Using a Redis object cache for WordPress is a great way to make your WordPress website faster, especially if you’ve already gone through the “Making WordPress Fly” series of tutorials (noted that one commenter there actually mentioned Redis). You’ll need an Ubuntu 14.04 VPS with WordPress already setup on it. You can get an Ubuntu VM here if you don’t have one. You don’t have to use the aforementioned HHVM setup for this tutorial. However, using both HHVM and Redis object caching will give you the fastest load times. I will be releasing another article in the near future about improving HHVM stability for production deployments by using a PHP-FPM failover and an upstart script which does automatic respawning after a crash, something HHVM does not do by default on Ubuntu. Back to Redis – Redis is possibly the best way at present to implement the WordPress object cache. For a long time I have been a proponent of either APC or Memcached in combination W3 Total Cache for the object cache in WP.
WHY USE A REDIS OBJECT CACHE FOR WORDPRESS?
During a recent server setup for a new website (My French City) I came across an issue. Caching using APC or Memcached helped with front end speed, but the admin area was painfully slow. This site was a multisite install with domain mapping and hundreds of plugins. There were simply too many queries going on in the backend for it to be snappy. After some searching I discovered that implementing Redis to back the WordPress object cache was a great way to improve backend speed. After implementation it turned out it did a better job on the frontend then W3TC and Memcached, which was a pleasant surprise. HHVM does a great job of speeding up PHP and MariaDB 10.1 is also fast. But on a heavy site like this with lots of plugins, database queries are still the issue. Redis is an elegant NoSQL datastore solution to this problem.
A Redis object cache can be implemented in just a few commands on Ubuntu 14.04. Assuming you already have a working WordPress install (LAMP, LEMP , etc.) the process of getting redis working with WordPress is easy. First connect you your instance via SSH. Once connected:
sudo apt–get update
sudo apt–get install redis–server php5–redis
Now Redis is installed. To configure a Redis object cache for WordPress there are a few small changes we need to make. Open up /etc/redis/redis.conf then add these two lines at the bottom:
Now you’ll need to make some changes to WordPress. You’ll need to grab this file. Written by Eric Mann this file will allow WordPress to use a Redis object cache for awesome speed improvements. Once you’ve downloaded that file, make sure you disable W3TC object and database cache if you are using either. Now that Redis is running (and PHP knows how to connect to it), it’s time to tell WordPress to use our Redis object cache. You need to open wp-config.php and let WordPress know what host and port Redis runs on, and add a salt to keys. Add these lines:
Then place the file in you downloaded above in webroot/wp-content/object-cache.php, where webroot is the directory your website files are located within. Once this is done make sure the redis-server is running using sudo service redis–server status . Now you WordPress site is using a Redis object cache. You should notice significant speed gains once you click through a few pages and the cache is populated with queries. If you want to view the Redis console to see what kind of data is being stored run this command: sudo redis–cli monitor . That will show you a verbose look at what is going on in your Redis cache.
Unfortunately I do not have a control before and after for the speed difference. However here is a Pingdom load test of a page on this website:
I will be writing more about this in the future. Please leave your thoughts or any contributions in the comments below. At that time I may include more detailed information on the performance gains achieved using Redis object cache with WordPress.
But, choosing one from both of them is a difficult thing.
React vs. Angular is a never-ending debate. However, this post will not help you to select the best one, neither other articles available on the internet, but will surely guide you with the complete knowledge that suits your project the best.
Let’s get started.
Brief Overview and History
Other than Facebook, leading tech brands like Amazon, Pinterest, Airbnb, Twitter, Udemy, Paypal, Reddit, Tumblr, Walmart and many more are using React for web development.
Moreover, it came a decade ago in 2010, then to pace up with the latest technologies, Angular keeps rolling up with new upgrades at regular intervals. The latest version Angular 11 has an enormous number of features and functionalities.
Performance: Which is Better?
