Question 1

How do I set up Phoenix Channels with React for real-time updates?

Accepted Answer

This project demonstrates using Phoenix Channels on the Elixir server and connecting via WebSockets in the React client. You'll need to handle event broadcasting with GenEvent and integrate updates into React's lifecycle, but note the complex setup involving Redis and multiple build steps.

Question 2

Is Flux still a good choice compared to Redux for state management?

Accepted Answer

Flux introduced unidirectional data flow but has been largely replaced by Redux due to its simpler API and middleware support. This project uses Flux for learning purposes, but for new projects, Redux or Context API might be more practical.

Question 3

What's the difference between Phoenix Channels and Socket.IO for real-time apps?

Accepted Answer

Phoenix Channels are built into the Phoenix framework and leverage Elixir's concurrency for robust real-time features, while Socket.IO is framework-agnostic but may not integrate as tightly with Elixir's event system. This project shows Phoenix's native advantages for Elixir backends.

Question 4

How to handle server-sent events in Elixir with a React frontend?

Accepted Answer

This project uses GenEvent to manage and broadcast events from the Elixir server, which are pushed to clients via Phoenix Channels. React components listen to these updates through Flux stores and re-render accordingly.

Question 5

Can I use this codebase for a production application?

Accepted Answer

No, it's not recommended as the project is experimental and uses outdated tools like 6to5 and Flux. For production, consider more mature solutions like Phoenix LiveView or updated React state management with modern bundlers.

Question 6

What are alternatives to 6to5 for transpiling JavaScript in Elixir projects?

Accepted Answer

6to5 was rebranded to Babel, so modern projects should use Babel for ES6+ transpilation. Additionally, tools like Webpack or Parcel are now more common than Browserify for bundling in React applications.
