The React Js landscape is always changing, and every little change matters. The whole idea behind React Js is to be able to create rich, engaging, and fast web apps with minimal efforts.

As a React JS developer, you have the mandate of setting up achievable goals. More importantly, helping businesses leverage technology in accelerating growth, cutting costs, and raising conversion rates.

While you’ve been able to achieve these goals with results, you can even scale higher. That’s if you can make these seven little changes to your React Js projects;

1. Treat React Js Like a View Library

It’s a view library and needs to be treated as such. Don’t approach React Js as if it’s an MVC Framework. It’s not, and you’ll have to look elsewhere for your M and C, as React Js is just a V in the tripartite.

The thing is, you’ll have a mess of code if you treat it as an MVC.

2. Focus on Writing Stateless Components

You’ll be causing yourself quite much pain if you write components with much state. Let’s break this further; components that are difficult to test, difficulty in sharing information to other parts of the app, and exerting too much mental energy into the process are few of the problems with states.

When dealing with states, things are pretty easy to get out of control in your effort to add just another item.

3. Never Forget to Use PropTypes

Your components deserve safety, and it’s only PropTypes that can guarantee this safety.

With PropTypes, you can catch bugs early, and it will even serve as documentation. One that prevents your users from having to search through the entire components for props needed. In the same vein, adopt dynamic typing rather than static typing in your components. Finally, allow your tests to fail on any proptype errors.

4. Employ Shallow Rendering

Right from the onset, testing React rendering has always being a grey area. Not because of how difficult it is, but due to its evolving nature.

While there are numerous approaches to rendering, there’s no one that can be regarded as the best. Nonetheless, you can always think of shallow rendering and prop assertion. This is because of how it allows you to render each component as a standalone. There’s no other method that provides for such isolation.

5. Make Good Use of The React and Redux Dev Tools

If you’ll make good of React Js, you’ll need all the help you can get. One of such help is making use of the React and Redux dev tools.

With the tools, you can easily render the tree of React elements. This will give you a clear view of how things will eventually look like in the browser. What you’ll find most useful is the ability to travel back in time. Choose to add it as a browser extension or as a dependency. What matters is the result you get out of it.

6. You Can’t Do Without Redux.Js

Remember, in point 1; we stated that React Js should be treated just as a view library. The question that should be on your mind should be, where do you now put all of your states and logic?

What we’ll recommend is Redux Js. Of course, we are well aware of Flux. We’ll still prefer to go with Redux Js for a number of reasons. First is the pure functions of the reducers; the small, simple, and better-documented API is another.

7. Keep Your Components Small

Ass obvious as this is, it’s worth mentioning. Let’s reiterate the fact that small components are understandable, test, and maintain.

These three characteristics will make your life easier as a React Js developer.

Final Thought

With the way Facebook and Instagram have made use of React Js, the possibilities are not limited. By making use of these tips, you can get more out of your React Js works.

How Your Apps and Services Can Achieve High Availability on Microsoft Azure

July 16, 2020 in Azure, how to, tools

The failure of critical components of computing infrastructure cannot be predicted. However, when running a mission-critical system, high availability is expected at all times. In clear terms, high availability denotes the functioning of computing infrastructure regardless of the status of components.

It is essential to state that to ensure high availability on any computing infrastructure, certain elements have to be in place. Firstly, the availability of redundant elements as a back up for critical components. From another perspective, a monitoring system should always be in place. This collects data to detects a failure in any running system. Most importantly is a failover switch that can analyze the data collected and swiftly switch over to the redundant components.

As an enterprise Microsoft Azure user, you should aim for a high level of availability. This is due to the variety of tools and mechanisms provided to help users achieve high availability. We’ve come up with checklists that can help you achieve high availability on Microsoft Azure;

  • Design a High Availability Architecture

To ensure high availability, you need to be able to predict the type of failures you are likely to encounter. Identify the implications of these failures while itemizing recovery strategies.

