Middleware Implementation Limitation in Hono Routing

[kbventures]

Original conversation: #90 (comment)

Summary:
Issue: The route() method in Hono only accepts a maximum of 2 parameters, making it impossible to explicitly add middleware like authMiddleware within route().

Potential solution:

Middleware array:
https://github.com/honojs/middleware/tree/main/packages/zod-openapi#configure-middleware-for-each-endpoint

Hi @kbventures, would this work as a potential solution (syntactically)?

instead of:

app.use('/*', authMiddleware);
app.route('/profiles', protectedProfileRoutes);
app.route('/teams', protectedTeamRoutes);
app.route('/roles', privateRolesRoutes);

something like this:

const protectedApp = app.use(authMiddleware)
protectedApp.route('/profiles', protectedProfileRoutes);
protectedApp.route('/teams', protectedTeamRoutes);
protectedApp.route('/roles', privateRolesRoutes);

Having like two "top-level" hono apps one that is public and one that is private (private would inherit from the public one with the addition of authMiddleware requiring an auth_token).

Or we can move the authMiddleware into the middleware array of the createRoute function?

As we will have to define all routes using openapi already to document them, I do think we can just try the middleware array and see if it works, if not, then we can think about other approaches.
