Q9: What are GraphQL Aliases and when should you use them?
Aliases allow you to rename the result of a field in a query. They are essential when you need to query the exact same schema field multiple times with different arguments in a single request.
Querying with Aliases
query GetTwoUsers {
admin: user(id: "1") {
name
}
guest: user(id: "2") {
name
}
}💡 The aliases
admin and guest differentiate the two user field calls in the JSON response.Key Takeaways
- Aliases prevent JSON property collision when querying a field multiple times in one operation.
