Sign-up Implementation

Explore how to implement user sign-up functionality by encrypting passwords, validating input data, updating the database, and generating JWT tokens. Gain the skills needed to securely register users and connect the sign-up process to HTTP routing within a Node.js backend.

We'll cover the following...

We’ll start implementing the sign-up functionality and all of its logic, which includes the following:

  • Encrypting the password.

  • Validating the data.

  • Updating the database with the new user.

  • Creating the JWT token for that user.

Let’s move directly to the implementation details:

  1. Navigate to the controllers directory and make a new file named user.js.

    cd controllers
touch user.js

  2. Install the bcrypt and jsonwebtoken packages.

    • The bcrypt package helps encrypt the user password before storing it in the database.

    • The jsonwebtoken package allows us to generate a signed JWT token. ...
