This is the first time I have done anything with React in quite a while, I have been using VueJS for the past year. I am a little out of touch and had to read up on React Hooks.
When I saw the requirement for data synchronisation across browsers I immediately decided to use graphql with Apollo, this supports subscriptions over websockets. There are a couple of ways this could have been tackled
- Standard websockets which fires an event to update the data from the client
- Polling (probably the worse solution)
- Subscriptions
I am using a simple embedded database for persistence.
The Backend is in Node, normally I would have reached for PHP with Laravel, however the support for GraphQL and subscriptions is far more mature in Node.
I felt using Redux for state management in this application would be overkill and unnecessary. I have experience with redux in previous projects as well as Vuex.
Unfortunately I haven't any more time to dedicate to this test and have left out units tests. If I had more time I would consider refactoring the code into smaller units to make it easier for readability and testing.
make build
make startcd client && yarn && yarn build
cd ..
docker-compose build
docker-compose up -d
sleep 5
