Validating Azure Functions CRUD operations

Question

I have just started to look at Azure Functions and one of my biggest concerns currently is validation.

I have only really looked at the CRUD operations so far, but there doesn't look like a way to easily validate data coming from the request or into the storage.

I have found this poco-validation and thought it might be useful.

I know this is kind of and open ended question but I'd be interested to see what others was doing for validation.

Answer 1

We recently added Function Filters to the underlying WebJobs SDK but that feature isn't fully exposed yet in Azure Functions (see issue here). Related to this, we're also considering support for validation annotations to be applied to your POCO types (issue here).

Until the above issues are addressed, we realize the story for validation isn't great. The recommended approach is to perform required validation in your function code calling out to shared validation helpers/code as needed.
