What is the best approach to automate a deployment using gulp APIs?

What is the best approach to automate a deployment using gulp APIs with the following constraints:

The repository located in bit-bucket.
Steps:

pull latest changes from the master branch.

increment the version using this command "npm version patch".

execute build task.

push changes into the repository.

Does something like this can achieve what I want ?

"build": "git pull origin master && npm version patch && gulp && git push origin master",
