Replit Deploy Integration

Overview

Deploy applications on Replit's hosting platform. Three deployment types: Static (free, frontend-only), Autoscale (scales to zero, pay per request), and Reserved VM (always-on, fixed cost). Includes custom domain setup, health checks, rollbacks, and deployment monitoring.

Prerequisites

Replit Core, Pro, or Teams plan (deployment access)
Application working in Workspace ("Run" button)
Custom domain (optional) with DNS access

Deployment Types

Type	Best For	Pricing	Scale
Static	HTML/CSS/JS frontends	Free	CDN-backed, auto-cached
Autoscale	Variable traffic APIs	Per request	0 to N instances
Reserved VM	Always-on services	$0.20+/day	Fixed resources

Instructions

Step 1: Configure `.replit` for Deployment

Workspace Secrets auto-sync to Deployments (2025+).

1. Click lock icon (Secrets) in sidebar
2. Add production secrets:
   - DATABASE_URL (auto-populated by Replit PostgreSQL)
   - API_KEY, JWT_SECRET, etc.
3. Verify in Deployment Settings > Environment Variables

// src/routes/health.ts
import { Router } from 'express';
import { pool } from '../services/db';

const router = Router();

router.get('/health', async (req, res) => {
  const checks: Record<string, any> = {
    status: 'ok',
    uptime: process.uptime(),
    timestamp: new Date().toISOString(),
  };

  // Check database if configured
  if (process.env.DATABASE_URL) {
    try {
      await pool.query('SELECT 1');
      checks.database = 'connected';
    } catch {
      checks.database = 'disconnected';
      checks.status = 'degraded';
    }
  }

  // Replit-specific metadata
  checks.repl = process.env.REPL_SLUG;
  checks.region = process.env.REPLIT_DEPLOYMENT_REGION;

  const statusCode = checks.status === 'ok' ? 200 : 503;
  res.status(statusCode).json(checks);
});

export default router;

Via Replit UI:
1. Click "Deploy" button in the top bar
2. Select deployment type:
   - Static: for frontend-only apps
   - Autoscale: scales to zero when idle
   - Reserved VM: always-on, choose machine size
3. Configure machine size (Autoscale/VM):
   - 0.25 vCPU / 512 MB — lightweight APIs
   - 0.5 vCPU / 1 GB — standard web apps
   - 2 vCPU / 4 GB — compute-heavy apps
   - 4+ vCPU / 8-16 GB — production workloads
4. Click "Deploy"
5. Monitor build output in the deploy console

1. Go to Deployment Settings > Custom Domain
2. Enter your domain: app.example.com
3. Add DNS record at your registrar:
   Type: CNAME
   Name: app
   Value: your-repl-slug.replit.app
4. Wait for SSL auto-provisioning (1-5 minutes)
5. Verify:

# Verify DNS
dig app.example.com CNAME

# Verify SSL
curl -I https://app.example.com

# Verify health
curl -sf https://app.example.com/health | jq .

1. Go to Deployment Settings > History
2. View list of past deployments with timestamps
3. Click "Rollback" on the desired version
4. Deployment reverts immediately
5. Verify health endpoint after rollback

set -euo pipefail
DEPLOY_URL="https://your-app.replit.app"

echo "=== Deployment Verification ==="

# Health check
echo -n "Health: "
curl -sf "$DEPLOY_URL/health" | jq -r '.status'

# Response time
echo -n "Response time: "
curl -s -o /dev/null -w "%{time_total}s\n" "$DEPLOY_URL/"

# SSL certificate
echo -n "SSL: "
curl -sI "$DEPLOY_URL" | grep -i "strict-transport" && echo "OK" || echo "Missing HSTS"

# Autoscale cold start test
echo "Cold start test: wait 10 min, then curl again"

Issue	Cause	Solution
Deploy fails at build	Dependency error	Test `npm ci && npm run build` locally first
503 after deploy	App crashes on start	Check deployment logs, verify secrets
Port mismatch	Not using PORT env	`app.listen(process.env.PORT \|\| 3000)`
Cold start slow (>10s)	Heavy imports on startup	Lazy-load non-critical modules
Custom domain 404	DNS not propagated	Wait, or verify CNAME record
SSL not provisioning	Wrong DNS record	Must be CNAME to `.replit.app`
