Dexis-js – Holistic Guide

,

Dexie.js is a minimalistic indexed DB wrapper that provides near-native performance and easy to use database.  Hard to believe the dexie DB package size is around 22KB and it works cross-browser and devices. It solves the error handling by promises rather than events. So it will result in less of coding which turns out to be maintainable code.

Let’s start the how-to-use dexie database by creating an order electron app. Clone the electron typescript template and install dexie to it.

Exploring Kubernetes With Gigi Sayfan

,

You have probably read about Kubernetes, and maybe even dipped your toes in and used it in a side project or even at work. But understanding what Kubernetes is all about, how to use it effectively, and what the best practices are requires much more effort. Kubernetes is a big open-source project and ecosystem with a lot of code and a lot of functionality. Kubernetes came out of Google, but joined the Cloud Native Computing Foundation (CNCF) and became the clear leader in the space of container-based applications.

Let’s hear from Gigi Sayfan, author of the bestseller Mastering Kubernetes, Third Edition, about his methodologies and the approach he followed to create a powerful resource to acquaint learners all over the globe with the fundamentals and more advanced concepts of Kubernetes.

Big / Bug Data: Analyzing the Apache Flink Source Code

,

Applications used in the field of Big Data process huge amounts of information, and this often happens in real time. Naturally, such applications must be highly reliable so that no error in the code can interfere with data processing. To achieve high reliability, one needs to keep a wary eye on the code quality of projects developed for this area. The PVS-Studio static analyzer is one of the solutions to this problem. Today, the Apache Flink project developed by the Apache Software Foundation, one of the leaders in the Big Data software market, was chosen as a test subject for the analyzer.

So, what is Apache Flink? It is an open-source framework for distributed processing of large amounts of data. It was developed as an alternative to Hadoop MapReduce in 2010 at the Technical University of Berlin. The framework is based on the distributed execution engine for batch and streaming data processing applications. This engine is written in Java and Scala. Today, Apache Flink can be used in projects written using Java, Scala, Python, and even SQL.

Display the Latest News on Your Site With Mediastack

,

What an extraordinary year 2020 has been for the news! From the ongoing coronavirus crisis, to a turbulent US election, to the unrelenting march of Bitcoin, this year like no other we’ve been glued to our phones micro-analyzing every tidbit of news.

Which makes this the perfect time for mediastack, an awesome REST API that allows you to embed a customizable news feed, sourced from the world’s top news agencies, and updated by the minute, right on your site.

Integrating Global News with Your Site

News is the beating pulse of so many global industries. From political decisions that affect stock prices, to natural disasters that interrupt goods and services, to the whims of celebrities who overnight transform brands from unknown to must-have.

Whether you’re building a site for a non-profit in Louisiana that cares deeply about both Washington politics, and hurricanes in the Caribbean; or you’re building an app for a golf course in Halkidiki that’s focused on both local news, and golf around the world; delivering real-time news content to those users elevates UX.

Tightly integrating the news with your site makes it a hub for users hungry for that very news. The only limit is your creativity.

Display Up-to-Date News on Your Site

When news breaks around the world the top networks scramble to catch up; they simply can’t maintain correspondents in every town and city in the world, and so they rely on affiliates. mediastack pulls in news from over 7,500 different sources in over 50 countries worldwide, giving you access to exactly the same affiliates frequently used by big news organizations like CNN, MSNBC, BBC, or ABC.

When it’s one of the big players in news that breaks a story first, mediastack still has you covered because as will as covering smaller, lesser-known sources mediastack delivers real-time news from CBS, Sky News, The Guardian, Al Jazeera, USA Today, and a host of trusted names across the industry.

If your site targets users that are only interested in certain types of story — like sports, or Hollywood celebrities — then you can even pull in stories from ESPN, TMZ, or Fox News.

Get Started Quickly with mediastack

Getting started with mediastack couldn’t be simpler, and there’s a free plan that’s more than enough to prototype your project.

Full documentation is provided with code examples for PHP, Python, jQuery, Go, and Ruby. To start integrating all you need to do is register for a free access key.

Once you have your free access key, you connect to the API, then customize the results you receive with simple parameters. You can specify the types of news, the precise sources (including omitting sources), languages, countries, and most importantly your keywords.

For example here’s how you’d request science news from CNN, but not TMZ:

https://api.mediastack.com/v1/news
?access_key=[ INSERT YOUR ACCESS KEY HERE ]
&categories=science
&sources=cnn,-tmz

Let’s say you want to display Spanish language crypto news on your site, it couldn’t be easier:

https://api.mediastack.com/v1/news
?access_key=[ INSERT YOUR ACCESS KEY HERE ]
&categories=business,technology
&languages=es
&search=crypto,bitcoin,btc,xrp,ripple,etherium,altcoin

The API sends back simple JSON data that’s easy to run through. Each news item includes the author, title, description, url, source, image, category, language, country, and a published_at timestamp that records when the story was posted.

