Building Modular NodeJS Codebase Using GPT Assistance

In the world of software development, creating modular and maintainable code is crucial for long-term success. The Cloving CLI tool, powered by advanced AI models like GPT, provides the perfect synergy between human ingenuity and artificial intelligence. Whether you are a seasoned developer or just starting in the NodeJS ecosystem, this blog post will guide you on building a robust modular NodeJS codebase with the help of Cloving CLI.

Getting Started

1. Setting Up Cloving CLI

Before we dive into building your NodeJS codebase, let’s ensure Cloving is set up properly.

Installation:
First, install Cloving globally using npm:

npm install -g cloving@latest

Configuration:
Configure Cloving with your API key and preferred models:

cloving config

Follow the interactive prompts to set up your AI model, API key, and preferences.

2. Initializing Your Project

Once Cloving is configured, set up your NodeJS project directory to leverage Cloving’s capabilities:

cloving init

This creates a cloving.json file that holds metadata about your application context.

3. Generating Code for Reusable Modules

A modular codebase is often based on reusable modules. Let’s generate a NodeJS module using Cloving:

Example:
Suppose you need a utility module for handling JSON files.

cloving generate code --prompt "Create a NodeJS module to read and write JSON files in a directory" --files utils/jsonHandler.js

The generated code might look like:

// utils/jsonHandler.js
const fs = require('fs');
const path = require('path');

function readJSONSync(filePath) {
  const fullPath = path.resolve(filePath);
  const data = fs.readFileSync(fullPath, 'utf-8');
  return JSON.parse(data);
}

function writeJSONSync(filePath, data) {
  const fullPath = path.resolve(filePath);
  fs.writeFileSync(fullPath, JSON.stringify(data, null, 2), 'utf-8');
}

module.exports = {
  readJSONSync,
  writeJSONSync,
};

4. Interactive Code Reviews

Keeping your code clean with regular reviews is part of maintaining a modular codebase. Use Cloving for AI-powered code reviews:

cloving generate review

Receive feedback on code quality, potential bugs, and improvements. Implement the suggested changes to keep your code modular.

5. Using Cloving Chat for Complex Requests

Integrate complex modules or solve deep-rooted bugs using Cloving’s interactive chat:

cloving chat -f handlers/requestHandler.js

Here you can ask Cloving for additional features or improvements, such as:

Add error handling to the requestHandler module.

6. Automating Test Creation

Automatically generate tests for your modules to ensure they are functioning correctly.

Example for the JSON handler module:

cloving generate unit-tests -f utils/jsonHandler.js

Generated tests might look like:

// utils/jsonHandler.test.js
const { readJSONSync, writeJSONSync } = require('./jsonHandler');
const fs = require('fs');

jest.mock('fs');

describe('JSON Handler', () => {
  beforeEach(() => {
    fs.readFileSync.mockClear();
    fs.writeFileSync.mockClear();
  });

  test('readJSONSync reads JSON correctly', () => {
    const mockData = '{"key": "value"}';
    fs.readFileSync.mockReturnValue(mockData);

    const data = readJSONSync('test.json');
    expect(data).toEqual({ key: 'value' });
  });

  test('writeJSONSync writes JSON correctly', () => {
    writeJSONSync('test.json', { key: 'value' });

    expect(fs.writeFileSync).toHaveBeenCalledWith('test.json', JSON.stringify({ key: 'value' }, null, 2), 'utf-8');
  });
});

7. Streamlining Git Commits

Maintain clear and descriptive commit histories by using Cloving for commits:

cloving commit

Review AI-generated commit messages that capture the essence of your code changes.
