React is day to day updating with new features. This post will give some latest best practices for 2020 and easy folder structure.

This is based on my research.

1. My recommendation is not to use expo. If it is really small that will be okay. But if you have too much dependency it will be trouble. If you are planning to use expo, please read a to z about expo. Some third party libraries don’t support expo so you wanted to know how to implement that.

By the way, Expo is a great tool but you want to know all about it. …

What I wanted is give a plan with golang as a job workers . So build very small project initially as a prototype.

Requirements :

1. Language should be golang
2. Wanted to plan without multiple servers(service)
3. Queue management already with rabbitmq
4. Wanted to run concurrently multiple jobs(any no of jobs define)
5. To run a job takes some times (minutes)

Let’s plan how we achieve this.

1. We need to add multiple subscribers for rabbitmq queue.
2. We need to implement rabbitmq acknowledgement (that will help to system pick same job if job not running. Until its acknowledged info will not delete from the rabbitmq queue). …

What is web socket?

Web socket is a communication protocol . It’s bit different TCP protocol from HTTP/HTTPS. Both protocols are located at layer 7. Web sockets are work over http ports 80 and 443 as well as to support http proxies and intermediaries.

Web socket, protocol specification defines is “ws” and when it secure, it will be “wss”

What is Rails cable?

Action Cable seamlessly integrates WebSockets with the rest of your Rails application. It allows for real-time features to be written in Ruby in the same style and form as the rest of your Rails application, while still being performant and scalable. It’s a full-stack offering that provides both a client-side JavaScript framework and a server-side Ruby framework. …

Here we expect to write content pages of xmarin forms in a specific way(Platform specific pages in xamarin forms). If i explain further, there are some views such as where we find it’s difficult to create using xamarin.forms. In those instances we can use this. Let’s learn how we can ….

Before start…

Every Xamarin.Forms control has an accompanying renderer for each platform that creates an instance of a native control. When a ContentPage is rendered by a Xamarin.Forms application, in iOS the PageRenderer class is instantiated, which in turn instantiates a native UIViewController control. On the Android platform, the PageRenderer class instantiates a ViewGroup control. On Windows Phone and the Universal Windows Platform (UWP), the PageRenderer class instantiates a FrameworkElement control. For more information about the renderer and native control classes that Xamarin.Forms …

MVP is an one architectural pattern for separate presentation logic and business logic. I believe when these layers keeping separately from each others is kind on pain.

But to present these kind of implementation we should provide layers across all the application.

Layers
On android development, we have few more layers. It will help to maintains , writing test cases . Lets see about main layers on android development.

1. Domain layer — This is our business logic in mobile application . Data model for rest.

2. Model Layer — database connection related things

3. Presentation or app layer — android related part (android UI kit related . e.g. …
