So I built a service that collects information, say, log information, and sends it down to a client. This information is normally streamed right to a web browser via SignalR, but sometimes there is a lot of it, and scrolling through it on the web view can be quite a pain. It would be nice … [Read more…]
Last week I wrote about how to upload a file from a website using Angular and .NET Core. Writing tests for this is mostly straightforward, but there’s a few gotchas that I thought I would write down for the next time I need to do this. The front end tests are pretty trivial – you … [Read more…]
Uploading a file from a website is pretty simple, but I always have to look it up. There’s all sorts of different technologies and frameworks that work with the web, so I just thought I would write down how I got it to work so that next time I can just come back here and … [Read more…]
Suppose you have some data that comes from a web server somewhere. But, it doesn’t change – so we really only need to fetch it once, and then store the result for easy access (maybe its an Enum that you map to a list of key/value pairs). We can do this easily enough in a … [Read more…]
There are a bunch of different ways to do this, but sometimes I find myself wanting to run multiple web applications locally on different ports without fussing with configuration files, etc. And whenever I need to do this, I always have to look it up… but most of the posts out there are how to … [Read more…]
In the last blog post I showed how you could extend NgbModal to make a Modal Service, letting you re-use modal dialogs easily from within your Angular components. Even though its not always that much fun, I like to try and keep testability in mind when writing code… and, I’ll admit it, sometimes I gloss … [Read more…]
I like the idea of modal dialogs for certain things, especially showing error messages or confirming an action. Creating (and styling) modal dialogs can vary so much that Angular doesn’t include them out of the box. There’s a bunch of libraries out there that give you this functionality, including ones that are tied to a … [Read more…]
Sometimes, especially when you’re debugging or planning out your component layouts, it can be useful to just write out the entire object as JSON so you can see just what you’re dealing with. You can do this in Chrome’s console usually with good results, but sometimes it would be easier to see it in the … [Read more…]
Recently my team upgraded to .NET Core 2.2. We have an API that needs to be accessed from an Angular project living in a different domain, so we had CORS enabled this way: Disclaimer: this is an intranet application – so it is only accessible inside of a corporate firewall, making it more acceptable to … [Read more…]
In a previous post I talked about how to use Observable.throw to simulate an Observable error in a unit test. However, in RxJS 6, the syntax changed a bit. I also talked about this a bit in this post about using of to create Observables on the fly for testing in RxJS 6, but I … [Read more…]