Once the feed is setup, sit back and relax. It’s all automated from now on.

The Best Source of News for Your Website

mediastack is delivered by apilayer, quite rightly one of the most trusted names in APIs, and is capable of handling millions of requests simultaneously.

Fast, updated by the minute, highly customizable, reliable, and sourced from the biggest names in the news industry, mediastack is an amazing API.

There’s a free-forever plan that allows you to use the API without charge, for up to 500 API calls per month, that’s perfect for trying it out.

For commercial use, plans start at just $19.99/month, and can handle up to 250,000 calls per month. Commercial plans also include HTTPS encryption, live news delivery, access to historical data, and — should you ever need it — technical support.

Head over to mediastack today, to prepare your site for whatever events 2021 throws at us.

Exciting New Tools for Designers, December 2020

,

Jumpstart your next design project or speed up a workflow with some of these new tools and resources. With so many new tools being developed all the time, you are almost certain to find something that can help you with projects.

Here’s what new for designers this month.

Everypixel Patterns

Everypixel Patterns solves a common design problem: Creating seamless patterns with graphic editors is such a long and exhausting process. That’s why some people choose to get patterns from stock websites but that can be a challenge too (and difficult to search). This tool makes getting patterns less time-consuming. It includes a gallery of well-designed content, which you can customize and edit as needed.

Multiavatar

Multiavatar is a free and open-source multicultural avatar maker. Type something in the input field and generate one of 12 billion avatars. (Everything is randomly generated and free to use.)

Lobe is a machine learning app from Microsoft that helps you create and train models. Start by showing the app examples of what you want it to learn and it will train a model for you. The tool is pretty easy to understand and you don’t need or experience or code knowledge to use it and you can train an app for free on your computer.

Laser Cat

Laser Cat is a silly and fun Google Chrome extension that adds a cartoon cat to your browser that allows you to zap away anything you want to remove in the browser window. It’s light and fun. Go play!

Pattern Collect

Pattern Collect is a curated gallery of patterns by various designs and illustrators. You can download patterns for use in projects or submit your own to share with the design community. The library is searchable and you can get new patterns via email if you subscribe.

FarbVelo

FarbVelo is a color palette generator that shows a new and random scheme with every refresh. The color choices are fresh and could work for a variety of projects, too.

Veed

Veed lets you host, edit, and deliver videos in the cloud using a REST API. It works on any browser, device, and bandwidth, and keeps your website light, even when delivering heavy video content.

Overlay

Overlay is a plugin for Figma or Sketch that transforms components and symbols into clean and reusable React, Vue, or HTML code. The benefit? Use it to create more consistent websites and design systems more quickly and in a pixel-perfect manner.

List.js

List.js is a library for adding search, sort, filters, and flexibility to tables, lists, and other HTML elements. It is built so that it will work on existing HTML and be invisible. Plus, it is simple to install and use.

What Are Design Tokens?

Design tokens are a “hot term” says Andy Bell. So, he wrote an explainer that breaks down what they are and how they might look in a standard data format like JSON. Read the explainer and you’ll be able to identify design tokens and understand them.

SVG Path Editor

SVG Path Editor makes it easy to manipulate paths for any SVG element. The grid – if you choose to use it – helps edits stay symmetrical and easy to manage.

Operator Lookup

Operator Lookup is a practical and fun tool. Enter a JavaScript operator in the search box to learn more about what it does. (You can also choose from a “keyboard” of options.) Thanks for the tutorial, Josh W. Comeau.

Beacon

Beacon is a tool designed to help you write, run, and share SQL in Slack. It makes collaboration easy so you can work on and run queries, debug, and resolve issues all in a single platform.

Plaiceholder

Plaiceholder transforms your images into lightweight placeholders using pure CSS or SVG.

2 Smartest Ways to Structure Sass

,

Sass – the extended arm of CSS; the power factor that brings elegance to your code.

With Sass, it is all about variables, nesting, mixins, functions, partials, imports, inheritance, and control directives. Sass makes your code more maintainable and reusable.

And now, I will show you how to make your code more structured and organized.

The organization of files and folders is crucial when projects expand. Modularizing the directory is necessary as the file structure increases significantly. This means structuring is in order. Here is a way to do it.

  • Divide the stylesheets into separate files by using Partials
  • Import the partials into the master stylesheet – which is typically the main.sass file.
  • Create a layout folder for the layout specific files

Types of Sass Structures

There are a few different structures you can use. I prefer using two structures — a simple one and a more complex one. Let’s have a look.

