[Javascript] Automating Releases with semantic-release

There are so many repeated steps when releasing a new version of a library. The tool semantic-release automates this process by pushing off the responsibility of your releases to continuous integration. Trust us, this will change your workflow for the better.

Install:

npm i -D semantic-release

Run:

semantic-release-cli setup

You can choose Travis and Single Node instance for now.

Notice Semantic release require Travis account (if you choose to use Travis), so you need to create a Travis account with your Github account. So it will sync your repos. After this done. you can setup semantic release.

Semantic release will delete "version" from the package.json, it will auto handle version according to your commit.

Also it creates a travis.yml file, you can add script to make sure it runs test before it commits.
