Workers, Durable Objects - Durable Objects are now supported in Python Workers

You can now create Durable Objects using Python Workers . A Durable Object is a special kind of Cloudflare Worker which uniquely combines compute with storage, enabling stateful long-running applications which run close to your users. For more info see here . You can define a Durable Object in Python in a similar way to JavaScript: from workers import DurableObject , Response , WorkerEntrypoint from urllib . parse import urlparse class MyDurableObject ( DurableObject ): def __init__ ( self , ctx , env ): self . ctx = ctx self . env = env def fetch ( self , request ): result = self . ctx . storage . sql . exec ( "SELECT 'Hello, World!' as greeting" ). one () return Response ( result . greeting ) class Default ( WorkerEntrypoint ): async def fetch ( self , request ): url = urlparse ( request . url ) id = env . MY_DURABLE_OBJECT . idFromName ( url . path ) stub = env . MY_DURABLE_OBJECT . get ( id ) greeting = await stub . fetch ( request . url ) return greeting Define the Durable Object in your Wrangler configuration file: wrangler.jsonc { " durable_objects " : { " bindings " : [ { " name " : "MY_DURABLE_OBJECT" , " class_name " : "MyDurableObject" } ] } } wrangler.toml [[ durable_objects . bindings ]] name = "MY_DURABLE_OBJECT" class_name = "MyDurableObject" Then define the storage backend for your Durable Object: wrangler.jsonc { " migrations " : [ { " tag " : "v1" , // Should be unique for each entry " new_sqlite_classes " : [ // Array of new classes "MyDurableObject" ] } ] } wrangler.toml [[ migrations ]] tag = "v1" new_sqlite_classes = [ "MyDurableObject" ] Then test your new Durable Object locally by running wrangler dev : npx wrangler dev Consult the Durable Objects documentation for more details.