React.js uses virtual DOM (Document Object Model) which enables to access and modify the document content, layout, and structure; it exists entirely in memory. This virtual DOM is light in weight; thus reduces the load on the browser.
React reuses the code components, which doubles the productivity and optimizes the code practice.
For instance, you just want to update the contact number in your profile, DOM updates the entire tree structure of HTML tables until it reaches the needed data, while virtual DOM updates only the contact number without updating the entire HTML. This results in faster performance – no matter the size of the app.
Angular works on real DOM which makes the app slower while dealing with tons of data requests. However, Angular uses elements like Shadow API to make the app work fast. A wide range of other tools and practices are available to build Angular apps faster, better, and to monitor performance.
Architecture and Structure
React.js is all about components; it builds UI by breaking them into components
React is made up of multiple components and each component has logic and controls.
Some of them include:
Their codes are readable and logically structured. React provides only view and model layer- controller is added as per the usage from other libraries.
Angular is a framework that provides a complete set up to start with the application. No need to look into libraries, routing solutions, and structure; simply start building.
Angular is based on three layers: model- view – controller. In Angular, the application is broken into different files enabling to reuse of the components in a different part of an application.
Bundle Size: Does size matter?
File size matters to run a large and complex application. Compared to Angular, the bundle size of React is small. The smaller the file, the faster it works. React uses webpack to split the code into smaller parts to reduce the bundle size.
Learning curve: Which is easy?
Developers may find it difficult to learn at the initial stage but since there are no logical structures to learn – no complexities, it is a favorable tech stack.
New updates are rolled out frequently and react even provides useful resources, making it easy for the newbies to develop an application without any hassle.
Angular is quite difficult to understand compared to react. Since it has a huge library, learning all the concepts is quite time-consuming.
It provides resources to solve complex issues but there are some syntax and components to learn which is quite unavoidable.
Unidirectional or two direction Data Binding?
React supports one-way data flow, which means the application’s data flows in a single direction, and only the model can change the app’s state.
The developers cannot alter the UI elements without updating the model state. One way data binding makes code more stable provides a better overview and also makes debugging of an app much easier.
Angular supports bidirectional data-binding which means sharing the data with a component class and its template. If you change the data in one place, it will affect elsewhere.
This two-way approach provides a well-organized coding structure, making the framework more flexible and developers can hassle-free work with.’
Market Share and Trends
Both frameworks are highly popular; both of them are highly used by the developers but the demand for React is increasing every year.
Let’s see how:
According to Statista’s, world-wide developer survey, React.js is used by 35.9% of developers and Angular is used by 25.1% of developers.
React has 160k stars on GitHub, and Angular has 59.5k stars on GitHub.
The npm trends shows more downloads for React than Angular. Google Trends also reports more searches for React across the world.
As per JetBrain’s developer ecosystem 2020 report, React is the most popular front-end development framework.
Community and Support
As React is developed by Facebook and Angular is maintained by Google, both of these frameworks has huge community support. Both frameworks provide updates and releases frequently. Software developers and designers collaborate and contribute frequently to increase the credibility and reliability of the framework.
We have pointed out the majority of the comparison needed to select between react and Angular. With this comparison, you might have got a clear scenario of React and Angular.
Let’s quickly have a look at their advantages.
Advantages of Angular
Can be customized easily
MVC pattern simplified
No pre-requisite knowledge is required
Unit Testing ready
Advantages of React

When to use React?
If you have a complex and huge app to develop
If you’re developing computational apps, dynamic apps, single-page apps, native mobile apps
When to use Angular?
If you know Typescript, Java, and a previous version of Angular
If you’re ready to spend more time learning syntax and components
If you’re planning to develop low to medium level complex apps
If you need a large scale, feature-rich application
If you’re planning to develop enterprise software, hybrid apps, or progressive web apps
What’s your take? Angular or React?
Both frameworks have a great support community and are regularly updated with better features and functionalities to provide the best user experience.
Ultimately, choosing Angular vs React depends on your personal preference, size of your project, requirements, team size, budget, etc.
