Django GraphQL JWT

JSON Web Token authentication for Django GraphQL.
Fantastic documentation is available at https://django-graphql-jwt.domake.io.

TestCoverageCodacyPackage version

Installation

Install last stable version from Pypi:

pip install django-graphql-jwt

Add middleware to your MIDDLEWARE settings:

MIDDLEWARE= [ # ..."django.contrib.auth.middleware.AuthenticationMiddleware", # ... ]

Add middleware to your GRAPHENE settings:

GRAPHENE= { "SCHEMA": "mysite.myschema.schema", "MIDDLEWARE": [ "graphql_jwt.middleware.JSONWebTokenMiddleware", ], }

Add backend to your AUTHENTICATION_BACKENDS:

AUTHENTICATION_BACKENDS= [ "graphql_jwt.backends.JSONWebTokenBackend", "django.contrib.auth.backends.ModelBackend", ]

Schema

Add django-graphql-jwt mutations to the root schema:

importgrapheneimportgraphql_jwtclassMutation(graphene.ObjectType): token_auth=graphql_jwt.ObtainJSONWebToken.Field() verify_token=graphql_jwt.Verify.Field() refresh_token=graphql_jwt.Refresh.Field() schema=graphene.Schema(mutation=Mutation)

This tutorial assumes you’re familiar with GraphQL & Python using Django and Graphene. If not, you could refer the previous article on Getting Started with Python and GraphQL

In this tutorial we will discuss about Authentication. Django have a built in concept of Users, so we need to send data to the server through a mutation to create User.

We will create a new folder and new file

When sending data to the server using mutation, we will send , and . The server will return the created object with all the information, where the client can ask the fields it wants.

Before executing it, we need to put the new mutation in the root file.

Execute the following code using Insomnia and we can see the new user created.

Querying the users

To list all the users we would create a query to send to the server.

We will add the following to the file.

We will also update root query class to enable users query.

We will send a query to the server to list all the users.

User Authentication

Authentication is enabled by default in Django using sessions. We will use library to implement JWT token in GraphQL.

A piece of data that identifies the User is send to a User when they sign up or log in. The same token should be sent by the User in HTTP Authorization header with the request when authentication is required.

We will configure by adding a new middleware in file. In the same file we will add the authentication backend settings.

What is Moesif? Moesif is the most advanced REST and GraphQL analytics platform used by Thousands of platformsto measure how your queries are performing and understand what your most loyal customers are doing with your APIs.

Next, we will import the library and update the class to have the following variables in file.

The library create three mutation:

We will use to authenticate the User with its username and password and obtain the JSON Web Token.

token_auth.png

We will use to verify that the token passed as an argument is a valid token.

verify_token.png

will generate a new token for non-expired tokens within the renewed expiration time.

Testing the authentication

To test if our authentication is working, we will create a query called that would return User’s information if logged in or will throw an error otherwise.

First, we will add query within the Query class in file.

For testing, we need to get a token using mutation and use it in our Query with HTTP Authorization header by adding prefix .

token_auth.png

We will add the HTTP Authorization header with the token content, prefix by word .

Finally, we will make the query which should identify our User.

test_authentication.png

We are able to create users and sign in with them. We will get error message if we will make a query without the HTTP header.

Okay, just let me play with it! To see the GraphQL in action, you can git clone and run this example app from GitHub.

In next tutorial - we will discuss about monitoring GraphQL APIs. Meanwhile, if you’ve any question, reach out to Moesif Team.

Authentication and Express Middleware

It's simple to use any Express middleware in conjunction with . In particular, this is a great pattern for handling authentication.

To use middleware with a GraphQL resolver, just use the middleware like you would with a normal Express app. The object is then available as the second argument in any resolver.

For example, let's say we wanted our server to log the IP address of every request, and we also want to write an API that returns the IP address of the caller. We can do the former with middleware, and the latter by accessing the object in a resolver. Here's server code that implements this:

var express =require('express');

var{ graphqlHTTP }=require('express-graphql');

var{ buildSchema }=require('graphql');

var schema =buildSchema(`

type Query {

ip: String

}

`);

const loggingMiddleware =(req, res, next)=>{

console.log('ip:', req.ip);

next();

}

var root ={

ip:function(args, request){

return request.ip;

}

};

var app =express();

app.use(loggingMiddleware);

app.use('/graphql',graphqlHTTP({

schema: schema,

rootValue: root,

graphiql:true,

}));

app.listen(4000);

console.log('Running a GraphQL API server at localhost:4000/graphql');

In a REST API, authentication is often handled with a header, that contains an auth token which proves what user is making this request. Express middleware processes these headers and puts authentication data on the Express object. Some middleware modules that handle authentication like this are Passport, express-jwt, and express-session. Each of these modules works with .

If you aren't familiar with any of these authentication mechanisms, we recommend using because it's simple without sacrificing any future flexibility.

If you've read through the docs linearly to get to this point, congratulations! You now know everything you need to build a practical GraphQL API server.

How to Auth: Secure a GraphQL API with Confidence

Graphql server authentication with JWT

Welcome, we will continue working on our Graphql to-do API, by setting up authorization for our app using JWT.

Getting Started

This tutorial will be focusing on:

  • What is JWT and how to use it
  • Hashing the password with bcryptjs
  • How to control who can interact with the data

Step 1: Install dependencies

You'll need to install and by running the following in the terminal:

or using npm

So, what are JSON Web Tokens and bcryptjs, and Why?

  1. JWT

JSON Web Token (JWT) is a compact, URL-safe means of representing claims to be transferred between two parties. more info. passing jwt tokens will take this formAlt Text

  1. bcryptjs

Is a way to hash the user info before hitting the DB. and why hashing? just a safety precaution.

Step 2: Re-organize project structure

Our app is growing and we need a proper structure to avoid confusion.

So, we'll put resolvers and typeDefs both in separate folders and create an in each one. then you can invoke them as Node modules. .

index.js will look something like this

Alt Text

Step 3: Create a User model

We need a new MongoDB collection for the users.

And we need to update our Todo model as well.

Step 4: Create a Schema and resolvers for User

  1. we will update our typeDefs
  1. update the ApolloServer parameters

Per the documentation: there are a number of ways to handle authentication of users. And we'll be using a token in an HTTP authorization header.

The context object is one that gets passed to every single resolver at every level, so we can access it anywhere in our schema code.

  1. create the user resolvers

In our case, We'll be creating two resolvers. Login & Register.

Register takes a userinput (username, pass,confirmPass, email) and returns the user info with a token.

But, First, We need import jsonwebtoken and bcrypt, So if the userinput is valid ( non-empty fields - some basic validation ), then the password, generate a token for that user.

Finally

Now, We'll update the todo resolvers (createTodo - deleteTodo), So We can control who can create and delete todos.

That's it, I hope you find it easy and simple. If you have any questions, please let me know.
