@blobber/react-native v0.2.0

What is Blobber?

Blobber is an image management platform for React apps including:

• An image upload hook
• Managed file storage
• on-the-fly image optimization
• global CDN distribution

It's the fastest way to add production-ready user-uploaded images to any React app.

Install

npm install @blobber/react

yarn add @blobber/react

Configure

Before you get started, you'll need a clientId to identify your app. Log in to the dashboard to get one for free, or use "SANDBOX" to get started right away.

Upload an Image

The useUpload hook provides everything you'll need to start accepting image uploads.

• handleUpload → handler for onChange event of <input> element
• previewUrl → local url for the uploaded image
• file → FileData object describing the uploaded image

import { useEffect } from 'react'
import { useUpload } from '@blobber/react'

function ImageUploadButton() {
  const { handleUpload, file, previewUrl } = useUpload({
    // your app's Client ID
    clientId: 'YOUR-CLIENT-ID-HERE',
  })

  useEffect(() => {
    if (file) {
      // save the file.id to your server
      api.post('/user', { photoId: file.id })
    }
  }, [file])

  return (
    <div>
      <img src={previewUrl} />
      <input type="file" onChange={handleUpload} />
    </div>
  )
}

Once the image is successfully uploaded, save file.id to your backend/server. Usually, you'll want to associate it with the authenticated user.

Serve an Image

To serve an image, pass the file.id you saved in the previous step to the getUrl function along with any transformations.

import { getUrl } from '@blobber/react'

// pass saved photo ID to profileImage component
function ProfileImage({ photoId }) {
  const imageUrl = getUrl({
    id: photoId,
    clientId: 'YOUR-CLIENT-ID-HERE',
    width: 120,
    format: 'webp',
  })

  return <img src={imageUrl} />
}

Done!
