Automate release workflow
If your project follows a semantic versioning, it may be a good idea to automatize the steps needed to do a release. Below you have a simple recipe that bumps the project version, commits the changes to git and creates a new tag.
var gulp = require('gulp');
var runSequence = require('run-sequence');
var conventionalChangelog = require('gulp-conventional-changelog');
var conventionalGithubReleaser = require('conventional-github-releaser');
var bump = require('gulp-bump');
var gutil = require('gulp-util');
var git = require('gulp-git');
var fs = require('fs');
gulp.task('changelog', function () {
return gulp.src('CHANGELOG.md', {
buffer: false
})
.pipe(conventionalChangelog({
preset: 'angular' // Or to any other commit message convention you use.
}))
.pipe(gulp.dest('./'));
});
gulp.task('github-release', function(done) {
conventionalGithubReleaser({
type: "oauth",
token: '0126af95c0e2d9b0a7c78738c4c00a860b04acc8' // change this to your own GitHub token or use an environment variable
}, {
preset: 'angular' // Or to any other commit message convention you use.
}, done);
});
gulp.task('bump-version', function () {
// We hardcode the version change type to 'patch' but it may be a good idea to
// use minimist (https://www.npmjs.com/package/minimist) to determine with a
// command argument whether you are doing a 'major', 'minor' or a 'patch' change.
return gulp.src(['./bower.json', './package.json'])
.pipe(bump({type: "patch"}).on('error', gutil.log))
.pipe(gulp.dest('./'));
});
gulp.task('commit-changes', function () {
return gulp.src('.')
.pipe(git.add())
.pipe(git.commit('[Prerelease] Bumped version number'));
});
gulp.task('push-changes', function (cb) {
git.push('origin', 'master', cb);
});
gulp.task('create-new-tag', function (cb) {
var version = getPackageJsonVersion();
git.tag(version, 'Created Tag for version: ' + version, function (error) {
if (error) {
return cb(error);
}
git.push('origin', 'master', {args: '--tags'}, cb);
});
function getPackageJsonVersion () {
// We parse the json file instead of using require because require caches
// multiple calls so the version number won't be updated
return JSON.parse(fs.readFileSync('./package.json', 'utf8')).version;
};
});
gulp.task('release', function (callback) {
runSequence(
'bump-version',
'changelog',
'commit-changes',
'push-changes',
'create-new-tag',
'github-release',
function (error) {
if (error) {
console.log(error.message);
} else {
console.log('RELEASE FINISHED SUCCESSFULLY');
}
callback(error);
});
});
