Comprehensive deployment platform guide covering Vercel (edge-first), Railway (container-first), and Convex (real-time backend).

Quick Platform Selection

When to Use Each Platform

Vercel - Edge-First Deployment:

• Next.js applications with SSR/SSG
• Global CDN distribution required
• Sub-50ms edge latency critical
• Preview deployments for team collaboration
• Managed storage needs (KV, Blob, Postgres)

Railway - Container-First Deployment:

• Full-stack containerized applications
• Custom runtime environments
• Multi-service architectures
• Persistent volume storage
• WebSocket/gRPC long-lived connections

Convex - Real-Time Backend:

• Collaborative real-time applications
• Reactive data synchronization
• TypeScript-first backend needs
• Optimistic UI updates
• Document-oriented data models

Decision Guide

By Application Type

Web Applications (Frontend + API):

• Next.js → Vercel (optimal integration)
• React/Vue with custom API → Railway (flexible)
• Real-time collaborative → Convex + Vercel

Mobile Backends:

• REST/GraphQL → Railway (stable connections)
• Real-time sync → Convex (reactive queries)
• Edge API → Vercel (global latency)

Full-Stack Monoliths:

• Containerized → Railway (Docker support)
• Serverless → Vercel (Next.js API routes)
• Real-time → Convex (built-in reactivity)

By Infrastructure Needs

Compute Requirements:

• Edge compute → Vercel (30+ edge locations)
• Custom runtimes → Railway (Docker flexibility)
• Serverless TypeScript → Convex (managed runtime)

Storage Requirements:

• Redis/KV → Vercel KV or Railway
• PostgreSQL → Vercel Postgres or Railway
• File storage → Vercel Blob or Railway volumes
• Document DB → Convex (built-in)

Networking Requirements:

• CDN distribution → Vercel (built-in)
• Private networking → Railway (service mesh)
• Real-time WebSocket → Convex (built-in) or Railway

Common Deployment Patterns

Pattern 1: Next.js with Database

Stack: Vercel + Vercel Postgres/KV

Setup:

1. Deploy Next.js app to Vercel
2. Provision Vercel Postgres for database

5. Connect Convex client

Best For: Rapid prototyping, startups, real-time web apps

Essential Configuration

Vercel Quick Start

vercel.json:

{
  "$schema": "https://openapi.vercel.sh/vercel.json",
  "framework": "nextjs",
  "regions": ["iad1", "sfo1", "fra1"],
  "functions": {
    "app/api/**/*.ts": {
      "memory": 1024,
      "maxDuration": 10
    }
  }
}

Edge Function:

export const runtime = "edge"
export const preferredRegion = ["iad1", "sfo1"]

export async function GET(request: Request) {
  const country = request.geo?.country || "Unknown"
  return Response.json({ country })
}

Railway Quick Start

railway.toml:

[build]
builder = "DOCKERFILE"
dockerfilePath = "Dockerfile"

[deploy]
healthcheckPath = "/health"
healthcheckTimeout = 100
restartPolicyType = "ON_FAILURE"
numReplicas = 2

[deploy.resources]
memory = "2GB"
cpu = "2.0"

Multi-Stage Dockerfile:

# Builder stage
FROM node:20-alpine AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci
COPY . .
RUN npm run build

# Runner stage
FROM node:20-alpine
WORKDIR /app
ENV NODE_ENV=production
RUN addgroup -g 1001 -S nodejs && adduser -S appuser -u 1001
COPY --from=builder /app/node_modules ./node_modules
COPY --from=builder /app/dist ./dist
USER appuser
EXPOSE 3000
CMD ["node", "dist/main.js"]

Convex Quick Start

convex/schema.ts:

import { defineSchema, defineTable } from "convex/server"
import { v } from "convex/values"

export default defineSchema({
  messages: defineTable({
    text: v.string(),
    userId: v.id("users"),
    timestamp: v.number(),
  })
    .index("by_timestamp", ["timestamp"])
    .searchIndex("search_text", {
      searchField: "text",
      filterFields: ["userId"],
    }),
})

React Integration:

import { useQuery, useMutation } from "convex/react"
import { api } from "../convex/_generated/api"

export function Messages() {
  const messages = useQuery(api.messages.list)
  const sendMessage = useMutation(api.messages.send)

  if (!messages) return <div>Loading...</div>

  return (
    <div>
      {messages.map((msg) => (
        <div key={msg._id}>{msg.text}</div>
      ))}
    </div>
  )
}

Advanced Patterns

Blue-Green Deployment (Vercel)

Deploy new version, test on preview URL, then switch production alias using Vercel SDK for zero-downtime releases.

Multi-Region (Railway)

Configure deployment regions in railway.toml:

[deploy.regions]
name = "us-west"
replicas = 2

[[deploy.regions]]
name = "eu-central"
replicas = 1

Optimistic Updates (Convex)

const sendMessage = useMutation(api.messages.send)

const handleSend = (text: string) => {
  sendMessage({ text })
    .then(() => console.log("Sent"))
    .catch(() => console.log("Failed, rolled back"))
}
