Install packages required for versions below 12

17 Jun 20261 minute to read

For Angular versions below 12, use the legacy (ngcc) package of the Angular components. To download the ngcc package, use the commands below.

Add @syncfusion/ej2-angular-pdfviewer@ngcc to the application:

npm install @syncfusion/ej2-angular-pdfviewer@ngcc --save

To reference the ngcc package in the package.json file, append the -ngcc suffix to the package version:

"@syncfusion/ej2-angular-pdfviewer": "20.2.38-ngcc"

NOTE

If the -ngcc tag is not specified during installation, the Ivy library package will be installed. In View Engine projects this may produce compatibility warnings; use the -ngcc package for Angular versions below 12.
