Backend Task - Music Party!

Task Details
Build a simple stateless microservice for a Music app. The Music app allows listeners to play any
song of their choice from the playlist. The music app also has an admin interface that can add
songs to the music app.

Technologies
● You are free to use any language (Java, Nodejs, Python, etc ..)
● There are no restrictions on the frameworks/libraries to use. Choose whichever seems
best suited for the task.

API Details
1. A song should consist of meta information like singers, movies/albums linked, date of
release, etc.
2. Authentication endpoints:
a. Implement a role-based public authentication endpoint (Admin/Normal user).
Treat the endpoint as a mock authentication service and accept any
username/password.
b. The request body can contain an arbitrary username/password pair.
c. Return a signed JSON Web Token (JWT, https://jwt.io/) which can be used for
validation of subsequent requests.
3. Music REST API endpoints:
a. The JWT obtained in the “Authentication” endpoint will be attached to each
subsequent request. These endpoints should reject any request that has a
missing or invalid JWT token.
b. Create protected REST endpoints for the Admin user to Add/Delete songs in the
library
c. Create protected REST endpoints for the Normal/Admin user for the following
scenarios:
i. Can view a list of songs available in the library
ii. Can view a specific song along with all the details
iii. Can like/dislike the song
iv. Can view liked songs

Bonus: Extra points for attempting these


1. Host the backend app on Heroku, Firebase, Back4App, Vercel, etc
2. Adding music can be done on actual mp3 files by the admin user, which can be returned
as a stream while retrieving as a normal user
3. Implement all the above APIs as a GraphQL endpoint
4. Attach a data model if you are using NoSQL. Attach an ER Diagram if you are using
RDBMS.

Things we are interested in:


● Attention to detail and quality
● Modularity & readability of code
● Completeness of the APIs and database design

Important:
● Attach API documentation with a request which can be executed directly via Postman.
You can use Postam Collection, Swagger, etc for documentation. You do NOT need to
create a frontend UI for this app.
● Document steps for running the project in the local environment.
● We condemn plagiarism. Please maintain the dignity and originality of your work. If we
suspect any attempt towards copying, we will disqualify your submission. Also, do NOT
put your code on GitHub.
