Duplicate toastr error messages

Question

I am using the Toastr 2.1 JavaScript library to display transient user input validation error messages. I set preventDuplicates option to true. It is not working -- I still see duplicate messages when users click validate button in rapid succession (clicks are faster than 'timeout').

Here are my toastr defaults:

function getDefaults() {
    return {
        tapToDismiss: true,
        toastClass: 'toast',
        containerId: 'toast-container',
        debug: false,

        showMethod: 'fadeIn', //fadeIn, slideDown, and show are built into jQuery
        showDuration: 300,
        showEasing: 'swing', //swing and linear are built into jQuery
        onShown: undefined,
        hideMethod: 'fadeOut',
        hideDuration: 1000,
        hideEasing: 'swing',
        onHidden: undefined,

        extendedTimeOut: 1000,
        iconClasses: {
            error: 'toast-error',
            info: 'toast-info',
            success: 'toast-success',
            warning: 'toast-warning'
        },
        iconClass: 'toast-info',
        positionClass: 'toast-top-right',
        timeOut: 5000, // Set timeOut and extendedTimeOut to 0 to make it sticky
        titleClass: 'toast-title',
        messageClass: 'toast-message',
        target: 'body',
        closeHtml: '<button>&times;</button>',
        newestOnTop: true,
        preventDuplicates: true,
        progressBar: false
    };
}

Do i need to make any other changes to prevent duplicate error messages?

Answer 1

imports: [
  ToastrModule.forRoot({
    timeOut: 10000,
    positionClass: 'toast-bottom-right',
    preventDuplicates: true,
  }),
],

this is also present in npm for ngx-toastr documentation. you can add it in your app module.ts to see the change.
