Creating a Reusable React Hook for OpenClaw Rating API Edge WebSocket Streams

You can create a reusable React hook called useOpenClawRatings that abstracts the Edge WebSocket connection, automatically handles reconnection, parses rating messages, and plugs into any React state‑management solution.

Creating a Reusable React Hook for OpenClaw Rating API Edge WebSocket Streams

1. Introduction

Real‑time dashboards and rating‑driven UI components are becoming core features of modern SaaS products. A well‑engineered hook not only reduces boilerplate but also guarantees a consistent reconnection strategy across the entire codebase. This guide walks you through building useOpenClawRatings from scratch, integrating it with useState, Redux, or Zustand, and deploying the solution on the OpenClaw hosting guide.

Why reusable hooks matter

• Encapsulation – keep WebSocket logic out of UI components.
• Testability – isolated hook can be unit‑tested with mock sockets.
• Consistency – a single reconnection policy prevents duplicate bugs.

Overview of OpenClaw Rating API Edge WebSocket

The Edge WebSocket endpoint streams JSON payloads such as:

{
  "type": "rating",
  "id": "movie-123",
  "score": 4.7,
  "timestamp": "2024-11-02T14:23:11Z"
}

Each message represents a live rating update for a specific entity (movie, product, etc.). The connection is secured via wss:// and requires an API key passed as a query parameter.

2. Setting up the WebSocket connection

Required dependencies

Start with a fresh React project (Create‑React‑App, Vite, or Next.js). Install only what you need:

npm install react@^18.2.0

If you plan to use Redux or Zustand, add them now:

# Redux
npm install @reduxjs/toolkit react-redux

# Zustand
npm install zustand

Basic connection code

Below is a minimal WebSocket wrapper that opens a connection and forwards raw messages to a callback.

class EdgeSocket {
  constructor(url, onMessage, onError) {
    this.url = url;
    this.onMessage = onMessage;
    this.onError = onError;
    this.socket = null;
    this.connect();
  }

  connect() {
    this.socket = new WebSocket(this.url);
    this.socket.addEventListener('open', () => console.log('WebSocket opened'));
    this.socket.addEventListener('message', e => this.onMessage(e.data));
    this.socket.addEventListener('error', this.onError);
    this.socket.addEventListener('close', () => {
      console.warn('WebSocket closed – attempting reconnection');
      setTimeout(() => this.connect(), 2000);
    });
  }

  close() {
    this.socket && this.socket.close();
  }
}

3. Building the useOpenClawRatings hook

Hook signature and return values

The hook returns three items:

• ratings – an array of parsed rating objects.
• status – connection status (connecting, open, error).
• reset – a function to manually reconnect.

Implementation

import { useEffect, useRef, useState, useCallback } from 'react';

/**
 * useOpenClawRatings – subscribes to the Edge WebSocket and returns live ratings.
 *
 * @param {string} apiKey   Your OpenClaw API key.
 * @param {string} [entity] Optional filter (e.g., "movie", "product").
 * @returns {{ratings: Array, status: string, reset: Function}}
 */
export function useOpenClawRatings(apiKey, entity) {
  const [ratings, setRatings] = useState([]);
  const [status, setStatus] = useState('connecting');
  const socketRef = useRef(null);
  const reconnectAttempts = useRef(0);
  const maxBackoff = 30000; // 30 seconds

  const parseMessage = useCallback(data => {
    try {
      const msg = JSON.parse(data);
      if (msg.type === 'rating' && (!entity || msg.id.startsWith(entity))) {
        setRatings(prev => [...prev, msg]);
      }
    } catch (e) {
      console.error('Failed to parse rating message', e);
    }
  }, [entity]);

  const connect = useCallback(() => {
    const url = `wss://edge.openclaw.io/ratings?apiKey=${apiKey}`;
    socketRef.current = new WebSocket(url);

    socketRef.current.addEventListener('open', () => {
      setStatus('open');
      reconnectAttempts.current = 0;
    });

    socketRef.current.addEventListener('message', e => parseMessage(e.data));

    socketRef.current.addEventListener('error', () => {
      setStatus('error');
    });

    socketRef.current.addEventListener('close', () => {
      setStatus('connecting');
      // Exponential back‑off reconnection
      const delay = Math.min(1000 * 2 ** reconnectAttempts.current, maxBackoff);
      reconnectAttempts.current += 1;
      setTimeout(connect, delay);
    });
  }, [apiKey, parseMessage]);

  // Initial connection
  useEffect(() => {
    connect();
    return () => {
      socketRef.current && socketRef.current.close();
    };
  }, [connect]);

  // Manual reset hook
  const reset = useCallback(() => {
    socketRef.current && socketRef.current.close();
    setRatings([]);
    connect();
  }, [connect]);

  return { ratings, status, reset };
}

Handling reconnection logic

The hook uses an exponential back‑off strategy (1 s, 2 s, 4 s … up to 30 s). This prevents hammering the Edge server while still providing fast recovery for transient network glitches.

Parsing rating messages

Only messages with type: "rating" are kept. If an entity filter is supplied, the hook discards unrelated IDs, keeping the state lean.

Integration with state‑management patterns

Using useState (default)

The hook already returns a local ratings array managed by useState. Most components can consume it directly.

Redux Toolkit

Dispatch the parsed rating to a slice:

// ratingSlice.js
import { createSlice } from '@reduxjs/toolkit';

export const ratingSlice = createSlice({
  name: 'ratings',
  initialState: [],
  reducers: {
    addRating: (state, action) => {
      state.push(action.payload);
    },
    resetRatings: () => []
  }
});

export const { addRating, resetRatings } = ratingSlice.actions;
export default ratingSlice.reducer;

// In a component
import { useOpenClawRatings } from './useOpenClawRatings';
import { useDispatch } from 'react-redux';
import { addRating, resetRatings } from './ratingSlice';

export function RatingConsumer({ apiKey }) {
  const dispatch = useDispatch();
  const { status, reset } = useOpenClawRatings(apiKey);

  // Hook inside the slice
  useEffect(() => {
    const handler = data => dispatch(addRating(data));
    // You could modify useOpenClawRatings to accept a custom onMessage
  }, [dispatch]);

  return 
{status}
;
}

Zustand

Zustand’s minimal API makes it perfect for real‑time streams:

// store.js
import create from 'zustand';

export const useRatingStore = create(set => ({
  ratings: [],
  addRating: rating => set(state => ({ ratings: [...state.ratings, rating] })),
  reset: () => set({ ratings: [] })
}));

// Component
import { useOpenClawRatings } from './useOpenClawRatings';
import { useRatingStore } from './store';

export function RatingZustand({ apiKey }) {
  const addRating = useRatingStore(state => state.addRating);
  const { status, reset } = useOpenClawRatings(apiKey);

  useEffect(() => {
    const handler = data => addRating(data);
    // Hook can be extended to accept handler
  }, [addRating]);

  return 
WebSocket status: {status}
;
}

4. Practical example: Using the hook in a component

Below is a complete functional component that displays live ratings for a movie catalog. It uses the default useState integration, Tailwind styling, and provides a manual reconnect button.

import React from 'react';
import { useOpenClawRatings } from './useOpenClawRatings';

export default function LiveMovieRatings({ apiKey }) {
  const { ratings, status, reset } = useOpenClawRatings(apiKey, 'movie');

  return (
    <div className="max-w-2xl mx-auto p-4">
      <h2 className="text-2xl font-semibold mb-4">Live Movie Ratings</h2>

      <div className="flex items-center mb-2">
        <span className="font-medium mr-2">WebSocket:</span>
        <span
          className={`
            px-2 py-1 rounded ${
              status === 'open' ? 'bg-green-200' : 'bg-yellow-200'
            }`}>
          {status}
        </span>
        <button
          onClick={reset}
          className="ml-auto bg-blue-600 text-white px-3 py-1 rounded hover:bg-blue-700 transition">
          Reconnect
        </button>
      </div>

      <ul className="space-y-2">
        {ratings.slice(-10).reverse().map(rating => (
          <li key={rating.id + rating.timestamp} className="p-2 border rounded bg-gray-50">
            <strong className="mr-2">{rating.id}</strong>
            scored <span className="font-bold text-indigo-600">{rating.score}</span>
            <span className="text-sm text-gray-500 ml-2">
              ({new Date(rating.timestamp).toLocaleTimeString()})
            </span>
          </li>
        ))}
      </ul>
    </div>
  );
}

The component renders the most recent ten ratings, updates instantly as new messages arrive, and lets the user force a reconnection if needed.

5. Best‑practice tips

Connection cleanup

• Always close the socket in a useEffect cleanup to avoid memory leaks.
• When a component unmounts, call socketRef.current?.close().

Error handling & back‑off strategies

• Log errors to a monitoring service (e.g., Sentry) for production visibility.
• Cap the exponential back‑off at a reasonable maximum (30 s works well).
• Consider a jitter algorithm to spread reconnection attempts across clients.

Security considerations

• Never hard‑code the API key; use environment variables or a secure vault.
• Validate incoming JSON against a schema (e.g., zod) before updating state.
• Prefer wss:// and enforce CORS policies on the Edge server.

Testing the hook

Use jest with mock-socket to simulate WebSocket events. Verify that:

• Ratings are appended correctly.
• Reconnection occurs after a forced close.
• Back‑off delays respect the exponential formula.

Performance & scalability

• Throttle UI updates with requestAnimationFrame if the stream exceeds 30 msg/s.
• Store only the last N messages (e.g., 500) to keep memory usage low.
• Offload heavy parsing to a Web Worker for ultra‑high‑throughput scenarios.
