Node JS has been the default option for the JavaScript runtime environment, until the introduction of updated versions. The introduction of Deno and Bun has increased the runtime options for JavaScript developers. Make the right selection of JavaScript development from Deno vs Bun options and base the decision on relevant differences.
Both
Deno and Bun have similar runtime environments with few deviations. Take the
right call on the selection of a JavaScript runtime platform designed to fit
the development needs. It is easy to switch between the runtime environments
with the advice of expert developers. A quick run-over will ensure analysis of
the differentiators for the selection of the development platform. Even the
Node Js vs Deno vs Bun will provide the right direction to ensure selection of
the runtime environment.
Deno: The Detailed Information
It is the type of TypeScript & JavaScript developed by Ryan Dahl to overcome the shortcomings of Node JS. Deno has a security model that suits modern-day development needs and has multiple built-in tools. The key feature includes a built-in linter, bundling of scripts, TypeScript supports, and test runner.
Since
its inception, Deno has made significant progress in the developer community
due to multiple reasons. It comes with a V8 JavaScript engine to support the
JavaScript runtime environment needs.
Deno
is one of the self-contained binaries that can be installed in different ways
as per suitable OS. The simple way to download and execute the script is as
follows:
#
Linux and macOS
$
curl –fsSL https://deno.land/x/install/install.sh | sh
#
Windows PowerShell
$
iwr https://deno.land/x/install/install.ps1 -useb | iex
The advantages of Deno include –
●
Security is the top priority
●
It is supporting npm & Node modules
●
It ensures top-level support for TypeScript
●
For superior DX, Deno is adapting to higher web platform standards
Let
us look at some of the disadvantages associated with Deno –
●
It is less popular than Node JS among developers
●
Some of the APIs in Deno are unstable and not ready for use
●
Migrating from Node to Deno is hard
Set
up the Deno development environment after running the script and add the
official version of the Deno extension to VS Code. Deno is executing the code
by default in the sandbox and for easy access, the developer will be asked for
the relevant permissions. It is able to transpile TypeScript easily and increases
the overall efficiency of development with deno development company.
Bun: The Detailed Information
It
is the latest version of the JavaScript runtime environment. Bun was developed
to be the drop-in replacement for the TypeScript and JavaScript apps that
focuses mainly on performance levels. The platform is also regarded as an
all-in-one solution with features like transpiler, bundler, and package management
in one tool.
The main aims of Bun are as follows –
●
It ensures faster execution of the JavaScript programs
●
It provider faster tooling options
●
It is the drop-in replacement for the current Node projects
Deno
is using the same type of JavaScript execution engine as the Node, known as V8.
The top priority behind the creation of the platform is to take JavaScript
performance to the next level. Bun is programmed in Zig which is considered a
low-level language with minimal memory management features. It is the reason
for utilizing the extreme performance code and thus allowing the programs to be
segfault.
Bun
is primarily preferred as the npm-compatible package manager and gets tested on
the larger repository that needs more than 3,000 packages. The use of the
aforementioned tools ensures the speed-up of the development procedure and uses
Bun’s transpiler to be used as a runtime. Deno is the suitable alternative to
improved security structure for TypeScript and Bun is still in early
development, with the aim to ensure faster JavaScript execution.
Deno Vs Bun – What Set the Platforms Apart?
There
are different ways to evaluate the difference between the runtime environments
but check the relevant points to ensure optimal use of results. Let us look at
the prime difference between Deno and Bun –
Performance Comparison
Speed
is the prime factor that sets apart Bun from Deno. Bun is at least 2.5x better
speed between the two. It is because of the JavaScript Bun as the engine. Also,
Bun is written as Zig which provides developers control over memory.
Web APIs
Bun
has a series of Web APIs like WebSocket, Fetch, or ReadableStream that are
different from the Deno. The use of APIs is making the entire development
process simple and trustworthy.
Deno
is having the APIs not available in Node JS. Deno is using the fetch API to
send the HTTP requests and there is a list of vital APIs used by Deno to comply
with the requirements.
Transpiler
Bun
is able to transpile the TypeScript files easily. The difference from Deno is
that it supports TSX and JSX too.
Package Manager
Bun
has a centralized package manager that is functioning faster than the NPM. It
is using the compatible NodeJS module algorithm that can be used with safe NPM
packaging.
Built-In Test Runner
Deno is having the native test runner able to run integration tests way quicker than other dependencies across Node JS. Bun is also ensuring the test run as per relevant use and thus uses the latest version of JavaScript runtime for the best results.
The Final Talk!
The
primary goal of Deno is not to replace Node JS but to provide an efficient
alternative. It is similar to the comparison of Deno vs Bun and the developer
should make the final selection based on the present requirements.
Selection of the Bun will always be a challenge as it is the newer version and thus the chances of bugs or compatibility issues remain. But, Bun looks promising due to its development with Zig and looks like the technology to keep an eye on.
If you desire to get a faster runtime environment select Bun which has a complete set of tools for compilation. But, if you want to stick to the V8 engine and are looking for something better than Node JS then Deno is the best call.
