HTML DIR CONTENT

Tiny, dependency-free library to (recursively) iterate directory entries in the browser (html5 File System API)

Install

In Node/Webpack environment:

    npm i html-dir-content
    OR
    yarn add html-dir-content

Directly in the browser:

    <script src="https://unpkg.com/html-dir-content/dist/html-dir-content.min.js"></script>

API

getFiles

getFiles(item:[DataTransferItem](https://developer.mozilla.org/en-US/docs/Web/API/DataTransferItem), options?: Options) : Promise<Array<File>>

Returns a promise of an array of files in case the provided item represents a directory and the FS API returns children files for it.

• Options: Boolean | Object

  (In case of boolean value, it will be used for the recursive config)

  • recursive (default: false) - whether to recursively follow the dir structure
  • bail (default: 1000) - how many levels to follow recursively before bailing
  • withFullPath (default: false) - file names contain the full file path

getFilesFromDragEvent

getFilesFromDragEvent(evt: [DragEvent](https://developer.mozilla.org/en-US/docs/Web/Events/drop), options?: Options)

Returns a promise of an array of files for the given event. In case the event dataTransfer property contains file system entries and at least one of them is represents a directory and the FS API returns children files for it.

• Options: Boolean | Object

  (In case of boolean value, it will be used for the recursive config)

  • recursive (default: false) - whether to recursively follow the dir structure
  • bail (default: 1000) - how many levels to follow recursively before bailing
  • withFullPath (default: false) - file names contain the full file path

note: The order of files returned is not guaranteed to be in same order the files on the file system are organized

note: Firefox will turn any path delimiter (/) in the File name property to ":" (when using 'withFullPath') :( - So in case you need to parse/save the path you can use the custom 'hdcFullPath' prop on the File object or replace the colons with slashes if needed.

Example

check out this codepen.

your HTML:

        <script src="<path-to-node_modules>/html-dir-content/dist/html-dir-content.min.js"></script>

your Javascript:

    window.addEventListener("drop", (e) => {
                e.preventDefault();

                htmlDirContent.getFilesFromDragEvent(e, true) //will perform recusrive traversal
                    .then((files) => {
                        console.log("we have the files: ", files);
                    });
            });

or with import/require:

    import {getFilesFromDragEvent} from "html-dir-content";
    .
    .
    .
    getFilesFromDragEvent(e, true)
        .then((files) => {

        });

You can drag a directory (ex: from File Explorer / Finder) and the resolved files array will contain the files contained within it and its sub folders

Dependencies

Requires global Promise object to be available

Works on Chrome, Firefox, Safari (at least from version 13), and Edge (no support on IE11)
