There is no official way to structure your apps. Here's what they shared with us: #1: Don't overthink the application structure and avoid using too many nested files and folders React is the most popular JavaScript library for building user interfaces.

All the action types are declared in the types file. We could continue for a bit and clean up the folder structure within a feature. So, here is my best react folder structure for scalable applications. Contexts Plain React in 200+ pages of learning material. We pass the function that triggers the state changes as a prop from the container and call the function inside the Presentational Component. Having all this written, I hope it helps one or the other person or team structuring their React project. But what if we need to trigger a state change when we click a button in the Presentational Component? Best practices are followed for doing projects in the right structure. This looks pretty simple. Now let me explain the react folder structure which Im following to develop a new application. 1. What is React? separate folders for components, contexts, hooks), grouping by pages with global folders for contexts, hooks, etc, grouping by pages with colocation of related components, contexts, and hooks. The names of the folders are again up to you: If one of the feature components (e.g. If we don't use layout then we need to write code like for the navbar, header, footer, component whenever requires.

Eventually you'll have a common folder for the global components which are re-used along the project like buttons or dialog-boxes. Job Ad: "We're looking for a Junior React dev, Evolution of a React folder structure and why to group by features right away, # I'm omitting the files inside most folders for readability, # no idea what this does but I couldn't leave this folder empty, # again no idea what this does but I couldn't leave this folder empty, # this modal shows a form to edit a todo item, # here is the form that is shown by the modal, # the edit modal is shown on top of the todo list, # colocate -> todo-form is only used by edit-todo-modal, # colocate -> todo-item is only used by todo-list, # group simple ui components in one folder, # this is where the todo-list is now shown, # the form is now shared between create page and edit modal, # the form is shown on the home and create todo page, # we could also ungroup this folder to make the components folder flat, # colocate -> the edit modal is only used on the home page, # imagine more contexts here, # not much left in the global hooks folder, # colocate -> this hook is only used by the todo-list component, # is now shared between home and project page, # shows now a list of projects and an overview of all todos, # shows a list of todos belonging to a project, # the todo "feature" contains everything related to todos, # this is used to export the relevant modules aka the public API (more on that in a bit), # the public API of the component (exports the todo-list component and hook), # all that's left in the pages folder are simple JS files, # each file represents a page (like Next.js), # this is used to export the relevant modules aka the public API, "@features/todo/todo-list/todo-list.component", Tania Rascia suggests a similar folder structure, Max Rozen uses a similar folder structure.

We reached out to several Reactjs experts and contributors to find out the practices they follow to scale large web applications. Unless you have a very compelling reason to use a deep folder structure, consider limiting yourself to a maximum of three or four nested folders within a single project.

Furthermore, if a service from the previous section is tightly coupled to a feature, then move the service to the specific feature folder. Containers/Stateful Components are the components which have a direct subscription to the state of the app, likely a store. With a growing codebase, this makes it a lot harder to track down dependencies between files and promotes intertwined code. Then there's an assets folder where static assets can be placed. 2021 ooloo software UG - All rights reserved. For example, I would go with the following folder structure: While the src/List.js file would have the implementation details of the List and ListItem components, it would only export the List component from the file as public API of this file: Next the src/App.js file can import the List component and use it: If you would take this one step further, you could also extract the ListItem component into its own file and let the List component import the ListItem component: However, as said before, this may take it too far, because at this point in time the ListItem component is tightly coupled to the List component and therefore it would be okay to leave it in the src/List.js file.

But if your project is likely to only have a single layout, this directory might not be necessary. You get the point: The global hooks and contexts folders get crowded.
