with the latest commits that has not been pushed to origin.
commit: Commit those files which had version constraint bumped i.e: package.json, changelog.md.
tag: Create a new annotated tag for the new release version.

Install

$ npm i release-task --save-dev

Usage

Create a script file that could be run via npm scripts like: ./scripts/release.js

const releaseTask = require('release-task');
tasks.init();

Add a new script within package.json

{
  "scripts": {
    "release": "node ./scripts/release.js"
  }
}

$ npm run release

To see how this package handle releasing commits, changelog and tags take a look in its own releasing commit and tag releases

Adding custom tasks

Tasks are functions that do something and return a Promise, by default there are four defined tasks already defined, but it's possible to create your own custom task to run after the default tasks gets completed.

Task queued, in order to get executed each step without missing something on the way, i.e commit a file without changelog content being updated. So because of this we run tasks as an array of functions in series using run-series.

Default Options

option	type	description
`currentVersion`	`string`	the current project version defined in your `package.json`.
`bumpFiles`	`array`	files that should have version property bumped.
`commitFiles`	`array`	files that should be commit after changes.
`commitMessage`	`string`	the format of the commit message for the release.
`changelog`	`object`	default options for the changelog.
`changelog.gitChangeLog`	`string`	the git command used to list and format the changelog.
`changelog.gitChangeLogArguments`	`array`	list of arguments that git should run to generate the changelog.
`changelog.filename`	`string`	the change log file name.
`changelog.header`	`string`	the default header for changelog.
`changelog.template`	`string`	the default format for the list of the latest commit.
`tagFormatCmd`	`string`	the git command to format the tag message commit.
`tagName`	`string`	the default tag format i.e: `v1.2.3`.
`tagMessage`	`string`	the default title for the annotated tag message.
`config.indentSize`	`number`	the default indent size for JSON files changes.

Function Tasks

Every task receives two params, the incremented version string, and the configuration options:

const util = require('util');
const exec = util.promisify(require('child_process').exec);

const customTask = async (version, options) => {
  // Task body is basically:
  // do something with the already incremented version
  // access to the config options
  // onError throw any message string
  // onSuccess return a message string
  const { stdout, stderr } = await exec('ls -lah');
  if (stderr) {
    throw new Error('Error Message!');
  }
  return stdout;
}

When build a custom task the function will always receive the bumbed version and the options of the prompt.
