Two variables are specified in the input port of variables: Path along which the component will output a list of files, and Boolean WithFolder. By default, the path is set: \user, in order to get a list of files that are in the folder on the demo stand. When running the example locally, you need to specify the path to the folder in the computer's file system.

In the JavaScript node, the output table columns are configured. It will have the following structure:

Name	Capture
Name	Name
FileExtension	FileExtension
FilePath	FilePath
Size	Size
isValidFilePath	isValidFilePath
isFolder	isFolder
mDate	mDate

Code:

import { InputVariables, OutputTable } from "builtIn/Data";
import * as fs from "builtIn/FS"; 

const { isValidFilePath, Name, isFolder, FileExtension, Size, FilePath, mDate } = OutputTable.Columns;

let path = InputVariables.Items.Path.Value || ".";


if (!fs.existsSync(path)) { // Condition under which the path does not exist 
    OutputTable.Append();
    isValidFilePath.Set(InputVariables.Items.Error.Value); // Error output (variable value)
} else {
    try {
        let files = fs.readdirSync(path, { withFileTypes: true }); // Creating a files object that contains information about the files at the specified path
        for (let file of files) { // A loop in which file system objects are processed 
            OutputTable.Append(); 
            let fname = path + "/" + file.name; // Formation of the full file name (along with the path)
            isValidFilePath.Set(true); // Adding a value to the correct_path field
            Name.Set(file.name);
            FilePath.Set(fname);
            let stat = fs.statSync(fname);
            if (file.isDirectory()) { // Checking if an object is a file
                isFolder.Set(true);
            } else {
                let p = file.name.lastIndexOf("."); // Getting the position of a point
                let ext = "";
                if (p > -1) {
                    ext = file.name.substring(p + 1); // Formation of expansion
                }
                FileExtension.Set(ext);
                Size.Set(stat.size);
                isFolder.Set(false);
            }
            FilePath.Set(fname);
            mDate.Set(stat.mtime);
        }
    } catch (e) { // Обработка ошибок
        OutputTable.Append();
        isValidFilePath.Set(e);
    }
}

In the Table into Variables node, errors and script execution exceptions are output to the variables port. If there are no errors, true is output.

The SuperNode has an output port for tables and a port for variables.

Name	Caption
Name	Name
FileExtension	FileExtension
FilePath	FilePath
Size	Size
isFolder	isFolder
mDate	mDate

Variables:

Name	Capture	Description
result	result	true/false
