Loving snowpack for a new app we've been working on! I've added @snowpack/plugin-webpack in my build step and can't seem to change the prefix for assets inbuild/index.html. From the webpack docs, this seems to be specified in config.output.publicPath.

I've tried:

/** @type {import("snowpack").SnowpackUserConfig } */
const ASSET_PATH = process.env.ASSET_PATH || '/my/custom/prefix';

module.exports = {
  mount: {
    public: '/',
    src: '/_dist_',
  },
  plugins: [
    '@snowpack/plugin-react-refresh',
    '@snowpack/plugin-typescript',
    [
      '@snowpack/plugin-webpack',
      {
        extendConfig(config) {
          config.output.publicPath = ASSET_PATH;
          return config;
        },
      },
    ],
  ],
};

$ npm run build

<!DOCTYPE html>

  <script src="/js/index.437f7f777abdf2a7967d.js"></script>
</body>
</html>

I'd like to use a relative prefix "./", but the prefix does not show up in the final build/index.html imports.

for anybody ending up here through google search: A possible fix is to set buildOptions.baseUrl in the snowpack config https://www.snowpack.dev/reference/configuration#buildoptionsbaseurl
