Developers are the focus of Hyvä Themes. Its user interface is straightforward and streamlined, making it simple and trouble-free to build themes.

Fewer dependencies are also involved, accelerating development and improving website performance.

Benefits of Hyvä Magento Themes for Developers:

SEO. A website’s lack of responsiveness is viewed as a “black mark.” When it comes to search engine optimization, Google will consider this. A website that adheres to SEO best practices is more likely to appear in Google search results. A website must load quickly, be clear to read and be simple to use in order to improve SEO. All of these criteria are met by Hyvä themes. Hyvä Themes are entirely responsive and compatible with a range of gadgets. Customers may quickly visit your site using a PC, tablet, or smartphone.

Flexibility. Almost any store owner wishes to make their online store stand out through unique design and features as well as give their customers a better user experience, so flexibility and customizability are crucial considerations when choosing a theme. Hyvä Themes offers great flexibility in terms of versatility and customization by utilizing contemporary frameworks.

Continual improvement. Regular updates add new features and functionalities to Hyvä Themes.

As for Disadvantages, They Look as Follows:

Pricing. When opposed to Luma-based themes, the license fee for the Hyvä theme seems to be relatively high at first glance. When the elements mentioned above are considered, this view relativizes rather quickly upon second glance. One often spends more when utilizing a Luma theme by itself to improve performance than the Hyvä theme’s buying price (while experiencing performance that is still subpar). Hyvä is related to prospective additional savings.

Trendy technologies. It would be best if you tracked out experts who are familiar with Hyvä technology. Although Magento 2 themes are well-known to developers, Hyvä has a few nagging issues that are constantly there in the background.

Incompatibility. Another flaw of Hyvä is its incapacity to support third-party extensions out of the box. However, Hyvä offers compatibility modules to address the issue. Elasticsuite, Sentry, and Google Tag Manager Extensions are a few examples of possible solutions.

The Hyvä idea is simply too compelling and robust, both technically and commercially. The guys behind Hyvä are not just any folks; they have been engaged in the Magento community for a long time. They contribute not only the required skills but also the motivation and conviction to guarantee that Hyvä + Magento will continue to be, over time, the ideal combination for carrying out e-commerce projects of all shapes and sizes.

Reasons to Implement Hyvä Magento Themes

It’s a great chance to redesign the page without spending too much money.

When using Hyvä, you must virtually start again when building your page’s Frontend layer. This indicates that you may implement a new design with a high probability that the optimization and redesign won’t be noticeably more expensive than extensive and thorough performance optimization. Our guiding principle is to go slowly and deliberately, but in this instance, doing both at once makes total sense.

2. The newly adopted Hyvä theme will be lighter, more contemporary, and simpler to maintain going forward.

The pattern indicates that Google will unquestionably raise the bar for expected page experiences. You have a much better starting point for optimization work using Hyvä. Going the Hyvä route will result in far higher overall outcomes than you could probably ever attain with your existing theme. The out-of-the-box theme will produce considerably better results.

3. Hyvä is the newer technology.

In general, it costs less to maintain newer technologies. Unbeknownst to you, the technology stack that powers the default Magento Luma theme was chosen roughly 10 years ago when Magento 2.0 development got underway. Luma’s optimization job is already getting more challenging and time-consuming. Some activities are more expensive to complete, while others are just not feasible. The issue will only become worse. With Hyvä, you may prepare for the future.

4. Hyvä’s creators and implementers are enthusiastic about the performance.

The network of engineers and businesses using Hyvä to enhance performance will continue to expand. On the other hand, the number of developers who are knowledgeable about and skilled in optimizing Luma may decrease.

5. Hyvä has a fantastic and vibrant community; new things always appear.

It’s possible that something that wasn’t offered last month has already been provided by one of the Hyvä Partners or Suppliers or adopted by Hyvä as a business. There is a good probability that contributions from the community will benefit you.

