Improving my solution with PrimeNG in Angular2 - fixing the undefined tag error

After working with Angular for just three days, I successfully set up a login page dashboard using a web API solution. Everything was working great until I encountered an issue when trying to load the PrimeNG DataTableModule into my components. After searching for solutions online, I discovered that the error "Can't bind to 'value' since it isn't a known property of 'p-dataTable'" could be caused by two things: the module not being defined in app.module.ts or the property not existing.

My first question: Why is my app.module.ts split into three separate files (app.module.client.ts, app.module.server.ts, and app.module.shared.ts) in my solution?

My Second Question: When adding the DataTableModule to the app.module.client.ts file, I receive the error mentioned above. However, if I add it to the shared or server module files, a different error occurs stating, "Prerendering failed because of error: ReferenceError: Event is not defined." What am I doing wrong?

Here is the code:

app.module.client.ts

...

app.module.server.ts

...

app.module.shared.ts

...

...

Error message with Module defined in the app.module.client.ts file

Exception: Call to Node module failed with error: Error: Template parse errors: Can't bind to 'value' since it isn't a known property of 'p-dataTable'. 1. If 'p-dataTable' is an Angular component and it has 'value' input, then verify that it is part of this module. 2. If 'p-dataTable' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.

Error message with Module defined in either the app.module.server.ts or app.module.shared.ts file

Exception: Call to Node module failed with error: Prerendering failed because of error: ReferenceError: Event is not defined main-server.js:50676:38)

Answer №1

Did you consider including DataTableModule and SharedModule imports in the sharedConfig NgModule?

I don't have experience with the three separate app.module files, so I can't provide insight on that.

On a side note, PrimeNG recommends avoiding importing all components using statements like:

import {AccordionModule} from 'primeng/primeng';

This may import more components than needed. For more information, refer to their documentation here: https://www.primefaces.org/primeng/#/setup

Answer №2

After encountering an issue with server side prerendering not detecting the dependencies of the toolset, I found a solution by modifying the import modules section in the app.module.shared.ts file. Instead of simply using:

import { DataTableModule, SharedModule } from 'primeng/primeng';

I made the change to:

import { DataTableModule } from 'primeng/components/datatable/datatable';
import { BlockUIModule } from 'primeng/components/blockui/blockui';

This adjustment ensured that the toolset had a full path on the server side, allowing me to continue utilizing prerendering on the server successfully.
