Node.js Deployment Mastery

What is the first step in setting up a Node.js environment?

• Manually write the entire Node.js codebase

• Download and install Node.js

• Skip setting up any environment

• Install Python instead of Node.js

How can you create a basic Node.js application?

• Install Node.js, create a new folder, run 'npm init', create main JavaScript file, start writing Node.js code

• Use a web browser, create a new folder, run 'npm init', create main JavaScript file, start writing Node.js code

• Download Node.js, create a new folder, run 'npm start', create main JavaScript file, start writing Node.js code

• Install Python, create a new folder, run 'npm init', create main JavaScript file, start writing Node.js code

Explain the process of deploying a Node.js application to a server.

• Environment variables do not need to be configured when deploying a Node.js application

• Starting the application is not necessary in the deployment process

• Deploying a Node.js application does not require installing dependencies

• Ensure Node.js is installed on the server, transfer application files, install dependencies, start the application, configure environment variables, and use process managers like PM2.

Why is configuring environment variables important for Node.js applications?

• Node.js applications cannot access environment variables.

• Environment variables help in securely storing sensitive information and configuration settings outside of the codebase.

• Environment variables are only used for debugging purposes.

• Configuring environment variables has no impact on Node.js applications.

What are some common methods for monitoring and scaling a Node.js application?

• Database queries, Frontend frameworks, Authentication protocols

• Monitoring tools, load balancers, caching mechanisms, containerization technologies

List some security measures that can be implemented in Node.js deployment.

• Using vulnerable packages

• No input validation

• HTTPS, input validation, vulnerability-free packages, CORS protection, authentication, authorization

• HTTP instead of HTTPS

What is NPM and how is it related to Node.js deployment?

• NPM is a database management system for Node.js deployment.

• NPM is a web browser for Node.js deployment.

• NPM is a package manager for Node.js and helps in managing dependencies for Node.js deployment.

• NPM is a programming language used for Node.js deployment.

What is the purpose of package.json file in a Node.js application?

• It is used to store user authentication details

• It serves as a manifest for the project, allowing developers to easily install dependencies, run scripts, and define project details.

• It provides a platform for playing games within the application

• It serves as a backup for the project's source code

Explain the difference between development and production environments in Node.js deployment.

• Development environment is for testing and debugging code, while production environment is where the final application runs for end-users.

• Development environment is where the final application runs for end-users, while production environment is for testing and debugging code.

• Development environment is for end-users, while production environment is for testing and debugging code.

• Both development and production environments are used interchangeably in Node.js deployment.

How can you handle dependencies in a Node.js application during deployment?

• Use a package.json file to list dependencies and run 'npm install' during deployment.

• Use a package-lock.json file to list dependencies and run 'npm deploy'

• Manually copy and paste dependencies into the deployment folder

• Ignore dependencies and hope for the best
