Schematics automate repetitive tasks like scaffolding components, configuring libraries with `ng add`, and handling breaking changes with `ng update`.
Although developed by the Angular team, schematics are an open-source tool that can be used with other frameworks like React or for any project transformation task.
Schematics provide atomic updates by operating on a virtual file system, which prevents leaving projects in a broken state if a script fails.
Install the Schematics CLI and use the `schematics blank` command to create a new collection, which is defined by a `collection.json` file.
Learn about the fundamental building blocks of schematics, including the `Tree`, `Rule`, and `Rule Factory`, and how to pass options to your scripts.
Use the `tree.create()` and `tree.rename()` methods to programmatically add, move, or rename files within your project structure.
The `chain` utility allows you to execute multiple rules sequentially, enabling composition of both internal and external schematics.
Leverage templates with interpolation and conditional logic to generate dynamic files, using concepts like `Source`, `Rule`, and `mergeWith` to apply them.
See how to read an existing file with `tree.read()` and replace its contents using `tree.overwrite()`, demonstrated with a live example.
Find links to the official documentation, demo repositories, and examples of third-party schematic collections like Clarity and NativeScript.
