Export Module for PDF

This export module can export data to PDF, PNG, Excel, and iCal files. It can be installed on any platform as a Node.js application or as a Docker image.

It doesn't include the import/export functionality for the MS Project and Primavera files. If you need such a functionality, you should use the corresponding export module or our online server.

Installation guide

First, you need to download and install Node.js. You can find the installation instructions on their website.

You can download the export module in the Client's Area on the Downloads tab. Check the image below:

After downloading that file, unpack it somewhere, then open the command line and navigate to the folder with the export module. For example:

cd C:\export_module

Then you need to install the modules for the application:

npm install

You can install the components to the computer without graphical interface.

To run on a server with a graphical interface, you can use the following command to start the export module:

npm start

To test how it works, you can open the following URL: http://localhost:3200/test.

Or open the main page and click the Test link: http://localhost:3200.

Using server without graphical interface

If you plan to use the export module on a headless server, you need to install additional components. Here is the command for the Deb-based distros:

apt-get install -y xvfb libgtk2.0-0 libgtk-3-0 libgbm-dev 
libnotify-dev libnss3 libxss1 libasound2 libxtst6 xauth

Here is the command for the RPM-based distros:

yum install -y xorg-x11-server-Xvfb gtk2-devel gtk3-devel 
libnotify-devel GConf2 nss libXScrnSaver alsa-lib

Then you need to run it with another command:

npm run start:docker

or

xvfb-run node index.js

Problem solving

Old Node.js version

The export module is compatible with the node version 12.03 and newer. If you have an older version, you need to install the older version of Electron:

npm install electron@6.1

Export to PDF never ends

If you use Windows with the custom DPI settings or fonts, there is a bug in the Electron component. To make it work, you need to install an earlier version:

npm install electron@6.1

Export to PDF/PNG doesn't work on Mac M1

The Electron version that is currently used, doesn't have builds for the Darwin-ARM64 architecture. As a workaround, you can try installing Electron 11.

npm install electron@11

The basic export functionality should work, but we didn't check whether all features work correctly with that version:

Export to PDF doesn't work

There can be different reasons for that. You need to check the error messages.

If you get one of the following errors:

• Failed to get crash dump id

• Electron crashed!

most likely, it means that the export module is working on a headless server. You will need to install the necessary components to use PDF and PNG export. Or you can build a Docker image.

Using a Docker image

Build the Docker image with the following command:

docker build -t dhtmlx/scheduler-gantt-export ./

Run the Docker image using the command below:

docker run -d -p 3200:80 dhtmlx/scheduler-gantt-export

3200 is the port on which the docker service will work.
