# dropUnusedDefinitions
|
|
|
|
Given an operation document and an operation name, this function will return a
|
|
new document with only the definitions required for the operation name provided.
|
|
|
|
If the provided operation name doesn't match any operation in the document,
|
|
`dropUnusedDefinitions` will return the original document.
|
|
|
|
## Usage
|
|
|
|
```ts
|
|
import { dropUnusedDefinitions } from "@apollo/utils.dropunuseddefinitions";
|
|
|
|
const operation = parse(`#graphql
|
|
query Drop { ...DroppedFragment }
|
|
fragment DroppedFragment on Query { abc }
|
|
query Keep { ...KeptFragment }
|
|
fragment KeptFragment on Query { def }
|
|
`);
|
|
const keepOperation = dropUnusedDefinitions(operation, "Keep");
|
|
/**
|
|
query Keep {
|
|
...KeptFragment
|
|
}
|
|
|
|
fragment KeptFragment on Query {
|
|
def
|
|
}
|
|
*/
|
|
```
