HTML DIR CONTENT

(recursively) iterate directory entries in the browser (html5 File System API)

API

• getFiles(item:DataTransferItem, options?: Options) : Promise<Array>

  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

• getFilesFromDragEvent(evt: DragEvent, 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

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

Example

your HTML:

        <script src="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);
                    });
            });

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
