ts-loader VS responsive-loader

It'll be a little different than your typical "what is webpack?" article in that I write this as the maintainer of ts-loader, a loader used for integrating TypeScript with webpack. I've worked in the webpack ecosystem for some years now, and I'll share some of my experiences with you.

why I use @babel/preset-typescript over ts-loader and awesome-typescript-loader to complie TypeScript? it's blazingly faster than the others and has more perks(read #4) ts-loader doesn't natively support HMR(Hot Module Replacement) awesome-typescript-loader's latest release is on Jun 22, 2018 TypeScript With Babel: A Beautiful Marriage - Matt Turnbull's Post

Okay. The normal setup is that you use https://github.com/TypeStrong/ts-loader or https://github.com/TypeStrong/fork-ts-checker-webpack-plugin as part of your Webpack config. Those will run the TS compilation step as part of the Webpack processing sequence.

I've recently tried SWC for building my project instead of ts-loader and was blown away by its performance (I got 8x-10x speedup on a Windows machine).

{ "compilerOptions": { "target": "esnext", "module": "esnext", "strict": true, "jsx": "preserve", "importHelpers": true, "moduleResolution": "node", "experimentalDecorators": true, "skipLibCheck": true, "esModuleInterop": true, "allowSyntheticDefaultImports": true, "sourceMap": true, "baseUrl": "./", "outDir": "./dist", // https://github.com/TypeStrong/ts-loader/issues/1138 "importsNotUsedAsValues": "preserve", "types": [ "webpack-env" ], "paths": { "@/*": [ "src/*" ], "@shared/*": [ "../shared/*" ] }, "lib": [ "esnext", "dom", "dom.iterable", "scripthost" ] }, "include": [ "src/**/*.ts", "src/**/*.tsx", "src/**/*.vue", "tests/**/*.ts", "tests/**/*.tsx", "../shared/**/*" ], "exclude": [ "node_modules" ] }

See https://github.com/TypeStrong/ts-loader#happypackmode. Switching to esbuild-loader cut my build time in half.

the ATypeThatDescribesYourImageLoader type could be an interface that describes what your image loader returns. For example I use https://github.com/dazuaz/responsive-loader so I have types like so

You can access any images or videos you drop in the studio via mediaFiles variable which is an object where file names are the keys. Implicitly there is a Webpack Responsive Loader involved which gives you src and placeholder.
