Hooks
Using hooks, you can define a WebSocket server that works across runtimes with the same syntax.
Crossws provides a cross-platform API to define WebSocket servers. An implementation with these hooks works across runtimes without needing you to go into details of each of them. You only define the life-cycle hooks that you only need.
Using
defineHooks() wrapper is optional and for type support and code auto completion.import { defineHooks } from "crossws";
const hooks = defineHooks({
upgrade(req) {
console.log(`[ws] upgrading ${req.url}...`)
return {
headers: {}
}
},
open(peer) {
console.log(`[ws] open: ${peer}`);
},
message(peer, message) {
console.log("[ws] message", peer, message);
if (message.text().includes("ping")) {
peer.send("pong");
}
},
close(peer, event) {
console.log("[ws] close", peer, event);
},
error(peer, error) {
console.log("[ws] error", peer, error);
},
});
