How do I implement ReCaptcha in a Single Page Application (SPA)
Looks like what I wanted was simply to use reCaptcha without plugins (https://developers.google.com/recaptcha/docs/display)
I have used ngx-captcha with my angular project.Here's how I kept my submit button disabled until recaptcha checkbox is checked.
//code <ngx-recaptcha2 (success)="handleSuccess($event)" #captchaElem [siteKey]="siteKey" formControlName="recaptcha"> </ngx-recaptcha2>once captcha is filled , it emits a success event , so use it in a method to make a variable true/false based on which you can enable/disable submit button
