Query GraphQL with LINQ

I’m not sure whether this feature belongs to this project or not but I wanted to share my suggestion and a prototype I built.

Problem:

Querying a GraphQL endpoint requires writing a string query that is neither strongly typed, nor checked by the compiler. As LINQ solved the same problem it would be cool to do use LINQ for GraphQL queries too.

Solution

I have built a prototype called GraphQLinq that generates strongly typed client from GraphQL API and allows writing graphQL queries like this:

var spaceXContext = new QueryContext();
var companySummary = spaceXContext.Company().Select(c => new CompanySummary
{
    Ceo = c.Ceo,
    Name = c.Name,
    Headquarters = c.Headquarters
}).ToItem();

This will generate a GraphQL query, run it and deserialize response in the corresponding class.

It supports quering nested properties and you can find more examples in the Readme of the project.

We’re definitely interesting in anything GraphQL and .NET, thanks for opening this and for the discussion. Please don’t hesitate to ping me or the rest of the team for anything.

We can move to the project repo for more details. I opened it here because EF Core 6 plans mentioned GraphQL and wanted to bring the project to the ef team’s attention.
