1. Public URLs vs Signed URLs

Supabase buckets can be public or private. By default, getUrl() fetches the public URL if the bucket is configured as public in Supabase.

import { Storage } from '@quatrain/storage'
 
async function getImageUrl(imagePath: string) {
    const storage = Storage.getAdapter('supabase')
    
    // Will return https://xxx.supabase.co/storage/v1/object/public/images/...
    const publicUrl = await storage.getUrl('images', imagePath)
    
    return publicUrl
}

2. Uploading assets

Uploading an asset to Supabase storage behaves exactly like other adapters.

import { Storage } from '@quatrain/storage'
 
async function saveDocument(buffer: Buffer) {
    const storage = Storage.getAdapter()
    
    await storage.put('secure-documents', 'user-1/contract.pdf', buffer, {
        contentType: 'application/pdf'
    })
}
