#Technetium
- In this project we will work feature wise. That means we pick one object like user, book, blog, etc at a time. We work through it's feature. The steps would be:
- We create it's model.
- We build it's APIs.
- We test these APIs.
- We deploy these APIs.
- We integrate these APIs with frontend.
- We will repeat steps from Step 1 to Step 5 for each feature in this project.
- This project is divided into 4 features namely User, Product, Cart and Order. You need to work on a single feature at a time. Once that is completed as per above mentioned steps. You will be instructed to move to next Feature.
- In this project we are changing how we send token with a request. Instead of using a custom header key like x-api-key, you need to use Authorization header and send the JWT token as Bearer token.
- Create a group database
groupXDatabase
. You can clean the db you previously used and resue that. - This time each group should have a single git branch. Branch name should follow the naming convention
project/productsManagement
- Follow the naming conventions exactly as instructed.
