In practice it turned out that it is better when there are no definitions for locals at all. If necessary, it is easier to determine without conflicts directly in the code

declare module 'fastify' {
  interface FastifyReply {
    locals: Partial<{ assetsManifest: AssetsManifest }> | undefined;
  }
}

server.addHook('preHandler', (request: FastifyRequest, reply: FastifyReply, done: HookHandlerDoneFunction) => {
  if (typeof reply.locals === 'undefined') {
    reply.locals = {};
  }
  reply.locals.assetsManifest = assetsManifest();
    done();
});

Indeed that's a good remark. Would you mind write a little Typescript usage in the Readme? Explaining the use of this plugin with Typescript like you did in the test?

Why this addition?

[TakNePoidet]

Moved to a separate interface for better readability

This option seems less clear:

declare module 'fastify' {
  interface FastifyReply {
    locals:
      | Partial<{
        appVersion: string;
        assetsManifest: AssetsManifest;
      }>
      | undefined;
    }
}

but AssetsManifest is not defined in the example it could lead to misreading don't you think?

[TakNePoidet]

Removed undeclared types and added another example with an object

interface Locals {
  appVersion: string,
  isAuthorized: boolean,
  user?: {
    id: number
    login: string
  }
}
