#Bootstrap Alerts

Meteor Package for Bootstrap Alerts. Live example here.

Basics

Alerts.add('Database reading error!'); 

Bootstrap 3.0 contains 4 types of builtin alerts: success, info, warning, danger.

You can easelly add such sort of notifications to your Meteor project by using this package.

Usage

Install package from Atmosphere:

mrt add bootstrap-alerts

Put template string to top of your page:

{{> bootstrapAlerts}}

Display alerts from JavaScript code:

Alerts.add('Database reading error!'); // default type is 'danger'
Alerts.add('Local drive [C:] formatted successfully!', 'success');
Alerts.add('Server recovered from crash.', 'info');
Alerts.add('Please don\'t eat my cake!', 'warning');
Alerts.add('Can\'t remove Admin user!', 'danger');

Customisation

Default options is:

    defaultOptions: {

        /**
         * Button with cross icon to hide (close) alert
         */
        dismissable: true,

        /**
         * CSS classes to be appended on each alert DIV (use space for separator)
         */
        classes: '',

        /**
         * Hide alert after delay in ms or false to infinity
         */
        autoHide: false,

        /**
         * Time in ms before alert fully appears
         */
        fadeIn: 200,

        /**
         * If autoHide enabled then fadeOut is time in ms before alert disappears
         */
        fadeOut: 600,

        alertsLimit : 3
    }

You can override from javaScript code, e.g.:

Alerts.defaultOptions.alertsLimit = 1;

Function Alerts.add

The prototype of Alerts.add function is:

 /**
     * Add an alert
     *
     * @param message (String) Text to display.
     * @param mode (String) One of bootstrap alerts types: 'success', 'info', 'warning', 'danger' (default)
     * @param options (Object) Options if required to override some of default ones.
     *                          See Alerts.defaultOptions for all values.
     */
    add: function (message, mode, options)

The mode and options parameters are optional.

The options parameter provides customization for current alert. Example:

Alerts.add('Can\'t remove Admin user!', 'danger', {
                fadeIn: 1000, fadeOut: 1000, autoHide: 3000
            });

Removing Alerts

In case if you use common template for your application and alerts should be removing after changing a page you should call Alerts.removeSeen() function:

/**
     * Call this function before loading a new page to clear errors from previous page
     * Best way is using Router filtering feature to call this function
     */
    removeSeen: function ()

This is example of iron-router before hook:

Router.before(function () { Alerts.removeSeen(); });
