What is this?

@brillout/vite-plugin-import-build automatically loads your server build (i.e. your files at dist/server/).

Vike and Telefunc automatically add this plugin to your Vite app: there is nothing for you to do and you can usually ignore this plugin.

Manual import

Most of the time @brillout/vite-plugin-import-build is able to automatically import your server build (i.e. your files at dist/server/) — there is nothing for you to do.

But @brillout/vite-plugin-import-build doesn't work if you use Yarn PnP and you'll keep getting following error. The workaround is to manually import your server build.

# Yarn PnP users always get this error:
[@brillout/vite-plugin-import-build][Wrong Usage] Cannot find server build. (Re-)build your app
and try again. If you still get this error, then you may need to manually import the server build.

[!WARNING] If you aren't using Yarn PnP and you keep getting this error, then it's a bug that should be fixed — please open a new issue.

To manually import your server build:

// server.js

// Load server build, see https://github.com/brillout/vite-plugin-import-build#manual-import
import './path/to/dist/server/importBuild.cjs'

// Your server code (Express.js, Vercel Serverless/Edge Function, Cloudflare Worker, ...)
// ...

Make sure to import dist/server/importBuild.cjs only in production. See Conditional manual import if your production and development share the same server entry file.

If you use vite.config.js > build.outDir then replace dist/server/importBuild.cjs with ${build.outDir}/server/importBuild.cjs.

What it does

[!NOTE] This section is meant for library authors. As a user, you don't need to read this. If you have a problem, read Manual import instead or reach out to maintainers.

@brillout/vite-plugin-import-build does two things:

• Generates an "import build" file at dist/server/importBuild.cjs.
• Generates an "auto importer" file at node_modules/@brillout/vite-plugin-import-build/dist/autoImporter.js.

The import build file (dist/server/importBuild.cjs) enables tools, such as Vike and Telefunc, to consolidate their server entry file into a single entry file at dist/server/importBuild.cjs. We recommend having a quick look at the content of dist/server/importBuild.cjs: you'll see that it essentially loads built user files that live inside dist/server/ (e.g. for Telefunc transpiled .telefunc.js user files, and for Vike transpiled +Page.js user files).

The auto importer file (node_modules/@brillout/vite-plugin-import-build/dist/autoImporter.js) automatically imports dist/server/importBuild.cjs, so that the user doesn't have to manually import dist/server/importBuild.cjs himself as shown in the following. That's the only purpose of the auto importer.

// server/index.js (the user's server entry file)

// Without the auto importer, the user would have to manually import dist/server/importBuild.cjs
// in his server entry file like this:
if (process.env.NODE_ENV === 'production') {
  await import('../dist/server/importBuild.cjs')
}
