flask-replit-auth

The Unofficial Replit Auth Flask Extension

Replit authentication is an amazing thing. This package provides an easy way to use it.

from flask_replit_auth import replit_auth
from flask import request, Flask

app = Flask(__name__)
replit_auth(app)

@app.route("/")
def index():
  if request.user:
    return request.user['username']
  else:
    return 'Not logged in!'

if __name__ == "__main__":
  app.run(host='0.0.0.0')

Initialize replit auth on your app by calling replit_auth(app), after creating your flask app. To get information, call request.user, which will either return None or a dict with the information.

Replit Auth - Frontend

var button = document.getElementById('login_with_replit');

if (location.protocol !== 'https:') {
  alert('Replit auth requires https!');
}

button.onclick = function() {
  window.addEventListener('message', authComplete);

  var h = 500;
  var w = 350;
  var left = (screen.width / 2) - ( w / 2);
  var top = (screen.height / 2) - (h / 2);

  var authWindow = window.open('https://replit.com/auth_with_repl_site?domain=' + location.host, '_blank', 'modal=yes, toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=no, resizable=no, copyhistory=no, width=' + w + ', height=' + h + ', top=' + top + ', left=' + left)

  function authComplete(e) {
    if (e.data !== 'auth_complete') {
      return;
    }

    window.removeEventListener('message', authComplete);

    authWindow.close();

    // Reload the page to get the credentials.
    location.reload();
  }
}