6. Components of buildings with Hyvä are frequently more comfortable for the engineer.

Working with Hyvä is a joy for developers. From a commercial standpoint, you should anticipate that if something happens, it will be simpler to find a replacement for your existing developer.

Key Takeaways For Hyvä Magento Theme

Hyvä Magento theme is a new yet popular solution that brings the functionality of your webstore to the next level. It effectively addresses the issues encountered with Luma, the default theme for Magento, and considerably eases the developers’ task.

The fundamental distinguishing feature of the Hyva Magento theme is an excellent website performance it provides. Another differentiator is the opportunity for upgrades that allows responding to fresh technology trends. The savings in time and costs for Hyva theme development are likewise meaningful factors in favor of this solution.

What is KnockoutJS and how is it relevant in Magento 2?

If you have just started to learn Magento or have already been doing for some time, there is a higher chance that you have not given a deeper thought about learning Knockout JS. But, it is vital to understand Knockout JS as its “data-binding” concept has been used pretty well in some crucial elements of Magento such as minicart and checkout.

So in this blog, we will be explaining about Knockout JS, and hopefully, when you reach the end of it, you’ll be making knockout apps in Magento. So sit back, relax, and let the journey begin.

Want to skip the basics and go directly to the main section? Click here

What is Knockout JS?

Knockout JS is a Javascript library which uses the MVVM pattern to bind data to certain DOM elements. Within Magento, we usually define a View-Model (which is a .js file) and a Template (which is a .html file), and the data in the template file is bound to the view-model, meaning whenever the data in the view-model changes, the template file changes too.

Why use data-binding?

Some of you might be asking “Well can’t we just use some library like jQuery to do the DOM parsing manually?“, And the answer is, of course, you can. You don’t even need jQuery. You can do all the DOM manipulations with core Javascript as well. But libraries like these are there to help us in writing standardized, maintainable, and beautiful code. Here’s a simple example, let’s say there’s a page where the number of visitors is being displayed on 3 separate sections of the page<div class="visitors"></div>  <div class="visitors"></div>  <div class="visitors"></div>

Now our Javascript would look something like this, which would fetch new visitor data every second<script type="text/javascript"> (function ($) { var visitors = 0; var fetchVisitorUrl = "..."; var fetchVisitors = function () { $.get(fetchVisitorUrl, function (data) { visitors = data.visitors; $('.visitors').html(visitors); setTimeout(fetchVisitors, 1000); }); }; fetchVisitors(); })(window.jQuery); </script>

See the $('.visitors').html(visitors);? That line is responsible for actually making the DOM manipulation. Without that, even when the new visitor data is fetched, it’ll not be visible on the page. Now suppose a new developer working on your project decided to implement a better way to fetch visitor data? Using sockets perhaps? Then he/she would also have to write $('.visitors').html(visitors);in his/her code. Hence the code becomes messy and redundant. Using data-binding, we change only the View-Model, and the View changes automatically.

Knockout JS and Magento 2

To make a knockout app in Magento 2, first we create a new module. Next in our template file, we write the following<?php /* @var Codilar\HelloWorld\Block\Hello $block */ ?> <div data-bind="scope: 'knockout-tutorial'">  </div> <script type="text/x-magento-init"> { "*": { "Magento_Ui/js/core/app": { "components": { "knockout-tutorial": { "component": "Codilar_HelloWorld/js/viewModel", "template" : "Codilar_HelloWorld/template" } } } } } </script>

This is basically initiating the Magento_Ui/js/core/appwidget with the components passed as options, using the text/x-magento-init tag. The data-bind="scope: 'knockout-tutorial'"says knockout to use the knockout-tutorialcomponent and template inside that DIV.

