I believe you can use cookies

+1 for cookies

the traditional way of how cookies work ? server -->client <-->server ,

Yes you can use cookies from "next/headers" and get the cookie you want, in my case I am trying to extract the token and decode then get the user id But the problem I am facing now is how to access these data from a client component I am thinking about creating a provider in the top layout and pass the id in it But I don't know how :lol

here is some simple code to build that provider and get the id. setting up of the provider: session-provider.tsx

import React from "react";
import { createContext, useContext, useState } from "react";

// Define the type for the context value
export type SessionContextValue = {
  userId: string | null;
};

// Create a context to hold the state
const SessionContext = createContext<SessionContextValue | undefined>(
  undefined
);

// Custom hook to access the context
export const useSessionContext = (): SessionContextValue => {
  const context = useContext(SessionContext);
  if (!context) {
    throw new Error("useMapContext must be used within a MapProvider");
  }
  return context;
};

export interface SessionProviderProps {
  children: React.ReactNode;
  userId: string | null;
}

export const SessionProvider = ({ children, userId }: SessionProviderProps) => {
  return (
    <SessionContext.Provider value={{ userId }}>
      {children}
    </SessionContext.Provider>
  );
};

import React from "react";
import { createContext, useContext, useState } from "react";

// Define the type for the context value
export type SessionContextValue = {
  userId: string | null;
};

// Create a context to hold the state
const SessionContext = createContext<SessionContextValue | undefined>(
  undefined
);

// Custom hook to access the context
export const useSessionContext = (): SessionContextValue => {
  const context = useContext(SessionContext);
  if (!context) {
    throw new Error("useMapContext must be used within a MapProvider");
  }
  return context;
};

export interface SessionProviderProps {
  children: React.ReactNode;
  userId: string | null;
}

export const SessionProvider = ({ children, userId }: SessionProviderProps) => {
  return (
    <SessionContext.Provider value={{ userId }}>
      {children}
    </SessionContext.Provider>
  );
};

example usage: providers.tsx

import React from "react";
import { cookies } from "next/headers";
import { SessionProvider } from "@/components/providers";

export const Providers = ({ children }: { children: React.ReactNode }) => {
  const user_info = cookies().get("user");
  const user = decodeUser(user_info);

  return <SessionProvider userId={userId.id}>{children}</SessionProvider>;
};

import React from "react";
import { cookies } from "next/headers";
import { SessionProvider } from "@/components/providers";

export const Providers = ({ children }: { children: React.ReactNode }) => {
  const user_info = cookies().get("user");
  const user = decodeUser(user_info);

  return <SessionProvider userId={userId.id}>{children}</SessionProvider>;
};
