> the screen of your app is also a source of asynchrony Exactly! That’s why wrapping a “dialog” or “form” or “screen” into a Promise is such a powerful technique. When the user closes the dialog, the promise resolves with a result (e.g.

I’m afraid htmlx might be repeating the same mistake that CORBA and DCOM made decades ago: pretending that latency doesn’t matter. Yes you could make a CORBA or DCOM object almost indistinguishable from a local object, except for the latenc

For what it’s worth, we implement tests in the client language (C# in our case) and just call the stored procedures/views (in SQL Server) as any client would. Most tests are written so that they rollback after execution, and to tolerat

On the other hand, there are good reasons to put logic in the database, chiefly: - Performance - Consistency - Security Basically, you want to construct a public API in the form of stored procedures, functions and views, and then funnel all

MobX is fantastic! But you do have to change your philosophy quite a bit compared to what you would do in vanilla React - namely you need to displace most of your state management to the outside of the components. Once you do that, React be

> HOC's have a bunch of downsides, imo the most obvious one is the props; you need to pass the previous props, and merge in the new ones. Render props (aka. "function as children") are much more free form than HOCs - they

Most importantly: hooks make functions that look pure actually impure. Before hooks, if you wanted to call a functional React component, you could reasonably assume it's pure - it depends just on props and nothing else. Only when tryin

> hooks form part of the input to the hook/render function. They are input, but they are not input parameters. A function is pure if it returns same result for same input parameters. Hooks make it possible to return different result

I fully agree that impure views are a path to madness, but you don’t have to abandon React to have pure views. React components can, and I would argue in vast majority of cases should, be pure functions. You just need to displace state mana

You return a different result (i.e. the Promise resolves to a different result). The calling code can then decide what to do with it.

There is another use case for async in client-side JavaScript that often gets overlooked: modeling the flow of UI. So, let's say you need to show a "dialog" which, upon exit, should execute a piece of code (e.g. to show anoth

But careful! In the concurrent environment, separate queries may need a higher transaction isolation level to mean the same thing as one query.
