Generators provide a way to automate many tasks you regularly perform as part of your development workflow. Whether it is scaffolding out components, features, ensuring libraries are generated and structured in a certain way, or updating your configuration files, generators help you standardize these tasks in a consistent, and predictable manner.
Types of Generators
There are three main types of generators:
- Plugin Generators are available when an Nx plugin has been installed in your workspace.
- Local Generators are generators that you can create for your own workspace. Local generators allow you to codify the processes that are unique to your own organization.
- Update Generators are invoked by Nx plugins when you update Nx to keep your config files in sync with the latest versions of third party tools.
Invoking Plugin Generators
Generators allow you to create or modify your codebase in a simple and repeatable way. Generators are invoked using the
nx generate command.
nx generate [plugin]:[generator-name] [options]
nx generate @nx/react:component mycmp --project=myapp
It is important to have a clean git working directory before invoking a generator so that you can easily revert changes and re-invoke the generator with different inputs.
Build your own Generator
Nx comes with a Devkit that allows you to build your own generator for your Nx workspace. Learn more about it on our docs page or have a look at the video below:
