pump-chat-client

library1.0.1jsnpmunverified

A WebSocket client library (v1.0.1) for connecting to pump.fun token chat rooms using the Socket.IO protocol. It provides real-time chat message streaming with automatic reconnection (exponential backoff), message history management, and an event-driven API via EventEmitter. Fully typed with TypeScript definitions. Key differentiator: abstracts pump.fun's proprietary socket.io protocol into a simple client interface for reading and sending chat messages. Suitable for integration into Solana-based trading bots and analytics dashboards.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

PumpChatClient

✓ import { PumpChatClient } from 'pump-chat-client'

✗ const PumpChatClient = require('pump-chat-client')

ESM-only; named export, not default export.

IMessage

✓ import { IMessage } from 'pump-chat-client'

TypeScript type, not a runtime value. Use for type annotations.

PumpChatClientOptions

✓ import { PumpChatClientOptions } from 'pump-chat-client'

TypeScript type for constructor options.

Connects to a pump.fun token chat room, listens for new messages, retrieves recent messages, and disconnects.

import { PumpChatClient } from 'pump-chat-client'; const client = new PumpChatClient({ roomId: 'YOUR_TOKEN_ADDRESS', username: 'my-bot', messageHistoryLimit: 50 }); client.on('connected', () => { console.log('Connected!'); }); client.on('message', (msg) => { console.log(`${msg.username}: ${msg.message}`); }); client.on('error', (err) => { console.error(err); }); client.connect(); // after some time const msgs = client.getMessages(5); console.log('Last messages:', msgs); client.disconnect();

Debug

Known issues

gotchasendMessage() requires authentication (valid pump.fun session cookies). Without auth, the call may fail silently or be ignored.

fix

Ensure the client is running in a browser context with active pump.fun session, or pass session tokens via headers (not yet supported).

affects: >=1.0.0

breakingThe library uses ESM imports. Using require() will cause a runtime error.

fix

Use import syntax or set type: module in package.json.

affects: >=1.0.0

deprecatedSocket.IO client v4 may change reconnection behavior; verify compatibility.

fix

Pin socket.io-client to the version compatible with the server (currently v4.x).

affects: >=1.0.0

Errors

Common errors & fixes

Cannot find module 'pump-chat-client' or its corresponding type declarations.

Package not installed or missing tsconfig.json configuration.

fix

npm install pump-chat-client && ensure tsconfig.json has moduleResolution: 'node'.

Uncaught TypeError: PumpChatClient is not a constructor

Using default import instead of named import.

fix

Correct to: import { PumpChatClient } from 'pump-chat-client'

Error: connect ECONNREFUSED <host>:<port>

pump.fun server not reachable or incorrect URL.

fix

Verify network connectivity and that the WebSocket URL is correct (handled internally).
