fix(auth): load auth.ts through Vite in builds and void prepare by Brooooooklyn · Pull Request #611 · voidzero-dev/void

Brooooooklyn · 2026-10-27T07:19:55Z

Problem

Dev loads auth.ts through a Vite module runner. vite build and void prepare (also void gen / void db) still used Node's own import(). So an auth.ts with a normal import failed there, while dev worked:

import { origins } from './lib/origins'   // no extension
import { fields } from '@schema/fields'   // Vite alias

Error: Cannot find module '.../lib/origins' imported from .../auth.ts

The loader also took export const auth / export const config. The Worker only imports the default export, so the schema could be built from a config the runtime never reads.

Fix

          before                    after
dev     : dev env runner       ->  dev env runner (no change)
build   : import()  ✗          ->  runnerImport + build's resolve.alias / tsconfigPaths
prepare : import()  ✗          ->  runnerImport + alias / tsconfigPaths from the app's resolved vite config (plugins included)
named export only : accepted   ->  "<path> has no default export. Export the auth config with `export default defineAuth(...)`."

viteAuthConfigImporter(root, mode, resolve) runs auth.ts once with Vite's runnerImport.
projectAuthConfigImporter(root) is for commands outside Vite. It resolves the app's vite config with its plugins (resolveConfig, serve, development), only when an auth.ts exists. Aliases that plugins add in config(), such as Void's @schema, are included.
devAuthConfigImporter(server) always gives an importer: the auth config environment, or else a runner with the dev server's resolved aliases.
loadVoidAuthConfig now needs an importer and accepts only a default export.

Tests

void prepare in a plain node child process (Vitest's runner would hide the bug): auth.ts imports an extensionless file, an alias from vite.config, and @schema added by a plugin's config() hook. All three fields reach the generated schema.
Build: routingPlugin buildStart with a resolved build config that has an alias. Same check.
Dev server without the auth config environment: the importer resolves an alias from the server's config.
A named-only export gives the clear error.
Each guarded change, reverted on its own, makes one of these tests fail.

Choices to check

Only resolve.alias and resolve.tsconfigPaths are passed on to the runner, not plugins. A plugin that resolves imports in resolveId without an alias is not applied to auth.ts outside dev.
Apps with auth.ts now resolve their vite config (with plugin config() / configResolved() hooks) during void prepare. That adds about 1s, and an error in the vite config or a plugin hook now stops prepare.
Named-only auth exports are now an error. They never worked at runtime.

Dev already loads auth.ts through a Vite module runner, but `vite build`, `void prepare` and the CLI commands that run it still used a plain Node `import()`. An auth.ts that imports a project file without an extension (`import './db'`) or through a Vite alias (`@schema/...`) failed there with "Cannot find module", even though dev worked. Builds and CLI commands now evaluate auth.ts once with Vite's `runnerImport`, so imports resolve as in dev. A build passes its own resolved aliases and `tsconfigPaths`; `void prepare` reads them from the app's Vite config. The loader also accepted `export const auth` or `export const config`, but the Worker only imports the default export, so the generated schema and the runtime could disagree. It now requires a default export and says to use `export default defineAuth(...)`. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

@Schema

`void prepare`, `void gen` and `void db generate` read only the raw vite.config to find aliases for auth.ts. Aliases that plugins add in their `config()` hook were missing, such as Void's own `@schema`, so an auth.ts with `import { ... } from '@Schema'` failed with "Cannot find module '@Schema'" there, while dev and build worked. These commands now resolve the app's Vite config with its plugins and use its aliases. When the dev server has no auth config environment, the migration fallback uses the server's resolved aliases too. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

`void prepare`, `void gen` and `void db generate` loaded the app's vite.config to find aliases for auth.ts. Evaluating it constructs the app's plugins, and Void's plugin writes generated files and Cloudflare config when constructed, so preparing types could change the project. `void prepare` must not boot the app's Vite. These commands now evaluate auth.ts without the app's Vite config. Imports still resolve without extensions, through tsconfig `paths`, and through Void's own `@schema` alias. An alias set only in vite.config resolves in dev and builds. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Fixed in 106d132 on #611, which this PR is stacked on. void prepare, void gen and void db generate no longer load the app's vite.config: auth.ts is evaluated with Vite's runnerImport (no config file), using tsconfig paths and Void's own @schema alias. The prepare test now has a vite.config that writes a marker file and checks it is never written.
