What is Node.js?

  • A JavaScript runtime for backends and scripting (including frontend builds)
  • Requires a single JavaScript entry point to execute


  • Code can be modularized using either CommonJS or ECMAScript Modules (ESM)
  • Uses a manifest file to reference dependencies and import them into code
~ node my_app.js

How is Node.js built?

  • Built on top of V8, Google's open source project that powers Chrome's JavaScript runtime
  • The binary is written with both JavaScript and C++

  • Node is built with additional libraries, such as OpenSSL and libuv, that are supplemental to core functionality
