Description:

graphql 2 rest

GraphQL to REST #





A simple way to convert GraphQL queries to REST in order to use any HTTP client for performing a request.
Usage #
There are 2 main things for working with graphql_2_rest library: GraphQLQueryModel and GraphQLQueryBuilder.

GraphQLQueryModel is responsible for putting arguments in GraphQL query. For example, if you have a query:

const query = '''query {
user(first_name: %arg, age: %arg) {
first_name
last_name
site {
site_name
}
}
}''';

then you need to create next GraphQLQueryModel:
class UserQueryModel with GraphQLQueryModel {
const UserQueryModel(
this.age,
this.firstName,
);

final int age;
final String firstName;

@override
List<String> get arguments => ['"$firstName"', '$age'];
}

GraphQLQueryBuilder will replace all arguments consistently in the query using GraphQLQueryModel. By default, GraphQLQueryBuilder uses %arg mask for arguments, but it can be changed while creating instance of this class.
Finally you can use any HTTP client for performing a request, but the request have to be POST:

final dio = Dio(BaseOptions(baseUrl: 'https://endpoint/'));
const queryBuilder = GraphQLQueryBuilder();
dio.post<dynamic>(
'graphql/',
data: queryBuilder.build(
query,
UserQueryModel('John', 27),
),
);
