Next-Gen Way to Connect Redux Store to React Component |

Next Gen Way to Connect Redux Store to React ComponentRedux is one of the widely used State Management Solutions in React Applications Even though it has several upsides one major pain while working with Redux is the huge amount of boilerplate code you need to write to get it set up Adding to the pain is having to use connect function to map the state and dispatch to the React Component Props This article will show you how to use data from the Redux Store in a better way using Hooks Old implementationThe old way implementation of connecting Redux Store to React Applications used connect from react redux to add the selected parts of the store as component props const mapStateToProps state gt select the parts of the state required for example counter state counter count const mapDispatchToProps dispatch gt create the required functions by dispatching actions for example increment gt dispatch actions increment export default connect mapStateToProps mapDispatchToProps Component As you can see that s a lot of code just to get the necessary data and functions Let s now take a look at a more elegant solution Getting Redux Store DataGetting Redux Store Data has been simplified several folds with the introduction of useSelector Hook You can now use the hook to directly get the store data inside the React Component import useSelector from react redux const Component gt const counter useSelector state gt state counter count export default Component Dispatching ActionsJust like useSelector hook there is a hook for dispatch too useDispatch gives you access to the Redux Dispatch function inside the React Component allowing you to dispatch actions from anywhere inside the Component import useDispatch from react redux const Component gt const dispatch useDispatch For Example const increment gt dispatch actions increment export default Component Comparison with connectHooks is obviously the future of React with React urging developers to use functional components over class components but its important to compare the two because as per the use case one approach might fair much better than the other CriteriaHooksconnectDeveloper ExperienceIncredibly Eases the Developer Experience Hooks are really Intuitive making them easier to read and write A lot of additional code is required Adds HOC Higher Order Components thus adding more components to the component tree can be seen in React Dev Tools StabilityMight lead to some rare and avoidable edge cases weird edge cases with useSelector such as Stale Props and Zombie Children For details click hereconnect is way more mature than these hooks and has already worked out these in the older versions of connect leading it to be a bit more stablePerformanceuseSelector accepts a second argument an equality function to determine if the state has changedconnect has some advanced techniques using merge props and other options hidden in the connect function TypeScriptUsing Hooks with TypeScript is a breeze and can be done without much hassleUsing connect with TypeScript is a nightmare often requiring you create multiple interfaces for similar but slightly different itemsTestingTesting Components with these Hooks is tad more difficultTesting the Component Props added by connect is quite easyAs you can see both methods have their merits and demerits It is better to use the method that works better in your use caseNOTE You still need to set up the Redux boilerplate the get the hooks working with React to give you access to the store using the Hooks This method only reduces the extra code for the connection logic Wrapping upIn this article we went over an alternate approach to connecting Redux Store to React Components We also discussed the merits and demerits of this new approach and how it can help developers Hope this helped you in your React Development Journey Thanks for readingWant to work together Contact me on UpworkWant to see what I am working on Check out my GitHubI am a freelancer who will start off as a Digital Nomad in mid Want to catch the journey Follow me on InstagramFollow my blogs for weekly new tidbits on DevFAQThese are a few commonly asked questions I get So I hope this FAQ section solves your issues I am a beginner how should I learn Front End Web Dev Look into the following articles Front End Development RoadmapFront End Project IdeasWould you mentor me Sorry I am already under a lot of workload and would not have the time to mentor anyone Would you like to collaborate on our site As mentioned in the previous question I am in a time crunch so I would have to pass on such opportunities Connect to me on LinkedIn Portfolio Upwork GitHub Instagram |
