If you have multiple accounts on Github (or whatever git repository host you use) then it can be a little confusing knowing which user you are committing as and how to switch to a different user. In this post I'll show you an easy way to switch between users from the command line.
I just had the awesome opportunity to TA and sit in on a 2-day Angular 2 course instructed by one of the top teachers in the web development world and the hungry mind behind One Hungry Mind Blog, Lukas Ruebbelke (@simpulton). It was especially humbling because his eggy bookmarks course was one of the very first times I really dug in and started writing Angular code. It felt like meeting a childhood hero or Santa Claus. I had spent so much time watching his videos that it was surreal to meet him in person, and yes he is really that goofy and funny in real life. haha. Anyway, even though I have been using Angular 2 for a little while now and the course was aimed more for beginners, I still took about 4 pages of notes and learned a ton while I was there. Plus, it was great to get a refresher/confirmation on some basic concepts and some new perspective on how to think about certain other things. In this post I've written a bullet point list of some after-the-fact thoughts while looking back at the notes I took during the lectures. Enjoy!
As you may have guessed from the title, this post is all about understanding what selectors are in an Ngrx Angular 2 application and why one should want to use them. I'll admit it; for a while I didn't use selectors at all. The truth is that you don't *need* them to get a basic project up and running with Ngrx (and that's why I don't talk about them in my Getting Set Up With With Ngrx blog post), but as your application grows along with your understanding of Ngrx you may eventually want to refactor your code and the way you select data from the state to improve your project's consistency and prevent unnecessary duplication. So without further ado, let's talk about selectors!
If you've taken a look at some open source projects that use Ngrx such as example-app, ngrx-examples , or angular-nye-advanced-ngrx then you may have noticed that they have an interesting way of defining Action types. In this post I'll go over why we use the "type" method and why we construct the Action strings in this specific style. Big thanks to Xavier, @xlozingues, for staying at the office late on a Friday to help me understand this. ?
I was recently at a Meetup watching over the shoulder of web development and Angular guru, Daniel Zen. I saw him working in his command line and he would easily open the current directory in WebStorm by typing, "webstorm ." into the terminal window. However, when I tried I would get the error message, "-bash: webstorm: command not found". This post is about installing the webstorm command line tool so that you can use this easy, nifty project opening shortcut.
