Configure the development environment for learning HTML, CSS, PHP in Windows.

(article is published on linkedin.com (Alexander Panov) )

Beginning programmers always ask the question, where to start learning about creating websites? Search on the Internet gives a lot of various information, but unfortunately only more confuses novice developers. Having more than 5 years of teaching experience, I have seen many times how students, making breaks in computer games and deciding to become web developers, tried to customize development environments. They began to sort out the programs for layout. They grabbed Sublime Text, Notepad ++, Visual Studio Code, NetBeans or PHPStorm. We tried to install on our local computer WAMP (stands for Windows, Apache, MySQL and PHP) platforms, such as Denver, Xampp, Open Server and many others. But since there is no systematic knowledge in the head of a novice developer, there is no experience of customization, it was rare for some of them to set up a convenient development environment, and whoever got it, understood that it became more difficult to play, since many additional programs, smoothness in the game.

This article was born because of explaining for many years to each student how to do everything correctly and conveniently.

Once again I want to say that we will set up a working environment in the Windows system to study the creation of sites in HTML, CSS and their links to PHP. We will call this computer working, so that beginning web developers get used to the idea that their computer is their source of income.

I am Shalitha Suranga from Sri Lanka. I started Neutralinojs project with other two members as our research project at university.

Cross-platform application development is extremely useful among software development organizations because a large end-user audience can be targeted. Earlier there were several approaches, such as writing multiple codebases per each platform, writing a single codebase using conditionals for platform selection, or using a programming language which has a cross-platform virtual machine at run-time. There were drawbacks of each like complexity of design, limited low-level accessibility and slow learning rate. Cross-platform application development with web technologies came [1] after. Electron and NW.js are most popular frameworks which allow developers to make cross-platform applications using Javascript. Basically, these popular frameworks combine embedded chromium browser and node run-time [2], [3].

These frameworks are being used to create numerous cross-platform applications. Whereas the community pointed out several unseen drawbacks of these frameworks. Large bundled application size, high memory consumption and long development workflow are the key things which were criticized through internet forums and websites [4], [5], [6], [7], [8]. Table 1.1 shows the advantages and disadvantages of Electron/NW.js.

In this article, I decided to describe how the functionality of selecting and displaying photos on a specific place on the map was implemented in our photo service gfranq.com. The photo service does not work now.

Since we had a lot of photos in our service and sending requests to database every time the viewport changes was too resource-intensive, it was logical to divide the map into several areas that contain information about the retrieved data. For obvious reasons, these areas have rectangular shape (although hexagonal grid was considered too). As the areas become more spherical at large scales, elements of spherical geometry and tools for it were also considered.

In this article, the following issues were raised:

• Storing and retrieving photos from the database and caching them on the server (SQL, C#, ASP.NET).
• Downloading necessary photos on the client side and saving them to the client cache (JavaScript).
• Recalculation of photos that must be hidden or shown when the viewport changes.
• Elements of spherical geometry.

Introduction & Recap

In the previous blog post, we learned how to filter, sort and group our table. This is a fundamental aspect of every CRUD application because most of the time users have to deal with hundreds of hundreds of records.

What will be covered on this exercise

With Part 3 of this series of blog posts, we will learn how to create a Master-Detail application leveraging the SplitApp UI control and how correctly configure the app’s manifest to handle routes and targets.

• SplitApp: UI control that allows you to create a Master-Detail application (used as a replacement of the App control)
• Routing: we will configure the manifest.json to correctly handle the routing of the application
• ObjectHeader: control that enables the user to easily identify a specific object. The object header title is the key identifier of the object and additional text and icons can be used to further distinguish it from other objects
• Navigation to a detail view and bind the element context: you will learn how to navigate and open a detail page and bind the current View (of the detail) to a new context
• List: in the master page we will use a list to display BusinessPartner because we will have less space

I'm Ivan Kopenkov, a senior front-end developer at Mail.ru Cloud Solutions. In this article, I will tell you about the approaches we have used for the UI library components customization. You will also learn how to significantly decrease bundle size, cutting off all the unnecessary modules Ant Design takes there.

In our case, we are making wrappers for original Ant Design components inside the project, changing their appearance, and developing their logic. At the same time, we import both customized and original components right from the ant-design module. That saves tree shaking functionality and makes complex library components use our wrappers instead of original nested elements.

If you are already or about to use Ant Design, this article will provide you with a better and more effective way to do so. Even if you have chosen another UI library, you might be able to implement these ideas.

Introduction & Recap

In the previous blog post, we started designing our application rendering a table with some Business Partner. We learned what OData protocol is, how to read an OData XML manifest, how to bind data to a Table and how to customize columns layout based on different screen resolution.

What will be covered on this exercise

With Part 2 of this series of blog posts, we will learn how to interact with data in our Tables and List. We will learn how to filter and sort data in a smart way.

• Create JSONModel to handle local data
• Set a default sizeLimit to our JSONModel
• FilterBar: UI control that displays filters in a user-friendly manner to populate values for a query
• Use XML Fragments to create a View Settings Dialog to handle sort and group data
• Filter and Sort data
• Add an Info Toolbar to our table to display useful information

Introduction & Recap

In the previous blog post, we have created a new SAPUI5 application on our SAP SCP WebIDE Full stack and we have configured it to use the destination to the SAP Netweaver Gateway Demo ES5.

What will be covered on this exercise

• What is an XML Metadata Manifest and what’s inside it?
• How to use our OData Model and bind it into our application
• Use a sap.m.Table with items and property binding
• Use sap.ui.model.type.DateTime to format JavaScript Date
• How to style columns to act differently on mobile/tablet/desktop devices

Have you ever wondered how to track when elements with positions: sticky become fixed? Eric Bidelman has an amazing post on this topic, go and read it now.

I've found some difficulties while using it in my project. Here they are:

1. It breaks encapsulation. sticky-change event relates to header element, but you have to insert sentinels to header's parent (and make it position: relative).
2. It involves lots of factors that should be consistent and their connection is not always obvious. For example you can't set --default-padding greater than 40px, which is top-sentinel's height.
3. You can't track block in the middle of an article.

Let's try to improve it!

inb4: This is not another "setting up" a new project with Vue and TypeScript tutorial. Let's do some deep dive into more complex topics!

typescript is awesome. Vue is awesome. No doubt, that a lot of people try to bundle them together. But, due to different reasons, it is hard to really type your Vue app. Let's find out what are the problems and what can be done to solve them (or at least minimize the impact).
