Summary of Changes

Hello @bniladridas, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request establishes a foundational server-side component by adding a new Express.js application. It provides a simple API endpoint for searching and filtering a static dataset of tasks, laying the groundwork for future features that require backend data processing and retrieval.

Highlights

• New Server API: Introduces a new Express.js server in graphite-demo/server.js to provide a /search API endpoint.
• Task Filtering Endpoint: The new /search endpoint allows filtering a predefined list of tasks based on a query parameter, returning matching tasks as JSON.

Code Review

This pull request introduces a basic Express server with a /search API endpoint. The code is functional for its purpose. My review includes suggestions to improve configuration management by using environment variables for the port, enhance robustness by adding error handling to the API route, and follow common file formatting conventions by adding a newline at the end of the file. These changes will make the server more configurable and resilient.

[gemini-code-assist]

The server port is hardcoded. It's a best practice to use environment variables for configuration like this, which allows for greater flexibility across different deployment environments (e.g., development, staging, production) without code changes.

Suggested change

	const port = 3000;
	const port = process.env.PORT || 3000;

[gemini-code-assist]

The /search route handler lacks explicit error handling. If an unexpected error occurs during processing (e.g., if the tasks data were malformed in a real-world scenario), the server could become unresponsive or crash. It's safer to wrap the logic in a try...catch block to handle potential errors gracefully and return a meaningful error response to the client.

Suggested change

	app.get('/search', (req, res) => {
	// Retrieve the query parameter
	const query = req.query.query?.toLowerCase() || '';
	// Filter tasks based on the query
	const filteredTasks = tasks.filter(task => task.description.toLowerCase().includes(query));
	res.json(filteredTasks);
	});
	app.get('/search', (req, res) => {
	try {
	// Retrieve the query parameter
	const query = req.query.query?.toLowerCase() || '';
	// Filter tasks based on the query
	const filteredTasks = tasks.filter(task => task.description.toLowerCase().includes(query));
	res.json(filteredTasks);
	} catch (error) {
	console.error('Error during search:', error);
	res.status(500).json({ message: 'Internal Server Error' });
	}
	});

This file is missing a final newline character. It's a widely-followed convention to end files with a single newline. This prevents issues with certain tools and file manipulations (like concatenation). Most editors can be configured to add this automatically.
