Quick start

import { getStorage } from "firebase/storage";
import { StorageManager } from "firebase-storage-kit";

const storage = getStorage(app);
const manager = new StorageManager(storage);

const handle = manager.uploadFile(file, {
  path: `uploads/${file.name}`,
  validate: {
    maxSizeBytes: 10 * 1024 * 1024,
    allowedMimeTypes: ["image/jpeg", "image/png", "image/webp"],
    allowedExtensions: [".jpg", ".jpeg", ".png", ".webp"],
  },
  retry: { maxRetries: 3 },
});

handle.on("progress", (upload) => {
  console.log(upload.progress);
});

handle.on("retry", ({ attempt, maxAttempts, delayMs }) => {
  console.log(`Retry ${attempt}/${maxAttempts} in ${delayMs}ms`);
});

handle.on("success", (upload) => {
  console.log(upload.downloadURL);
});

handle.on("error", (upload) => {
  if (upload.error?.name === "ValidationError") {
    console.error("Invalid file:", upload.error.message);
    return;
  }
  console.error("Upload failed:", upload.error?.message);
});

React

import { useStorageManager, useUpload } from "firebase-storage-kit/react";

const manager = useStorageManager(storage);
const handle = manager.uploadFile(file, {
  path: `uploads/${file.name}`,
  validate: {
    maxSizeBytes: 10 * 1024 * 1024,
    allowedMimeTypes: ["image/jpeg", "image/png", "image/webp"],
    allowedExtensions: [".jpg", ".jpeg", ".png", ".webp"],
  },
  retry: { maxRetries: 3 },
});
const upload = useUpload(handle);