Next, we write our component file

app/code/Codilar/HelloWorld/view/frontend/web/js/viewModel.js

define([ 'uiComponent', 'ko' ], function(Component, ko) { return Component.extend({ clock: ko.observable(""), initialize: function () { this._super(); setInterval(this.reloadTime.bind(this), 1000); }, reloadTime: function () { /* Setting new time to our clock variable. DOM manipulation will happen automatically */ this.clock(Date()); }, getClock: function () { return this.clock; } }); });

The View-Models inside of a Magento 2 application, must return a Component.extendfunction call, where the Component is an object of the uiComponent, which were required here. Inside our Component.extend, we pass an object, which must contain an initialize function which will be the “constructor of our class”, so to speak.

And finally, we create our template file

app/code/Codilar/HelloWorld/view/frontend/web/template/template.html

<h1 data-bind="text: getClock()"></h1>

Now if we hit the url http://mywebsite.com/helloworld/ we should see a clock which should change every second, even though we didn’t explicitly do any DOM manipulations.

That’s all about how Magento 2 uses the knockout JS bindings. Do let us know in the comment section below about what you want my next Magento tutorial blog to be about. Also, don’t forget to check our previous tutorials!

Do You Know About JavaScript Why It So Important

JavaScript is a versatile language used for writing code on websites using functions and variables. By using JavaScript on your website, you can make your website faster and more user-friendly. It is great for creating website designs, user interfaces, and even small apps.

JavaScript is a popular language for web development and it’s used by millions of people all over the internet.

You must know that dynamic websites are websites that change as they are used, typically depending on the actions taken by users. JavaScript is used to write programs that carry out actions on web pages.

You can also use JavaScript to change the behavior of web pages based on user interactions or data collected by your site. In all cases, using JavaScript on your website will allow you to take advantage of its many features and make your site more flexible and responsive. JavaScript was designed by John Resig and released in 1995. What are the elements of the JavaScript Program? JavaScript program consists of a list of programming statements or instructions. These statements or instructions contains values, operators, expression, keywords like for loop, while loop, etc. Statements of JavaScript are grouped in the code block in curly brackets which is the form of function in JavaScript. What is JavaScript used for? JavaScript is majorly used for web-based applications and web browsers. Besides it, JavaScript is also used in software, servers, etc. Below are the following areas in which JavaScript is used –

To add dynamic behavior to web pages - There is an unlimited way to use JavaScript in web pages that allow user to interact with web pages e. g. - dropdown menu in the website nav bar, showing and hiding the block on button click, a slideshow of images, changing the color of the button or HTML element on mouse hover, audio, and video playing, showing animations, etc.

Each type has its own strengths and weaknesses which can impact how effective your code will be on different platforms. For example, mobile apps tend to require more coding time than front-end applications do; however, they can also be more versatile due to their ability to run in different browsers and devices without any problems.

By choosing the right framework for you, you can take your development experience to the next level. When choosing a JavaScript framework, it’s important to take into account your needs.

Todos los días nos vemos abrumados con nuevos frameworks, nuevas librerías y nuevas metodologías, la experticia a día de hoy es una ilusión basada en conocimientos sobre tecnologías pasadas y el aprovechamiento de la misma novedad; "en tierra de ciegos el tuerto es rey". Me refiero a pasadas por que son tecnologías de dos años atrás, podría enumerar entonces muchos de los conocimientos que el gremio exige y que entrega medallas escondidas en títulos que denotan dos situaciones: o explotación de una pasión nata en nosotros o una herramienta ejecutada de manera mediocre y sin poder usar el 100 por ciento de su potencial, comencemos con la lista:

Backend:Nos encontramos con lenguajes como:

Java

Python

Ruby

javascript(NodeJs)

Y de ahí se desprenden frameworks, librerías e IDEs que aunque cumplen la misma función, muchas solo tienen de diferencia que es lo mas usado de momento.Solo en java podemos encontrarnos con Spring Mvc, Spring boot, JFS, la lista es interminable.

