React — Redux workflow in 4 steps — Beginner Friendly GuidePhoto by Lukas at Pexels.comRedux allows you to manage the state of the application via a unidirectional flow where a child component child component can directly access the state from the redux store instead of getting state changes from parent components.I am assuming you have basic knowledge of React and an understanding of what Redux is used for.

ReduxI have worked on a couple of projects which had Redux, and i see there is a lot of confusion among people who are getting started. My opinion is if we understand “what problem is redux trying to solve” and “responsibilities of the core components of redux”, life will be easier. This post is my attempt on trying to explain these things.The Problem…SPAs(Single Page Applications) these days are pretty complex and they maintain a lot of state in the front end, e.g: api responses, cache data, state of the #ui widgets like spinners and progress bars, etc..Usually we have Models which hold the data and Views which render them. A View can update a single Model or multiple Models, a Model can update another Model and based on these Model changes Views get updated. Because of all these (...)

Scale Your #react Web Application with Redux MiddlewaresWhen it comes to state management in React, Redux is quite popular and does the required job efficiently. Though dispatching actions and updating the store with reducers works great with simple Web Applications, Redux provides a powerful functionality of middlewares which makes your life easy in building a large scale web application.It provides a third-party extension point between dispatching an action, and the moment it reaches the reducer.As the documentation suggests, Redux middlewares work in a similar manner as express middlewares do ( if you come from server-side ). Someway between Action Creators and Reducer, the Middleware intercepts the action object before Reducer receives it and gives the functionality to perform (...)

No-boilerplate global state management in #react

When your React application reaches a certain size and scope, attempting to manage state within component instances adds too much complexity, prop drilling, and code smell. Developers inevitably turn to global state management tools, such as MobX or #redux, to solve these problems and make their lives simpler. I strongly endorse Redux and use it in my personal projects, but not all developers share my sentiment.I have worked on quite a few large projects that have demanded a global state powerhouse behind the React UI. No matter application size, team size, or member seniority, the almost universal opinion of these global state management packages has been overwhelmingly negative.The top two complaints? Boilerplate and learning curve. While these packages solve a lot of problems and (...)

As the scope, size, and feature set of your React + Redux application grows, so does the pain of maintaining it, especially when you’re working with a big team, and multiple people work on each feature in your application. In this article, we are going to be exploring how to organize your codebase, to increase maintainability and extensibility.When you first start writing a new React application, the feature set is small, and the React API is simple, yet flexible and powerful enough to handle state management. Eventually however, your application grows bigger, and the shortcomings of React’s setState at handling state management for larger applications become obvious, in a painful manner.So you do a bit of research and figure out Redux is your best bet at handling the growing state (...)

How to screw up a React project and possibly even want to give up on the library altogether.As I was wrapping up this post, my six-year-old daughter asked what I was doing. I told her I was writing about how sometimes people build software the wrong way. She gave me a confused look: “Why would anyone want to do that!?”The reality is that no one ever starts a project with the intent to fail, but as I have worked with React for the past several years, I have seen a few common patterns of failure in both myself and those around me.

Tired of debugging type errors in your state? Want up-to-date documentation for your React apps? Read on!Side effects of type errors: Lost dev time and increased irritabilityWhen I first encountered TypeScript, I felt a decent amount of despair: Why did I have to write what felt like more boilerplate code? When using it with React, why did I have to determine the type of every single React prop, and the request and response objects for async calls? And what the hell were intersection and union types?After spending time working with TypeScript, however, I quickly fell in love with it. It saves me from wasting time on dumb type errors, provides dynamic self-documentation, and makes it far easier for my colleagues to understand the expectations set for the code at first glance.My interest (...)
