Welcome to the Node.js CLI Plugin Tutorial! This tutorial will guide you through the process of creating and registering custom plugins in the Node.js CLI text transformation application. By following these steps, you will learn how to extend the functionality of the CLI app with ease. Whether you're a beginner or an experienced developer, this tutorial will help you get started with plugin development.
Step 1 - Set Up the Project
Before we begin, let's make sure you have the base project set up. Clone this github repository and follow the instructions given on the README to run it on your local machine. Link to the repository - Node-CLI-Plugin-System
Step 2 - Create Plugin File
A) Create a New File:
Create a new file named alphabetCountPlugin.ts in your plugins directory.
B) Implement the Plugin:
In this file, you'll implement the TextPlugin interface and define the transformText method. This method will contain the logic to count the alphabets in the input text.
An example is provided below.
Step 3 - Surprise! Your plugin is already registered
Congratulations ! You've successfully created and registered your plugin
Here's how the system finds and registers your plugin
-
Setup: The code initializes a PluginManager and defines the path to the plugins directory where all plugin files are stored.
-
Registering Plugins: It reads all .js files in the plugins directory, extracting each file's name and registering it with the PluginManager. Each plugin is identified by its name and relative path.
-
Running the CLI: A TextCLI instance is created with the registered plugins, and cli.displayPrompt() starts the CLI, allowing users to interact with and apply text transformations using the available plugins.
