Kodify Technical Test
Getting started
Fork the repo into your own github account and clone it onto your development environment. Make sure you have docker and docker compose installed.
You can start the project by running the command below in your terminal at the root of the project. This will start 4 containers, the client side React application, the server side Express application, a mongodb instance and a script to seed the database with some dummy data.
docker-compose up
The codebase
In the packages you'll see a React App that contains a video player component and the parent App component. On render the App calls our server with the videoId of 12345 returning a Video with it's sources. We then send our Video to the token endpoint to sign it's sources. We update the players props, which in turn causes the player to load the video, enabling it to be played.
Tasks
We would like you to complete the following tasks:
Push each task as a commit to the forked repo. Please submit the repo to the recruiter via email.
Task 1
Troubleshoot and fix the /video/12345 request in the App component.
Task 2
Create the endpoint for the url signing. The hash should be generated using the instructions below and appended to each source url.
For the cdn to accept the request, the url needs to contain a query param called token that is equal to a md5 hex encoded hash of the uri with a secret query param set to the following key: U5e0IskwtIfA.
For example http://www.cdn.com/big_buck_bunny.mp4 would require a hash encoding of /big_buck_bunny.mp4?secret=U5e0IskwtIfA resulting in the following call to the cdn: http://www.cdn.com/big_buck_bunny.mp4?token=0173c224ab73ad8ac23fb0f08155d83d
Task 3
Refactor the /video/:videoId controller on the server to decouple the video viewed tracking.
