Postman is an incredibly useful tool for testing API’s. I’ve been using it for a few years now and have found some features that make it a breeze to work with when it comes to secured API’s. It’s good for handling different environments as well.

Angular routing is pretty nifty. Going into how it works is beyond the scope of this post (and there’s plenty of resources out there doing just that), but suffice it to say if you’re working on an Angular application, you’re using Angular’s routing.
One of the things Angular’s routing does to increase performance is reusing a Component for a route that has already been instantiated. Say you have a Component, “MyComponent”, tied to a route, “/MyPath”. “MyComponent” isn’t created until the user actually navigates to the “/MyPath” route. That makes perfect sense – why instantiate a component that doesn’t need to be used yet? What’s interesting about this design, though, is how parameters factor into it. Let’s say you add a parameter to your “/MyPath” route, making the route “/MyPath/:id”. The first time the user navigates to some version of this route, let’s say “/MyPath/1”, “MyComponent” will be instantiated (with the id parameter set to 1). Then if, without leaving that route, the user changes only the parameter – for example, there’s a link in the component to go to “/MyPath/2”, “MyComponent” will not be recreated. In fact, if not handled correctly, to the user nothing will have changed. It will still look like they’re seeing the “/MyPath/1” version of “MyComponent”. Read more
