Steps To Develop A Karaoke App

Have a detailed look at how to make a Karaoke app. Such a project involves the following steps:

1. Define a project scope

Define project scope by deciding which platform to launch your apps, such as Web app development, Android or iOS development.

Consider hybrid app development over native app development if you want to target multiple platforms while publishing your karaoke app.

2. Select an appropriate project methodology

Selecting an appropriate project development methodology depends on your needs and requirements. There are two popular app development methodologies, i.e., waterfall and agile. Know more about Agile vs. Waterfall methodology; which is best?

Also, consider launching the MVP version of your karaoke app to minimize app development duration and cost.

3. Onboard a project team

Your team will need the following roles in your project: Business analysts (BAs), UI designers, and Web developers with experience in Node.js, Android developers with Kotlin expertise;

iOS developers with Swift skills, Testers, and A project manager (PM).

Consider using the Scrum technique, which is useful for agile projects where iterations are classified as “sprints,” and the project manager will act as a Scrum master. 

The scrum master will create a small team known as “Scrum Teams” to facilitate the development process of karaoke app development.

4. Work on a development strategy

The utilization of managed cloud service providers will facilitate you with better infrastructure management. 

Therefore consider using market-leading software development kits (SDK) and (Application Programming Interfaces) API to extend the features and functionality of your app, such as video recording, music streaming, payment gateway integration, etc.

5. Start web app development

Consider implementing Platform as a Service development model for web development. This procedure will offer the following advantages: offering management for the entire cloud infrastructure, including storage, networking, servers, etc.

Moreover, this development model will offer operating systems,  runtime environments, middleware, etc. Platform as a Service provides (Application Programming Monitor) APM which facilitates developers with auto-scaling, databases, and other services.

The platform as a service will enable developers to integrate third-party API to extend the features and functionalities of the karaoke app.  

6. Use managed cloud services for the mobile app backend

It takes more time and energy to manage the mobile back-end development. However, you can use the mobile backend as a service MBaaS to simplify the development process.

The MBaaS will facilitate the following advantages to the developers such as:

• Implementing features like push notifications, security, and user management becomes easier with the MBaaS platform.
• Easier scaling of the karaoke app
• Lowering down the complexity of API integration for various mobile platforms and devices.

7. Sign-up for Spotify SDKs/APIs

Spotify is a good solution for offering your users a wide range of songs. Consider implementing Spotify web API for web app development and extending features such as song recommendations, audio analysis, playback, playlists search, etc.

Moreover, Spotify also offers SDK both for Android and iOS app development.

8. Implement video recording SDKs/APIs

The recording feature is a crucial element of the karaoke app, enabling users to record their songs to collaborate with friends.

Therefore, there is a requirement for an appropriate video recording solution for your app. So, consider adding video recording SDK/API from third-party providers like Twilio.

The video platform will facilitate the following advantages to your platform.

• Video recording, peer-to-peer collaboration, group rooms, screen sharing, and several other useful features.
• SDKs for Android and iOS in addition to their JavaScript SDK for web app development.

9. Buy a cloud streaming solution

A high-quality, low-latency cloud streaming solution is a must for cloud streaming solutions. Wowza can be an ideal solution for the following reasons:

• The platform offers high-quality and low-latency video streaming solutions.
• Wowza also offers GoCoder SDKs for Android and iOS for free with their cloud streaming solution.
• You can use their JavaScript API for web app development

10. Integrate an eCommerce solution

Consider implementing an eCommerce solution for enabling your users to make in-app purchases from your karaoke app. Consider adding Shopify API to avail the eCommerce functionality. Shopify APIs and SDKs will enable your platform to leverage the entire range of e-commerce features. 

11. Sign-up with a payment gateway provider and SMS solution

Payment gateways are another crucial feature you will need for your karaoke app. Consider implementing Braintree API from Paypal. Brain Tree is an online payment solution with features like data security, fraud protection, reporting, etc. 

Moreover, Braintree will enable your users to use PayPal and debit/credit cards on your karaoke app. 

For an SMS solution, consider integrating Twilio into your app.

12. Start web app development

Web development is the best way to extend the scalability of your karaoke app. Consider using Node.Js for starting web app development. Node.Js is an ideal choice for developers because of the following reasons:

• Node.Js is easy to use for most developers because of their familiarity with JavaScript language.
• A large and growing community of developers 
• A diverse range of sharable tools and frameworks for an open-source runtime environment. 

Consider the following things for web app development

• Utilise database resources in accordance with your needs. 
• Integrate Shopify eCommerce, Spotify, Wowza streaming cloud, Twilio video, Twilio SMS, Braintree payment gateway, and Twilio into the app.
• Perform web app testing and deployment.

13. Use Kotlin for Android app development

Kotlin is the most used modern programming language among Android developers. The use of Kotlin facilitates the following advantages.

• Open-source language
• The concise syntax of this open-source language reduces coding effort.
• Interoperable with Java Programming languages and their libraries
• Helps developers to prevent common errors like null pointers exceptions

14. Develop, test, and deploy the Android app

Consider utilizing Android Studio to test and publish your app. Android Studio is a popular “Integrated Development Environment” (IDE) for Android development. 

The platform fully supports Kotlin, music library, video recording, streaming, eCommerce payment gateway, and bulk SMS SDKs/API into your app.

15. Code, test, and deploy the iOS app

Consider Swift programming language for iOS development. Swift programming language offers the following advantages to app developers such as.

• Apps written in Swift are fast.
• Swift offers powerful features like string concatenation, generics, and operators.
• Codes written in Swift are easier to maintain

16. Manage the project using effective tools

Consider implementing the Scrum Team framework to your development project. The product owner, called “Product Backlog,” will provide requirements in a document.  The Scrum Master will hold a “Daily stand-up meeting” to collect project status and resolve any issues. 

There will be requirements for an effective project management tool to manage all these activities. Trello will be a great choice for an effective project management tool.
