In this tutorial, we are going to create a CryptoCurrency Price Update website using Wix Code. Wix Code is a new advanced feature added to the Wix platform that makes it easier to create custom functionalities for your Wix website. As you may already know Wix is a website builder that lets you create a website from scratch without writing any code.

Quoting the Wix Code website:

“Wix Code makes it easy to build web applications and robust websites. It’s serverless, hassle-free coding. Set up database collections, create content-rich websites, add custom forms and change site behavior with our APIs.”

Wix code, however, was created to target developers who are willing to customize their website beyond the simple drag and drop and ready-made widgets already created by Wix. With Wix code you have full control of your website, you can create custom widgets and add custom behaviors as you desire. Read more about Wix Code here

We are going to take advantage of the Wix Code API in this tutorial to query a third party API and display data dynamically. We will build a Cryptocurrency app that will enable a user to keep track of their favorite Coins by search and also display the top 10 performing cryptocurrencies.

So to get started, you need to create an account on Wix, visit the Signup page to create an account. After that create a new site by hitting the plus icon on the top right corner of the page.

Creating a new Wix site

Which will take you to a new page asking, what kind of website do you want to create? You can choose any option you want there. I chose business.

Creating a Wix site, what kind of website do you want to create?

And then it takes you to the next page where you will be asked to choose how you want to create your website. To be able to use Wix code you have to choose to create your website with Wix editor.

Choose how you want to create your Wix site

And then on the next page, you will be asked to choose a template for your website. You can choose to either create with one of the existing templates or choose to start yours from scratch by choosing the blank template.

On any template you decide to choose, just click on edit so we can start developing our app. You can find edit when you hover over any of the templates. Upon clicking it will take you to the Wix website editor.

Choosing and Editing a Template in Wix

We can now start customizing our chosen template. We will add some important HTML elements.

We also need to enable Wix Code on this template. To do so, we click on Tools and then enable the Developer Tools, which is disabled by default.

Enabling the Wix Code Developer Tools

So the first element we need to add to the page is an input control, this is where the user will type in the name of the cryptocurrency they want to keep track of, and then search for its information using the CoinMarketCap API. To add that navigate and click on plus, which will open a panel with lots of HTML elements that you can use on your page. To add an element to your page, you can either drag and drop it anywhere on your page or double-click on it.

Adding an HTML element to your page in Wix

As you can see the input element gets assigned an ID which must always be unique. We will use the ID to interact with this Input element, later on, to get the value of the user input and then pass it on to the CoinMarketCap API. Let’s change the name of the Input element to something more friendly. Follow the instruction as in the image below.

Changing the ID of an HTML element in Wix Code

Next, let us place a Button beside the input box which will initiate the search when the user clicks on it. We can place a button on the page by repeating the same steps we used to add the input box into the page. We can change the text of the button to Search and also give it an ID of search. After making the changes, my page now looks like this:

Adding a Button to a page in Wix

Later on, we will register an onClick event handler on this button, such that when a user clicks on it, it will initiate a Wix Code function that we will write. This function will search the CoinMarketCap API for any valid currency value you type into the Input element and then retrieve its information and then display it to the user.

But before doing that we need to add another HTML element to the page, a Text element where the result of the search will be displayed. So go ahead and click on the Plus icon again, navigate to Text. I have inserted a paragraph on the page, changed the ID to searchResult and also edited the text content and gave it a simple title of Search Result.

Insert a Text to display search result in Wix Code

This concludes the design and layout of our page and now we can start coding the main logic of the site which is to interact directly with the CoinMarketCap API. You can get an overview and explore the CoinMarketCap API more here. To preview your design you should click Save on the navigation bar before clicking Preview.

Next, We will create a method called getCoinInfo()

With Wix Code it is easy to add a Backend code, you can write functions that you would rather have to write in Backend programming languages like PHP, Python or Ruby.

To begin to write a backend code, navigate to the Arrow function in the footer of the page as shown in the image below.

