Referensi Cepat

Array Files

const { files } = useDropup();

// Setiap file memiliki:
files[0].id          // ID unik
files[0].file        // Objek File asli
files[0].name        // Nama file
files[0].size        // Ukuran dalam bytes
files[0].type        // Tipe MIME
files[0].preview     // URL preview (gambar)
files[0].status      // 'idle' | 'uploading' | 'complete' | 'error'
files[0].progress    // 0-100
files[0].uploadedUrl // URL setelah upload
files[0].error       // Error jika gagal

Objek State

const { state } = useDropup();

state.isDragging     // File sedang diseret
state.isDragAccept   // File yang diseret valid
state.isDragReject   // File yang diseret tidak valid
state.isUploading    // Ada file yang sedang diupload
state.progress       // Progres keseluruhan 0-100
state.status         // 'idle' | 'uploading' | 'complete' | 'error'

Objek Actions

const { actions } = useDropup();

actions.upload(fileIds?)     // Mulai upload
actions.cancel(fileId?)      // Batalkan upload
actions.remove(fileId)       // Hapus file
actions.reset()              // Bersihkan semua
actions.retry(fileIds?)      // Coba ulang yang gagal
actions.addFiles(files)      // Tambahkan file secara programatik
actions.updateFileMeta(id, meta)  // Perbarui metadata

Prop Getters

const { getDropProps, getInputProps } = useDropup();

// Terapkan ke zona drop Anda
<div {...getDropProps()}>
  <input {...getInputProps()} />
  Lepas di sini
</div>

// Dengan props kustom
<div {...getDropProps({ className: 'my-dropzone', onClick: handleClick })}>
  ...
</div>

Contoh

Contoh Minimal

function Uploader() {
  const { files, getDropProps, getInputProps } = useDropup();

  return (
    <div {...getDropProps()}>
      <input {...getInputProps()} />
      <p>Lepas file di sini</p>
      <ul>
        {files.map(f => <li key={f.id}>{f.name}</li>)}
      </ul>
    </div>
  );
}

Dengan Upload

function Uploader() {
  const { files, actions, getDropProps, getInputProps } = useDropup({
    upload: {
      url: '/api/upload',

      headers: { 'Authorization': 'Bearer token' },
    },

      <div {...getDropProps()}>
        <input {...getInputProps()} />
        <p>Lepas file di sini</p>
      </div>

      {files.map(f => (
        <div key={f.id}>
          {f.name} - {f.status}
          {f.status === 'uploading' && ` ${f.progress}%`}
        </div>
