SmartGraphQLClient 1.0.0

SmartGraphQLClient

Back-to-back GraphQL client using Linq-syntax

Install NuGet package

Using Package Manager:

Install-Package SmartGraphQLClient

or

Using .NET CLI:

dotnet add package SmartGraphQLClient

Usage

1. Add required services to DI

using SmartGraphQLClient;

services.AddSmartGraphQLClient();

2. Write GraphQL-request with Linq-syntax

using SmartGraphQLClient;

GraphQLHttpClient client = ... // from DI

var users = await client.Query<UserModel>("users")
    .Include(x => x.Roles)
        .ThenInclude(x => x.Users)
    .Where(x => x.UserName.StartsWith("A") || x.Roles.Any(r => r.Code == RoleCode.ADMINISTRATOR))
    .OrderBy(x => x.Id)
      .ThenByDescending(x => x.UserName)
    .Select(x => new 
    {
        x.Id,
        Name = x.UserName,
        x.Roles,
        IsAdministrator = x.Roles.Any(r => r.Code == RoleCode.ADMINISTRATOR)
    })
    .Skip(5)
    .Take(10)
    .Argument("secretKey", "1234")
    .ToListAsync();

Explanation

When you call materializing method (ToListAsync(), ToArrayAsync(), FirstAsync(), etc.), the GraphQLHttpClient will build a string query and send it to the GraphQL-server, get a response and materialize the result.

Query-string from example:

{ 
    users (
      where: {
        or: [ 
          { userName: { startsWith: "A" } }
          { roles: { some: { code: { eq: ADMINISTRATOR } } } }
        ]
      }
      order: [
        { id: ASC }
        { userName: DESC }
      ]
      skip: 5
      take: 10
      secretKey: "1234"
  ) {
        id
        userName
        roles {
            code
            name
            description
            id
            users {
                userName
                age
                id
            }
        }
    }
}

More examples

See more examples in unit-tests directory:

1. more requests (ToListAsync(), ToPageAsync(), FirstOrDefaultAsync())
2. attributes (GraphQLEndpointAttribute, GraphQLIgnoreAttribute, GraphQLPropertyNameAttribute)
3. authorized graphql-http-client (IGraphQLAuthorizationService<> for providing tokens in runtime and cache tokens)
4. and more

Compatibility

Requests were tested on HotChocolate GraphQL-server. See their documentation.
