1 - What is Node.js and what are its advantages?
Node.js is a JavaScript runtime environment that allows developers to run JavaScript code on the server side. It's fast, scalable, and event driven, making it ideal for building real time applications.
2) What are the core modules in Node.js and how do you use them?
Node.js comes with a set of core modules that provide essential functionality, such as file system operations, networking, and timers. To use these modules, you can simply require them in your code.
3) How do you create a server in Node.js?
To create a server in Node.js, you can use the http or https module. You can specify the port number and IP address that the server will listen on, and define callback functions to handle incoming requests.
4) How do you handle HTTP requests and responses in Node.js?
When a client sends an HTTP request to a server, Node.js will create an HTTP request object and an HTTP response object. You can use these objects to access the request and response headers, body, and other information. You can also use the response object to send a response back to the client.
5) How do you manage state in Node.js?
Node.js is a stateless environment, which means that it doesn't store any state between requests. To manage state, you can use session cookies, databases, or other mechanisms.
6) How do you handle errors in Node.js?
Errors in Node.js can be handled using the try catch block or the error event. You can also use the console.error() method to log errors to the console.
7) How do you debug a Node.js application?
There are several ways to debug a Node.js application, including using the debugger keyword, using the console.log() method, or using a debugging tool such as Node Inspector.
8) How do you deploy a Node.js application?
There are several ways to deploy a Node.js application, including using a cloud platform such as AWS or Heroku, or using a serverless platform such as AWS Lambda or Google Cloud Functions.
9) What are some best practices for developing Node.js applications?
Some best practices for developing Node.js applications include using a module system, following a code style guide, and using error handling and logging.
10) What are some popular Node.js frameworks?
Some popular Node.js frameworks include Express.js, Koa.js, and Hapi.js. These frameworks provide a set of tools and features that make it easier to develop Node.js applications.
11 - What are some popular Node.js testing frameworks?
Some popular Node.js testing frameworks include Mocha, Chai, and Sinon. These frameworks provide a set of tools and features that make it easier to test Node.js applications.
12) What are some popular Node.js deployment tools?
Some popular Node.js deployment tools include PM2, forever, and upstart. These tools help you manage Node.js applications in production, including starting, stopping, and restarting the application.
13) What are some popular Node.js logging libraries?
Some popular Node.js logging libraries include Winston, bunyan, and pino. These libraries provide a set of tools and features that make it easier to log messages from Node.js applications.
14) What are some popular Node.js package managers?
Some popular Node.js package managers include npm, yarn, and pnpm. These package managers help you manage Node.js packages, including installing, updating, and removing packages.
15) What are some popular Node.js CI/CD tools?
Some popular Node.js CI/CD tools include Jenkins, Travis CI, and CircleCI. These tools help you automate the building, testing, and deployment of Node.js applications.
