JWT integration in GraphQL

Introduction

JWT integration helps securely identify users when they access a database through GraphQL. It keeps data safe by checking who is allowed to see or change it.

When you want to make sure only logged-in users can see their own data.

When you need to check user roles before allowing certain database actions.

When building apps where users must stay logged in without typing passwords repeatedly.

When you want to pass user info safely between client and server in GraphQL requests.

Syntax

GraphQL

Authorization: Bearer <your_jwt_token>

The JWT token is sent in the HTTP header named 'Authorization'.

The word 'Bearer' is followed by a space and then the token string.

Examples

This example shows a typical JWT token sent in the header.

GraphQL

Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...

A GraphQL query that requests user data, which requires JWT for access.

GraphQL

query { user { id name } }

Sample Program

This GraphQL query asks for the current user's id, name, and email. The JWT token in the Authorization header proves who the user is.

GraphQL

query GetUserData {
  user {
    id
    name
    email
  }
}

# HTTP Header:
# Authorization: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VySWQiOiIxMjM0NSIsIm5hbWUiOiJKb2huIERvZSJ9.sflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c

Important Notes

Always keep your JWT secret safe to prevent unauthorized access.

JWT tokens usually expire; your app should handle token renewal smoothly.

Use HTTPS to protect JWT tokens during transmission.

Summary

JWT integration secures GraphQL database access by verifying user identity.

Tokens are sent in the Authorization header as 'Bearer <token>'.

This method helps control who can see or change data in your app.
