 # สร้างไฟล์ src/shared/utils/jwt.util.ts 
 ```javascript 
 export function decodeJwt<T = unknown>(token: string): T { 
   const parts = token.split("."); 

   if (parts.length !== 3) { 
     throw new Error("Invalid JWT format"); 
   } 

   const payload = parts[1]; 

   const decoded = Buffer.from( 
     payload.replace(/-/g, "+").replace(/_/g, "/"), 
     "base64", 
   ).toString("utf-8"); 

   return JSON.parse(decoded) as T; 
 }

 ```javascript

 # วิธีใช้ pass value ตั้งแต่ controller เข้าไป 
 ```javascript 
 @ExtractAuthContext() authContext: AuthContext 
 ```
