Function: createFileArray()

createFileArray(files): File[]

Defined in: file-array.ts:27

Converts a single File or FileList to an array of File objects.

This utility function normalizes the output of file inputs, making it easier to work with file data in a consistent way regardless of whether the input accepts single or multiple files.

Parameters

files

A single File object or a FileList from an input element

File | FileList

Returns

File[]

An array containing the File object(s)

Example

// Handle file input change event
const input = document.querySelector('input[type="file"]') as HTMLInputElement;
input.addEventListener('change', (event) => {
  const files = createFileArray(input.files!);
  files.forEach(file => {
    console.log(`File: ${file.name}, Size: ${file.size} bytes`);
  });
});

// Works with both single and multiple file inputs
const singleFile = new File(['content'], 'test.txt');
const fileArray = createFileArray(singleFile); // [File]
