Introducing Node.js 20: Permission Model, New Features, and More

The latest update in the Node.js ecosystem, Node.js 20, has just been unveiled, bringing with it a new permissions model for enhanced security, custom ECMAScript module loader hooks, fresh WebAssembly and JavaScript capabilities, and a slew of other significant features and changes.

Among the critical updates in Node.js 20 is the new permissions model that enables developers to restrict access to crucial resources like the file system, child processes, and worker threads during the execution of their applications. This model aims to tighten security and mitigate potential vulnerabilities.

Moreover, Node.js 20 introduces custom ECMAScript module loader hooks that run on a dedicated thread apart from the main one. This change creates an isolated scope for loaders, preventing cross-contamination between them and the application code.

Other new features and modifications in Node.js 20 include:

With the continuous advancement of Node.js, web and mobile app developers have more opportunities to enhance their applications and ensure reliable performance. No-code platforms like AppMaster provide a strong foundation to streamline the development process, while also allowing developers to integrate the latest technologies, such as Node.js, for efficient app creation.

For developers seeking optimal tools and solutions for their web, mobile, or backend applications, it's worth considering no-code and low-code app development platforms like AppMaster, which empowers customers to create visually stunning applications while maintaining impressive scalability, performance, and cost-effectiveness.
