Preparing for Deployment

This video tutorial covers the preparation steps needed before deploying a React application to Heroku. It explains how to build static assets for React, configure the backend to serve these assets in production, and test the setup locally. The tutorial also outlines the final steps required for deploying to Heroku, including installing necessary tools and setting up Git.

Why is it necessary to build static assets for React before deploying to Heroku?

• To enable the use of React Dev tools

• To reduce the size of the application

• To ensure the application runs in production mode

• To allow the application to run on multiple servers

What command is used to create an optimized production build of a React app?

• npm run dev

• npm run build

• npm install

• npm start

In the context of serving static files, what does the 'express.static' middleware do?

• It compiles the React app

• It serves static files from a specified directory

• It sets up API routes

• It initializes the database connection

What is the purpose of setting 'process.env.NODE_ENV' to 'production'?

• To configure the application for production deployment

• To optimize the application for development

• To enable debugging features

• To allow the use of experimental features

How does the server determine which file to serve for non-API routes in production?

• It serves a maintenance page

• It redirects to the home page

• It serves the index.html file from the build folder

• It serves a default error page

What command should be used to start the server in production mode?

• npm test

• npm run dev

• npm build

• npm start

Which tools are necessary for deploying a React app to Heroku?

• Node.js and NPM

• Docker and Kubernetes

• Webpack and Babel

• Heroku CLI and Git
