Deno 1.31 Introduces Support for package.json Dependencies
Written on
The Rise of Deno
Deno is making significant strides to attract users from the Node.js community. A critical component of numerous web projects in recent years has been the package.json file, which contains essential information about dependencies and their respective versions, as well as commands that can be executed using npm. Deno 1.31 brings enhancements specifically designed to assist Node.js users.
Deno’s Latest Features
According to Bartek Iwa?czuk and his team, the freshly released Deno 1.31 version has introduced support for the package.json file. This means Deno can now install dependencies directly based on the information contained within the file. The announcement included a working example of such a file:
At present, only a limited selection of scripts is supported. More complex scripts, such as rimraf, may not function yet, but the development team aims to expand the functionality to match Node.js capabilities.
Understanding Deno’s Advantages
For many developers, it might still feel premature to fully adopt Deno, but now is an opportune time to stay informed about this emerging competitor to Node.js. Here are several improvements Deno offers over Node.js:
- Direct URL Dependencies: Instead of relying on a package.json file, dependencies are specified through URLs, which can be sourced from deno.land or various popular JS libraries.
- Built-in TypeScript: TypeScript support is included out of the box, eliminating the need to add additional dependencies for its use.
- Top-Level Await: Deno allows the use of await at the top level, simplifying asynchronous programming.
- Browser API Compatibility: Deno closely mirrors browser APIs, making it easier to transfer knowledge from frontend to backend development.
- Resource-Efficient Imports: Instead of using require, packages can be imported with the import statement, which conserves resources.
Deno's design offers meaningful improvements compared to Node.js, and while Node.js has introduced some similar features, such as top-level await and HTTP imports, Deno’s alignment with browser APIs remains a significant advantage.
