Usage
npm install
Back End - Contact Form
Technologies used:
- Firebase
- Firestore (NoSQL DB)
- Node
- Express
- Captcha v3
- Security Middleware (CORS, input validation)
I built this API to connect to my "Contact us" form and hosted on Google's Firebase (Cloud). Upon submitting, the form generates a token via Google's captcha V3 api. With the form values and the generated captcha token, the form is submitted to my server via a POST request. On my server, I implemented middleware and an Express endpoint to handle such a request. I used CORS middleware to only allow traffic from whitelisted domains as a security measure. I created middleware for basic input validation. I created middleware to validate the submitted form Captcha token sent with the form to prevent spam. Finally, I upload the valid form data into Firestore, Google's NoSQL database.
