Implement file() and folder() helper functions

[AliiiBenn]

Create factory functions for File and Folder construction.

Requirements

Types

type FileConfig = {
  name: string
  content: string
}

type FolderConfig = {
  name: string
  children?: Record<string, File | Folder>
}

Factory functions

const file = (config: FileConfig): File => ({
  type: 'file',
  name: config.name,
  content: config.content,
  createdAt: Date.now(),
  updatedAt: Date.now()
})

const folder = (config: FolderConfig): Folder => ({
  type: 'folder',
  name: config.name,
  children: config.children ?? {},
  createdAt: Date.now(),
  updatedAt: Date.now()
})

Usage example

const root = folder({
  name: '/',
  children: {
    'src': folder({
      name: 'src',
      children: {
        'main.ts': file({
          name: 'main.ts',
          content: 'console.log("hello")'
        })
      }
    }),
    'package.json': file({
      name: 'package.json',
      content: '{"name": "my-app"}'
    })
  }
})

Goals

• Pure functions, no side effects
• Auto-set timestamps on creation
