Ajax Toast Interceptor

Intercepts AJAX / XMLHttpRequest responses from your back-end and displays relevant 'toast' notifications, so you can focus on the useful code :)

Why?

Because displaying javascript notifications to your visitors is a repetitive task that needn't be. Simply format your back-end response the right way, and this package will display the notification to your visitors.

Installation

npm install ajax-toast-interceptor --save

Usage

Simply return a correctly formatted JSON response from your API to have messages displayed in the client's browser via iziToast.

axios integration

axios
    .post('/save-user-profile', { firstName: 'John', lastName: 'Doe' })
    .then(function(response) {
        // Success notification handled by ajax toast interceptor
        // Your code goes here
        console.log(response);
    })
    .catch(function(error) {
        // Error notification handled by ajax toast interceptor
        // Your code goes here
        console.log(error);
    });

jQuery integration

$.ajax({
    url: '/save-user-profile',
    method: post,
    data: { name: 'John', location: 'Doe' },
})
    .done(function(response) {
        // Success notification handled by ajax toast interceptor
        // Your code goes here
        console.log(response);
    })
    .fail(function(error) {
        // Error notification handled by ajax toast interceptor
        // Your code goes here
        console.log(error);
    });

Sometimes you only need a notification message (error or success) without any other actions. In that case you can skip the done and fail callbacks altogether:

axios.post('/save-user-profile', { firstName: 'John', lastName: 'Doe' });

$.ajax({
    url: '/save-user-profile',
    method: post,
    data: { name: 'John', location: 'Doe' },
});

Success (HTTP response codes 200 -> 399) :

Example of success response received from the back-end:

{
    "flash": true,
    "title": "Success",
    "message": "The action was successful",
    "callback": "reload"
}

flash must be set to true and message must be present for the toast notification to be displayed.

Error (HTTP response codes 400+) :

Example of error response received from the back-end:

{
    "flash": true,
    "message": "Something went wrong"
}

flash can be set to false to disable error notifications. Also displays classic HTTP errors (404, 500...).

Validation errors (HTTP response code 422) :

Example of validation error response received from the back-end:

{
    "flash": true,
    "message": "Validation failed for the following fields:",
    "errors": ["Name field is required", "Email field is invalid"]
}
