Have you ever heard of Deno? This runtime is expected to be a future replacement for Node.js, which deserves closer attention. This article offers you to focus on Deno: definition, common points and differences with Node.js and future use.
What Is Deno?
The Main Features Of Deno
- Rust (Deno center was written in Rust while Node.js is in C++ );
Commonalities With Node.js
Since Deno was developed in the continuity of Node.js and had the role of coming to overcome the weak points of the latter. Both, therefore, converge on the same objective, and even if their respective operations are based on different mechanisms, they share many similarities:
- the command-line interface built from Rust which stands out for its responsiveness and integrates an API;
- operation with the Chrome V8 engine;
The Differences Between Deno And Node.js
The mechanics of importing modules are also different between the two. While ES modules are the default system Deno is built on, Node.js’ is CommonJS. Node’s official package manager is npm, while Deno allows importing any module from a simple URL. The latter enjoys excellent flexibility since it is possible to create packages without publishing them. Deno also provides additional tools that allow you to take over tasks usually performed by third-party tools such as WebPack. Among the tools integrated into Deno, we can mention others: grouping, testing, installation of scripts, formatting and debugging.
Deno, Favorite Candidate To Replace Node.js?
To conclude, the use of Deno has advantages, the main ones being security and performance. Rust has already made it possible to significantly improve many tools after their rewrite. However, the module compatibility issue remains unguaranteed: quite a few modules are guaranteed to work on both Node.js and Deno.
Another point: Deno has already been criticized for dependency management, which relies on a URL system rather than a package manager. This is a case to follow, but these few shadows on the board in no way diminish Deno’s indisputable advantages and effectiveness. This runtime undoubtedly has a bright future since it is only in the early stages of its development. We will have more answers with a few additional years of hindsight.
