GraphQL

Parcel supports importing GraphQL queries defined in a separate file into JavaScript via the @parcel/transformer-graphql plugin. When a .graphql or .gql file is detected, it will be installed into your project automatically.

Example usage

#

GraphQL files are imported into JavaScript as a string, which you can send to a server directly or use with whatever GraphQL library you like.

app.js:
import query from './query.graphql';
query.graphql:
{
user(id: 5) {
firstName,
lastName
}
}

Dependencies

#

Parcel also supports importing fragments defined in separate files into another GraphQL file using a special comment syntax. These will be bundled together into a single GraphQL query and returned to your code as a string.

You can either import all fragments from a file:

# import "fragments.graphql"
# import * from "fragments.graphql"

or list the specific fragments you wish to import:

# import UserFragment, AddressFragment from "fragments.graphql"

Here is a full example showing how to use imports as part of a larger GraphQL query:

query.graphql:
# import UserFragment from "user.graphql"
# import "address.graphql"

query UserQuery($id: ID) {
user(id: $id) {
...UserFragment
address {
...Address
}
}
}
user.graphql:
fragment UserFragment on User {
firstName
lastName
}
address.graphql:
fragment AddressFragment on Address {
city
state
country
}
