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.

•

cd jasperserver-ui/pro

•

yarn install

5.

Make your changes to the JavaScript source code.

6.

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.

7.

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

8.

Delete the content of the scripts folder of your JasperReports Server instance deployment. For example, <tomcat>/webapps/jasperserver-pro/scripts folder.

9.

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.

Visualize.js will be built as part of the build process of JavaScript source code. Therefore, there is no separate build process for Visualize.js while starting JasperReports Server 9.0.0.