Simple Structure

The simple structure is convenient for a small project like a single web page. For that purpose, you need to create a very minimal structure. Here is an example:

  • _base.sass — contains all the resets, variables, mixins, and utility classes
  • _layout.sass — all the Sass code handling the layout, which is the container and grid systems
  • _components.sass — everything that is reusable – buttons, navbars, cards, and so on
  • _main.sass — the main partial should contain only the imports of the already mentioned files

Another example of the same simple structure is the following:

  • _core.sass — contains variables, resets, mixins, and other similar styles
  • _layout.sass — there are the styles for the header, footer, the grid system, etc
  • _components.sass — styles for every component necessary for that project, including buttons, modals, etc.
  • _app.sass — imports

This is the one I usually use for smaller projects. And when it comes to making a decision of what kind of structure to be used, the size of the project is often the deciding factor.

Why Use This Structure?

There are several advantages why you should use this organisational structure. First of all, the CSS files cache and in doing so, the need to download a new file for every new page visit is decreased. In this way, the HTTP requests decrease as well.

Secondly, this structure is much easier to maintain since there is only one file.

Thirdly, the CSS files can be compressed and thus decrease their size. For a better outcome, it is recommended to use Sass/Less and then do concatenation and minification of the files.

In case files become disorganized, you would need to expand the structure. In such a case, you can add a folder for the components and break it further into individual files. If the project broadens and there is a need for restructuring the whole Sass structure, consider the next, more complex pattern.

The 7-1 Patterned Structure

The name of this structure comes from 7 folders, 1 file. This structure is used by many, as it is considered to be a good basis for projects of larger sizes. All you need to do is organize the partials in 7 different folders, and one single file (app.sass) should sit at the root level handling the imports. Here is an example:

sass/
|
|- abstracts/
| |- _mixins // Sass Mixins Folder
| |- _variables.scss // Sass Variables
|
|- core/
| |- _reset.scss // Reset
| |- _typography.scss // Typography Rules
|
|- components/
| |- _buttons.scss // Buttons
| |- _carousel.scss // Carousel
| |- _slider.scss // Slider
|
|- layout/
| |- _navigation.scss // Navigation
| |- _header.scss // Header
| |- _footer.scss // Footer
| |- _sidebar.scss // Sidebar
| |- _grid.scss // Grid
|
|- pages/
| |- _home.scss // Home styles
| |- _about.scss // About styles
|
|- sections/ (or blocks/)
| |- _hero.scss // Hero section
| |- _cta.scss // CTA section
|
|- vendors/ (if needed)
| |- _bootstrap.scss // Bootstrap
|
- app.scss // Main Sass file

In the Abstract partial, there is a file with all the variables, mixins, and similar components.

The Core partial contains files like typography, resets, and boilerplate code, used across the whole website. Once you write this code, there is no further overwriting.

The Components partial contains styles for all components that are to be created for one website, including buttons, carousels, tabs, modals, and the like.

The Layout partial has all styles necessary for the layout of the site, i.e., header, footer.

The Pages partial contains the styles for every individual page. Almost every page needs to have specific styles that are to be used only for that particular page.

For every section to be reusable and the sass code to be easily accessible, there is the Section/Blocks partial. Also, it is important to have this partial so that you don’t need to search whether particular code is in the home.sass or about.sass files in the Pages partial.

It is a good idea to put each section in a separate .sass file. Thus, if you have two different hero sections, put the code in the same file to know that there you can find the code for the two sections. And if you follow this pattern, you will have the majority of files in this folder.

The Vendors partial is intended for bootstrap frameworks so, if you use one in your project, create this partial.

I recommend you use app.sass as the main folder. Here is how it should look:

// Abstract files
@import "abscracts/all"; // Vendor Files
@import "vendor/bootstrap.scss"; // Core files
@import "core/all"; // Components
@import "components/all"; // Layout
@import "layout/all"; // Sections
@import "sections/all"; // Pages
@import "pages/all";

Instead of having a lot of imports in the file, create an all.sass file in every folder. Each all.sass file should contain all the imports for that folder — and to make it more visible and understandable, create a main file.

Organisation

The biggest benefit of this structure is organisation.You always know where to check if you need to change something specific. For example, if you want to change the spacing on a Section/Block you go directly to the Sections/Blocks folder. That way, you don’t need to search in the folder to find the class in a file.

Facilitation

When the code is structured, the processes are promptly facilitated. They are streamlined and every segment of the code has their own place.

Final Words

Organizing code is essential for developers and together with all other skills, it is the most effective way to improve the functioning of the site. And even though there are multiple ways of organisation and different strategies, opting for simplicity helps you avoid the dangerous pitfalls. And finally, there is no right or wrong choice since everything depends on the developer’s work strategies.
