Node Fetch Built-in

With Node.js 18, developers can write cleaner, more efficient code thanks to built-in fetch support, eliminating the need for external libraries.

node index.js

Read .env File Natively

Node.js 20 introduces native support for .env files, making it easier to manage environment variables. You no longer need to use the dotenv package.

node --env-file=.env.local index.js

Testing with node:test

The node:test library in Node.js 20 simplifies the setup and reduces dependencies needed for projects.

node --test

Task runner with node --run

The node --run command introduced in Node.js 22 provides a built-in mechanism for a task runner, complementing but not replacing existing package managers like npm, yarn, or pnpm.

Intentional limitations

node --run is not meant to match the behaviors of npm run or of the run commands of other package managers. The Node.js implementation is intentionally more limited, in order to focus on top performance for the most common use cases.

node --run start

Permission model

Node.js 22 enhances application security with an experimental permission model (--experimental-permission), offering controls similar to those seen in Deno.

node --experimental-permission index.js

Import ESM modules from CJS

The ability to import ESM modules from CommonJS scripts under the --experimental-require-module flag in Node.js 22 simplifies module management and encourages the adoption of ESM.

node --experimental-require-module index.cjs
