In the vast world of building mobile apps, React Native is a superhero toolkit that has been chosen by over 42% of developers and many a 

But here's the thing: as apps become more sophisticated, figuring out how they remember tasks (a.k.a. state management) becomes increasingly important. That is when Redux, Mobx, and the Context API come to the rescue.

Consider Redux to be the Scrum Master with a plan that keeps things predictable and flowing smoothly in large apps. Mobx? More of a laid-back hero, all about simplicity and going with the flow. Then there is the Context API, a built-in React sidekick that keeps things simple for smaller projects.

Which of the three should you choose? It is similar to selecting the best champion for your mission based on the size of your project and the personality of your team. Stay tuned as we explore the capabilities and quirks of Redux, Mobx, and the Context API to help you decide who your app's superhero should be!


Understanding React Native State Management

React Native: The Lego Block Approach to App Development

Consider building a house out of Lego blocks; you have these cool pieces (components) that snap together to create something amazing. That is, in essence, how React Native works! It is similar to having these app building blocks. Instead of starting from scratch, you can use these pre-made pieces (components) to put your app together.

Everything in React Native is a component—buttons, text boxes, images, you name it. Each of these components functions as a mini Lego block that can be reused and customized. As a result, rather than writing a ton of code for every little thing, you can mix and match these components to create your app. It is like building apps with Legos!

Let us now discuss "state." Consider the state to be your app's memory—it remembers things. For example, if your app has a counter that increases when you click a button, the number is saved in the state. It is almost as if your app's brain keeps track of things.

Now comes the tricky part. When your app grows into a massive Lego castle with tons of moving parts, managing memory (state) can become difficult. Imagine you have a thousand Lego pieces and you need to know which ones are where—it can be difficult to keep track of them all! Keeping track of all this information and ensuring that everything updates correctly can be difficult in large apps. That is where superhero strategies like Redux, Mobx, or the Context API come in handy to keep our app's brain in check and running smoothly, even when things get massive!

In a nutshell, React Native is like building your app with Legos; state is your app's memory, and as your app grows, it is like managing a giant Lego castle—exciting, but it requires some extra magic to keep everything organized!

Consider Redux to be a wise master who assists your app in keeping track of things. It is similar to having a box where all of the important information is kept. This is done in accordance with three important rules: actions, reducers, and the store.

: These are like sticky notes that inform the master about what is going on in your app. When you click a button, you are performing an action! Efficient managers are always interested in what is going on.

: These are the people who take action and decide what should happen next. When you press a number-increasing button, the reducer says, "Okay, let us add one!"

: This is the safe place where everything is kept. The store contains all of your app's vital information. At any time, the master can open the box and view the current state of your app.

Unidirectional Data Flow: A One-Way Street

Data flow is a one-way street in Redux. The action begins the journey, passes through the reducer, and finally arrives at the store. It is a tidy process that makes it simple to see how things change in your app.

Pros and Cons: The Good and the Tricky Parts

: Redux is ideal for large, complex apps. It organizes everything and makes it simple for developers to understand what is going on. It is similar to having a clear map for your app-adventure.

: For small apps, Redux can feel like using a cannon to catch a butterfly at times. It requires some setup, and if your app is not too complex, it may feel like overkill.

: Let us say you have a large app with a lot of components and data. Redux functions similarly to a scrum master, assisting all components in cooperating and ensuring that all data is handled without chaos.

Implementation in React Native: Making Magic Happen

Let us now apply the magic to your React Native app!

Integrating Redux into a React Native Application: A Step-by-Step Guide

Create a file called actions.jsto define your actions.

Create a file called reducers.jsto define how your state changes.

In your App.js or a separate file, create the Redux store.

In your component (AppContainer.js), connect it to the Redux store.

Best Practices for Redux Code Structuring in React Native

Separate actions, reducers, and the store into their own folders.

To improve readability, keep related files together.

To avoid typos and ensure consistency, define action types as constants.

Apply middleware like redux-thunk for handling asynchronous actions.

You can successfully integrate Redux into your React Native application by following these steps and best practices, resulting in a structured and maintainable codebase for managing your app's state.

