For example, let's say every React component has a test and a style file: One can already see that this doesn't scale well, because with every additional component in the src/ folder we will lose more sight of every individual component. Se stai avviando un progetto, non spendere pi di cinque minuti per scegliere una struttura di file. And then there's the really big issue: refactoring. All Rights Reserved. These two extend the Airbnb rules. UI components). This helps the application to stay healthy and scalable as it grows. If we open it up, we see something a bit curious: This is essentially a redirection. It's possible to manage these conflicts, but it's a big pain. Learn React like 50.000+ readers. Small React(ion): From Kanji to Hiragana. instead of re-rendering the only parent container with its three children.
I don't want that. I've worked one-on-one with tons of developers, answering their questions and helping them get unstuck. From here, it becomes more interesting yet also more opinionated. For further actions, you may consider blocking this person and/or reporting abuse. Are there any best practices for this? Every React component grows in complexity eventually. Updated on Aug 6, 2021, (I have updated my react structure, you can read it here: https://dev.to/djamaile/how-i-structure-my-react-ts-applications-2021-145j). colors, font sizes, breakpoints), but I also store public keys and other app data here. When this happens sometimes a container is better off as a regular component with Button), others are more feature related (e.g. makes refactors more painful, so it might be smarter to connect the child components in this case and leave the
Help Provide Humanitarian Aid to Ukraine. To type the mapStateToProps and mapDispatchToProps functions in the container we want to export types created by using Pick. Naturalmente, questa solo una raccomandazione e potrebbe non essere rilevante per il tuo progetto. It will become hidden in your post, but will still be visible via the comment's permalink. In contrast, I encourage you to apply your personal touch to it. Files can contain as many components as you'd like! It simplifies imports. Feel free to poke around and see how things are structured!
Why not use an established utility library, like lodash? I want to be able to write this: Next: when I'm working in my IDE, I don't want to be flooded with index.js files. Lastly, the theme folder and the theme folder is for Material-UI. There are other bundlers, but most common tools (eg. They're collected in the src/hooks directory. How should you structure the files and directories in your applications? Questo principio chiamato colocation. So once we add a new property to the IDefaultProps interface, TypeScript is not going to let us compile until we go to the component and add a default value to it. Each component has it's own directory, with a component file, a styles file, and its typings and tests. Detto questo, ci sono alcuni approcci popolari nellecosistema che potresti prendere in considerazione. This gives us another vertical layer for creating folders for other technical categories. For example, this one moves the user's cursor within a text input: And this utility gets the distance between two points on a cartesian plane (something that comes up surprisingly often in projects with non-trivial animations): These utilities live in src/utils.js, and they come with me from project to project. So, I just made a graph folder within components and different views shared the graph components. Moreover, if you are not using CSS but something like Styled Components, your file extension may change from style.css to style.js too. Are you sure you want to hide this comment?
Every developer on the project will have their own conceptual model for what should go where, and I'll need to spend time acclimating to their view. The next step will help you to structure midsize to large React applications. Probabilmente vorrai ripensarci comunque dopo aver scritto del codice reale. For VS Code, we can add our aliases in jsconfig.json. I created an NPM package, new-component, which does all of this for me automatically. Whenever I want to create a new component, I need to generate: Fortunately, I don't have to do any of that manually. When I execute this command, all of the boilerplate is created for me, including the basic component structure I'd otherwise have to type out! Most React projects start with a src/ folder and one src/App.js file with an App component. In my experience as a React freelancer many React projects follow this organization of a React application. Therefore I have a folder called types where I can put in my Typescript types and interfaces. In this case we can reuse IProps instead of creating StateProps. But when I use Next.js, I do have /src/pages, with top-level components that define the rough structure for each route. The strutures of the application's redux state tree and the /app directory tree must be very similar if done right. Una modalit comune per strutturare i progetti posizionare file CSS, JS e i test in cartelle raggruppate per funzionalit o percorso. Why don't we have a separate /components and /containers folders like everyone else? What if I have a function that will help me accomplish some goal for the project, not directly tied to a specific component? Well, then our editor will fill up with index.js files! A domain may contain child domains or subdomains (domains that are only used by or relevant to their parent domain). https://dev.to/djamaile/how-i-structure-my-react-ts-applications-2021-145j, https://github.com/djamaile/react-boilerplate-2020, How to setup husky, eslint and prettier within minutes, How I structure my React /TS applications (2021). Also some components don't have own props or don't map any prop to dispatch, in those cases there's no point in exporting OwnProps or DispatchProps. Often, the boundaries are blurry, and different developers will make different decisions around what should go where.
