file

(plugins.file)

Overview

The file management plugin offers a comprehensive toolkit for managing files and folders both locally and remotely. It supports operations such as creating, reading, modifying, and deleting files while accommodating various formats, including text, binary, and XML. Advanced features like encoding, content streaming, and size management are also integrated to enhance file interactions on both the client and server sides.

Users can perform essential tasks such as appendToTXTFile, writeFile, and writeXMLFile, which allow appending, creating, or modifying files efficiently. The plugin also supports creating temporary files through createTempFile and managing folder contents with getFolderContents. Folder operations include recursive copying using copyFolder and deletion with deleteFolder, all while providing detailed file attributes such as modification dates via getModificationDate and sizes with getFileSize. Flexible filtering options enable targeted retrieval of folder contents, enhancing workflow precision.

For interactive use, the plugin facilitates file selection dialogs through showFileOpenDialog, supporting multiselect and file type filters, with customizable callback functionality. Large files can be streamed directly to the browser using streamFile without consuming excessive memory, ensuring optimal performance for downloads or inline viewing. Temporary file handling via trackFileForDeletion automates cleanup processes upon solution closure, contributing to resource efficiency.

showFileOpenDialog(selectionMode, startDirectory, multiselect, filter, callbackfunction)

Shows a file open dialog. Filters can be applied on what type of files can be selected. (Web Enabled, you must set the callback method for this to work)

Parameters

  • Number selectionMode 0=both,1=Files,2=Dirs

  • JSFile startDirectory JSFile instance of default folder,null=default/previous

  • Boolean multiselect true/false

  • Object filter A filter or array of filters on the folder files.

  • Function callbackfunction A function that takes the (JSFile) array of the selected files as first argument

Returns: Object

Sample

// This selects only files ('1'), previous dir must be used ('null'), no multiselect ('false') and
// the filter "JPG and GIF" should be used: ('new Array("JPG and GIF","jpg","gif")').
/** @type {JSFile} */
var f = plugins.file.showFileOpenDialog(1, null, false, new Array("JPG and GIF", "jpg", "gif"));
application.output('File: ' + f.getName());
application.output('is dir: ' + f.isDirectory());
application.output('is file: ' + f.isFile());
application.output('path: ' + f.getAbsolutePath());

// This allows mutliple selection of files, using previous dir and the same filter as above. This also casts the result to the JSFile type using JSDoc.
// if filters are specified, "all file" filter will not show up unless "*" filter is present
/** @type {JSFile[]} */
var files = plugins.file.showFileOpenDialog(1, null, true, new Array("JPG and GIF", "jpg", "gif", "*"));
for (var i = 0; i < files.length; i++)
{
	 application.output('File: ' + files[i].getName());
	 application.output('content type: ' + files[i].getContentType());
	 application.output('last modified: ' + files[i].lastModified());
	 application.output('size: ' + files[i].size());
}
//for the web and NG you have to give a callback function that has a JSFile array as its first argument (also works in smart), only multi select and the title are used in the webclient, others are ignored
plugins.file.showFileOpenDialog(null,null,false,new Array("JPG and GIF", "jpg", "gif"),mycallbackfunction,'Select some nice files')

When handling big files please look at the admin page properties: "servoy.ng_web_client.tempfile.threshold" and "servoy.ng_web_client.temp.uploadir", so that big files are mapped to temp files and saved to a good temp dir
so that in the callback method you can try to rename the temp generated file to something on the filesystem with a specific name. This way there is no need to stream anything again on the server side
(or access the bytes which will load the big file completely in memory)

//for the web and NG you have to give a callback function that has a JSFile array as its first argument (also works in smart), only multi select and the title are used in the webclient, others are ignored
plugins.file.showFileOpenDialog(null,null,false,new Array("JPG and GIF", "jpg", "gif"),mycallbackfunction,'Select some nice files')

When handling big files please look at the admin page properties: "servoy.ng_web_client.tempfile.threshold" and "servoy.ng_web_client.temp.uploadir", so that big files are mapped to temp files and saved to a good temp dir
so that in the callback method you can try to rename the temp generated file to something on the filesystem with a specific name. This way there is no need to stream anything again on the server side
(or access the bytes which will load the big file completely in memory)

streamFile(file)

Stream the given file(path) to the browser with content-disposition:attachment This will not load in the file fully into memory but only stream it right from disk. This can be any filepath on the server, but only the simple file name is exposed as the content disposition header filename. This will throw an exception if anything goes wrong, like the given file is not valid/found.

Parameters

  • Object file A path string, JSFile or RemoteFile

Returns: void

streamFile(file, contentDisposition)

String the given file(path) to the browser you can provide the content disposition how this should be send (inline or as an attachment) This will not load in the file fully into memory but only stream it right from disk. This can be any filepath on the server, but only the simple file name is exposed. This will throw an exception if anything goes wrong, like the given file is not valid/found.

Parameters

  • Object file A path string, JSFile or RemoteFile

  • String contentDisposition can be 'inline' or 'attachment'

Returns: void

streamFile(file, contentDisposition, browserTarget)

String the given file(path) to the browser you can provide the content disposition how this should be send (inline or as an attachment) This will not load in the file fully into memory but only stream it right from disk. This can be any filepath on the server, but only the simple file name is exposed. This will throw an exception if anything goes wrong, like the given file is not valid/found. Give the browser target if you want to open the file inside another tab, most usefull in 'inline' content disposition mode.

Parameters

  • Object file A path string, JSFile or RemoteFile

  • String contentDisposition can be 'inline' or 'attachment'

  • String browserTarget _blank or a specific name to open this in a differnt tab (really only usefull in inline mode)

Returns: void

trackFileForDeletion(file)

If the client's solution is closed, the file given to this method will be deleted. This can be a remote or local file.

This can be used to have temp files within a client that will be cleaned up when the solution is closed. So they live as long as the client has its solution open.

Parameters

Returns: void

Sample

var file = plugins.file.createFile("newfile.txt");
plugins.file.writeTXTFile(file, "some data");
plugins.file.trackFileForDeletionfile(file);

writeFile(file, data)

Writes the given file to disk.

If "file" is a JSFile or you are running in Smart Client, it writes data into a (local) binary file.

If you are running in Web Client and "file" is a String (like 'mypdffile.pdf' to hint the browser what it is) the user will get prompted by the browser to save the file (sent using "Content-disposition: attachment" HTTP header). If it is a JSFile instance in this case it will be saved as a file on the server.

Parameters

  • JSFile file a local JSFile

  • Array data the data to be written

Returns: Boolean

Sample

/**@type {Array<byte>}*/
var bytes = new Array();
for (var i=0; i<1024; i++)
	bytes[i] = i % 100;
var f = plugins.file.convertToJSFile('bin.dat');
if (!plugins.file.writeFile(f, bytes))
	application.output('Failed to write the file.');
// mimeType variable can be left null, and is used for webclient only. Specify one of any valid mime types as referenced here: https://developer.mozilla.org/en-US/docs/Properly_Configuring_Server_MIME_Types
var mimeType = 'application/vnd.ms-excel'
if (!plugins.file.writeFile(f, bytes, mimeType))
	application.output('Failed to write the file.');

writeFile(file, data, mimeType)

Writes the given file to disk.

If "file" is a JSFile or you are running in Smart Client, it writes data into a (local) binary file.

If you are running in Web Client and "file" is a String (like 'mypdffile.pdf' to hint the browser what it is) the user will get prompted by the browser to save the file (sent using "Content-disposition: attachment" HTTP header). If it is a JSFile instance in this case it will be saved as a file on the server.
