My Learnings

• Zod
  • Earlier I have used express-validator. This is the first time I am using Zod. It has lot of tiny inbuild validators which I used to write by myself in express-validator
  • I liked its way of presenting the errors in a structured manner. And it also generates error messages itself
• Swagger
  • Swagger is good for large projects but personally I didn't liked it much due to its highly verbose syntax
• Docker
  • This was a bit challenging part
• Google Calendar Integration
  • This was the most challenging part as well as the part where I learnt the most
  • Most of the time for the project creation went in this
  • Learnt a lot about OAuth and how it works

My Journey

First I set up the basic structure like the handlers, routes, models & database.

Initially for the ORM I used prisma. But it seemed alienated and considering the time constraint I had selected, I switched to mongoose.

Then I created schema in zod for validation for the input. I liked its simplicity and the way it presents the errors. All the functions out of the box are very useful.

After than I created the documentation using swagger.Refered to some youtube videos. It is easy but a bit verbose.

Then comes the calendar integration part, which was the most challenging. I had to learn a lot about OAuth and how it works. This video explains it very well. Main problem that I was facing was to get the token from browser to server, this cosumed a lot of time.
Later I found that we can do OAuth from postman itself and was relieved.

Then using the calendar API, I function that was creating events in the calendar into the handler that booked the slot. When the first event was created in the calendar, it felt like a huge achievement. Later I added the google meet link to the event.

After that I created the docker file and created an image of the project.

At last, I deployed the project on Railway.
