It extracts the entire body portion of an incoming request stream and exposes it on req.body. With the help of express, APIs can be build very easily and quickly.īcrypt is a library that helps us to hash passwords.īody-parser is required to handle HTTP POST request in Express.js. npm install express bcrypt body-parser -saveĮxpress is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications. Then,we’ll install express, bcrypt and body-parser by using the following command. After entering the information, package-lock.json and package.json files will be created.
