Is there a way to access Instagram using Javascript for login?

Goal

I am determined to automate the Instagram login process using Javascript by filling in the username and password fields, then clicking the log in button.

My Attempts (with correct credentials):

Access Instagram Login Page

document.querySelector('[name=username]').value = "USERNAME";
document.querySelector('[name=password]').value = "PASSWORD";

var buttons = document.getElementsByTagName('button');
for (var i = 0; i < buttons.length; i++) {
    if (buttons[i].innerText == 'Log in') {
        buttons[i].click();
        break;
    }
}

Issue:

Despite inputting the correct username and password, an error message is displayed:

The username you entered doesn't belong to an account. Please check your username and try again.

Inquiry

Can Instagram login be automated using Javascript? If so, what is the correct approach?

Answer №1

The main issue stems from Instagram's use of React, where the UI is constructed with "component" objects that update the DOM based on their state changes. When the text field value is modified directly in the DOM, the component states are not updated accordingly, causing Instagram's React code to remain unaware of the new value. Consequently, when you click the button, the login request contains the original (empty) value.

To successfully achieve this, a workaround would involve finding a method to prompt React into updating the component state. Perhaps experimenting with triggering a synthetic event on an element could deceive React into believing that user input has occurred. However, as I'm not well-versed in React intricacies, my assistance is limited beyond this suggestion.
