Binding converter that takes very long RRS feed

  • Question

  • How would I create a binding converter, that takes some time to extract file properties or a thumbnail?

    I am having trouble getting the async APIs to work with converters who cannot handle Promises and expect the return value to be fully calculated already.

  • Hi Phil,

    Correct, the converter is not Async.  You should pre-process the data before binding if you need that functionality instead of trying to do it on the fly.
