Just launched my Micro SaaS! Here's what tech stack I used.

A Google Chrome Extension that can get you email addresses from LinkedIn and Website URLs

Today I just got approved for my Google Chrome Extension, something on which I have been working for almost a month.

So here is what it does,

It’s an extension that can find the email address & phone number of your prospects from LinkedIn or a website.

The data is not getting returned from a database but rather it scrapes in real time from the internet live.

There are some reasons why I haven’t built the database yet, like for MVP I don’t like to invest my money and resources on infrastructure where I need to host more than 100 Millions of records.

It’s possible, but not at least for the MVP or while I’m testing the market.

So to build the frontend of the extension,

I’ve used Vite + React JS where Vite is the build tool and React JS is my frontend library.

I want to keep things light and simple so I tried not to add any big libraries and tried to write the code from scratch for most of the part.

For the styling side, it’s all on Tailwind CSS, with no wrapper or anything on Tailwind its core library.

Mostly on the front-end side, the most important file we have is manifest.json which contains all the necessary information for the Chrome extension like version, icons, permissions, and a lot more.

Make sure not to add any permission that you are not using, I made this mistake and in my first submission, it got rejected.

For the backend side,

The backend of the application is on Node JS and Express JS, and for the database side, MongoDB is being used.

For handling the authentication and user data right now, it’s a token-based system, you generate a token from seefunnel dashboard and add it to the extension.

I’m planning to move it to the proper login and logout page like others, but for the MVP this was the way I knew so I did it.

If you talk about the deployment it’s deployed on Microsoft Azure Cloud, and other services like DevOps, and Artifacts are being used from Azure.

This was pretty much of it.

Let me know if you have any questions in the comments, I would love to answer them.
