Fragments
The fragment
keyword lets you define new fragments that can be referenced
in a query, per the Fragments section of the GraphQL specification.
Fragments allow for the reuse of common repeated selections of fields, reducing
duplicated text in the DQL documents. Fragments can be nested inside fragments,
but no cycles are allowed in such cases. For example:
curl -H "Content-Type: application/dql" localhost:8080/query -XPOST -d $'
query {
debug(func: uid(1)) {
name@en
...TestFrag
}
}
fragment TestFrag {
initial_release_date
...TestFragB
}
fragment TestFragB {
country
}' | python -m json.tool | less
Note GraphQL+- has been renamed to Dgraph Query Language (DQL). While
application/dql
is the preferred value for the Content-Type
header, we will continue to support
Content-Type: application/graphql+-
to avoid making breaking changes.
