Day 5 deploys your chatbot to the internet with a public URL. You will use Railway for zero-config Node.js deployment.
Railway is the fastest way to deploy a Node.js app. Free tier is generous enough for a personal chatbot. Connect your repo, set environment variables, and it deploys automatically.
{
"scripts": {
"start": "node server.js"
}
}
# 1. Initialize git if you haven't git init git add . git commit -m "Initial chatbot" # 2. Create a .gitignore echo "node_modules/ .env" > .gitignore # 3. Push to GitHub git remote add origin your-repo-url git push -u origin main # 4. Go to railway.app # - New Project → Deploy from GitHub repo # - Select your repo # - Add environment variable: ANTHROPIC_API_KEY # - Railway auto-detects Node.js and deploys
Before sharing the URL publicly, add basic rate limiting and error handling:
// Wrap the API call in try/catch
app.post('/chat', async (req, res) => {
try {
const { message, sessionId } = req.body;
if (!message || message.length > 2000) {
return res.status(400).json({ error: 'Invalid message' });
}
// ... rest of your code ...
} catch (error) {
console.error('Error:', error.message);
res.status(500).json({
error: 'Something went wrong. Please try again.'
});
}
});
