fivem-nui-react-lib

A (very opinionated) set of tools for using FiveM NUI events in React

example

https://github.com/jfrader/fivem-nui-react-boilerplate

usage

install

npm install --save fivem-nui-react-lib

Use Provider

import { NuiProvider } from "fivem-nui-react-lib";

function App() {
    return (
        <NuiProvider resource="my-resource-name">
            <div>This is my app</div>
        </NuiProvider>
    );
}

useNuiEvent

This library receives the following schema on NUI events

{
  app: 'app-name', // can be always the same or change to differenciate events better on the UI
  event: 'event-name', // the actual event name which is sent to NUI
  data: 'response' // the response which will be handled from the UI
}

Receive events from client and set your state

// UI
import { useNuiEvent } from "fivem-nui-react-lib";

function MyComponent() {
    const [myState, setMyState] = useState(false);
    useNuiEvent("app-name", "method-name", setMyState);
}

// CLIENT
sendNuiMessage(
    JSON.stringify({
        app: "app-name",
        event: "event-name",
        data: true, // myState will be set as true in this example
    })
);

useNuiRequest

Send requests to client

// UI
import { useNuiRequest } from "fivem-nui-react-lib";

function MyComponent() {
    const { send } = useNuiRequest();
    send("method-name", { myArgument: "isAwesome" });
}

// CLIENT
RegisterNuiCallbackType(`__cfx_nui:myEvent`);
on(`__cfx_nui:myEvent`, (data, cb) => {
    // Use the arguments
    emitNet("myEvent", { input: data.myArgument });
    // Callback to prevent errors
    cb();
});

useNuiCallback

Make a callback to "myEvent" by sending back "myEventSuccess" or "myEventError" from the client

// UI
import { useNuiCallback } from "fivem-nui-react-lib";

function MyComponent() {
    const [myState, setMyState] = useState(null);
    const [error, setError] = useState(null);
    const [fetchMyMethod, { loading }] = useNuiCallback("app-name", "myEvent", setMyState, setError);

    useEffect(() => {
        fetchMyMethod({ argument: 1 });
    }, [fetchMyMethod]);
}

// CLIENT
RegisterNuiCallbackType(`__cfx_nui:myEvent`);
on(`__cfx_nui:myEvent`, (data, cb) => {
    // emit some event to the server:
    emitNet("myEvent", { input: data });
    // callback so you prevent errors
    cb();
});

// ... on success
sendNuiMessage(
    JSON.stringify({
        app: "app-name",
        event: "event:success",
        data: true,
    })
);

// ... on error
sendNuiMessage(
    JSON.stringify({
        app: "app-name",
        event: "event:failed",
        data: true,
    })
);

The example above will request myEvent to the client and be in loading state until client sends back either myEventSuccess or myEventError. After one of those are received, the handlers will be executed (setMyState if success, setError if errored). If no event is received after the timeout time, it will throw as timeout error.
