AngularJS Application Calling Order

Here's the calling order:
  1. app.config()
  2. app.run()
  3. directive's compile functions (if they are found in the dom)
  4. app.controller()
  5. directive's link functions (again, if found)
Here's a simple demo where you can watch each one executing (and experiment if you'd like).
Run blocks - get executed after the injector is created and are used to kickstart the application. Only instances and constants can be injected into run blocks. This is to prevent further system configuration during application run time.
Run blocks are the closest thing in Angular to the main method. A run block is the code which needs to run to kickstart the application. It is executed after all of the service have been configured and the injector has been created. Run blocks typically contain code which is hard to unit-test, and for this reason should be declared in isolated modules, so that they can be ignored in the unit-tests.

[Advance Java] Difference Between Apache and Tomcat

Image
The most prevalent use of the internet today is browsing. People all around the world find information by accessing data from other computers through their browser; but beyond that, people know very little. In order to communicate with the host computer, the browser would need to request pages from a http server that is run on the host computer. It would then be responsible for finding and providing you with the right pages. An excellent and very popular web server around today is the Apache web server. It allows people who want to set-up their own web server to do so with very little trouble. Installing the Apache web server is the most basic thing you can do to support html and other related software. The next step is to install more software that complements the web server like PHP or Tomcat. Tomcat is another piece of software that is meant to enhance the usability and interactive experience that users experience with your website. Because Tomcat is also a serv...

Setting ESLint on a React Typescript project

The main goal of this tutorial is to set up step-by-step and explain every line added or executed, instead of just giving you a bunch of files with a lot of configurations and expecting that you will be able to understand what and how things are happening. So, let’s start! Prerequisites Note: You need Node version >= 10 installed. So, if you don’t have it, please go to the NodeJS website, and download and install it on your local machine. ( https://nodejs.org/en/ ) Step 1: Create a React Project with Typescript The following command will create a project inside a folder  my-app . On the terminal, run: npx create-react-app my-app --template typescript Step 2: Removing the pre-set ESLint configuration from React project React comes with an eslint configuration pre-setted. Let’s rem...
