Node.js Website Migration Guide

Node.js migrations are high-variance because the application might be a static build, an SSR app, an API, a worker, or a custom service tied to databases and queues. Migration Monkey rates Node.js as a higher-touch profile so the estimate reflects runtime and deployment risk.

What the analyzer looks for

The source agent can identify package.json, declared Node engine requirements, file size, top-heavy directories, and runtime limits. Operators still need to verify build commands, environment variables, process manager, and service bindings.

Migration checklist

• Record Node version, package manager, lockfile, and build command.
• Export environment variables without committing secrets.
• Identify database, Redis, queue, object storage, and third-party API dependencies.
• Confirm process manager: PM2, systemd, Docker, cPanel Node.js, or platform runtime.
• Test health checks and logs before switching DNS.

Why custom Node.js costs more

File size alone does not predict Node.js migration work. Build systems, native modules, process managers, websockets, queues, and external databases can make a small app more complex than a large static WordPress site.
