- Created by Facebook in 2012 - No need to call several APIs - Get many resources in a single request - Ask for what you need, get exactly that - Self documented - With a type system A query language for your API source: Michael Poirier-Ginter What is GraphQL

• a read only stream of data • shared cache between components (standard & custom) • reactive to changes outside of the component’s scope • no Apex with standard Lightning Data Service Wire Adapters • just import it and use it 🎉 What is a Wire Adapter

A GAME CHANGER What is the GraphQL Wire Adapter

Query any list of records you want - Order them - Group them - … Easy to use because - you don’t need to write any Apex - respects user Field Level Security - use the same shared Lightning Data Service cache Get for a custom component - a list of all contacts for a given account - a search page - a hierarchy of records - one specific record with filters, without knowing its Id at first - … What is the GraphQL Wire Adapter

- An easy to use local client to test your queries - Get an access token - for instance use sf org display - Use the following url: - https://{MyDomainName}.my.salesforce.com/services/data/v{version}/graphql - Then you can: - query - autocomplete - look at API documentation (display existing fields, available formatting etc) https://ww.altairgraphql.dev Connect to GraphQL API Altair GraphQL Client
