A simple Web App to validate any Email. 🤩

Screen capture of Email Validator Web App.

Email Validator is a Web App that basically validates and verifies any email by providing us with various email properties such as deliverability, quality_score, is_valid_format, is_free_email, is_disposable_email, is_role_email, is_catchall_email, is_mx_found, and is_smtp_valid.

When a user enters any email address and clicks on Verify button, a function httpGetAsync() is called and a XMLHttpRequest() object is created which then sends a GET request asynchronously (in background) with the url consisting of user's unique private API key (provided by Abstarct API) and email-to-be-verified to the Abstract API web server.

Copy and paste the below given function in your .js file and make a call to this function wherever you want to make a request.

function httpGetAsync(url, callback) {
    var xmlHttp = new XMLHttpRequest();
    xmlHttp.onreadystatechange = function() {
        if (xmlHttp.readyState === 4 && xmlHttp.status === 200)
        //Enter your code here...
        callback(xmlHttp.responseText);
    }
    xmlHttp.open("GET", url, true); // true for asynchronous
    xmlHttp.send(null);
}

var url = "https://emailvalidation.abstractapi.com/v1/?api_key=your-private-key&email=email-to-be-verified"

httpGetAsync(url)

Then, the request is processed and a unique JSON response is returned back to the user's end which looks something like the example given below.

{
    "email": "[email protected]",
    "autocorrect": "",
    "deliverability": "DELIVERABLE",
    "quality_score": "0.70",
    "is_valid_format": {
        "value": true,
        "text": "TRUE"
    },
    "is_free_email": {
        "value": true,
        "text": "TRUE"
    },
    "is_disposable_email": {
        "value": false,
        "text": "FALSE"
    },
    "is_role_email": {
        "value": false,
        "text": "FALSE"
    },
    "is_catchall_email": {
        "value": false,
        "text": "FALSE"
    },
    "is_mx_found": {
        "value": true,
        "text": "TRUE"
    },
    "is_smtp_valid": {
        "value": true,
        "text": "TRUE"
    }
}

Now, create a JSON object by parsing the JSON response received from the server by using JSON.parse() method and use the data wherever it is required. This is how this stuff works.
