Svelte preprocessing utilities
Yarn
yarn add -D spreNPM
npm i -D spreUse onImportDeclaration to re-write imports in the script block.
- import { Ad as Ad2 } from "svelte-lib";
- import { Bridge } from "svelte-lib";
+ import Ad2 from "svelte-lib/lib/Ad.svelte";
+ import Bridge from "svelte-lib/lib/Bridge.svelte";// svelte.config.js
import spre from "spre";
export default {
preprocess: [
spre({
onImportDeclaration({ sourceName, importName, localName }) {
return `import ${localName} from "${sourceName}/lib/${importName}.svelte";`;
},
}),
],
};Example that only re-writes non-default and not namespaced imports from a specific library:
spre({
onImportDeclaration({ sourceName, importName, localName }) {
if (sourceName !== "svelte-lib") return;
if (isDefaultImport || !importName) return;
return `import ${localName} from "${sourceName}/lib/${importName}.svelte";`;
},
}),
