Dairi is a web service (that you take care of) that acts as a CORS-bypass proxy thingie for Oshi web app.
It allows the app to make cross-origin requests without being blocked by the browser's same-origin policy.
To set up Dairi with render.com, follow these steps:
-
Sign up for an account on render.com if you haven't already
-
Create a new web service on render.com and choose 'Public Git Repository'

-
Set upp all properties as shown in the image below, and choose your own service name

-
Select the 'Free' tier for 750h of uptime each month, which is just about enough for us (31.25 days)

-
Click 'Deploy Web Service' and grab the URL of the service once it's deployed


-
In the Oshi web app, paste the proxy endpoint address to use your new service

-
Do some testing to ensure that you can now make cross-origin requests
