Original Post: 10 modern Node.js runtime features to start using in 2024
This article explores ten modern Node.js runtime features to utilize in 2024. Highlights include Bun, which is making strides with Node.js APIs, and Node.js runtime’s rich standard library and capabilities.
Key features discussed:
- Node.js Test Runner: Native test runner introduced, reducing the need for external test libraries like Jest.
- Node.js Native Mocking: Allows for native mocking of modules, introduced in Node.js 18.
- Node.js Native Test Coverage: Experimental feature for test coverage introduced in Node.js 20.
- Node.js Watch Mode: Native file-watch capability, allowing for automatic script execution on file changes.
- Node.js Corepack: Manages package managers to avoid conflicts across projects.
- Node.js .env Loader: Native support for loading environment variables from .env files.
- import.meta Support for dirname and file: Simplifies getting current file’s directory name and file path in ESM.
- Node.js Native Timers Promises: Allows using timers with promises, removing the need for manual promise wrapping.
- Node.js Permissions Model: Experimental feature for setting resource constraints (e.g., file system access).
- Node.js Policy Module: Implements module integrity checks to prevent malicious code from loading.
Staying updated with these features can lead to writing more efficient, performant, and secure code. Additionally, leveraging tools like Snyk can help maintain a secure development ecosystem by identifying vulnerabilities in dependencies.
