assertDir in lib mode not work

[lefreet]

Description

1. in doc. , it say that lib mode the assertDir and assetsInlineLimit do not take effect. with: https://cn.vitejs.dev/config/build-options.html#build-assetsdir

2. and then i found the code changed in : c976d10

3. we have some flow call apps，such as @foo/bar， it build to public/apps/@foo/bar by vite.build foreach app，and copy to @foo/bar/dist when publish，and copy back to /public when postinstall，called by systemjs as amd lib，so we can shared apps in hundreds of project.

4. but, the assertDir is not work when we build them to apps/...，it build in the lib as base64，as a large lib.

Suggested solution

• now, i hack the rollupOptions and vite:asset plugin to build the assets and chunks right with a env.appname in every build iteration. it not a elegant method but it work.

// configResolved
        rollupOptions: {
          output: {
            chunkFileNames: env.abc_app_name ? `apps/${CTX.env.abc_app_name}/chunks/[name].js` : 'views/__chunks__/[name].js',
            assetFileNames: env.abc_app_name ? `apps/${CTX.env.abc_app_name}/assets/[name]-[hash].[ext]` : 'views/__assets__/[name]-[hash].[ext]'
          }


// options
      const assetPlugin = options.plugins.find(p => p.name === 'vite:asset')
      const assetPluginLoad = assetPlugin.load
      assetPlugin.load = async (...args) => {
        const _lib = CTX.ResolvedConfig.build.lib
        CTX.ResolvedConfig.build.lib = false
        const id = await assetPluginLoad.call(assetPlugin, ...args)
        CTX.ResolvedConfig.build.lib = _lib
        return id
      }

so

1. why lib mode assertDir not work ？ some design considerations？
2. should the user config assetsInlineLimit，also can make the lib assert inline，so we can controll by ourself.
