Cloudflare Durable Objects

Durable Objects provide strongly consistent, single-threaded state for each agent.

Core Pattern: Agent as Durable Object

import { DurableObject } from 'cloudflare:workers'

export class AgentDO extends DurableObject {
  private initialized = false
  
  constructor(ctx: DurableObjectState, env: Env) {
    super(ctx, env)
  }
  
  async fetch(request: Request): Promise<Response> {
    // Lazy initialization
    if (!this.initialized) {
      await .()
    }
    
    
     (request..() === ) {
       .(request)
    }
    
    
     url =  (request.)
     (url.) {
       :
         .(request)
       :
         .(request)
      :
          (, { :  })
    }
  }
  
    () {
    
    . = 
  }
}
