- what is the Webiny CLI
- what are the commonly used commands
Overview
Webiny CLI (command line interface) is the central tool that you’ll be using throughout the complete project development process, in your terminal of choice.
Out of the box, it offers a couple of commands that will let you perform essential tasks like deployments, development and production code builds, different scaffolding, and so on.
Additionally, the Webiny CLI is pluggable, meaning you can easily create your own custom commands, or even replace the existing ones. Please visit the Adding Custom Commands guide for more information.
For a full list of commands, in your terminal of choice, make sure to run yarn webiny --help.

FAQ
Do I Need to Install Webiny CLI Manually?
No, Webiny CLI comes set up automatically with every new Webiny project. Note that it’s not installed as a global tool, but on a per-project basis. So, in theory, you could have two projects with different versions of the CLI.
Do I Need to Invoke the Webiny CLI Withyarn?
For the highest chance that everything will work as expected, we recommend you do so. But do note that if you’re using some of the alternative terminals, like for example Zsh, you might even get away without it.
