react-firebase-file-upload

Firebase V9 File Upload

Install

npm install --save react-firebase-file-upload

Usage

Full Example

Note Please specify the exact file type you want to accept as shown the example below. Don't use wildcard characters such as image/* in accept parameter. For now, accept parameter will make sure users select ONLY the accepted files if you specified in full. I'm working on validating accept parameter with wildcard characters soon.

import React from 'react'
import { initializeApp } from 'firebase/app'
import { getStorage } from 'firebase/storage'
import { useFileUpload } from 'react-firebase-file-upload'

// TODO: Replace with your app's config object
const firebaseConfig = {
  apiKey: '<your-api-key>',

const firebaseApp = initializeApp(firebaseConfig)

// Get a reference to the storage service, which is used to create references in your storage bucket
const storage = getStorage(firebaseApp)

const App = () => {
  const _input = useFileUpload(storage, {
    // the type of files to upload
    accept: 'image/png, image/jpeg, image/jpg, image/webp',
    // whether to accept multiple files or just one
    multiple: true,
    // where you want to save the uploaded files in firebase storage
    path: `profile-pictures`
