Question 1

How to setup isomorphic relay router with Express.js?

Accepted Answer

Follow the server-side code in the README: use `match` from react-router to get renderProps, then call `IsomorphicRouter.prepareData` with the network layer, render with `IsomorphicRouter.render`, and send the output. Ensure you have the correct routes and network layer configured.

Question 2

Isomorphic relay router vs Next.js for GraphQL SSR?

Accepted Answer

Isomorphic relay router is specifically for Relay and React Router, offering fine-grained control, while Next.js has built-in SSR and supports various data fetching methods but might not integrate as tightly with Relay. Choose based on your existing stack and need for customization.

Question 3

Does isomorphic relay router work with Relay Modern?

Accepted Answer

The library is designed for the classic Relay (likely Relay Classic), as it uses `Relay.DefaultNetworkLayer`. It may not be compatible with Relay Modern out of the box, requiring adaptations or updates.

Question 4

How to handle errors in isomorphic relay router?

Accepted Answer

Error handling is shown in the server code with `next(error)` and `catch(next)`. You need to implement proper error boundaries and network error handling in both server and client configurations.

Question 5

Can I use isomorphic relay router with TypeScript?

Accepted Answer

There's no official TypeScript support mentioned in the README. You would need to find or create type definitions, which might be limited due to the library's niche usage.

Question 6

Performance impact of isomorphic relay router?

Accepted Answer

It improves initial load performance by rendering HTML on the server, but adds complexity to the build and deployment process. Ensure efficient GraphQL queries and network layers to avoid bottlenecks.
