We will install the requirements for development: Visual Studio Code and NodeJS and setup sample Angular project.
Dependencies2:00
To make sure we are having the same dependencies:
- delete package-lock.json file
- delete node_modules
- replace package.json content with the following and then run "npm install" :
{

Overview0:14
Frontend architecture1:21
We will describe the frontend architecture and components which we will develop.
Website mockup7:24
We will define interfaces and mockup a simple website design with implementation using Bootstrap.
JavaScript requires jQuery0:12
PollCreate component view5:06
We will develop PollCreate component (view) which will be responsible for handling input form data, for creating polls.
PollCreate component logic6:52

Description

Over 39,000 happy students from 136 countries!

Hello! Welcome to the Complete Blockchain Web Application Development course, the only course you need to build decentralized web applications.

What does blockchain have to do with web development?

Blockchain technology has become synonymous with cryptocurrencies and token crowd sales. However, there are a variety of blockchain applications that could be applied to web development. Blockchain technology is one of the latest trends in the web development industry. There has been a lot of hype surrounding this buzzword, and most people are still wondering what the real use cases of blockchain technology are, and if they can actually apply it to make profitable business models.

You will learn all fundamental aspects of creating and connecting blockchain application to website and interacting with it.

Course is divided into 3 main sections:

Frontend application - developed in Angular, completely decoupled from blockchain.
Smart Contract and blockchain - learning the fundamentals of developing, deploying (locally) and interacting with smart contract.
Middleware - The most important "glue" between the frontend and smart contract.

Hurry though… the price might change at any point

And if you don't think it live up to promise I've made you...

Or you think you cannot develop your own blockchain web app in the end...

There is a 30-Day Money-Back Guarantee...

All risk is lifted from your shoulders and placed squarely on mine. Join the BEST Blockchain Web Development on Udemy today!

See you on the inside!
