# Mutates
[](https://mutates.katsuba.dev)
🚀 **Mutates** is a powerful toolset for mutating the Abstract Syntax Tree (AST) of TypeScript
files. It is a fork of `ng-morph`, with a broader focus beyond Angular-specific transformations,
allowing for extensive AST modifications in any TypeScript project.
## Features
✨ **AST Mutations:** Modify the AST of any TypeScript file.
🌐 **Framework-Agnostic:** Not limited to Angular; can be used with any TypeScript-based project.
🔧 **Extensible:** Framework-specific transformations are available through separate packages.
## Packages
### Core Package
#### @mutates/core
The core package provides the essential functionalities needed to manipulate the AST of TypeScript
files. It serves as the foundation for other specialized packages.
### Framework-Specific Packages
Framework-specific transformations have been decoupled from the core package and are available as
separate packages. For example:
#### @mutates/angular
This package includes transformations specific to Angular projects, leveraging the capabilities of
`@mutates/core` to provide Angular-focused AST modifications.
#### @mutates/nx
This package includes transformations specific to Nx workspaces, allowing for Nx-specific filesystem
operations and AST modifications.
## Installation
To install the core package, use the following command:
```sh
npm install @mutates/core
```
For Angular-specific transformations, install the Angular package as well:
```sh
npm install @mutates/angular @mutates/core
```
For Nx-specific transformations, install the Nx package:
```sh
npm install @mutates/nx @mutates/core
```
## Usage
### Basic Example
Here is a simple example demonstrating how to use `@mutates/core` to modify a TypeScript file:
```typescript
import { addFunctions, creataProject, createSourceFile, saveProject } from '@mutates/core';
// Initialize a new project
createProject();
// Add a TypeScript file to the project
createSourceFile(
'example.ts',
`
const greet = (name: string) => {
return 'Hello, ' + name;
};
`,
);
// Perform some transformations
addFunctions('example.ts', {
name: 'farewell',
isExported: true,
statements: "return 'buy!'",
});
// Save the modified file
saveProject();
```
### Angular Example
To perform Angular-specific transformations, use `@mutates/angular` along with `@mutates/core`:
```typescript
import { addProviders, getComponents } from '@mutates/angular';
import { createProject, createSourceFile, saveProject } from '@mutates/core';
// Initialize a new Angular project
createProject();
// Add an Angular component file to the project
createSourceFile(
'app.component.ts',
`
import { Component } from '@angular/core';
@Component({
selector: 'app-root',
template: '
Hello, World!
'
})
export class AppComponent {}
`,
);
// Perform some Angular-specific transformations
addProviders(getComponents('app.component.ts').at(0)!, ['AppService']);
// Save the modified file
saveProject();
```
