Integrating Cosmos DB with OData (Part 3)

Sometimes requiring to build an entire ASP.NET Core application just for the purpose of exposing a RESTFul API endpoint to give your API consumers the ability to query, filter and order the data could be a bit of an overhead, especially if you are not planning on adding in any additional business logic between your data and it’s consumers.

Experimenting with OData in ASP.NET Core 3.1

A lot of developers have asked me recently about OData compatibility with ASP.NET Core 3.0 and again with .NET Core 3.1 after it’s very recent release.
This demand became more and more critical with the recent announcement from the .NET team around .NET Core 2.2 reaching the end of its life on Dec 23rd of this year.

Optimizing Web Applications with OData $Select

OData as an API technology comes in with so many options that gives API consumers the power to shape, filter, order and navigate through the data with very few lines of code.
In my previous articles I talked in details about how to enable OData on your existing ASP.NET Core API using the EDM model,

Customize Control Information for full metadata requests in odata.net

Background
OData supports three metadata levels for the JSON format, namely –

No Metadata
Minimal Metadata
Full Metadata

No Metadata as the name suggests does not include control information other than nextLink and count. Minimal metadata responses usually include context, etag,

Using SkipToken for Paging in Asp.Net OData and Asp.Net Core OData

Loading large data can be slow. Services often rely on pagination to load the data incrementally to improve the response times and the user experience. Paging can be server-driven or client-driven:
Client-driven paging
In client-driven paging, the client decides how many records it wants to load and asks the server for that many records.

Integrating Cosmos DB with OData (Part 2)

In the first article of this series, we talked about integrating Cosmos DB with ASP.NET Core application powered by OData using a pre-built solution that was using Cosmos Client to run full CRUD operations.
But that’s not the only way we can work with Cosmos DB from ASP.NET Core –

Integrating Cosmos DB with OData (Part 1)

We talked in previous articles about the pluggability of OData with any storage technology regardless of its schema, whether it’s a SQL-based storage, NoSQL, In-Memory or simply a file on a hard-drive.
This power of OData enables developers to work with powerful,

Enabling Pagination in Blazor with OData

Summary
We talked in a previous article about enabling OData in your existing ASP.NET Core API using EDM.
One of the biggest advantages of following that method is to be able to take advantage of functionality such as count to enable an on-demand function in almost every web application such as navigation.

Simplifying EDM with OData

Summary
In a previous article, I talked about how you can leverage the power of OData with your existing ASP.NET Core API to bring in more features to your API consumers.
But there are different ways you could enable OData on your existing API that are just as simple but offers more powerful features than overriding your existing routes and enabling dependency injection.
