filelist-utils

Create a FileCollection from various sources.

Introduction

In order to make compatible code between the browser and node and to allow drag and drop of a folder it is useful to an abstraction level.

This package allows to create a FileCollection from various sources:

a FileList (that implements an Iterator of File).
a relative path (with its basedir)
a webservice that returns a JSON containing an array of object that has the following properties: relativePath, name, lastModified, size

A FileCollection has an iterator on FileCollectionItem that has the following properties:

lastModified: number;
name: string;
relativePath: string;
size: number;
arrayBuffer(): Promise;
stream(): ReadableStream;
text(): Promise;

Load and Save from remote server

// You should have a webservice that returns this kind of object

const source = {
  files: [
    {
      name: 'data.zip',
      size: 1589,
      relativePath: 'dataUnzip/data.zip',
      lastModified: 1664430693588,
    },
    {
      name: 'a.txt',
      size: 1,
      relativePath: 'dataUnzip/dir1/a.txt',
      lastModified: 1664430693588,
    },
  ],
  baseURL: 'http://localhost/',
};
const fileCollection = fileCollectionFromSource(source);