Adding Backend Code to a Wix Code Website

Once you click on Add a new Web Module you will be given a name suggestion of aModule.jsw I renamed mine to apiModule.jsw, rename the module and hit enter. Once you hit enter you should be shown a code editor page that looks like this:

Creating a Backend Module in Wix Code
import {fetch} from 'wix-fetch';

export function getCoinInfo(currencyName) {
const url = 'https://api.coinmarketcap.com/v1/ticker/' + currencyName + '/';

return fetch(url, {method: 'get'})
.then(response => response.json())
}

With the first import statement, we’re making sure that fetch is imported from the wix-fetch package. With fetch, we are able to initiate an HTTP call needed to retrieve information from the external API. The fetch function is then used within the function getCoinInfo to initiate an HTTP GET request to the API endpoint. The fetch function accepts/expects two parameters:

  • The first parameter is a string containing the URL of the API endpoint.
  • The second parameter is a configuration object in JSON format. In our specific case, this object is containing the property method which is set to string ‘get’ which simply means, we’re initiating an HTTP GET request.
  • Fetch is returning a promise so we can use method chaining and add a .then() to retrieve the value being returned by fetch.

We created a URL string, the base URL, which is passed into the fetch function call, the function getCoinInfo is expecting to get the name of the cryptocurrency as an input parameter. The complete URL is built by concatenating the base URL endpoint https://api.coinmarketcap.com/v1/ticker/ with the currency name. Read more about wix-fetch here. It’s just an extension of the JavaScript fetch API.

Writing a custom function in Wix code editor and navigating back to the Website

Next, we will use the backend code we have just created and then connect it with Search button we created earlier. We want the backend code to run when a user types in the name of a currency in the input element and clicks on the search button. To make this work, we will register an onClick event on the search button. Select the button and then in the properties panel click on the plus icon opposite the onClick event listed there as shown in the image below:

Creating an onClick event in Wix Code

We will make use of the function getCoinInfo in the code editor that opened after clicking on the plus icon of the onClick event. Insert the following import statement first at the top of the editor.

import {getCoinInfo} from 'backend/apiModule';

Now, we can use the getCoinInfo() function on the frontend side by simply calling it inside the search_click() function created for the onClick event of the search button.

import {getCoinInfo} from 'backend/apiModule';

export function search_click(event, $w) {
getCoinInfo($w('#currencyName').value)
.then(response => {
$w('#searchResult').text = "Name: " + response[0].name + "n"

  • "Symbol: " + response[0].symbol + "n"
  • "Price (USD): " + response[0].price_usd;
    });
    }

First we get the value of the text input from user, which is the name of the currency that the getCoinInfo() function expects, the javascript’s fetch api responds with a promise so we use method chaining to apply the then() which is where we retrieve the currency info.

After writing this code, you can hit save and then preview to see your site up and running.

Here’s the result after testing it:

Query an API with Wix Code

You can display more results from the API by simply adding from the list on CoinMarketCap API .

We can further improve the app by adding another function to get the first 10 currencies from the Coin Market Cap API. This will be displayed directly under the search result. Before proceeding to write the function, let’s add another Text element and then give it an ID of coinList. After that, navigate to the Backend/apiModule.jsw file and then add the function there.

export function getTopCoins() {
const url = 'https://api.coinmarketcap.com/v1/ticker/?limit=10';

return fetch(url, {method: 'get'})
.then(response => response.json());
}


And then navigate back to Home. On the home do the following, Choose the Coin List which should have coinList Id and then navigate to the onViewportEnter event, click on the plus icon, which will create a new function in the frontend editor. And then import the getTopCoins()  from the backend.

