Customizing JavaScript Source Code¶

The JavaScript source code is customized to improve performance.

To customize the JavaScript source code

1. Create a working directory where you can extract sources from the JasperReports Server source bundle Zip file (TIB_js-jrs_<version>_src.zip).
2. Download and install node.js from http://nodejs.org/.
3. Install yarn (version 1.22.x is required).

4. Run the following commands to install node modules.

5. cd jasperserver-ui/pro

   • yarn install

     1. Make your changes to the JavaScript source code.
     2. Run the following commands to build the final bundled static assets.

   • cd jasperserver-ui/pro/jrs-ui-pro

   • yarn run clean

   • yarn run build
     Bundled static assets will be placed in the jrs-ui/build/overlay/scripts folder.

6. Back up the scripts folder of your JasperReports Server instance deployment.
   For example, <tomcat>/webapps/jasperserver-pro/scripts folder, when Apache Tomcat is used.

7. Delete the content of the scripts folder of your JasperReports Server instance deployment.
   For example, <tomcat>/webapps/jasperserver-pro/scripts folder.
8. To deploy bundled static assets (build result) to the JasperReports Server instance, copy the content of the jrs-ui-pro/build/overlay/scripts folder to the scripts folder of your JasperReports Server instance deployment.
   For example, <tomcat>/webapps/jasperserver-pro/scripts folder.
