Property 'locals' not on 'Response' type

I am trying to use res.locals to pass data between middlewares in a Restify app, but TypeScript is blocking me.

Do I need a plugin or is there an alternative solution for passing data between middlewares?

Yes, you need a plugin to use res.locals in a Restify app with TypeScript. One alternative solution for passing data between middlewares is to use req.data instead of res.locals. You can define a custom interface for req to include the data property and use it in your middlewares.