No basta con esto, después nos encontramos con el frontend que a mi parecer debido a sus resultados inmediatos tiene mas influencia en nosotros y nos lleva a experimentar mas y adoptar de manera mas rápida las modas que transitan por este mundo del desarrollo, en este campo tenemos categorías por su función: están los frameworks o librerías que tienen como base el javascript y nos ayudan a operar acciones en el html permitiendo el dinamismo de nuestros desarrollos web por otro lado tenemos los preprocesadores de css como sass, less y mas, finalmente tenemos librerías que nos ayudan a la maquetación de nuestros sitios incluyendo funciones que son ya inherentes en las web.una lista bastante breve es:

JQuery(recontra Obsoleto)"pero me encanta, quizás es la nostalgia"

Knockoutjs(obsoleto)

Angularjs(obsoleto)

Angular 2 al 8

Reactjs

vuejs

embeberjs

backbonejs

less

sass

foundation

bootstrap

materialize

Cada vez que sale una nueva herramienta para la creación de software la experticia se ve comprometida por el tiempo de la misma en el mercado , y cada vez gracias a la nube tenemos mas recursos disponibles y es muy fácil escalar recursos para soportar nuestras descuidadas formas de programar consecuencias del desconocimiento en estas herramientas.Entonces las empresas buscan personas fullstack suponiendo que nuestros conocimientos y gustos deben estar al servicio de las tecnologías que estén en sus 15 minutos de fama.

Les dejo algunas referencias de las pocas herramientas que nombre y una pregunta que todos debemos hacernos: ¿cuanto tiempo trabajando en una herramienta nos hace expertos?.

mis favoritas: en backend c# en visual studio con .NetFramework o .NetCore y en front Angular 8; para móviles Xamarin Forms.

KnockoutJS – Hãy code theo cách của bạn

Giới lập trình front-end ngày nay đã khá quen thuộc với Angular JS và ReactJS. 2 framework do Google và Facebook phát triển và ngày càng trở nên phổ biến.

Tuy nhiên, hai nền tảng này cũng đang có sự cạnh tranh nhau rất quyết liệt khiến cho developer không biết nên lựa chọn nền tảng nào để phát triển ứng dụng cho mình.

Ngoài ra, AngularJS và Reacts đòi hỏi developer phải có kiến thức vững vàng về JavaScript như xử lý object, string, cũng như mô hình MVC để có thể tiếp cận và sử dụng thành thạo.

Bài viết này muốn giới thiệu một hướng đi khác, đơn giản hơn, dễ tiếp cận hơn trong lập trình front-end đó là Knockout

Knockout là gì?

Nói đến từ Knockout, chắc hẳn bạn sẽ nghĩ đến coding theo phong cách của một boxer, nhưng thực ra thì không phải thế.

Knockout JS là thư viên javascript giúp bạn tạo các ứng dụng linh hoạt và mượt mà (responsive display). Với Knockout, bạn có thể làm cho giao diện của ứng dụng được update tự động một cách đơn giản, dễ dàng khi có thay đổi data.

Vì sao nên sử dụng Knockout?

Knockout đem lại cho bạn rất nhiều sự tiện lợi

Knockout là một Pure Javascript library nên hoàn toàn tương thích với mọi trình duyệt

Dung lượng nhỏ, đơn giản nên không ảnh hưởng tới performance của trang web

Tài liệu hướng dẫn guideline khá đầy đủ, Knockout là một framework dễ học, dễ tiếp cận nhờ tính đơn giản của nó.

Tóm lại, Knockout là framework rất đáng để tìm hiểu.Kiến trúc và nguyên tắc hoạt động

Knockout được phát triển dựa trên mô hình Model-View-View Model (MVVM).

Trong mô hình này

Model: là phần chứa dữ liệu của ứng dụng và nó được tách riêng với phần giao diện người dùng (UI).

View: là phần giao diện người dùng như layout, GUI, những thứ hiển thị trên màn hình cho user sử dụng

View Model: là phần mô tả trạng thái của dữ liệu trên model, là trung gian giữa View và Model, quản lý phần dữ liệu mà người dùng đang tương tác. MVVM sử dụng cơ chế đặc biệt là Data Binding để cập nhật dữ liệu từ Model vào GUI component như TextBox, Button mà không cần sử dụng code-behind như thông thường.

