This folder contains examples created to illustrate some of the possibilities.
Yes it is possible to create Gantt-Charts, i.e., SVG files (and also convert these to, e.g., PNG) within nodeJS (see here). I personally only use the library within a browser, so the example just shows what may be possible. The examples utilizes phantomJs to render the SVG in the headless browser, retrieves the created SVG and stores it in a file. There are some things to be considered to make this example more usable:
- It may be nicer to push the options, as well as the width and height through nodeJs into the JavaScript. Currently the options are also defined in the JavaScript part. The main reason is that the js-gantt library only supports Date instances out of the box. The options coming from nodeJs are stringified (using JSON), which does not support Date types.
- The rendering of the SVG may take some milliseconds (or seconds if large external sources are used). The js-gantt chart provides events to know when the rendering is finished. Nevertheless, in the example the script just waits a couple of seconds. In a nicer version, nodeJs would utilize the events provided by the library.
To test the example, simply check out the examples folder. Change to
exportSvgWithNodeJs and run npm install (just once to get the dependencies)
and afterwards npm start. After the script is executed, there should be
a ouput folder, which contains a sample.svg.
