Fast JSONCache updates now active for improved responsiveness
I recently posted about Initializing page JavaScript from the JSONCache. Now I’m pleased to announce that you can also get updated copies of the IJSONRequestCache, to make it easier to update your page.
Brad Crittenden and I started work on this at the Dublin Thunderdome, and it’s finally been deployed. What this means is that for basically any page on Launchpad, you can append /++model++ to the URL, to get a fresh copy of the IJSONRequestCache. With ++model++, a change will typically require only two roundtrips; one to make a change, and one to retrieve an updated model. Future work may reduce this to a single roundtrip.
Why ++model++, not ++cache++? Cache is a really poor name for what the IJSONRequestCache is. Rather than providing fast access to whatever data has been previously retrieved, it is a complete collection of all the relevant data.
In Launchpad, the IJSonRequestCache is associated with the view, so we’re trying to rebrand it as the “view model”. This may seem strange from an MVC (Model, View Controller) perspective, but MVC can be recursive. A view may use a model to render itself.
