codemend

Catch production errors and get AI-powered fixes. Works with Node.js, Express, and React Native.

codemend.ai

Install

npm install codemend

Node.js

const codemend = require('codemend');

codemend.init({ apiKey: 'ah_your_key_here' });

// Catch all uncaught errors automatically
codemend.setupProcessHandlers();

// Or capture errors manually
try {
  riskyFunction();
} catch (err) {
  codemend.captureError(err);
}

Express

const express = require('express');
const codemend = require('codemend');

const app = express();

codemend.init({ apiKey: 'ah_your_key_here' });

// Your routes...
app.get('/', (req, res) => res.send('Hello'));

// Add as the LAST middleware
app.use(codemend.expressErrorHandler());

app.listen(3000);

React Native

import codemend from 'codemend/react-native';

// In your App.tsx, before rendering
codemend.init({ apiKey: 'ah_your_key_here' });
codemend.setupErrorHandler();

export default function App() {
  // Your app...
}

Options

codemend.init({
  apiKey: 'ah_...',           // Required — from your Codemend dashboard
  appUrl: 'https://...',      // Optional — defaults to https://codemend.ai
  enabled: true,              // Optional — defaults to true in production
  debug: false,               // Optional — log when errors are sent
  metadata: { env: 'staging' } // Optional — extra data sent with every error
});

How it works

1. Your app hits an error
2. Codemend sends it to your dashboard
3. AI reads your code and writes a fix
4. You get a Slack/email notification with the fix
5. One click to create a pull request
