Nestch CLI Tool

Nestch is a command-line interface (CLI) tool designed to simplify the process of renaming resources in a NestJS application. This tool allows developers to quickly and efficiently change the names of resources, ensuring consistency and reducing the potential for errors.

Features

• Easily rename NestJS resources with a simple command.

• Built with TypeScript for type safety and better development experience.

• Modular design with separate files for commands and utility functions.

💡 RECOMMENDATION
The Nestch CLI tool is continuously being optimized and made more lightweight. All the latest features and performance improvements are included in the latest version, therefore, we strongly recommend always keeping the latest version.

Installation

# Install globally

npm install -g nestch

Usage

nestch rename <oldName> <newName> [options]

Aliases

• nestch rename can be shortened to nestch rn

• nestch change can be used as an alias for nestch rename

Options

• --type, -t: Specify the resource type to rename (e.g., module, controller, service)

• --help, -h: Show help

Examples

1. Rename a resource and all its references

   # Rename 'users' to 'members' in the current project
   
   nestch rename users members
   

2. Rename a specific resource type

   # Rename only the users controller
   
   nestch rename users members --type controller
   
   
   
   # Shorthand for the above
   
   nestch rn users members -t controller
   

3. Using the change alias

   nestch change users members
   

Requirements

• Must be run from the root of a NestJS project

• Project must have a src directory

• Project must have @nestjs/* dependencies in package.json

How It Works

1. The tool verifies it's being run in a NestJS project

2. It searches for files matching the old resource name in the src directory

3. It identifies the type of each file based on its name and content

4. It renames the files and updates all references in:

   • Import/export statements

   • Decorators (e.g., @Module, @Controller)

   • Class names

   • Variable names

   • File paths

   • Dependency injection tokens

Supported Resource Types

• Module

• Controller

• Service

• Entity

• DTO

• Guard

• Interceptor

• Pipe

• Filter

• Resolver

• Repository

• Gateway

• Subscriber

• Middleware

Notes

• The tool will only modify files in the src directory

• It will automatically skip node_modules, .git, and other common directories

• Always commit your changes before running the tool, just in case
