海外TECH	DEV Community	Use React Props like a Pro !	https://dev.to/suchintan/use-react-props-like-a-pro--1gll	Use React Props like a Pro Table of ContentIntroductionReact PropsPro TipsReduce HTML RedundancyCommunicate between Parent and ChildTriangular communication between Parent and ComponentsThank you Introduction Hello amazing developer ‍ before digging into this topic let me give you a small introduction and so instructions Don t worry it would be quick and crisp I am Suchintan Das a Full Stack Developer currently working over two startups I have been into web development for past two years Connect me on LinkedinThe whole syntaxes and code are uploaded on this Repository If you find it useful you can star the repository to show a appreciation Thanks React Props I know most of you can t wait to know what s there on this amazing blog but let s just take a small breath understand a little bit about React Props It s very similar to inheritance where some properties are passed from parent to child Yes in case of props also it s a one way path Pro Tips Reduce HTML Redundancy Yes you heard it write you can actually send HTML to your child like any card body section body or headings Here s a small example of it Parent jsximport React from react import Children from Children import stylesheets Part Parent css const Parent gt const card title gt lt div className card gt lt img src alt gt lt button gt title lt button gt lt div gt return lt gt lt div className container gt lt h gt Showing childrens lt h gt lt br gt lt div className cards gt lt Children childcard card Child gt lt div gt lt div gt lt gt export default Parent Children jsximport React from react const Children props gt return props childcard export default ChildrenThe card is defined in the parent component and it sent it to child component to use which reduces the reductant code in the first place taking reusable components to another level Communicate between Parent and Child I know most of the people while working over any website comes through a scenario where they want to get changes in parent based on changes on child component Here s an example let us take you are building a website with dark and light mode switching and you put the controller on the parent body and the child component section The idea here is using pointers Yes you heard it right We know that the communication of props is a one way process so after the props are sent there is no returning back of it even if there are some changes that occurred To solve this issue we will send our states pointer to the child Therefore any change in the value would mean change on the pointers address which would help use manipulate parent and child together YES Here s a small code peak Parent jsximport React useState from react import stylesheets Part Parent css import Children from Children const Parent gt const dark setdark useState false const tooglemode gt dark setdark false setdark true const darkmode lt i className dark fa solid fa moon toogle active fa solid fa moon toogle inactive onClick tooglemode gt const lightmode lt i className dark fa solid fa sun toogle active fa solid fa sun toogle inactive onClick tooglemode gt return lt div className dark application dark application light gt lt div className buttoncontroller gt lt h gt Website lt h gt lt div className toogle gt darkmode lightmode lt div gt lt div gt lt Children dark tooglemode tooglemode gt lt div gt export default Parent Children jsximport React from react import illustrator from assets images illustrator svg const Children dark tooglemode gt return lt div className section gt lt img src illustrator alt gt lt div className sidebar gt lt h gt Welcome lt h gt lt p gt Lorem ipsum dolor sit amet consectetur adipisicing elit Cupiditate quod cum quibusdam rerum quis repellat consequuntur nesciunt deserunt Voluptates aut eaque sed rerum dolorem alias quia Quo magni hic odio exercitationem ratione lt p gt dark lt button onClick tooglemode className light style border px solid black gt Dark Mode lt button gt lt button onClick tooglemode className dark gt Light Mode lt button gt lt div gt lt div gt export default Children And a short demonstration of the same Triangular communication between Parent and Components Yes I know that s something very exciting Though the concept would remain same as earlier the only play here is that all the states that needs to be manipulated would be defined on the Parent Component and their pointers would be sent to all the childs As a change is done on the pointer s address all the components would be accessing the data from the same address result being passed on all the of them Let s have our peak on the code Parent jsximport React useState from react import stylesheets Part Parent css import Children from Children import Children from Children const Parent gt const show setshow useState true const count setcount useState const toogle gt show setshow false setshow true const maintaincount event gt event target id add setcount count count count length setcount count slice return lt div className application container gt lt div className header gt
