Node.js
What is Node.js?
Node.js is a JavaScript runtime environment that allows developers to execute JavaScript code outside of a web browser. This enables developers to build server-side applications, implement business logic, and create backend services using JavaScript—a language traditionally used only for client-side web development.
Why does Node.js matter for AI product development?
Node.js has become an important tool for building AI-powered products because it enables developers to orchestrate API calls, manage business logic, and run production code in cloud environments like AWS. For teams building AI features, Node.js provides a way to connect frontend experiences to AI APIs, handle data processing, and manage the complex workflows that AI products require.
The runtime environment makes it possible to use the same programming language (JavaScript) across both frontend and backend development, which can simplify product development and reduce context switching for teams.
What do you need to know about Node.js for Claude Code?
For tools like Claude Code, Node.js serves as a required runtime environment that must be installed before the application can run. This is a one-time setup requirement—once Node.js is installed on your computer, it provides the foundation for running Node.js-based applications.
Setting up Node.js is straightforward: visit Nodejs.org, download the installer, and follow the installation steps. Once complete, you can run Node.js applications without thinking about the runtime environment again.
