GraphQL (the new Salesforce reference API?!) This document discusses GraphQL and the GraphQL Wire Adapter in Salesforce Lightning. It provides an introduction to GraphQL, demonstrates how the GraphQL Wire Adapter can be used to query data without writing Apex code, and discusses resources for learning more about GraphQL and the Wire Adapter. The demo section shows how the Wire Adapter can be used to filter, order, and query relationships between objects.

4. GraphQL

5. - 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

6. - 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 🎉

8. 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 with filters
- a hierarchy of records
- one specific record with filters, without knowing its Id at first
- …

9. 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)

15. Mutations
Create and update records in one call

16. - Backward pagination
- No mutation for the Wire Adapter (on the roadmap), only in the UI API
- Filter with no value
- Actually more GraphQL than Salesforce “issue”
