I'm looking into SuperTokens for an app I coded using Hono on Node (https://hono.dev/). I see that it's not one of the frameworks that currently have a middleware (like Express or Fastify).

I saw in the codebase that there is also a directory for a "custom" framework but couldn't find any documentation on how it's supposed to be used.

Would it be a good way to integrate with Hono or should code the middleware for Hono taking the one from Express as example ? Would it be an interesting contribution ?

hey <@1044012556823568384> you can take inspiration from our remix integration on how to add a custom framework. You can generate a remix app using `npx create-supertokens-app@latest`

In my case I'm using Hono only for API. I understand that in the Remix example, what I should look into are the backend SDK integration in those files:
- config/backend.tsx
- routes/sessioninfos.$.tsx
- routes/supertokens.$.tsx
- superTokensHelpers.ts
- entry.server.tsx

and that the rest would be handled by the  client-side React SDK from SuperTokens.

Am I understanding it right?

yup. So, sessioninfo is not required (thats just an example api). But others, yea.
