GraphQL.OData

C# Library for nesting an OData API within a graphql schema, Intended to be used with the GraphQL package on nuget. A sample project is included which creates a graphql server with the MS Graph api nested within

Usage

Within Startup.ConfigureServices add

services.AddGraphQLOData();

Within your Query constructor classes add ODataResolver as an injected parameter, then add the following replacing everything between

this.AddField(
    new FieldType
    {
        Name = "<the root endpoint which you will be nesting under>",
        ResolvedType = oDataResolver.GetQueryType(
            "<the prefix which will be added to all types>",
            "<the base url which can be used to fetch the metadata and call the api>"
        ),
        Resolver = oDataResolver
    }
);

This will add a new object type to your query with all EntitySet and Singleton elements on it

Within your Mutation constructor classes add ODataResolver as an injected parameter, then add the following replacing everything between

this.AddField(
    new FieldType
    {
        Name = "<the root endpoint which you will be nesting under>",
        ResolvedType = oDataResolver.GetMutationType(
            "<the prefix which will be added to all types>",
            "<the base url which can be used to fetch the metadata and call the api>"
        ),
        Resolver = oDataResolver
    }
);

This will add a new object type to your mutation which currently only has a placeholder