Adding a function that executes on page load in Wix Code

After adding the content of the function for the onViewportEnter event, my code looks like this:

Adding a function that executes on page load in Wix Code
export function page1_viewportEnter(event, $w) {
getTopCoins().then(response => {
$w('#coinList').text = "Name: " + response[0].name + "t t"

  • "Symbol: " + response[0].symbol + "t t"
  • "Price (USD): " + response[0].price_usd + "n n"
  • "Name: " + response[1].name + "t t"
  • "Symbol: " + response[1].symbol + "t t"
  • "Price (USD): " + response[1].price_usd + "n n"
  • "Name: " + response[2].name + "t t"
  • "Symbol: " + response[2].symbol + "t t"
  • "Price (USD): " + response[2].price_usd + "n n"
  • "Name: " + response[3].name + "t t"
  • "Symbol: " + response[3].symbol + "t t"
  • "Price (USD): " + response[3].price_usd + "n n"
  • "Name: " + response[4].name + "t t"
  • "Symbol: " + response[4].symbol + "t t"
  • "Price (USD): " + response[4].price_usd + "n n"
  • "Name: " + response[5].name + "t t"
  • "Symbol: " + response[5].symbol + "t t"
  • "Price (USD): " + response[5].price_usd + "n n"
  • "Name: " + response[6].name + "t t"
  • "Symbol: " + response[6].symbol + "t t"
  • "Price (USD): " + response[6].price_usd + "n n"
  • "Name: " + response[7].name + "t t"
  • "Symbol: " + response[7].symbol + "t t"
  • "Price (USD): " + response[7].price_usd + "n n"
  • "Name: " + response[8].name + "t t"
  • "Symbol: " + response[8].symbol + "t t"
  • "Price (USD): " + response[8].price_usd + "n n"
  • "Name: " + response[9].name + "t t"
  • "Symbol: " + response[9].symbol + "t t"
  • "Price (USD): " + response[9].price_usd + "n n"
    });
    }


This function is displaying all the 10 currencies that was requested from the CoinMarketCap API in the backend code and function getTopCoin() through this url https://api.coinmarketcap.com/v1/ticker/?limit=10.

The final output looks like this:

Query a third party API with Wix Code (Result)
Update

Due to high demand from our readers, we’ve extended the app further and made the UI even better, but to do that. We wanted to add images of the currencies, but Coin Market Cap API does not provide images for these currencies so we had to query another API to get the images of the currencies. Here’s how we did that:

Navigate back to the Backend/apiModule.jsw file and add this code to query the CryptoCompare API. The API has an endpoint for ImageUrl for the images/logo of each of the currencies. You can navigate here to see the Logo of Bitcoin for example.

export function getImageFromCryptoCompare() {
const url = 'https://min-api.cryptocompare.com/data/all/coinlist';

return fetch(url, {method: 'get'})
.then(response => response.json());
}

Import the backend function into the frontend code editor. And then Add the functions to display the data.

import {getImageFromCryptoCompare} from 'backend/apiModule';

Navigate to the Home and then Add a Repeater from the Lists & Grids.

Adding and displaying data with Repeaters in Wix Code

You have to add a single repeater for each of the ten coins. And then give each of the HTML text elements a unique Id. The code to interact with the repeaters should be placed in $w.onReady() function since we want the function to execute immediately the page loads. Each section of this code represents data being displayed on each of the repeaters.

$w.onReady(function () {
getTopCoins().then(response => {
getImageFromCryptoCompare().then(resp => {
$w('#image1').src = 'https://www.cryptocompare.com' + resp.Data[response[0].symbol].ImageUrl;
$w('#coin1').text = response[0].name;
$w('#text23').text = response[0].price_usd;

$w('#text128').text = response[9].max_supply;
$w('#text127').text = response[9].symbol;
});
});
});

For clarity, here’s how the code looks in the Home Page Editor.

Query CryptoCompare and Coin Market Cap API with Wix Code

As you can see on line 9, for example, we get the symbol of the coin from CoinMarketCap API first, which is the response object returned by the getTopCoins() function. And then we pass this symbol to the resp object returned by CryptoCompare API, which is in the getImageFromCyptoCompare() function. And everything else remains the same as we’ve received the info and displayed in the text element earlier.

