Introduction

Welcome to the GraphQL playground for managing, users, posts, comments, and much more. This project leverages Apollo GraphQL, Node Express, PostgreSQL, and JWT for user authentication, providing a robust and secure environment for managing data.

Before proceeding, you need to register or log in to access the GraphQL endpoint.

Accessing GraphQL Playground

• Open http://localhost:5000/playground in your browser after running the server locally.
• You'll be directed to the GraphQL authentication page to register or log in.

Registration

To register as a new user:

• Navigate to http://localhost:5000/graphql/auth/ within the GraphQL playground.

Use the following mutation:

mutation register {
    registerUser(
        email: String!
        username: String!
        password: String!
        role: String! # admin or user
    ): Users
}

• Provide your email, username, password, and role (admin or user).

Login

Once registered, log in using your credentials:

• Navigate to http://localhost:5000/graphql/auth/ within the GraphQL playground.

Use the following mutation:

mutation login {
    loginUser(email: String!, password: String!) {
        id
        username
        email
        role
        token # Use this token for authorization
    }
}

• Provide your username and password to receive a token for authentication.
