What is @esbuild/win32-x64?
The @esbuild/win32-x64 npm package is a binary package for the esbuild bundler and minifier tool. It is specifically compiled for Windows x64 systems. Esbuild is a fast JavaScript bundler and minifier that compiles TypeScript, JavaScript, and JSX files into a single output file. It is designed to be extremely fast and to provide a simpler and more efficient workflow for web development.
What are @esbuild/win32-x64's main functionalities?
Bundling JavaScript
This feature allows you to bundle multiple JavaScript files into a single output file, which can be used in a browser or other JavaScript environments.
require('esbuild').build({
entryPoints: ['app.js'],
bundle: true,
outfile: 'out.js'
}).catch(() => process.exit(1))
Minifying JavaScript
This feature enables the minification of JavaScript code to reduce file size, which is beneficial for faster loading times in production environments.
require('esbuild').build({
entryPoints: ['app.js'],
minify: true,
outfile: 'out.js'
}).catch(() => process.exit(1))
Transpiling TypeScript
This feature allows you to transpile TypeScript code into JavaScript, enabling you to use TypeScript's features while maintaining compatibility with JavaScript environments.
require('esbuild').build({
entryPoints: ['app.ts'],
bundle: true,
outfile: 'out.js'
}).catch(() => process.exit(1))
JSX Support
This feature provides support for JSX syntax, commonly used in React applications, allowing you to bundle and transpile JSX files directly.
require('esbuild').build({
entryPoints: ['app.jsx'],
bundle: true,
outfile: 'out.js'
}).catch(() => process.exit(1))
Other packages similar to @esbuild/win32-x64
webpack
Webpack is a powerful module bundler that can handle not only JavaScript but also assets like images, fonts, and stylesheets. It has a larger ecosystem of plugins and loaders, allowing for a highly customizable build process. Compared to esbuild, webpack is more established but generally slower due to its more complex features.
rollup
Rollup is another JavaScript module bundler that is well-suited for libraries and applications. It uses a different approach to bundling than webpack, focusing on the efficiency of the final bundle. Rollup is known for producing smaller bundles, but esbuild is typically faster in terms of build speed.
parcel
Parcel is a web application bundler that offers a zero-configuration experience. It is designed to be fast and easy to use, automatically handling transformations and dependencies. While Parcel is user-friendly and fast, esbuild often outperforms it in terms of raw build speed.
terser
Terser is a JavaScript parser, mangler, and compressor toolkit for ES6+. It is commonly used for minifying JavaScript files. Unlike esbuild, terser does not bundle files but focuses solely on minifying and optimizing JavaScript code.

The "preserve" JSX mode now preserves JSX text verbatim (#3605)
The JSX specification deliberately doesn't specify how JSX text is supposed to be interpreted and there is no canonical way to interpret JSX text. Two most popular interpretations are Babel and TypeScript. Yes they are different (esbuild deliberately follows TypeScript by the way).
Previously esbuild normalized text to the TypeScript interpretation when the "preserve" JSX mode is active. However, "preserve" should arguably reproduce the original JSX text verbatim so that whatever JSX transform runs after esbuild is free to interpret it however it wants. So with this release, esbuild will now pass JSX text through unmodified:
// Original code
let el =
<a href={'/'} title=''"'> some text
{foo}
more text </a>
// Old output (with --loader=jsx --jsx=preserve)
let el = <a href="/" title={`'"`}>
{" some text"}
{foo}
{"more text "}
</a>;
// New output (with --loader=jsx --jsx=preserve)
let el = <a href={"/"} title=''"'> some text
{foo}
more text </a>;

Allow JSX elements as JSX attribute values
JSX has an obscure feature where you can use JSX elements in attribute position without surrounding them with {...}
. It looks like this:
let el = <div data-ab=<><a/><b/></>/>;
I think I originally didn't implement it even though it's part of the JSX specification because it previously didn't work in TypeScript (and potentially also in Babel?). However, support for it was silently added in TypeScript 4.8 without me noticing and Babel has also since fixed their bugs regarding this feature. So I'm adding it to esbuild too now that I know it's widely supported.
Keep in mind that there is some ongoing discussion about removing this feature from JSX. I agree that the syntax seems out of place (it does away with the elegance of "JSX is basically just XML with {...}
escapes" for something arguably harder to read, which doesn't seem like a good trade-off), but it's in the specification and TypeScript and Babel both implement it so I'm going to have esbuild implement it too. However, I reserve the right to remove it from esbuild if it's ever removed from the specification in the future. So use it with caution.

Fix a bug with TypeScript type parsing (#3574)
This release fixes a bug with esbuild's TypeScript parser where a conditional type containing a union type that ends with an infer type that ends with a constraint could fail to parse. This was caused by the "don't parse a conditional type" flag not getting passed through the union type parser. Here's an example of valid TypeScript code that previously failed to parse correctly:
type InferUnion<T> = T extends { a: infer U extends number } | infer U extends number ? U : never
