leaysgur / replace-vite-asset-path.mjs
Created May 3, 2022 04:04
Work around for https://github.com/withastro/astro/issues/2146
// @ts-check
import fs from "node:fs/promises";
import path from "node:path";
// This script is temporary work-around for issue,
// https://github.com/withastro/astro/issues/2146
// TL;DR, we need to replace all url() in CSS manually...
// e.g. url(__VITE_ASSET__********__) => url(/assets/asset.********.webp)
// Some url() work fine if they are updated to data-url.
