Share and Store CPI Groovy Scripts with Links

Since the online Groovy IDE was very well received by the community, I decided to improve it by enabling sharing and integration. Thank you everyone for comments, giving feedback, and positive vibes!

While I was preparing this post a related productivity improvement feature was added to SAP CPI which enables running parts of flows in simulation. You should definitely check it out!

Use Cases

  • Sharing a message exchange input and Groovy code in a question.
  • Preparing challenges for beginners in a company or preparing tutorials.
  • Sharing very specific solutions for a problem.
  • Send postcards with a Groovy link printed as QR code
  • You can store your favorite templates in browser bookmarks!

How to share

Just click on the share button:

Since I decided not to store anything on the server, a long URL will be copied to the clipboard. It is gzipped which benefits a lot working with XML. You can try it with a reasonably large XML file!

  1. XML file: 460KB (no indentation, one-line input which causes UI problems on most editors)
  2. XML file with indentation: 550KB
  3. Groovy IDE URL for the same input(2): 16KB
  4. My profile picture in this page: 17KB

(I set the server URL limit to 50KB)

Tip: If you are sharing it in a blog post you can hide the long URL like this.

How to integrate

You can trigger Groovy IDE by preparing this URL and opening a new tab:

https://groovyide.com/cpi/share/v1/ + URLSafeBase64(gzip($jsonString))

JSON structure as TypeScript type definition:

interface StateType {
    input: {
        body: string,
        headers: object,
        properties: object
    };
    script: {
        code: string
    };
}

Conclusion

Thanks for your feedback again. If you think about some useful new feature you can write it in the comments or contact me.

      Hi Fatih,

      GroovyIDE is a great tool! Many thanks!

      The following code is working fine in GroovyIDE, but not in CPI DEV tenant.

      import com.sap.gateway.ip.core.customdev.util.Message;
      import java.util.HashMap;
      import groovy.json.*;

      def Message processData(Message message) {
      //Body: JSON file
      def jsonFile = message.getBody();
      def aCandidate = new JsonSlurper().parse(jsonFile);

      //Properties
      def map = message.getProperties();
      def base64PDF = map.get("base64PDF");

      /*
      aCandidate.candidate.resume.file = base64PDF;
      def jsonOut = new JsonBuilder(aCandidate).toPrettyString();
      */

      def builder = new JsonBuilder(aCandidate);
      builder.content.candidate.resume.file = base64PDF; // line 21
      def jsonOut = builder.toPrettyString();

      message.setBody(jsonOut);
      return message;
      }

       

      In CPI DEV tenant, I get the error:

      javax.script.ScriptException: java.lang.Exception: java.lang.NullPointerException: Cannot set property 'file' on null object@ line 21 in script2.groovy, cause: java.lang.NullPointerException: Cannot set property 'file' on null object

      The JSON structure is like this:

      {
      "candidate": {
      "candidate": {
      "contactDetails": {
      "PhoneNumber": "notavailable"
      },
      "email": "john.doe@a.net",
      "firstName": "John",
      "lastName": "Doe"
      },
      "resume": {
      "file": "base64String",
      "fileName": "Profile.pdf"
      }
      }
      }

      What is the root cause of the different behaviour between GroovyIDE and CPI?

       

      Many thanks in advance for your comments!