Meet Mobx, your laid-back state management colleague. Mobx has this fantastic philosophy of keeping things simple, similar to how an office should be where everyone can find what they need without feeling stressed.

The state in Mobx is analogous to a whiteboard in an office. When something in your app changes, Mobx automatically notes it on the whiteboard. Assume you are updating a project status; Mobx makes sure everyone is aware of it without you having to go around telling everyone.

Actions and Reactions: Office Tasks and Post-Its

Mobx actions are similar to tasks on a to-do list. When you complete a task, Mobx ensures that the state is updated. Reactions are similar to post-it notes in that they are triggered when the whiteboard (state) changes. So, if the budget changes, Mobx will notify the finance team to double-check the figures!

Consider Redux to be a well-organized office library. It is great for large projects, but even for small tasks (like checking out a book), you have to go through several steps. Mobx, on the other hand, is like having a direct line to the office organizer—it is quick, simple, and ideal for smaller projects.


Pros and Cons: Mobx - Your Reliable Office Assistant

Advantages: Mobx - Your Office Organizing Pro

: Mobx is like having an office assistant who understands your needs without the need for a manual.It is simple to use and does not overcomplicate things.

: Do you need to reorganize your office (change states)?Mobx is adaptable and will easily adapt to your needs. It is like having a flexible office that can quickly adapt to different tasks.

Limitations: Consider Mobx for the Right Job

: While Mobx is user-friendly, there may be a learning curve, especially if you are used to different ways of organizing your office (state).

 Mobx is ideal for small to medium-sized projects.In case your app is massive, you might prefer Redux's structured shelves.

: For those cozy, smaller projects where you need to keep things organized quickly and easily.

: If your app requires real-time updates with minimal overhead, Mobx is your go-to assistant.

In the end, Mobx is like your trusted office assistant, keeping things organized, reacting to changes, and simplifying work without adding unnecessary complications. Although it lacks Redux's large library-like structure, Mobx is the go-to organizing tool for the right project

Step-by-Step Guide to Integrating Mobx into a React Native Application:

Create a file named mobxStore.js to define your Mobx store.

Step 3: Connect Mobx Store to React Native Components

In your component (AppContainer.js), connect it to the Mobx store.

Best Practices for Organizing Mobx Stores and Connecting Components:

Create different stores for different parts of your app to separate concerns.

Use @observable to identify properties that should be monitored.

This ensures that Mobx tracks changes to these properties.

Use@action decorator to define methods that modify the state.

This ensures that any changes to the state are tracked by Mobx.

, a leading custom software development company offers impeccable and intuitive live streaming app development services as per your requirements. They have an extremely talented team of 

 who are proficient in delivering attractive and powerful applications within the given timeline.

Online streaming services play a vital role in today’s tech-driven world by allowing you to watch anytime, anything, on almost all the smart devices available in the market. According to 

, the size of the video streaming market is globally expected to reach $224 Billion by the year 2028.

There are a number of online streaming applications that have captured the market efficiently such as Netflix, Amazon Prime, Hulu, etc. If we talk about Netflix, it is a leading video streaming application with a list of more than 110 million paid subscribers in the United States of America only.

In this article, we will take a look at how to create a live streaming app along with looking at some important information about the growing mobile streaming industry before comparing apps for broadcasting and watching mobile video content.

A live-streaming app is an app that allows users to record and broadcast video simultaneously. Such apps have grown in numbers in recent years, thanks to high-speed internet and advanced camera technologies.

These apps have fueled influencer marketing, entertainment, business marketing, and the way people interact over the internet. The following are some of the live streaming apps that are highly popular amongst users:

Facebook Live is well known for its Live calling features. On the other hand, Twitch is a well-known platform for gamers to broadcast their gaming sessions. Additionally, Douyu is the Chinese alternative version of Twitch, which boasts a higher number of active users.

What are the Types of Streaming Applications?

There are a number of different live streaming apps floating around the various popular app stores. So if you plan to find out how to create a live streaming app, we suggest finding out what kinds of video streaming apps there are:

It is one of the most popular types of streaming media. This is when you watch videos in a real-time mode. It’s recorded and broadcasted simultaneously. You can build a live 

 that broadcasts how users play games(Twitch), how they talk about different things, or even how they simply answer questions online(Periscope, Instagram Live, Facebook Live). The most popular live streaming apps are Facebook Live, YouTube Live, Livestream, Periscope.

