Create your Saga with Redux-Saga

After reading this blog, you will be able to understand the brief about what is redux-saga. Also you able to install, configure, and create the basic saga in your application. So, before we get any deeper, it’s important to note, that the actual term “saga”.

A saga in general programming series of reversible transactions, the saga is designed to replace single huge, locking transactions.

eg: Deposit in a bank would require a change in different spreadsheets, the traditional way requires locking all these spreadsheets changing a value then unlocking them

Whereas in functional programming, in the saga, you can break the transactions into small steps, and if there was any error along the way you can reverse all the steps that you’ve taken. Now, to manage all this, saga uses a process manager to keep track of what’s been done and what other actions need to be taken.

What is Redux-Saga?
Redux-saga is a redux middleware library, that is designed to handle side effects in your redux app nice and simple. It achieves this by leveraging an ES6 feature called Generators, allowing us to write asynchronous code that looks synchronous, and is very easy to test.

Channels in Redux-saga

What are the channels? Are they useful to us in day to day programming? We’ll be going through this blog that channels are played really a major role in redux-saga.

Channels:
Channels are of 3 types which are used to perform 3 different things, here I will brief you about those channels here but will explain in detail a bit later.

  • Action Channels: Action channel is a buffer, it stockpiles actions which sagas can consume one by one.
  • Generic Channels: Generally, we use Generic channels to communicate between two sagas. This can be done through the Actions but the idea of a channel is that communication is limited interest in sagas without other sagas being privy to that information.
  • Event Channels: Event Channel is completely different used to wrap outside event sources. we can consider web socket as a good example of the Event channel.

A Complete Process to Create an App in 2021

It’s 2021, everything is getting replaced by a technologically emerged ecosystem, and mobile apps are one of the best examples to convey this message.

Though bypassing times, the development structure of mobile app has also been changed, but if you still follow the same process to create a mobile app for your business, then you are losing a ton of opportunities by not giving top-notch mobile experience to your users, which your competitors are doing.

You are about to lose potential existing customers you have, so what’s the ideal solution to build a successful mobile app in 2021?

This article will discuss how to build a mobile app in 2021 to help out many small businesses, startups & entrepreneurs by simplifying the mobile app development process for their business.

The first thing is to EVALUATE your mobile app IDEA means how your mobile app will change your target audience’s life and why your mobile app only can be the solution to their problem.

Now you have proposed a solution to a specific audience group, now start to think about the mobile app functionalities, the features would be in it, and simple to understand user interface with impressive UI designs.

From designing to development, everything is covered at this point; now, focus on a prelaunch marketing plan to create hype for your mobile app’s targeted audience, which will help you score initial downloads.

Boom, you are about to cross a particular download to generate a specific revenue through your mobile app.

How to implement Redux Saga with ReactJS and Redux?

Intro to Redux setup tutorial

Very often, you can hear about the state in frontend applications, but what it exactly is? Let me explain.

State in frontend applications represents all the data stored in the application in a given time. It can be stored in different formats like objects or strings. Based on the state’s values, we can personalize the application, display, and hide certain elements.

To manage the state in modern frontend frameworks, we can use different libraries like Redux, MobX, or NgRx. The most common one is Redux, which is used mainly with ReactJS applications, although it’s possible to use it with Angular as well.

With Redux, the state of the application is kept in the store, and we can access the store from every component in the application. Redux consist of store, reducers, and actions.

In this article, I’d like to tell you more about the Redux library and create a simple ReactJS project, where I’ll set up a Redux step by step.

Let’s start!

How does Redux work?

Redux is based on the flux architecture, and it supports unidirectional data flow. It means that data in the application goes through the same lifecycle over and over again, which makes everything that happens in the state more predictable.

Let’s take a look at the simple graphic, which illustrates the data’s lifecycle in the Redux application.

Image for post

On the graphic above, you can see that from the UI, we trigger an action that passes the data to the reducer. Next, the reducer updates the store, which is the state of our application. The store defines the user interface.

Let’s think of the benefits which using Redux can bring to our development.

Benefits of using Redux

When you’re building the application, you know more or less how much data you will need to manage inside the application. In most cases, frontend applications have some functionality, and very rare they are just static websites. Commonly, we keep some user data, forms data, etc. inside the application state, and then it’s very useful to use a tool for managing the state.

The most popular solution in ReactJS applications is Redux. There are some important benefits to the popularity of this solution. Let’s take a look at them one by one.

  • predictable state — The state in Redux is predictable because reducer functions are pure; therefore, if we pass the same state and the same action, it needs to return the same result. Redux state is also immutable; it can’t be changed or modified.
  • easy to maintain — Considering that it’s predictable and very strict about the structure of the Redux application, anyone who knows Redux will understand it and work with it easily.
  • easy to debug — Redux allows us to log the behavior using available developer tools, makes debugging easier.
  • developer tools available — Redux has amazing developer tools, that can be used in the browser to see what’s happens in the backend.
  • server-side rendering — Redux supports server-side rendering by allowing to manage initial rendering. Redux sends the state of the application to the server with a response to the server’s request.

Above I listed a few benefits of using Redux to manage the state of your frontend application. Now, I’d like to go to the practical part, where we are going to set up a Redux with ReactJS application.
