GnG Integration challenge III | PVT/Black Oil integration

Welcome to the GnG Integration challenge III | PVT/Black Oil integration Challenge. In this challenge, we are looking for you to integrate the backend API with the existing Angular 2+ Application.

Technology Stack

• NodeJS
• Angular 7
• JavaScript
• REST

General Requirements

Data Loading & Alerts

• Use loading animation effect to show the progress when loading data.
• Sanck-bar/toast should be used to show the error, success & warning messages when data is loaded from API. It shouldn't be shown for every successful API call, use your best judgment to show these.

Code Quality

• Reuse the existing code, components, CSS, js, etc as much as possible instead of duplicating the code.

Code formatting

• Make sure code is well documented, all classes, methods, variables, parameters, return values must be documented in every single code file, and appropriate inline comments should be provided too where the code is not straightforward to understand.
• Please use clean INDENTATION for all HTML code so future developers can follow the code.
• Use appropriate linter to validate your code.

Framework specific

• Use Observable & Observable.subscribe() method wherever applicable. You may refer this: https://angular.io/tutorial/toh-pt4#subscribe-in-heroescomponent
• Use Dependency Injection coding pattern.
• ng build should work without throwing any error.

HTML Specific

• HTML should be valid HTML5 compliant.
• All HTML code naming should not have any conflicts or errors.
• Element and Attribute names should be in lowercase and use a '-' or camel naming to separate multiple-word classes (i.e.. 'main-content', or 'mainContent)
• Use semantically correct tags- use H tags for headers, etc. Use strong and em tags instead of bold and italic tags.
• No inline CSS styles- all styles must be placed in an external stylesheet.

CSS Specific

• Use CSS3 Media Queries to load different styles for each page. Do not build a different page for different device/layout.
• You may use SCSS in the project.

Platform

• Desktop: Chrome latest, Firefox latest (Mac & Windows), Safari latest (Mac), IE11+ (Windows), MS Edge
