Replace the content of the src/graphql/mutations.js file with five steps to exam successTo help you feel best prepared for your exams complete the five-step checklist below, and you will have everything you need to walk into your exam centre fully prepared and ready to tackle your Professional and Advanced Level exams.
The next step is to update our GraphQL queries and mutations to work with the just-created AppSync backend. exports = ) Update GraphQL Queries and Mutations readFileSync ( "jwks.json" ) ) const _ = require ( "lodash" ) Should look like the following, just copy the region and user pool id values.Ĭonst fs = require ( "fs" ) const jwt = require ( "jsonwebtoken" ) const jwkToPem = require ( "jwk-to-pem" ) const jwks = JSON. It is a JSON file and you can locate it at You can find region and userPoolId in your src/aws_exports.js. To verify the token on the Cube.js side, we need to download the public JSON Web Key Set (JWKS) for our Cognito User Pool. The requests to the Cube.js backend with this token. Signs in to our app, we'll request a JWT token for that user and then sign all In our tutorial, we're not going to restrict users to accessĭata, but we'll just authenticate them based on JWT tokens from Cognito. ID, which can then be passed to the data schema as a security context to restrict access to some part The JWT tokens can carry a payload, such as a user The usual flow is to use JSON Web Tokens (JWT) for Model, designed to manage access to the data onĭifferent levels. We're going to use Cognito's identity tokens to manage access to Cube.js and the It will also wire up everything together, so Cognito’s tokens can be used to control the ownership of the dashboard items.Īfter everything is deployed and set up, the identifiers for each resource are automatically added to a local aws_exports.js file that is used by AWS Amplify to reference the specific Auth and API cloud backend resources. The command above will configure and deploy the Cognito Users Pool and the AppSync GraphQL API backend by DynamoDB table.
? Do you want to generate code for your newly created GraphQL API No Delete the provided sample GraphQL schema and replace it with: ? Do you want to edit the schema now? YesĪt this point, your default editor will be opened. ? What best describes your project: Single object with fields (e.g., “Todo” with ID, name, description ) ? Do you want a guided schema creation?

Please select from one of the below mentioned services GraphQL To switch to Yarn, delete node/_modules folder and package-lock.json inside dashboard-folder It is better at managing dependencies, and specifically in ourĬase we'll use some of its features such as
I highly recommend using Yarn instead of NPM while working with ourĭashboard app.
As a prerequisite to this part you need to have an AWS account, so you can use its services.īesides AWS AppSync you can use any other GraphQL server to persist your dashboard data and athenticate/authorize your users.Ĭube.js itself doesn't have any dependencies on dashboard data persistance and it's completely up to your frontend application on how to handle this implementation.
AppSync natively integrates with Cognito and can use its identity tokens to manage the ownership of the data-and in our case, the ownership of the dashboards. It allows us to create a flexible API to access and manipulate data and uses GraphQL as a query language. To store the dashboards, we will use AWS AppSync.
It supports user registration and sign-in, as well as provisioning identity tokens for signed-in users. AWS Cognito User Pool makes it easy for developers to add sign-up and sign-in functionality to web and mobile applications.
We are going to use AWS Cognito for authentication. To do so, we first need to add authentication to our application and then save the users’ dashboard in the database.
We want to let our users create dashboards and not lose them when they change the browser. It is handy for development and prototyping, but is not suitable for real-world use cases. Now we have a basic version of our app, which uses local storage to save charts on the dashboard.
