Cloudflare Durable Objects
By using Hono, you can write Durable Objects application easily.
Hono can handle a fetch event of Durable Objects and you can use it with the powerful router.
ts
import { Hono } from 'hono'
export class Counter {
value: number = 0
state: DurableObjectState
app: Hono = new Hono()
constructor(state: DurableObjectState) {
this.state = state
this.state.blockConcurrencyWhile(async () => {
const stored = await this.state.storage?.get<number>('value')
this.value = stored || 0
})
this.app.get('/increment', async (c) => {
const currentValue = ++this.value
await this.state.storage?.put('value', this.value)
return c.text(currentValue.toString())
})
this.app.get('/decrement', async (c) => {
const currentValue = --this.value
await this.state.storage?.put('value', this.value)
return c.text(currentValue.toString())
})
this.app.get('/', async (c) => {
return c.text(this.value.toString())
})
}
async fetch(request: Request) {
return this.app.fetch(request)
}
}