In this type of streaming media, the principle is the same that users can listen to music without downloading it. Everything is simple. Pandora, Spotify, Apple Music are the most popular music streaming services you can find today.

This one makes it possible for users to watch TV series and movies without downloading them on devices. However, a distinctive feature is that they can pause content, resume, and rewind it. As a rule, users have to pay for a subscription to have access to the content. Netflix, Hulu, and Amazon Prime Video are leaders in this area.

The final streaming type that allows users to watch TV online. But, when they switch to on-demand video streaming services, they lose their favorite TV shows, sports channels, series, and so on. That’s why companies create live streaming apps with TV broadcasting. Hulu, Youtube TV, Amazon Prime Video are video on demand platforms but they also have plans for TV live streaming.

What are the Considerable Factors While Creating a Streaming App?

There are 4 key factors that you must consider before creating an online streaming service: market niche, platforms, monetization strategy, and license. This will help you in defining the project goal, target audience, and the way how you will make money with your video streaming app. A license is required to ensure compliance with the law.

To create a successful application, you should choose a niche on the market. Apart from on-demand video streaming service, there are many other options. Will you provide users with live broadcasts of sports events or show them world-famous cartoons, it depends on your interest.

Here are the types of content that you can stream:

Events such as meetups, conferences, speeches

Although a top priority is to create a streaming service application, consider building your product for

, too. This will help you in attracting more customers while increasing their satisfaction.

It is suggested by the following: first, build a web solution and analyze user feedback that you can collect through reviews, comments, social networks, polls, surveys, etc. Then, if based on user reaction you see that many people really want to have a smartphone app, you will launch a mobile version, too.

Integrating the right monetization model is a critical issue to generate profit and not to disturb the user experience. While Netflix provides paid subscription, there are plenty of other monetization strategies that you can choose between.

 Display ads and charging companies for placing them inside your video streaming app.

 Some content is available for free but users have to pay in order to access exclusive videos.

 As multiple ads can disrupt the user experience, you can charge customers for blocking them.

 One of the most popular strategies in video streaming solutions. To access video content, users make payments on a weekly, monthly, or annual basis. You can offer a free trial as Netflix does, so that people can try your product first.

In order to distribute content, every organization should ensure law compliance. You should buy a license to meet the required standards and stream videos. You can acquire a license by:

Renting the desired content from a distributor who has the right to provide such licenses.

You can use both options to meet user demand. Additionally, think about purchasing exclusive rights for streaming certain TV shows, films, or series. No other website or application will be entitled to show them, which means that you will have more loyal customers.

There are enormous steps that you need to follow in order to create a powerful streaming services app of your own.

The first thing to do is to decide what content your app will stream to users. To give you a clue on profitable steaming niches, we have mentioned some key ideas below:

Entertainment. Netflix and HBO show us that entertainment streaming services are very profitable. The audience is big enough to accommodate a new streaming provider.

Fitness. Fitness is another prospective niche for VOD services. People would love to pay for a subscription to have access to fitness-related videos anytime. Besides, you can add different video categories, like yoga, dance training, or a healthy diet to enhance a wider audience.

Education. Nowadays, people are more likely to watch “How to” videos, rather than reading tutorials and instructions. Moreover, you can choose from many sub-niches, like magic tricks, cake making, or even origami to attract a specific audience.

STEP 2: Deciding the Availability of Content

As the content is the basis of your on-demand streaming service, you need to determine what your content will be.

 Would you use videos from other distributors?

 Or, would you want to create your video content

If you want to cooperate with video distributors, you need to get a license for public performance. There are two ways to deal with that:

Renting a movie from the authorized distributor with licenses

Both options are great, and the choice depends on the goals of your business. If you choose the first option you might contact one of two leading authorized distributors or movies and T.V. series in the USA:

Motion Picture Licensing Corporation (MPLC)

STEP 3: Choosing the Model of Monetization

For an on-demand video service you can opt between three methods of video monetization:

: It is the most straightforward pricing scheme which means the user pays for each video to watch. You can apply this model if you want to develop a platform to broadcast concerts, trade shows, conferences, or sports events, like boxing and MMA.

