What is the method to integrate a property into an interface via declarations, while avoiding full object overwriting?
declare module 'fastify' {
interface FastifyRequest {
user: User;
}
}
//auth.ts
...
const user = jwt.verify(
req.headers.authorization ?? '', // Error: Property 'headers' does not exist on type 'FastifyRequest'
...
I Discovered a fix:
All you need to do is include an import statement with the module you are declaring, or use a triple slash reference like this:
/// <reference path="<path-to-typings-dir>" />
or
import fastify from "fastify";
declare module 'fastify' {
export interface FastifyRequest {
user: any;
}
}
