esbuild VS svgr

At first we wanted to just get rid of all the helper utilities. Keep only the kernel, but this would mean a loss of backward compatibility. We needed some efficient code processing instead with recomposition and tree-shaking. We needed a bundler. But which one? Our testing approach relies on targets, not sources. We rebuilt the project frequently, speed was critical requirement. In essence, we chose a solution from a couple of among all available alternatives: esbuild and parcel. Esbuild won. Specifically in our case, it proved to be more productive and customizable.

During my search for deploying Lambdas via GitHub actions, I came across a tutorial that utilized ncc for converting TypeScript and bundling. While ncc is effective, I discovered esbuild, which proved to be significantly faster and perfectly suited to my requirements.

The advent of esbuild, the native support for ES Modules in browsers, the widespread adoption of import map, the emergence of tools like Native Federation, and the Nx ecosystem all combine to forge a flexible and well-maintained Micro Frontend Architecture.

EsBuild is a relatively new, blazing-fast JavaScript bundler and minifier. It stands out for its high performance, significantly speeding up the build process in development pipelines.

Unlike Webpack, the Vite DevServer only compiles files when they are requested. It leverages ES module imports, which allow JS files to import other files without needing to bundle them together during development. When one file changes, only that file needs to be re-compiled, and the rest can remain unchanged. Project files are compiled with Rollup.js. Third-party dependencies in node_modules are pre-compiled using the ultra-fast esbuild bundler for maximum speed, and they are cached until the dependency version changes. Vite also provides a client script for hot module reloading.

Use esbuild to build the React code into a form executable on both the server and client sides.

The functions will bundle using esbuild. For that, it is required to install esbuild globally:

TSX is the newest and most improved version of our ts-node, using ESBuild to transpile TS files to JS very quickly. The most interesting part is that TSX was developed to be a complete replacement for Node, so you can actually use TSX as a TypeScript REPL, if you install it globally with npm i -g tsx, just run tsx in your terminal and you can write TSX natively. But what's even cooler is that you can load TSX for all TypeScript files using --loader tsx when you run your file. For example, let's say we have this file called index.ts:

esbuild plus Vite is out of developer preview and enabled by default, yielding 67%, 87%, 80% speed improvements for build time, hybrid build time and hybrid serve time respectively.

//@ts-check // eslint-disable-next-line @typescript-eslint/no-var-requires const { composePlugins, withNx } = require('@nx/next'); /** * @type {import('@nx/next/plugins/with-nx').WithNxOptions} **/ const nextConfig = { nx: { // Set this to true if you would like to use SVGR // See: https://github.com/gregberge/svgr svgr: false, }, }; const plugins = [ // Add more Next.js plugins to this list if needed. withNx, ]; module.exports = composePlugins(...plugins)(nextConfig);

Most of the time, developers tend to add svg images to an assets directory and import them either directly or as a React component. This process not only increases your app bundle size but also makes managing all the assets difficult. What if there was a way to manage all the application icons like the way we import them from any other icon library? Yes, react-svgr helps you manage all the icons in your React application.

If you are using react, there is a tool called SVGR, which will take in an SVG file and return a react component with all the props. This can be really useful if you want to treat SVG more like a markup that will be embedded directly into your HTML. This becomes really helpful when you want to style SVG through props or add transformations and animations. Using SVG directly in markup has so many perks and advantages to the point i don't use them as source in image tags.

Really interesting framework agnostic approach, but I think SVGR is a better option for my React homies. It imports an SVG file as a React component. Shouts also to react-icons if Font Awesome, Material Icons and friends are more your bag.

SVGR

There is another way to import an SVG in Create React App, though. We can import the SVG as a ReactComponent. This is because CRA leverages SVGR to process SVGs.

const { types } = require('@babel/core'); module.exports = { ... template: function svgrCustomTemplate( { imports, interfaces, componentName, props, jsx, exports }, { tpl } ) { // меняем корневой элемент на SvgIcon jsx.openingElement.name.name = 'SvgIcon'; jsx.closingElement.name.name = 'SvgIcon'; // https://github.com/gregberge/svgr/issues/530 // при изменении корневого элемента пропадает спред пропсов // поэтому необходимо добавить спред пропсов самостоятельно jsx.openingElement.attributes.push( types.jSXSpreadAttribute(types.identifier('props')) ); return tpl` ${imports}; import { SvgIcon } from '../SvgIcon'; ${interfaces}; const ${componentName} = (${props}) => ( ${jsx} ); ${exports}; ` } }

Is this an icon or icon set? Because you can absolutely change SVG icons into react components with SVGR. https://react-svgr.com/
