Lazy routers?

Hi, does hono support lazy routers? I made a really huge router with some heavy dependencies and now I'm getting spikes on cold starts

Not out of the box, but maybe you can try async imports within a “router of routers”.

I don't quite get the idea

.get("/some-route", async (c) => {
  if (!someRouteCode) {
    someRouteCode = await import("./some-route-code")
  }

  return someRouteCode(c)
})

.get("/some-route", async (c) => {
  if (!someRouteCode) {
    someRouteCode = await import("./some-route-code")
  }

  return someRouteCode(c)
})

Something like this?

Yes, I was thinking of request() https://hono.dev/docs/api/hono#request

To be honest, I don't get how is this method usefull in this context May be I'm missing something?

Hono technically supports any kind of router, since you can provide a custom implementation for a router But I don't know if making a lazy router is a great idea

Agree. Cold starts implies lambdalith -- it's probably better handled at the l7 layer (load balancer, api gw, cdn, etc).

@Gary, el Pingüino Artefacto just in case, have you tried using hono/quick? https://hono.dev/docs/api/presets#hono-quick

I'm only know the basic of hono, so no. I'm very new. I'll give it a shoot. Thanks dude!
