# Angular project WebViewer integration issues

World's #1 PDF SDK Library for Web, Mobile, Server, Desktop

* The WebViewer does not load properly and the HTML component is recursively re-rendered inside (see image below). How should I fix this?This error has likely occurred because WebViewer can't find it's library. Please make sure that you have done the following:
  * The library containing the `webviewer.min.js` file is not located inside the `PROJ_PATH/src/app/` folder or any of its sub-folders
  * You have correctly added the path to `webviewer.min.js` to the `scripts` array under the `build` options array in `angular.json`
  * You have correctly added the path to the library in the `assets` array under the `build` options in `angular.json`

* WebViewer having issues with progressive web application (PWA)

When using WebViewer as part of a PWA, make sure to include the path to WebViewer "lib" folder in your `ngsw-config.json` file. Also WebViewer needs to pass configuration information to it's workers. Make sure that you are not setting `ignoreSearch` to be `true` under [cacheQueryOptions](https://angular.io/guide/service-worker-config/#cachequeryoptions). So in your `ngsw-config.json` file

{% tabs %}
{% tab title="JSON" %}
{% code lineNumbers="true" %}

```json
"assetGroups": [
  {
    "name": "app",
    "installMode": "prefetch",
    "resources": {
      "files": [
        "/favicon.ico",
        "/index.html",
        "/manifest.webmanifest",
        "/*.css",
        "/*.js",
      ]
    },
    "cacheQueryOptions": {
      "ignoreSearch": true
    }
  },
  {
    "name": "webviewerResources",
    "installMode": "prefetch",
    "resources": {
      "files": [
        "/path to WebViewer lib folder/lib/**"
      ]
    },
    "cacheQueryOptions": {
      "ignoreSearch": false
    }
  },
]
```

{% endcode %}
{% endtab %}
{% endtabs %}

`ignoreSearch` default value is `false` so the `ignoreSearch` above is actually not needed. If a project requires `ignoreSearch` be to `true` for other resources, make sure to not set it to `true` for WebViewer's resources

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.apryse.com/web/get-started/faq/angular-integration-issues.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