And the final output after updated design now looks like this:

Display data from Coin Market Cap and Crypto Compare API with Wix Code
Conclusion

Wix Code has great potential that I believe could help the platform continue to grow. The addition of Wix Code to the Wix suite will eventually make it possible to develop a fully functioning app with custom components that will not need a special backend. One of the most significant features of Wix is that it is serverless and Wix code will only continue to expose these benefits. A combination of all the ready-made features and component of Wix plus Wix Code opens up new ways to think about your application, giving you a powerful toolset for creating awesome websites quickly.

What is in a block? - Blockchain

In my previous article, I tried to described the concept of a blockchain with code. This time, I'll try to describe the structure of a single block. I will use the Bitcoin blockchain to explain blocks, but keep in mind that the concepts will remain more or less the same. It could be useful to read my&nbsp;<a href="https://dev.to/damcosset/trying-to-understand-blockchain-by-making-one-ce4" target="_blank">last article</a>to understand a few things first.

Introduction

In my previous article, I tried to described the concept of a blockchain with code. This time, I'll try to describe the structure of a single block. I will use the Bitcoin blockchain to explain blocks, but keep in mind that the concepts will remain more or less the same. It could be useful to read my last articleto understand a few things first.

Structure of a block

A block is a container data structure. In the Bitcoin world, a block contains more than 500 transactions on average. The average size of a block seems to be 1MB (source). In Bitcoin Cash ( a hard fork from the Bitcoin blockchain ), the size of a block can go up to 8MB. This enables more transactions to be processed per second.

Anyway, a block is composed of a header and a long list of transactions. Let's start with the header.

Block Header

The header contains metadata about a block. There are three different sets of metadata:

  • The previous block hash. Remember that in a blockchain, every block is inherits from the previous block because we use the previous block's hash to create the new block's hash. For every block N, we feed it the hash of the block N-1.
  • Mining competition. For a block to be part of the blockchain, it needs to be given a valid hash. This contains the timestamp, the nonce and the difficulty. Mining is another crucial part of the blockchain technology, but it is outside the scope of this article.
  • The third part is a merkle tree root. This is a data structure to summarize the transactions in the block. And we will leave it at that for now. More on this later.
Block identifiers

To identify a block, you have a cryptographic hash, a digital signature if you will. This is created by hashing the block header twice with the SHA256 algorithm. For example, this is a block. I will refer to this block as an example for this article.

The block header hash for this particular block is (right column): 000000000000000000301fcfeb141088a93b77dc0d52571a1185b425256ae2fb

We also can see the previous block's hash (right column): 0000000000000000004b1ef0105dc1275b3adfd067aed63a43324929bed64fd7

Remember that we used the second hash to create the first. Every block uses the previous block's hash to construct its own hash. The block hash is a unique identifier. You won't find two blocks with the same hash.

The other way to identify a specific block is the block height. The is the position of the block in the blockchain. Our example's block is in the 500312 position. This means that there are 500311 blocks before this one. Since the creation of the Bitcoin blockchain in 2009, 500312 blocks have been created ( at the time of writing obviously ).

A block height is not unique. Several blocks can compete for the same position in the case of a fork, like Bitcoin Cash for example.

Merkle Trees

The transactions in a block are contained in a structure called a merkle tree or binary hash tree.

I feel that topics like that are easier to understand with actual examples. So we'll go coding for this. A merkle tree is constructed by recursively hashing pairs of nodes ( in this case, transactions ), until there is only one hash, called the root or merkle root. If we stay in the Bitcoin world, the cryptographic hash algorithm used is SHA256. This is applied twice each time.

