8.0.9 • Public • Published


Smart CLI utility to safely and automatically do every step to release a new version of a library hosted on GitHub and published on npm.


npm i -g smooth-release


Simply run smooth-release from your root folder, that's all :)

Custom settings

  • Every config value used by smooth-release is overridable: jump to .smooth-releaserc section to know more about it.
  • You can run or turn off specific tasks also by passing a set of CLI arguments: jump to CLI arguments section to know more about it.

What it does

smooth-release does five main activities in this order:

  1. Run validations
  2. Increase version and push new commit and tag
  3. Generate
  4. Create release on GitHub with link to relative section in
  5. Publish on npm

Run validations

In order to proceed each one of these validations must pass (they can be optionally turned off):

  1. Current branch must be the one defined in .smooth-releaserc (default: "master")
  2. Local branch must be in sync with remote
  3. No uncommited changes in the working tree
  4. No untracked filed in the working tree
  5. User must be logged in "npm" and have write permissions for current package

Increase version

Check if version should be considered "breaking" or not

smooth-release automatically detects if the next version should be "breaking" or not. If a version is "breaking" it will be a major otherwise it will be a patch. smooth-release never creates a minor version.

To decide if a version is "breaking", smooth-release analyzes every closed issue (or merged pull request) from GitHub: if there is at least one valid closed issue marked as "breaking" the version will be breaking.

To mark an issue (or pull request) as "breaking" you can add to it a label named as you like. This label should also be added to smooth-releaserc to let smooth-release know about it.

NOTE: you can use pull requests instead of issues by setting github.dataType in .smooth-releaserc to "pullRequests"

MANUAL OVERRIDE: If you need to, you can override this step by manually passing the desired version/increase level as argument to smooth-release:

smooth-release minor
smooth-release pre-major
smooth-release 5.4.6

npm version and push


  1. npm version ${newVersion} --no-git-tag-version


The script to generate the changelog is basically a replica in JavaScript of github-changelog-generator.

The changelog is generated using closed issues by default. You can use merged pull requests instead by setting github.dataType in .smooth-releaserc to "pullRequests"

This script is stateless: every time it runs it replaces with a new one.

You can see an example by looking at the file on this repo:

Create release on GitHub with link to section

It statelessly creates a GitHub release for the last npm-version tag.

smooth-release defines an npm-version tag as a tag named v1.2.3 where 1, 2, 3 can be any number.

The release is named after the tag (ex: v1.2.3) and the body contains a link to the relative section in

You can see an example by looking at any release from this repo:

Create release commit and push it on origin

This step is run only if there are changes to commit. This may happen if you run one of these scripts:

  • npm-version (modifies package.json)
  • changelog (modifies

If the only file that changed is the new commit will have as message "Update".

Otherwise, if you run also npm-version script and therefore the package.json has been updated, the new commit will have the standard version message ("1.2.3") and will also have the npm-version tag (v.1.2.3).

Publish on npm


  1. npm publish


smooth-release comes with a safe default for each config value. This is the defaultConfig JSON used by smooth-release:

  github: {
    dataType: 'issues',
    changelog: {
      outputPath: './',
      ignoredLabels: ['DX', 'invalid', 'discussion'],
      bug: {
        title: '#### Fixes (bugs & defects):',
        labels: ['bug', 'defect']
      breaking: {
        title: '#### Breaking:',
        labels: ['breaking']
      feature: {
        title: '#### New features:'
  publish: {
    branch: 'master',
    inSyncWithRemote: true,
    noUncommittedChanges: true,
    noUntrackedFiles: true,
    validNpmCredentials: true,
    validGithubToken: true,
    packageFilesFilter: 'files',
    npmVersionConfirmation: true
  tasks: {
    validations: true,
    'npm-publish': null,
    'npm-version': null,
    'gh-release': null,
    'gh-release-all': false,
    changelog: null

If you set a task to null, smooth-release will prompt you every time before running the task: image

If you want to change parts of the default config you can define a JSON file in the root directory of your project named .smooth-releaserc.

The file will be recursively merged into defaultConfig (NB: arrays are replaced, not merged!).

CLI arguments

smooth-release can be configured using CLI arguments as well.

The main argument is passed directly to the npm-version task so you can use smooth-release like npm version:

smooth-release minor

You can also override the default behavior of each task by passing it as argument:


smooth-release --no-npm-publish # safely run "smooth-release" without publishing on "npm" 
smooth-release --changelog --gh-release-all # first time using smooth-release on your repo? this way you add a and a GitHub release for every npm verison tag :) 

If you specify one ore more negative argument, interactive prompts will be displayed for the remaining arguments (ex: --no-changelog).

If you specify one or more positive argument, all interactive prompts will be disabled and only the whitelisted tasks will be run (ex: --changelog).
