# Folder Architecture
|
|
|
|
In this guide, you will explore the details of the project directory structure and how it contributes to the organization and maintainability of Twenty.
|
|
|
|
By following this folder architecture convention, it is easier to find the files related to specific features and ensure that the application is scalable and maintainable.
|
|
|
|
```
|
|
front
|
|
└───modules
|
|
│ └───module1
|
|
│ │ └───submodule1
|
|
│ └───module2
|
|
│ └───ui
|
|
│ │ └───buttons
|
|
└───pages
|
|
└───...
|
|
```
|
|
|
|
## Pages
|
|
|
|
Contains the top-level components that are defined by the application routes. They import more low-level components from the modules folder (more details below).
|
|
|
|
## Modules
|
|
|
|
Each module represents a feature or a group of feature, comprising its specific components, states, and operational logic.
|
|
They should all follow the structure below. You can nest modules within modules; We often refer to them as submodules but the same rules apply.
|
|
|
|
```
|
|
module1
|
|
└───components
|
|
│ └───component1
|
|
│ └───component2
|
|
└───constants
|
|
└───contexts
|
|
└───graphql
|
|
│ └───fragments
|
|
│ └───queries
|
|
│ └───mutations
|
|
└───hooks
|
|
│ └───internal
|
|
└───states
|
|
│ └───recoil-scope-contexts
|
|
│ └───selectors
|
|
└───types
|
|
└───utils
|
|
```
|
|
|
|
### Contexts
|
|
|
|
A context is a way to pass data through the component tree without having to pass props down manually at every level.
|
|
|
|
See [React Context](https://react.dev/reference/react#context-hooks) for more details
|
|
|
|
### GraphQL
|
|
|
|
Includes fragments, queries, and mutations.
|
|
|
|
See [GraphQL](https://graphql.org/learn/) for more details.
|
|
|
|
- Fragments
|
|
|
|
A fragment is a reusable piece of a query, which can be used in multiple places. By using fragments, it is easier to avoid duplicating code.
|
|
|
|
See [GraphQL Fragments](https://graphql.org/learn/queries/#fragments) for more details.
|
|
|
|
- Queries
|
|
|
|
See [GraphQL Queries](https://graphql.org/learn/queries/) for more details.
|
|
|
|
- Mutations
|
|
|
|
See [GraphQL Mutations](https://graphql.org/learn/queries/#mutations) for more details.
|
|
|
|
### Hooks
|
|
|
|
See [Hooks](https://react.dev/learn/reusing-logic-with-custom-hooks) for more details.
|
|
|
|
### States
|
|
|
|
Contains the state management logic. We use [RecoilJS](https://recoiljs.org) for this.
|
|
|
|
- Selectors: See [RecoilJS Selectors](https://recoiljs.org/docs/basic-tutorial/selectors) for more details.
|
|
|
|
- Recoil Scope Contexts: More details will be added soon.
|
|
|
|
We still use React's built-in state management for state that is only used within a component.
|
|
|
|
### Utils
|
|
|
|
Should only contain reusable pure functions. Otherwise, create custom hooks in the `hooks` folder.
|
|
|
|
|
|
## UI
|
|
|
|
Contains all of the reusable UI components used in the application.
|
|
|
|
This folder can contain subfolders for specific types of components, such as `buttons`, `inputs`, or `modals`. Each component should be self-contained and reusable, so that it can be used in multiple parts of the application.
|
|
|
|
By separating the UI components from the other components in the `modules` folder, it is easier to maintain a consistent design and to make changes to the UI without affecting other parts (business logic) of the codebase.
|
|
|
|
## Interface and dependencies
|
|
|
|
You can import other module code from any module except for the `ui` folder. This will keep its code easy to test.
|
|
|
|
### Internal
|
|
|
|
Each part (hooks, states, ...) of a module can have an `internal` folder, which contains parts that are only used within the module.
