This is an example of using GraphQL to handle user login/logout and registration

Well, GraphQL doesn't do this on its own it just passes the username and password to the request then the request is processed by passportjs which actually take care of everything.

Packages used for auth

• passport.js
• passport-local-mongoose

Installation

• clone the repo

git clone https://github.com/shalkam/graphql-login.git

then cd to the directory

cd graphql-login

Development

• First make sure that you MongoDB up and running (you can configure the database connection at /src/config.js)
• then just run

npm run dev

• Then you can browse to graphiql at : http://localhost:3000/graphqiql
• registration mutation:

mutation register {
  register(username:"test", password:"test") {
    username
    password
    message
  }
}

• login mutation:

mutation login {
  login(username: "test", password: "test") {
    username
    message
  }
}

• logout mutation:

mutation logout {
  logout {
    result
  }
}

Build

• run this command

npm run build

• This repo is based on this awesome boilerplate you will have all node packages bundled in just one file you will need to install only mongoose externally.
