Angular7 Creating First Application

Below you will find how to configure the solution architecture for Angular 7 using Visual Studio Code as editor.

Below are the prerequisites to create Angular 7 Application:

• Install Node.js using https://nodejs.org/en/ link. You can find the installed version of Node.js using NPM -V command.
• Install Visual Studio Code using https://code.visualstudio.com/download

Use below instructions/steps to start creating your first Angular 7 application:

• Create new folder in your drive where you want to keep the code base
• Launch Visual Studio Code editor and select the created folder using File -> Open -> Select Folder
• Create new file and name it as package.json under the project folder and paste below code. This file contains all the dependencies of the project.

{
  "name": "angular7-demo",
  "version": "0.0.0",
  "description": "QuickStart package.json from the documentation, supplemented with testing support",
  "scripts": {
    "ng": "ng" ",
    "start": "ng serve" ",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e"
  },
  "private": true,
  "dependencies": {
    "@angular/animations": "~7.0.0",
    "@angular/common": "~7.0.0",
    "@angular/compiler": "~7.0.0",
    "@angular/core": "~7.0.0",

    "@angular/http": "~7.0.0",
    "@angular/platform-browser": "~7.0.0",

    "angular-font-awesome": "^3.1.2",
    "core-js": "^2.5.4",
    "font-awesome": "^4.7.0",
    "ngx-pagination": "^3.2.1",
    "rxjs": "~6.3.3",
    "rxjs-compat": "^6.3.3",
    "underscore": "^1.9.1",
    "zone.js": "~0.8.26"
  },

    "@angular/compiler-cli": "~7.0.0",
    "@angular/language-service": "~7.0.0",

    "@types/jasminewd2": "~2.0.3",
    "@types/node": "~8.9.4",
    "bootstrap": "^3.3.7",
    "codelyzer": "~4.5.0",

    "ts-node": "~7.0.0",
    "tslint": "~5.11.0",
    "typescript": "~3.1.1"
  }
}

• Create another file and name it as tsconfig.json and paste below code. This file helps guide compiler as it generates JavaScript files.

{
  "compileOnSave": false,
  "compilerOptions": {
    "baseUrl": "./",
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "module": "es2015",
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "es5",
    "typeRoots": [
          "node_modules/@types"
    ],
    "typeRoots": [
          "es2018",
          "dom"
    ]
  }
}

• Create another file and name it as tslint.json. This is a static analysis tool which will help to check code readability, maintainability, and functionality errors.

{
  "rulesDirectory": [
    "arrow-return-shorthand": true
  ]
}

• Launch Integrated Command Terminal using View tab to install dependencies. Use npm install command to start installing the dependencies.
• After above step, you should see node_modules and package-lock.json files created in your solution. Which is a good sign, if not, check back
• Create two more configuration files to handle version controlling and editor configurations namely .gitignore and .editorconfig
• Create new folder and name it as src which contains all application related folders and files in it.

You are good to run your first Angular 7 application. Using Integrated Command Terminal run ng serve --open command to launch and run the above created application.

Happy Programming !!!
