Build Your Own JWT Decode Online Tool with Firebase Functions and React

Building a JWT decode online tool can be a valuable asset for any organization, allowing developers to quickly and easily verify the authenticity of JSON Web Tokens. In this tutorial, we'll use Firebase Functions and React to create a custom tool that can be deployed online.

First, we'll create a Firebase Function that handles the JWT decoding process. We'll use the Firebase Admin SDK to verify the token and extract the payload. Once the token is decoded, we'll use React to create a user-friendly interface for users to input the token and receive the decoded output.

We'll also cover best practices for securing the Firebase Function, including authentication and authorization. By the end of this tutorial, you'll have a custom JWT decode online tool that can be used to streamline your development workflow.
