/**

|
* Returns a query document which adds a single query operation that only
|
||
|
|
* spreads the target fragment inside of it.
|
||
|
|
*
|
||
|
|
* So for example a document of:
|
||
|
|
*
|
||
|
|
* ```graphql
|
||
|
|
* fragment foo on Foo { a b c }
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* Turns into:
|
||
|
|
*
|
||
|
|
* ```graphql
|
||
|
|
* { ...foo }
|
||
|
|
*
|
||
|
|
* fragment foo on Foo { a b c }
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* The target fragment will either be the only fragment in the document, or a
|
||
|
|
* fragment specified by the provided `fragmentName`. If there is more than one
|
||
|
|
* fragment, but a `fragmentName` was not defined then an error will be thrown.
