Will Deno kill Node.js in 2021?
Deno vs Node.js - Quick Comparison
It all started with Ryan Dalh realizing that there are some certain shortcomings to his Node.js, such as:
- Security issues: all system calls are accessible, and this raised a few problems for security
- Meta-Build System GYP: made redundant by Chrome but still in use for Node.js
- package.json: causing developers to reply on NPM and modules directory concepts
- node_modules: gigantic dinosaur eating the module resolution algorithm alive
The most common usage for Deno and Node is building backend services, for example, REST API's. Let's look at HTTP performance.
Maximum latency test. Smaller is better—log scale.
Bigger is better. Percentage compared to Hyper (Rust server)
Deno Pros and cons
From all the information above, we can draw some conclusions about Deno & Node.js advantages and disadvantages
Deno is faster (check the abovementioned benchmark)
Deno is more secure: access is limited to the outside environment (standard)
Deno is compact, fixes node_modules' heaviness
Deno is decentralized, no more package manager
Deno is built on Typescript and so we have it available as default
Deno is more up-to-date with fewer issues
Deno community is expanding but the current volume is about 2% Node.js
Less code available on StackOverflow
Lack of package manager (npm)
Fewer libraries and modules in comparison with npm
Fast to develop, with some inevitable bugs
We have had our fun weighing the pros and cons of both Node.js & Deno’s. So it’s high time a conclusion is drawn.
At this point, Deno is mainly a cool & good enough playground for small personal Typescript projects. According to Dahl, Deno will “never really affect” the success of Node.js.
But in the future, when Deno is upgraded to version 1.0, it should be a strong option for more complex projects.
