deno: A Secure JavaScript and TypeScript Runtime
A brief introduction to the project:
deno is a secure JavaScript and TypeScript runtime built with Rust and V8 JavaScript engine. It was created by Ryan Dahl, the original creator of Node.js, with the aim of addressing the security concerns and design flaws of Node.js. deno provides a runtime environment that allows developers to execute JavaScript and TypeScript code securely, without the need for a package manager like npm.
Project Overview:
deno aims to provide a secure and reliable runtime for executing JavaScript and TypeScript code. It addresses the security concerns of Node.js by implementing several key features, such as isolated script execution, controlled permissions, and a built-in dependency inspector.
The project is relevant and significant because it offers a more secure alternative to Node.js, which has been widely adopted for server-side scripting and build tools. With deno, developers can run JavaScript and TypeScript code without the risk of executing malicious or untrusted code from dependencies.
The target audience of deno includes JavaScript and TypeScript developers who want a more secure runtime for their applications, as well as organizations or individuals seeking a safer alternative to Node.js for their server-side scripting needs.
Project Features:
- Secure Environment: deno provides a secure environment for executing JavaScript and TypeScript code by default. It ensures that scripts can only access necessary resources and permissions through a controlled permissions system.
- Built-in TypeScript Support: deno has built-in TypeScript support, allowing developers to write and execute TypeScript code seamlessly. It eliminates the need for separate transpilation and build processes.
- Module System: deno has a built-in module system that supports both local and remote modules. It provides a secure and reliable way to import and use external modules in JavaScript and TypeScript code.
- Standard Library: deno includes a standard library that provides various utilities and modules for common tasks. This eliminates the need for external dependencies and makes it easier to build and deploy applications.
Technology Stack:
deno is built with Rust, a systems programming language known for its safety, performance, and concurrency features. Rust ensures that deno is secure and reliable, with minimal risk of memory leaks or undefined behavior.
It uses the V8 JavaScript engine, which is also used in Google Chrome, to execute JavaScript and TypeScript code. V8 provides high-performance execution, efficient memory management, and support for modern JavaScript features.
Project Structure and Architecture:
deno follows a modular architecture, where different components are responsible for specific tasks. The core components include the runtime, the module system, the permissions system, and the dependency inspector.
The runtime component executes JavaScript and TypeScript code in a secure and isolated environment. It ensures that scripts only have access to necessary resources and permissions.
The module system handles the import and execution of external modules. It supports both local and remote modules, providing a way to import and use external code in deno applications.
The permissions system controls the access to resources and permissions by scripts. It allows developers to specify and control the permissions required by their scripts.
The dependency inspector is responsible for analyzing and inspecting the dependencies of scripts. It provides information about the dependencies used by a script, including their versions and possible security vulnerabilities.
Contribution Guidelines:
deno is an open-source project and encourages contributions from the community. The project has a dedicated GitHub repository where developers can contribute bug reports, feature requests, or code contributions.
The contribution guidelines are outlined in the project's README file, which provides information on how to contribute to deno. It includes guidelines for creating issues, submitting pull requests, and contributing to the codebase.
The project also has specific guidelines for coding standards and documentation. It encourages developers to follow the Rust and TypeScript coding styles, as well as providing thorough documentation for new features and changes.