An example: We have a block with 4 transactions. For the sake of simplicity, each transaction is a string:

const tA = 'Hello'
const tB = 'How are you?'
const tC = 'This is Thursday'
const tD = 'Happy new Year'

To construct our merkle tree, we start from the bottom. We take each transaction and double-hash them. I'll use the js-sha256 package here.

const sha256 = require('js-sha256').sha256

// Double-hashing here
const hA = sha256(sha256(tA))
const hB = sha256(sha256(tB))
const hC = sha256(sha256(tC))
const hD = sha256(sha256(tD))

//Results
52c87cd40ccfbd7873af4180fced6d38803d4c3684ed60f6513e8d16077e5b8e //hA
426436adcaca92d2f41d221e0dd48d1518b524c56e4e93fd324d10cb4ff8bfb9 //hB
6eeb307fb7fbc0b0fdb8bcfdcd2d455e4f6f347ff8007ed47475481a462e1aeb //hC
fd0df328a806a6517e2eafeaacea72964f689d29560185294b4e99ca16c63f8f //hD

Ok, great. Now remember that I wrote a merkle tree is constructed hashing pairs of nodes. So, we will pair our transactions and concatenate their hashes. Then, we will double hash them too. We will create a hash using the hashes hA and hB, and another for hC and hD. Then, we repeat that process until we have only one hash left and no more pairs to work with. The last hash will be our merkle root.

With only four transactions, this will be rather quick:

//Pairing hA and hB

const hAB = sha256(sha256(hA + hB))
//5dc23d1a2151665e2ac258340aa9a11ed227a4cc235e142a3e1738333575590b

//Pairing hC and hD

const hCD = sha256(sha256(hC + hD))
//ff220daefda29821435691a9aa07dd2c47ca1d2574b8b77344aa783142bae330

// We do it again. We pair hAB and hCD
// This is our root!
const hABCD = sha256(sha256(hAB + hCD))
//301faf21178234b04e1746ee43e126e7b2ecd2188e3fe6986356cc1dd7aa1377

The node at the top of the merkle tree is called the root. This is the information that is stored in the block header in each block on the blockchain. This is how transactions are summarized in each block. In our example block given earlier, the merkle root can be found in the right column: 

a89769d0487a29c73057e14d89afafa0c01e02782cba6c89b7018e5129d475cc

It doesn't matter how many transactions are contained in a block, they always will be summarized by a 32 bytes hash.

Note: The merkle tree is a binary tree. If there is an odd number of transactions, the last one will be duplicated so we can construct our tree.

Because all the leaves in our tree depends on other leaves, it is impossible to alter one leaf without altering others. If you change only one leaf ( one transaction ), the hash changes, therefore the hash you constructed by pairing it with another leaf changes, therefore the merkle root will be different.

You can prove that any transaction is included in a block by creating a authentification path or merkle path. You only need to know log base 2(N) 32-byte hashes. For example:

-For my 4 transactions merkle tree:

log base 2( 4 ) = 2 => If I have a path of 2 hashes for a tree of 4 transactions, I can manage to prove if a transaction belongs to this merkle tree.

For a 16 transactions merkle tree:

log base 2( 16 ) = 4 => If I have a path of 4 hashes for a tree of 16 transactions, I can manage to prove if a transaction belongs to this merkle tree.

log base 2( 1500 ) = 10.55 => If I have a path of 11 hashes for a tree of 1500 transactions, I can manage to prove if a transaction belongs to this merkle tree.

Perhaps a little diagram will help.

There are 16 leaves in this tree. We construct our tree from the bottom up by pairing each leaf. Now, anybody can prove that the leaf I ( in orange ) is part of this block by having the path given in green. We have only 4 hashes, but that is enough to know if the leaf I belongs here. That is because with those informations, we are able to construct every single leaf we need( in yellow ). We can create IJIJKLIJKLMNOP and the root and check if those hashes correspond. This is why it is very complicated to cheat a blockchain. To change one thing means you must change everything.

Well, that's pretty much what a block contains in the Bitcoin blockchain. Hope it helped!

The worldwide Blockchain market is right now worth an expected $1.2 billion and specialists foresee that it will arrive at a $57 billion valuation by 2025, developing at over 69% every year.