: You can charge other companies for running video advertisements on your platform. Still, this monetization strategy would only work if your platform will become famous among users.

: As you remember, Netflix uses this exact monetization strategy. Besides, the subscription model is used by a third of professional broadcasters. Subscribers are charged a monthly fee to receive access to a content library. You can use this monetization technique if you will regularly release new content on your platform.

STEP 4: Analyzing the Requirements of Your Streaming Service App

You will be needed to maintain a balance in the following performance characteristics for efficient working of your video:

Internet speed impacts the platform’s ability to stream on-demand videos. The minimum internet speed to stream standard definition movies is more than 2 Mb/s (megabits per second). But to broadcast HD, 3D or 4K, your Internet speed must be much higher. Let us check the Netflix example.

2. Computing Architecture and Cloud Hosting

For keeping video content we recommend using cloud hosting platforms since cloud hosting has the following advantages:

Cloud hosting platforms are flexible and increase the amount of space automatically.

Such platforms allow quick access to video content

Cloud hosting platforms are cheaper than hard drives

An on-demand video platform requires complex architecture. As your business develops, the complexity of your architecture will only increase. Subsequently, you need to think about your platform scaling from the very beginning. In this way, you can avoid complex data migrations.

Moreover, you can use cloud computing capabilities for many operations, including:

It was launched in the year 2016. You have the option here to find the Smart Cast platform with applications. But you cannot install applications on VIZIO Smart TVs.

What is the VIZIO Smart Cast Television Integration Specifications?

SmartCast Television offers users quick access to spotlighted streaming entertainment apps. With the help of the SmartCast app, or just a remote control you can find content. And also update the preferred apps via the VIZIO interface. Moreover, users can manage their Television by using gadgets such as 

 Alexa, Siri, Google Assistant, etc. Here, users can also select how they wish to connect using their VIZIO devices.

The Smart Cast Television home screen comes with a top navigation bar. Also the numerous rows of interaction. Such as the App bars, Discover Rows, Hero Carousel. Placement within these Rows and App Bar is overseen by the VIZIO BD and editorial sections. Navigation here offers entry to search, TV shows, movie catalogs, etc.

It proposes content associates the option to get user engagement via HD representation. The hero carousel includes five distinct images. And it also voluntarily works through various artwork. By spotlighting the top row, the consumer may guide via Carousel images using a remote control with the left & the right keys. Each Hero Carousel includes an actionable switch that will either open a full-screen app or launch a video recording, picture a content screen.

It also proposes content associates the chance to boost the content. Here, customers can guide via the row with the help of the remote control. It has single or multiple labels for this section. Moreover, content with additional Discover Rows is available by checking the previous Apps Row.

These bars offer users a choice of the most famous streaming offerings. The applications are shown in the exact order for all the users. However, they can alter the arrangement order. Choosing an application will establish the focused application on the VIZIO display in full screen.

Here, the Films catalog offers algorithmic suggestions for movies across genres. With Smart Cast Television Home, and the Hero Carousel on the top shows films are from a preferred content provider. And it also deep links instantly to the associated content. Various rows of listings are editorially tailored and promoted also.

Here, VIZIO’s TV series catalog shows the same format as Movies. And with the help of editorial and some advertising components.

Picking a film title from any unit in Smart Cast Television directs to the Content information page. And it contains crew, cast & a movie poster, etc. It also pictures various applications that offer the name, with the estimate and other resolution details. These areas are developed based on the addition of third-party content detail feeds. Moreover, it shows connections to videos, trailers along with recommendations for other related featured content.

With the help of Extras, consumers can add third-party integrations and check the Smart Cast platform info.

To integrate with VIZIO’s application platform, app associates must share a content feed. The metadata allows addition in TV shows, movies, Search, etc. The below-mentioned steps should be executed:

Offer a content metadata feed delivering full-textual attributes for discovery as well as search.

Give points for publishing content replay on TV displays and mobile devices. In the case of phone devices integration and Smart Cast TV, it demands deep linking integration specifications with HTML5 employing URLs.