Không phức tạp như Angular hay React, kiến trúc của Knockout rất đơn giản chỉ bao gồm 3 core feature

Observables là một Java objects của Knockout có tác dụng thông báo cho UI biết khi View Model thay đổi

Declarative Bindings: Hiểu đơn giản là Knockout gán value của một biến Javascript vào GUI ví dụ như textbox, button. Ví dụ:

Khi data personObj.hasStuff thay đổi value thì tự động được cấp nhật vào checkbox mà không cần code thêm xử lý change nào

Templating: Tập hợp DOM elements có thể dùng lại nhiều lần.

Nguyên tắc hoạt động của Knockout cũng rất đơn giản, dựa và cơ chế Data Binding của mô hình MVVM.

Có thể xem scenario sau để hiểu được cơ chế hoạt động của Knockout

User select Ticket từ dropdown menu

Một Event drop down change sẽ fire một binder

Binder tìm Action Logic tương ứng trong View Model và thực thi.

Action Logic truy cập vào Model Layer để lấy dữ liệu và cập nhật vào View Model (Dữ liệu ở đây là tên ticket class)

View Model thông báo cho binder biết sự thay đổi tên ticket class

Binder sẽ cập nhật vào GUI là text content nội dung lấy được từ bước 4

KnockoutJS case Study

Phần này ta sẽ bắt đầu với một case study đơn giản dùng KnockoutJS

Phát triển một trang web cho phép Fsofter lựa chọn phương án làm việc của mình.

Yêu cầu

User được lựa chọn phương án làm việc khi trở thành nhân viên Fsoft.

Không chịu OT, ON thì nghỉ (Fire)

Step 1. Cài đặt KnockoutJSThủ tục cài đặt Knockout không đơn giản mà là quá đơn giản.

Download KnokoutJS ở đây và include vào source code của bạn

Ngoài ra cũng cần cài đặt thêm JQuery

Step 2. Tạo giao diện

Giao diện sẽ bao gồm 1 dropdown box cho phép lựa chọn phương án làm việc. Value của dropdown box được lưu trong data model

<body>

<p> <select data-bind="options: working,

optionsCaption: 'Choose...',

optionsText: 'name',

value: chosenWorkStyle">

</select>

</p>

</body>

Chú ý đoạn xử lý data-bind trong code trên, đây chính là xử lý databinding của Knockout. Cho phép cập nhật data vào GUI

Step 3, Tạo Model

Tạo ra một Data Model để chứa dữ liệu, trường working chứa dữ liệu để bind vào dropdown box, trường name dùng để bind vào label

Data Model ở đây thực chất là một JavaScript object

function WorkingModel() {

this.working = [

{ name: "OT"},

{ name: "ON" },

{ name: "Fire" }

];

this.chosenWorkStyle = ko.observable();

}

Chú ý xử lý ko.observable(). Đây là xử lý giúp Knockout biết được khi nào thì View Model thay đổi.

Step 4, Apply Data Binding

Gọi api applyBindings để để thực hiện

$(document).ready(function () {

ko.applyBindings(new WorkingModel());

});

Chú ý xử lý này chỉ hoạt động khi toàn bộ trang web được load xong.

Bây giờ run ứng dụng, mỗi khi bạn thay đổi value trong dropdown box, thì trường text tự động cập nhật, mà không cần phải code thêm xử lý event change như thông thường.

Lời kết

Có thể nói KnockoutJs là một framework tuy nhỏ mà lại có võ. Với KnockoutJS, developer có thể thực hiện các kỹ thuật cao cấp hơn như binding dữ liệu, cập nhật dữ liệu dựa vào thao tác người dùng, từ trường này tự động sang các trường liên quan, KO (Key Observing – quan sát sự thay đổi theo key).

Hãy sử dụng Knockout, và code theo cách của 1 boxer.
