GraphQlClient

Simple GraphQL client wrapper for .NET.

Installation

The packages are available at nuget.org for installation (see karrocon.GraphQlClient and karrocon.GraphQlClient.Relay).

Examples

Build query strings easily

Supports query string building in an expression-based style:

var queryString = GraphQueryStringBuilder.Build<QueryRoot>(queryBuilder => queryBuilder
                     .AddObjectAs<IEnumerable<Shop>, Shop>(query => query.Shops, shopBuilder => shopBuilder
                     .AddScalar(shop => shop.Name)
                     .AddObjectAs<IEnumerable<User>, User>(shop => shop.Users, userBuilder => userBuilder
                          .IncludeAllScalars()
                          .AddObjectAs<IEnumerable<Address>,Address>(user => user.Addresses, addressBuilder => addressBuilder
                              .IncludeAllScalars()
                          )
                          .AddArgument("age", 18)
                     )
                     .AddArgumentAsVariable("name", "nameVariable")
                )
            );

Relay

It also supports building query strings for Relay-based servers:

var queryString = GraphQueryStringBuilder.Build<QueryRoot>(queryBuilder => queryBuilder
                .AddConnection(query => query.Shops, 10, shopBuilder => shopBuilder
                    .AddScalar(shop => shop.Name)
                    .AddConnection(shop => shop.Users, 5, userBuilder => userBuilder
                        .IncludeAllScalars()
                        .AddConnection(user => user.Addresses, 1, addressBuilder => addressBuilder
                            .IncludeAllScalars()
                        )
                    )
                )
            );

Query all pages at once using Relay

The library features an extension method for graphql-dotnet.IGraphQlClient to query every Relay page at once:

var queryString = GraphQueryStringBuilder.Build<QueryRoot>(queryBuilder => queryBuilder
                .AddConnection(query => query.Shops, 10, shopBuilder => shopBuilder
                    .AddScalar(shop => shop.Name)
                    .AddConnection(shop => shop.Users, 5, userBuilder => userBuilder
                        .IncludeAllScalars()
                        .AddConnection(user => user.Addresses, 1, addressBuilder => addressBuilder
                            .IncludeAllScalars()
                        )
                    )
                )
            );

var result = await client.QueryAllPagesAsync(new GraphQlRequest { Query = queryString });
