Node.js is a powerful JavaScript runtime for building fast, scalable server-side applications. This recipe provides a complete Node.js development environment for building modern web applications, APIs, and microservices.
Every EasyEnv recipe spins up in seconds on a real Linux VM-not a stripped-down sandbox. The Node.js recipe is provisioned by an open Ansible role, so the machine that boots for you is reproducible, inspectable, and matches what you would get in production.
$ easyenv workspace create --recipe nodejs_devenv --name nodejs_devenv-demo

Workspace ready in ~45s
$ easyenv workspace ssh nodejs_devenv-demo
Connected. You're on the machine.A Node.js development workspace with current LTS Node, npm, and the build tools needed for native modules. Use it for backend services, CLIs, full-stack JavaScript/TypeScript apps, or for interview sessions where the candidate needs a real terminal and a real filesystem.
Because EasyEnv is a real Linux machine, you can also install pnpm, bun, deno, or any other runtime alongside Node without conflict-and the workspace persists across sessions so your `node_modules` stays warm.
Questions hiring teams use to evaluate engineers on Node.js. Want to ask them on a real, production-like environment? Try EasyEnv for technical interviews.
Explain the event loop. How is `setImmediate` different from `setTimeout(fn, 0)`?
What is the difference between `process.nextTick` and a microtask?
How do you handle CPU-bound work in a Node service without blocking the loop?
Describe the difference between CommonJS and ES modules in Node.
How does Node's cluster module work, and when would you use it vs. a process manager?
Learn TypeScript end to end. Types, interfaces, generics, classes, modules, utility and mapped types, declaration files, and the compiler.
Stop guessing from resumes. Drop candidates into a real Node.js workspace, watch them debug, deploy and operate it, score the result automatically, and replay the session. We also evaluate how they work with AI.
