Utility to quickly generate layers, slices, and segments from [Feature-Sliced Design](https://feature-sliced.design).

## Installation

```bash
npm add -g @feature-sliced/cli
```

This will create a global binary `fsd`. You can install this CLI locally as well, but then you will need to use `npx` to run it.

## Usage

Generate the Entities layer with a `client` slice that contains an index file and two segments, `ui` and `api`:

```bash
fsd entities client --segments ui api
```

Or, for short:

```bash
fsd e client -s ui,api
```

If you have at least one slice in your project already, the CLI will know where to generate. Otherwise, it will generate in the current folder, or you can specify the location yourself with the `--root` or `-r` option.

Other examples

- Generate the Widgets layer with a `bottom-bar` slice that has an index file and segments `ui` and `api` in the `src/` folder:

```bash
fsd w bottom-bar -s ui api -r src
fsd widget bottom-bar -s ui,api -r src
fsd widgets bottom-bar --segments ui,api -r src
```

Produces:

- `src/widgets/bottom-bar/index.(js|ts)` (depending on your project)
- `src/widgets/bottom-bar/ui/`
- `src/widgets/bottom-bar/api/`

- Generate the Features layer with a slice `employee/employee-record` inside a slice group `employee`:

```bash
fsd f employee/employee-record
fsd feat employee/employee-record
```

In a detected FSD root[^1] or current folder, produces:

- `features/employee/employee-record/index.(js|ts)` (depending on your project)

- Generate the Entities layer with a `user` slice inside the `src/lib` folder, creating it if necessary:

```bash
fsd e user -r ./src/lib
fsd entity user --root ./src/lib
```

Produces:

- `src/lib/entities/user/index.(js|ts)` (depending on your project)

- Generate the Pages layer with slices `edit-note` and `note-list`, each containing segments `ui` and `api`:

```bash
fsd p edit-note note-list -s ui, api
fsd page edit-note, note-list -s ui api
```

In a detected FSD root[^1] or current folder, produces:

- `pages/edit-note/index.(js|ts)` (depending on your project)
- `pages/edit-note/ui/`
- `pages/edit-note/api/`
- `pages/note-list/index.(js|ts)`
- `pages/note-list/ui/`
- `pages/note-list/api/`

- Generate the Shared layer with segments `ui` and `api` and an index file for each segment:

```
fsd s ui api
fsd s -s ui api
fsd shared ui -s api
```

In a detected FSD root[^1] or current folder, produces:

- `shared/ui/index.(js|ts)`
- `shared/api/index.(js|ts)`
