TypeScript VS esbuild

TypeScript公式サイト

There's also a slight performance caveat when it comes to interfaces vs intersections (&) to keep in mind: https://github.com/microsoft/Typescript/wiki/Performance#pre...

Tip: You can find official docs and guides at typescriptlang. org.

Node.js and TypeScript installed locally

Language: TypeScript (for type safety and better developer tooling)

It's extremely popular in React, Node.js, and full-stack TypeScript applications because it provides:

https://github.com/microsoft/TypeScript/blob/main/LICENSE.tx...

The license is Apache 2.0. With the trademark, they can tell everyone not to call their thing TypeScript but at this point, given the license, they cant't tell them not to copy it and change it and distribute that new thing (assuming the new distributors do so under the correct conditions).

But that is not the case, so you’d need a single cast to make it work (from number to ClampedNumber<1,200>) or however exactly you’d want to express this.

Tbf having looked more closely into how typescript handles number range types, I don’t think I would ever use them. Not very expressive or clear. I think I hallucinated something closer to what is in this proposal: https://github.com/microsoft/TypeScript/issues/43505

I still think that the general idea of communicating what acceptable input is via the type system is a good one. But the specifics of doing that with numbers isn’t great in typescript yet.

esbuild is still a Go app today: https://github.com/evanw/esbuild

The first hints of what become Bun were when Jared experimented at porting that to Zig.

In the following sections, we will explore how does it do what it does using one such tool called esbuild

esbuild Description: a Javascript/TypeScript/React compiler written in Go. What we like: It's the OG compiler/bundler for JS/TS. It was orders of magnitude faster than anything else before it was cool. What we don't like: It's lost some ground to tools such as bun.

Tree shaking works as expected for downstream packages using esbuild in the second case, which someone else in the linked issue pointed out: https://github.com/evanw/esbuild/issues/1420#issuecomment-96...

I used Zod and bundled with esbuild, and it works great!

TypeScript requires a compilation step before execution. Although Node "is starting" to offer native support for .ts, I opted here for ESBuild (an ultra-efficient bundler), to generate a JavaScript file executable simply with Node: esbuild src/index.ts --bundle --format=esm --outfile=dist/index.js --platform=node --target=node22.14 && node dist/index.js

If the developer needs to enable rich on-page interactivity or embed a mini React app — esbuild is embedded and integrated.

Use webpack or esbuild for bundling and pruning dead code Want to audit your bundle? Tools like pkg-size or cost-of-modules can show you which packages are inflating your deploy size.
