Configuration of the javascript library docxtemplater in XPages

Question

I'm trying to use the library docxtemplater in an XPages application.

Javascript library docxtemplater (https://docxtemplater.com/) use as a

dependency another library opensource jszip-utils.js

(http://stuk.github.io/jszip/) to zip and unzip the docx files.

The problem is that the javascript library jszip-utils.js in XPages is not

working .

I inserted javascript libraries in a folder (jslib) who is under the WebContent folder.

Here's my test page;

 <?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="http://www.ibm.com/xsp/core">   

 <script src="jslib/main.min.js"></script>
 <script src="jslib/angular-expressions.js"></script>  
   <script src="jslib/jszip.js"></script> 
   <script src="jslib/jszip-utils.js"></script> 
     <script src="jslib/FileSaver.min.js"></script> 
          <xp:button value="Label" id="button1">
            <xp:eventHandler event="onclick" submit="false">
                <xp:this.script><![CDATA[ 
  var loadFile=function(url,callback){
        JSZipUtils.getBinaryContent(url,callback);
    }

       loadFile("tagExample.docx",function(err,content){
                doc=new DocxGen(content)
                doc.setData( {"first_name":"Hipp",
                    "last_name":"Edgar",
                    "phone":"0652455478",
                    "description":"New Website",
                    "image":'image.png'                 
                    }
                ) //set the templateVariables
                doc.render() //apply them (replace all occurences of {first_name} by Hipp, ...)
                out=doc.getZip().generate({type:"blob"}) //Output the document using Data-URI
                saveAs(out,"output.docx")
            })]]></xp:this.script>
            </xp:eventHandler></xp:button>
          </xp:view>

Has anyone dealt with the problem?

Answer 1

It is an AMD loader issue. It conflicts with XPage's Dojo.

Use this XSnippet for workaround.

Your code would look like this then:

<?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="http://www.ibm.com/xsp/core">

    <xp:this.resources>
        <!-- temporary redefine define.amd object  (Dojo AMD loader) -->
        <xp:script clientSide="true" type="text/javascript">
            <xp:this.contents><![CDATA[${javascript:"if (typeof define === 'function' && define.amd) {if(define.amd.vendor =='dojotoolkit.org'){define._amd = define.amd;delete define.amd;}}";}]]></xp:this.contents>
        </xp:script>

        <xp:script src="jslib/jszip.js" clientSide="true"></xp:script>
        <xp:script src="jslib/jszip-utils.js" clientSide="true"></xp:script>
        ...

        <!-- restore define.amd object (Dojo AMD loader) -->
        <xp:script clientSide="true">
            <xp:this.contents><![CDATA[${javascript:"if (typeof define === 'function' && define._amd) {define.amd = define._amd; delete define._amd;}"}]]></xp:this.contents>
        </xp:script>

    </xp:this.resources>
    ...