It'll get moved over to src/helpers. They're only needed when I'm working on the FileViewer component, and so I should only see them when I'm working on FileViewer. Here's my file, as an example: So, that's how I structure my React applications! The biggest issue is that Webpack aliases are non-standard. Let's start by talking about my priorities, the things I've optimized for. It's not uncommon for large projects to have thousands of React components. Alright, so you'll notice I choose to do two things here: I'll be honest: I don't have a good reason for making these decisions. It's an incredible time-saver, and in my opinion, it totally nullifies this drawback. Webpack is the bundler used to package up our code before deployment. Sometimes I do, if it's not something I can easily build myself. You'll be the first to hear about course updates, as well as any new blog posts I publish! Sometimes, a complex component will have a bunch of associated files. A utility is a generic function that accomplishes an abstract task. If you want to build a component library with Storybook, or create unit tests with Jest, these tools will need to be configured to understand your Webpack aliases. A meno che tu non abbia una ragione convincente per usare una struttura di cartelle profonda, considera di limitarti a un massimo di tre o quattro cartelle annidate in un singolo progetto. Pretty much every function in the lodash library is a utility, according to my definition. Usually when a bug is found, or a refactor is needed, it involves all the redux parts in a domain: For example, at some point you may have reusable React Hooks that can be used by more than one component. child containers instead: Say
If you follow my function-based approach, it means you'll have an enormous set of unorganized components sitting side-by-side in src/components. To be fair, it is possible to avoid this worst-case scenario, but it's a lot of extra work for relatively little benefit, in my opinion. The second step follows the rule: Multiple files to rule them all. Furthermore, we have the famous components folder. In this blog, I have about 50 generalized, reusable hooks. Easy refactor. After all, this step is just about bringing the features together which allows teams in your company to work on specific features without having to touch files across the project. For every React project, I use Material-UI. I'll be honest, it's not my best work. It's too early to share much yet, but if you'd like to follow along, the best way is through my newsletter. I'm a freelance fullstack developer transitioning to Web 3. Exceptions prove the rule though. In addition, this is nothing I could tell my consulting clients when they ask me about this matter. You could also leave out the folder and put the ErrorTracking/ folder directly into Error/. Not only because more logic is added (e.g. more JSX with conditional rendering or logic with React Hooks and event handlers), but also because there are more technical concerns like styles and tests. Learn React by building real world applications. That's when we transition to step two. This directory contains all the redux modules of the application. I'm able to spend my time doing what I like: building quality user interfaces. At a higher scale of teams, it becomes tricky to "just move files around without a clear vision". The names of the folders are again up to you: If one of the feature components (e.g. But here's the problem: real life isn't nicely segmented like this, and categorization is actually really hard. Eventually, the features in the codebase will be conceptually organized around a product that no longer exists, and so everyone will just have to memorize where everything goes. I'm a Front-End Software engineer who will be responsible for the complete lifecycle of scalable, secure, and well-designed software products from research and design to implementation. The theme you're using is beautiful, colours really popup. At least you know exactly where to look! With Material-UI we can also create a custom theme and that is what we do in the theme folder. for that specific domain will live inside. For a while, a popular ESLint rule warned against defining more than one component per file. No, not all the components folders are 1:1 to the views folder. My rule of thumb is that I am never nesting components more than two levels, so the List and ListItem folders as they are right now would be alright, but the ListItem's folder shouldn't have another nested folder. Like in the example above, in a perfect world, we would be using a kebab-case naming convention for all folders and files, because PascalCase named folders/files are handled differently in the diversity of operating systems which may lead to bugs when working with teams using different OSs. An online course that will teach you how to build complex, rich, whimsical, accessible applications with React. And it makes it easier to quickly get a sense of how the app is structured. That said, I do generally find myself pulling non-trivial components into their own files, once I have the basic functionality working. Every approach prioritizes different things, makes different tradeoffs. The first step follows the rule: One file to rule them all.
