Difference between NPM and BUN
Bun is a new JavaScript runtime built from scratch to serve the modern JavaScript ecosystem. It has three major design goals:
Speed. Bun starts fast and runs fast. It extends JavaScriptCore, the performance-minded JS engine built for Safari. As computing moves to the edge, this is critical.
Elegant APIs. Bun provides a minimal set of highly-optimimized APIs for performing common tasks, like starting an HTTP server and writing files.
Cohesive DX. Bun is a complete toolkit for building JavaScript apps, including a package manager, test runner, and bundler.
Speed difference while installing packages
In this test i copied remix template
bun create remix
bun installation package test
The installation of packages is done 10.36 seconds
npm test
It takes 2 minute to install all packages
Lets take another test.
vite app
I created vite app with npm
npm create vite@latest
bun package installer
bun takes 2.53 second
Npm package installer test
npm takes 19 second
lets take test of react app installation. The command bun create react app1
give error. so i used this command
npm create-react-app my-app
with bun
bun takes 6.29 seconds
npm installed in 10 seconds
Speed test between both
this is the code for print numbers
console.time('test');
for (let i = 0; i < 10000; i++) console.log(i)
console.timeEnd("test");
bun test
node test
bun is much faster
Node
Advantages:
Extremely popular → many community projects, resources, job offers, etc.
Overall, it is pretty nice and easy to use
Disadvantages:
Runs only JavaScript – TypeScript projects require additional tooling such as ts-node or swc-node
Vendored-by-default
node_modules
take up a lot of space and don’t scale with the numbers of projectsAPI not compatible with browser API.
Bun
Bun has three main goals:
Execute JavaScript as fast as possible
Provide great, complete, and fast tooling (bundler, package manager, etc.)
Be a drop-in replacement for all existing Node projects.
bun install (no bun.lockb) → 21 s
bun install (with bun.lockb) → 6.77 s
Summary
In conclusion, Node.js is currently the most popular choice for running JavaScript on the server, and it has a huge community and many resources available.
Bun, while still in early development, aims to provide the fastest possible JavaScript execution and a complete set of tools, making it a compelling option for those seeking performance.
