Error Handling

next-fetcher do not throwing any error during data fetching. But if you want to throw error you can use throwOnError() chaining method.

-Example-

fetcher.get("/api").throwOnError();
fetcher.post("/api").throwOnError();
fetcher.put("/api").throwOnError();
fetcher.delete("/api").throwOnError();

Typescript Usage

next-fetcher is typescript friendly. You can declare your response type like-

fetcher.get<data:any>("/api").throwOnError();
fetcher.post<{message:string}>("/api").throwOnError();
fetcher.put<{message:string}>("/api").throwOnError();
fetcher.delete<{message:string}>("/api").throwOnError();

Cookie Management(Session)

next-fetcher support cookie management system. You can add cookie or delete cookie using next-fetcher utility function.

import { addSession, deleteSession } from "next-fetcher";

//Add session (Adding cookie)
addSession('key', 'value', options);

//Delete Session (Removing cookie)
deleteSession('key', options);

NOTE! When deleting a cookie and you're not relying on the default attributes, you must pass the exact same path and domain attributes that were used to set the cookie:

deleteSession('key', { path: '/path', domain: '.yourdomain.com' });
