What's an Middleware Plugin?
Middleware plugins have the capability to modify the API (web and cli) layer, either adding new endpoints or intercepting requests.
API
interface IPluginMiddleware<T> extends IPlugin<T> {
register_middlewares(app: any, auth: IBasicAuth<T>, storage: IStorageManager<T>): void;
}
register_middlewares
The method provide full access to the authentification and storage via auth
and storage
. app
is the express application that allows you to add new endpoints.
public register_middlewares(
app: Application,
auth: IBasicAuth<CustomConfig>,
storage: IStorageManager<CustomConfig>
): void {
const router = Router();
router.post(
'/custom-endpoint',
(req: Request, res: Response & { report_error?: Function }, next: NextFunction): void => {
const encryptedString = auth.aesEncrypt(Buffer.from(this.foo, 'utf8'));
res.setHeader('X-Verdaccio-Token-Plugin', encryptedString.toString());
next();
}
);
app.use('/-/npm/something-new', router);
}
The auth
and storage
are instances and can be extended, but we don't recommend this approach unless is well founded.
A good example of a middleware plugin is the verdaccio-audit.

The middleware are registrered after built-in endpoints, thus, it is not possible to override the implemented ones.