It’s technically referred to as a ‘Failure Mode Analysis,” and it is tasked with identifying the redundancy level of different components. In essence, the architecture should be designed to avoid a single point of failure while utilizing load balancing between redundant components.

However, put a mind to cost when designing the architecture as it’s likely to increases your costs. Most importantly, ensure that the systems are designed to fail gracefully without leading to any disruption in service.

  • Regular and Scheduled End-To-End Testing

Put your system under different failure scenarios and see how they respond. You can employ fault injection testing to carry out a combination of failure while also measuring the recovery time. The recovery time is a factor of how the redundant components are designed to take on the load shed.

Your end to end testing should take into consideration failover and failback. To get a clear view of how your system performs realistically, carry out loading. While this is ongoing, observe how the failure mechanism put in place responds.

Don’t also forget to carry out planned and unplanned disaster recovery exercises. During this time, see how your team carry out the disaster recovery plan.

  • Consistent Application Deployment

Having an automated application deployment will minimize the probability of errors and failures; this will create a faster recovery plan. The implementation of application code, when not planned, could result in failure.

Put in a release process that updates the system with minimal disruption of service. Aim for rolling out updates that will not lead to downtime of critical components. Plan to utilize a blue-green release to have your cloud environment available at the same time.

In all of these, institute a rollback plan that can quickly return systems to a working version. Always set the component up for restoration to the “last known good” version.

  • Prioritize Monitoring of Application Health

In time detection of issues is critical to ensuring high availability on Microsoft Azure. There are Azure health probes that provide current data about service availability. In carrying out these check functions, do it from outside of the application.

It would be best if you looked out for ill health in the metrics rather than the total failure of any component. When you pay attention to degrading metrics, you can arrest possible failure in time. Put in place an early warning system that tracks key indicators of application health and inform the team in time.

More importantly, put an eye on the allowed limits of your Azure subscriptions. Whenever you overload the limits, failure is imminent.

  • Employ Azure Availability Zones

There’s also the use of multiple availability zones to guarantee the high availability of Azure subscriptions. Being separate data centers, the availability zones runs on its cooling, power, and network.

Running services on multiple availability zone is encouraged as it guarantees resilience to failure, and prevent failure in the primary data centers.

Final Words

To be frank about cloud computing, anything that can fail, will. It’s just a matter of time. However, what is important is what happens and how you respond to the imminent failure.

Prepare your cloud computing environment for the expected failure by making use of this high availability checklist.

Augmented reality transforms your surroundings and builds fancier worlds on it. In other words, it greatly augments the way you experience the world around you with your senses. Apple AR kit is a stunning development platform that can help bridge between the user’s real world and the developer’s visual space.

The ultimate purpose of the AR kit for the developers is to create some games and apps that will create augmented reality experiences for the users on iPad and iPhone. Working on Visual-Inertial Odometry (VIO) technique, an AR Kit can help place a virtual object in a real room and create amazing new experiences. Here are the startling advantages of AR Kit.

Apple AR Kit Highlights

  • Rules out the need for the iOS users to install third-party apps for scanning QR codes as the pre-installed camera app of the iOS 11 does this job.
  • The two inputs that the VIO blends are the CoreMotion data and the camera sensor data. This helps in quick, stable and accurate motion tracking and let the objects appear as they are placed in real space.
  • The advanced camera sensor on the AR Kit precisely estimates the light intensity in a given scene and applies the proportionate lighting to the virtual objects. This can help create a highly realistic AR content to the users. This will facilitate more CPU for graphics rendering ensuring a higher visual fidelity.
  • The highly useful features of AR kit are the SceneKit and Metal support and third-party tools like Unity and Unreal Engine. Hence you will get great levels of detail and amazing visual fidelity.
  • The processors running the AR Kit are Apple A9 and A10 which are marked by the great performance and ability to create a highly descriptive visual content.
  • Apple Kit’s promises to the developers are endless and the developmental platform foretells the possibility to develop a lot of exciting games in future.
