Question 1

How to set up streams with react-native-tcp?

Accepted Answer

You need to install rn-nodeify as a dev dependency and run it to hack in stream, process, and util modules, as per the README. This is required due to React Native packager limitations for proper data handling.

Question 2

Does react-native-tcp support SSL/TLS for secure connections?

Accepted Answer

No, it only implements raw TCP sockets based on Node.js's net API. For secure communication, you must implement encryption manually or use additional modules, as SSL is not included.

Question 3

react-native-tcp vs react-native-udp: which should I choose?

Accepted Answer

Choose react-native-tcp for reliable, connection-oriented communication like custom protocols, and react-native-udp for faster, connectionless datagrams. Both are forked from similar codebases, so the decision depends on your use case.

Question 4

Is react-native-tcp compatible with Expo managed workflow?

Accepted Answer

No, because it requires native linking and dependencies like rn-nodeify, which are not supported in Expo's managed workflow. You must use bare React Native or eject from Expo.

Question 5

How to handle errors when using react-native-tcp?

Accepted Answer

Follow Node.js net API patterns, such as listening for 'error' events on sockets and servers. The module aims to be a drop-in replacement, so refer to Node.js documentation for error handling best practices.

Question 6

What are the performance implications of using react-native-tcp?

Accepted Answer

Performance may be slower than native sockets due to the JavaScript-Native bridge in React Native. For high-throughput applications, test thoroughly and consider the overhead of data serialization between layers.
