Every project using PrimeNG needs the locally installed library. You can achieve this by running the following command:
npm install primeng --save
As a result, PrimeNG is installed in your project root under the node_modules folder as well as added in package.json as a dependency. Here again, you can skip this step if you use the seed project hosted on GitHub--just run npm install. The next step is to add two new entries to the SystemJS configuration file. For shorter import statements, it is recommended to map primeng to node_modules/primeng. PrimeNG components are distributed as CommonJS modules ending with .js. That means we should set the default extension too:
System.config({ ... map: { ... 'primeng': ...
