curl --location --request POST 'http://localhost:5006/api/audio/audio-files' \
--form 'audioFile=@"/C:/Users/test/example.mp3"'

response:

{
    "fileId": "68307dfa-7227-48a3-a825-88e506279deb",
    "name": "example.mp3"
}

Save metadata for file using given file-id

curl --location --request POST 'http://localhost:5006/api/audio/' \
--header 'Content-Type: application/json' \
--data-raw '{
    "FileId" : "68307dfa-7227-48a3-a825-88e506279deb",
    "Name" : "example.mp3",
    "Length" : 1243532,

}'

response:

{
    "id": "05773a0c-0f52-4385-31f5-08da04f8b068"
}

this is an id to fetch metadata

Logcast recruitment assignment

Hi! The purpose of this assignment is to get familiar with the logcast stack and to solve a realistic use case.

The task at hand

The task at hand consists in writing code in all parts of the stack:

1. Frontend: In the Audio component
   1. Implement an upload function which accepts an audio file
   2. Implement a simple media player to playback audio from the backend
2. Backend: Start in the Audio controller
   1. Implement support in the API to accept an audio file and corresponding metadata
   2. Implement support to fetch audio files and corresponding metadata
3. Database (Using Entity Framework):
   1. Implement relevant entities, repositories and dependencies
   2. Database changes should be version controlled using ef core migrations
4. Filestorage
   1. Store files conveniently
5. Write a short description of your solution

Prerequisits

• .NET 5.0
• Node.js
• SQL server

Optional

• Docker

IDEs

Obviously, you are allowed to use any IDE you like but we tend to use:

• Visual Studio
• Jetbrains Rider
• Visual Code
• SQL Management Studio

What we like

• Clean, effective and self-documenting code
• Test-coverage (Unit tests are enough, but an example of some kind of end-to-end component test is a big plus)
• Inversion of control
• Unit of work

DOs and DONTs

• Feel free to use any third party libraries (nuget or npm) you see fitting.
• Dont go all the way implementing everything production-ready. A nice proof of concept of the above task is enough as long you are ready to discuss possible improvements and/or alternative solutions.