Significant enterprises and investors are teaming up with Blockchain counseling organizations to grow new digital currency innovation, savvy contracts, conveyed records for customary banks, gaming tokens, and inventory network the executives frameworks.

What Is Blockchain?

Customary financial uses a bank as the record and mediator. To move cash to a companion, an individual should initially contact their own bank and request that they move cash to a particular record number. The bank checks the sender’s record for assets, moves those assets to the goal, and records the exchange on the sender’s record. The accepting bank must accomplish something very similar.

In any case, the issue with this customary financial framework is that records are put away inside and are defenseless against hacking and control.

Blockchain disposes of this hazard by putting away all records online in a decentralized, unknown record that can be gotten to by anybody. Blockchain uses squares, or accumulations of information, like spreadsheet lines and segments, to store information. Squares are added to the “chain” in successive request.

In contrast to conventional bank records, which are put away inside, each blockchain client has a total record of the whole blockchain on their PC. This implies they can rapidly discover any exchange that has ever happened in the event that they have the comparing hash code. Since that information is put away freely, it can never be changed or erased — giving clients genuine feelings of serenity and trust in the framework.

Organizations keen on exploiting the blockchain upset should scan for up-and-comers with skill in the accompanying programming languages.

Here are the best programming languages for Blockchain

1. C++

C++ keeps on being one of the most famous programming languages in the tech world and is a prevailing power in the blockchain business also. The article arranged language is ideal for blockchain improvement, since it utilizes similar standards, for example, epitome, deliberation, polymorphism, and information covering up, as blockchain to avoid incidental alters to information.

Engineers additionally prize C++ in view of its memory control abilities. The language helps keep squares secure and deal with an enormous number of asset demands by enabling each system hub to acknowledge or dismiss individual squares.

C++ is additionally utilized broadly by blockchain advancement administrations due to the manner in which it handles parallel undertakings and stringing. The language is equipped for taking care of both parallel and non-parallel assignments, notwithstanding improving single-string execution.

EOS is an awesome case of a blockchain program worked with C++. The open source programming was discharged by Square in 2018 and is intended to process exchanges more rapidly than choices by restricting the product to only 21 square creating hubs. This enables the product to affirm an exchange in under a second and settle it in only two minutes.

2. JavaScript

GitHub as of late positioned JavaScript as the most mainstream language for developers — with a fantastic 95% of sites utilizing it here and there. Be that as it may, JavaScript isn’t just the lord of web advancement; the adaptable programming language is additionally utilized broadly for blockchain improvement.

One reason why blockchain designers prize JavaScript is a direct result of the manner in which it handles offbeat code. This is significant in blockchain, as thousands or even a great many exchanges might be started simultaneously. Offbeat, parallel programming empowers a program to finish numerous activities all the while. Standard, synchronous programming just can’t deal with that volume.

By running numerous activities on the double, offbeat code can improve programming responsiveness and application execution. This empowers blockchain projects to deal with the enormous volume of activities without hindering execution and disappointing clients.

3. Java

The only language that can challenge the reign of C++ in the industry is Java, and for good reasons so. Java is in many ways similar to C++ regarding its object-oriented approach and a vast community of third-party applications and platforms. The main reason to use Java as the de-facto blockchain programming language in the industry is, however, its highly-capable portability.

Programs written in Java are portable across any computational device, as they don’t rely on system-specific architecture, instead uses the universal JVM(Java Virtual Machine) for execution. This makes Java one of the best programming languages for blockchain.

4. Python

Python is probably THE most trending programming language you can learn these days!

It's very popular because it's easy to learn and use, runs on all operating systems and allows you to build a broad variety of programs: Be that web applications, desktop applications, utility scripts or using it for data science and machine learning.

You'll do so whilst building your own Blockchain and Cryptocurrency. These are of course also highly trending topics and not a lot of people understand what a Blockchain really is, you'll learn a lot about the core concepts of the Blockchain and you'll see how Python can be used for the many aspects that make up a Blockchain and Cryptocurrency.
