Atob is not defined

[Kirill Mironov]

When using angular-prerender with angular 9 application, it crashes on

.../node_modules/zone.js/dist/zone-node.js:192
throw error;

ReferenceError: atob is not defined

Hi Kirill, is it possible that you're using atob somewhere in your Angular app or that it's used by one of your dependencies? atob and btoa are not available in Node.js.

[Kirill Mironov]

Yes, I do indeed use atob in one route, but it seems like my options here are limited to excluding a route, right?

[Christoph Guttandin]

You could create a little helper which uses the API of the current platform.

import { PLATFORM_ID } from '@angular/core';
import { isPlatformBrowser } from '@angular/common';

export class Base64Service {

    constructor(private @Inject(PLATFORM_ID) platformId: Object) { }

    public atob(value: string): string {
        return isPlatformBrowser(platformId)
            ? atob(value)
            : Buffer.from(value).toString('base64');
    }

}

Or you replace the corresponding service, component, ... by using the DI of the AppServerModule.
