海外TECH	DEV Community	Organize large React Applications like this	https://dev.to/darshancodes/organize-large-react-applications-like-this-1pgk	Organize large React Applications like thisHey there guys Welcome to this blog In today s blog we ll be going to see how we can organize our large ReactJS Apps so as we ve seen that most of peoples are now using ReactJS as there primary frontend library to create different kinds of websites and web applications Also One of the best features of React is how it gets out of your way and is anything but descriptive when it comes to file structure Therefore you ll find a lot of questions on Stack Overflow and similar sites asking how to structure applications This is a very opinionated topic and there s no one right way In this article I ll talk you through the decisions I make when building React applications picking tools structuring files and breaking components up into smaller pieces etc Folder StructureLet s view the folder structure of the react application As you can see in this image there s a folder structure of your react app Well So your all the code is present in srcTo keep things organized I ll place all application code in a folder called src This contains only code that ends up in your final bundle and nothing more This is useful because you can tell Babel or any other tool that acts on your app code to just look in one directory and make sure it doesn t process any code it doesn t need to Other code such as webpack config files lives in a suitably named folder For example my top level folder structure often contains src gt app code herewebpack gt webpack configsscripts gt any build scriptstests gt any test specific code API mocks etc Also the one file named index html package json and any dotfiles are configuration files React ComponentsOnce you ve got a src folder the tricky bit is deciding how to structure your components In the past I d put all components in one large folder such as src components but I ve found that on larger projects this gets overwhelming very quickly The one thing to get this understanding easier is to group the components it means categorizing the components based on their commom properties like where it should be amp why it should be there makes the component look clean neat and understandable For example you have an component that renders the buy product cost let s call it BuyProduct you might simply prefer to use it as Product cuz you ll then import it from the Buy folder import Product from buy product VSimport BuyProduct from buy buy product Prefer JSX ExtensionA lot of people name React components with a capital letter in the file to distinguish them from regular JavaScript files So in the above imports the files would be BuyProduct js or Product js I tend to prefer to stick to lowercase files with dashes as separators so in order to distinguish I use the jsx extension for React components Therefore I d stick with BuyProduct jsx You can enforce this jsx convention using a rule from eslint plugin react Prefer using Prop TypesReact allows you to document the names and types of properties that you expect a component to be given using its prop types package By declaring the names and types of expected props along with whether or not they re optional you can have more confidence that you ve got the right properties when working with components and you can spend less time debugging if you ve forgotten a property name or have given it the wrong type You can enforce this using the eslint plugin react PropTypes rule ConclusionHope you have understood ow you can manage your larger react applications with this short amp simple article One of the best features of the framework is how it lets you make most of the decisions around tooling build tools and folder structures and you should embrace that This article has given you some ideas on how you might approach your larger React applications but you should take my ideas and tweak them to suit your own and your team s preferences Let s connect on Twitter D	2022-02-20 05:38:37
