TMS Software provides the more complete and extensive Delphi library to work with GraphQL.

What is GraphQL

GraphQL is a specification for a query language that is widely used specially in client/server communication, makes it easy and standard for clients to gather server data in a structured way. In case you want to know more I have written an extensive article about GraphQL and Delphi in my personal blog. And of course, there is the official GraphQL page.

About GraphQL for Delphi

To work with GraphQL in Delphi there is our library GraphQL for Delphi. Lots of features are provided, you check more details in the full GraphQL for Delphi documentation page, and as a small illustration about what it is, you can define document schemas in GraphQL language specification, like this:

type Query {
    hello(name: String!): String
} 

procedure TWebModule1.GraphQLSchema1InitSchema(Sender: TObject; Schema: TSchemaDocument);
begin
  Schema.SetResolver('Query', 'hello', function(Args: TFieldResolverArgs): TValue
    begin
      Result := 'Hello, ' + Args.GetArgument('name').AsString;
    end
  );
end;

Once you have your server up and running, your clients can invoke data from your server using a query language that matches the server schema you defined:

query {
  hello(name: "World")
}

And this is the result they will get:

{
  "data": {
    "hello": "Hello, World"
  }
}

Delphi 12 support and more

In the recently release version 1.4 of GraphQL for Delphi, we added support for Delphi 12. You can now use the library with the latest and more modern Delphi version available.

We also added several improvements, like support for type extensions in GraphQL parser, and support for TMS Sparkle - you can now create GraphQL servers using Sparkle technology which is widely supported by TMS, fast, reliable and low-memory consuming.

For a full list of the changes, please refer to the Release Notes topic of documentation.
