-### How it Works/Using Ably
-
-#### Configuration
-
-[pages/\_app.js](pages/_app.js) is where the Ably SDK is configured:
-
-```js
-import { configureAbly } from "@ably-labs/react-hooks";
-
-const prefix = process.env.API_ROOT || "";
-const clientId =
- Math.random().toString(36).substring(2, 15) +
- Math.random().toString(36).substring(2, 15);
-
-configureAbly({
- authUrl: `${prefix}/api/createTokenRequest?clientId=${clientId}`,
- clientId: clientId,
-});
-
-function MyApp({ Component, pageProps }) {
- return ;
+### How it works
+
+#### Client provider
+
+[`app/ably-client-provider.tsx`](app/ably-client-provider.tsx) is a Client Component that creates the Ably Realtime client inside a `useEffect`, so no connection is attempted during SSR. It wraps the app in `AblyProvider` (and `ChannelProvider`) from `ably/react`, making the hooks available to child Client Components:
+
+```tsx
+"use client";
+
+import { useEffect, useState } from "react";
+import * as Ably from "ably";
+import { AblyProvider, ChannelProvider } from "ably/react";
+
+export default function AblyClientProvider({
+ children,
+}: {
+ children: React.ReactNode;
+}) {
+ const [clientId] = useState(
+ () =>
+ Math.random().toString(36).substring(2, 15) +
+ Math.random().toString(36).substring(2, 15),
+ );
+ const [client, setClient] = useState(null);
+
+ useEffect(() => {
+ const ably = new Ably.Realtime({
+ authUrl: `/api/createTokenRequest?clientId=${clientId}`,
+ clientId,
+ });
+ setClient(ably);
+ return () => {
+ ably.close();
+ };
+ }, [clientId]);
+
+ if (!client) return <>{children};
+
+ return (
+
+
+
+ {children}
+
+
+
+ );
}
-
-export default MyApp;
```
-`configureAbly` matches the method signature of the Ably SDK - and requires either a string or a [AblyClientOptions](https://ably.com/docs/api/realtime-sdk#client-options) object. You can use this configuration object to setup your [tokenAuthentication](https://ably.com/docs/core-features/authentication#token-authentication). If you want to use the usePresence function, you'll need to explicitly provide a `clientId`.
-
-You can do this anywhere in your code before the rest of the library is used.
+The client is authenticated via a [token request](https://ably.com/docs/core-features/authentication#token-authentication) served by a Route Handler at [`app/api/createTokenRequest/route.ts`](app/api/createTokenRequest/route.ts), so your `ABLY_API_KEY` is never exposed to the browser.
-#### useChannel (Publishing and Subscribing to Messages)
+#### useChannel (publishing and subscribing to messages)
The `useChannel` hook lets you subscribe to a channel and receive messages from it:
-```js
+```tsx
+"use client";
+
import { useState } from "react";
-import { useChannel } from "@ably-labs/react-hooks";
+import { useChannel } from "ably/react";
+import type * as Ably from "ably";
-export default function Home() {
- const [channel] = useChannel("your-channel", async (message) => {
+export default function ChatArea() {
+ const [messages, setMessages] = useState([]);
+
+ const { channel } = useChannel("some-channel-name", (message) => {
console.log("Received Ably message", message);
+ setMessages((prev) => [...prev, message]);
});
-}
-```
-
-Every time a message is sent to `your-channel` it will be logged to the console. You can do whatever you need to with those messages.
-
-##### Publishing a message
-The `channel` instance returned by `useChannel` can be used to send messages to the channel. It is a regular Ably JavaScript SDK `channel` instance.
+ // publish a message
+ const send = () => channel.publish("test-message", { text: "hello" });
-```javascript
-channel.publish("test-message", { text: "message text" });
+ return ;
+}
```
-#### usePresence
-
-The `usePresence` hook lets you subscribe to presence events on a channel - this will allow you to get notified when a user joins or leaves the channel. The presence data is automatically updated and your component re-rendered when presence changes:
-
-```js
-import { useState } from "react";
-import { usePresence } from "@ably-labs/react-hooks";
-
-export default function Home() {
- const [presenceData, updateStatus] = usePresence("your-channel-name");
-
- const presentClients = presenceData.map((msg, index) => (
-
- {msg.clientId}: {msg.data}
-
- ));
-
- return
{presentClients}
;
+#### usePresence and usePresenceListener
+
+`usePresence` enters presence and lets you update your presence data. `usePresenceListener` subscribes to presence changes on a channel:
+
+```tsx
+"use client";
+
+import { usePresence, usePresenceListener } from "ably/react";
+
+export default function Presence() {
+ const { updateStatus } = usePresence("your-channel-name");
+ const { presenceData } = usePresenceListener("your-channel-name");
+
+ return (
+ <>
+
+
+ {presenceData.map((msg, i) => (
+
+ {msg.clientId}: {String(msg.data ?? "")}
+
+ ))}
+
+
+ );
}
```
