Storing Data

A common pattern in SaaS apps is to give each customer a unique subdomain. By default second-level domains are considered internal to your application. (For more info see Defining Internal URLs below)
Say you have your customers login at https://login.yourapp.com which then redirects them to https://yourcustomer.yourapp.com. You can store the last used subdomain and redirect your users there when they open the app.
// On login to subdomain https://yourcustomer.yourapp.com
if (window.todesktop) {
localStorage.setItem('subdomain', 'yourcustomer');
}
​
// When not already on subdomain then redirect to last used subdomain
if (window.todesktop) {
const subdomain = localStorage.getItem('subdomain')
​
if (subdomain) {
window.location = `https://${subdomain}.yourapp.com`
}
}
​
We recommend having a separate javascript app for all of your ToDesktop specific login and importing that conditionally when your app is running as a desktop app.