Users can guide to Smart Cast Television by changing to the Smart Cast source utilizing the input key. Input source is also shown with physical information references for HDMI tuners & devices.

Further, customers can access Smart Cast Television utilizing the different remote control modes:

And, Smart Cast Mobile application with d-pad performance

The Smart Cast forum for 10-foot applications is backed by Chromium browser tech. All UI applications will operate within the Chromium browser only. Moreover, the designers will have the authority to do this remote debugging.

In the case of the Smart Cast Television medium, content associates develop applications for the 10-foot experience employing HTML5. The apps also run inside the Chromium environment. When projecting content from Smart Cast Mobile, VIZIO will then deep-link it to the HTML5 apps. Additionally, these applications must merge with VIZIO’s JS library to allow platform requirements and remote control, etc.

For content associated with a different Cast receiver published from their app, VIZIO keeps a mapping among the receiver and the HTML5 app. If the user pushes the back button while an Associate Cast Receiver is portrayed, the corresponding Associate HTML5 App will be launched.

VIZIO will observe the usage of Smart Cast Television as drafted in the privacy and information policies. And it also supplies reports to content associates as decided among the parties. Customer addition & Usage tracking within TV apps and Cast Receivers, any linking reporting to VIZIO, is the accountability of the separate members.

VIZIO’s JS partner library allows HTML5 application transmission with Smart Cast Displays and Television. Moreover, it supplies entrance to keypresses from remote controls.


Content associates must enlist their apps with VIZIO to use partner library functions. Associates must deliver their HTML5 Television application URL before combining it with the VIZIO framework, as the library employs these references for authentication.


The VIZIO partner library must be examined via the regional server on the display.


The VIZIO library should be added to your HTML5 application via a normal script tag after the app 

 is incorporated. The VIZIO library will radiate a custom event demonstrating that the library is completely packed. Here, the occasion listener must already be in position before adding the partner library.


HTML5 Television Applications should offer a way to leave the app and come back to SmartCast Television that is Home. Pushing the exit button should open the Home bar. Moreover, the partner library provides a role to leave the application.


The partner library allows the handling of remote keypresses in Television applications. HTML5 applications must attend for key-up or down possibilities with the help of usual JS operations. The library does not support the spotting of long or holding down keys. The key up and down key functions will also always be radiated in a quick series.
Here, users can also utilize transport orders via voice command devices. Like, Google assistant, Amazon Alexa, etc. For instance, in case a user says “Alexa, pause the Room’s Television”, the SmartCast medium will supply the command to the activated app. Now, the app should also support all suggested keys to allow voice performance. SmartCast Mobile device possesses a virtual keyboard that can also be employed to put the credentials, or even search queries. Moreover, the apps must support all the keys to promote this service case.


To authenticate the support of given key mappings, VIZIO offers an uncomplicated, web-based means accessible at http://scfs.vizio.com/tools/remote.html. Once you connect your device display, the tool can also be utilized to transmit keystrokes instantly to your Smart Television.


Firstly, when a customer transmits a content launch submission to SmartCast Television via voice or mobile, the request is shared to the medium in the form of a fresh URL. Whenever SmartCast welcomes the fresh URL request, it will take that URL as a unique app launch by default. And this approach shows adequate functionality while launching content for the same app via voice or even mobile. And when the SmartCast medium gets a URL launch demand that corresponds to the application that is currently running. Then the app can block the request and function to project relevant content. This discourages apps from fully reloading each time they get a new request. For instance, launching various content or switching media.


Every content associate app should fulfill accessibility requirements with the help of text-to-speech delivered through Accessible Rich Internet Applications in HTML or even 


If Text-to-Speech operations are promoted via custom events, the display will inform the application. Once the partner library is packed, the system will then radiate a Text-to-Speech event to deliver the initial condition. In case the user revises the Text-to-Speech settings when the app is operating. Then with the help of the same events, the app will be informed.

Numerous smart Televisions show the possibility to incorporate your preferred apps. On the other hand, TVs like Vizio Smart Television offer you endless limitations, while some have specific limitations on their way. These days, you are not gonna discover it challenging to incorporate applications to your Vizio Smart Television.
