Encountering a ReferenceError in Angular 5: require is not defined, alongside a TypeError stating that stream is undefined, following an attempt to import

I am a beginner with Angular(5) and I'm attempting to import a JSON file from the assets folder into a component.
The JSON file contains data for some selections in a form that I want to display in this component.
However, after implementing the following method:

private getJson(url: string, http: HttpClient) {
    if (!url.search("[^]*.json")) {
      throw InvalidPathException;
    } else {
      return http.get(url);
    }
}

and subscribing to it,
I encounter the following errors in my browser:

ReferenceError: require is not defined

TypeError: stream is undefined

Does anyone know how to resolve this issue?

Answer №1

The error in the code was not recognized, but I can suggest an alternative method for handling JSON documents in your Angular5 code using asset files. You can customize the name and content of the JSON file below to suit your needs. Perhaps this approach will be helpful:

In your typescript file:

ngOnInit() {
    this.http.get('assets/json/brandicon.json')
        .toPromise()
        .then(res => res.json().icons)
        .then(brandIcon => this.brandIcon = brandIcon);
}

And in the src\assets\json\brandicon.json file:

{
    "icons": [
        {
            "icon": "fa fa-500px"
        },
        {
            "icon": "fa fa-amazon"
        }
    ]
}
