what about hostnames for example mystore.com is a frontend calling api.mysaasapi.com that's my worker domain (and in mysaasapi WAF I blocked all hostname not equal mystore.com) . what you think can people modify the hostname with api calling.

Hello, I’m Allie!OP•2/10/24, 8:14 AM

That would block all requests, since a request to api.mysaasapi.com would always have a hostname value of api.mysaasapi.com

Hello, I’m Allie!OP•2/10/24, 12:11 PM

In terms of raw query speed(for key value stuff), probably. But again, speed from Worker to response is all about where it spawns

H

Hello, I’m Allie!OP•2/10/24, 12:12 PM

As for the state, I would recommend using the Transactional Storage API, as In-Memory state is not guaranteed to persist between requests

Unable to access KV value from a TypeScript.

I have been spinning my wheels on this for a couple of days. I have a Worker (Auth) running Typescript and I reference a linked module.

import { GetGuid, CheckAuth } from '../../util/Util';

import { GetGuid, CheckAuth } from '../../util/Util';

import { GetGuid, CheckAuth } from '../../util/Util';

import { GetGuid, CheckAuth } from '../../util/Util';

When I call CheckAuth (and pass in the "env" variable, I can see the KV Namespaces, but when I attempt to get a value from the namespace, it just fails silently and moves on.

export async function CheckAuth(env, walletID){
    console.log(walletID)
    console.log(env.SESSION.get)
    try{
        const sid = await env.SESSION.get(walletID)
        console.log(sid)
    }
    catch(ex){
        console.log(ex)
    }
    console.log("SID")
}

export async function CheckAuth(env, walletID){
    console.log(walletID)
    console.log(env.SESSION.get)
    try{
        const sid = await env.SESSION.get(walletID)
        console.log(sid)
    }
    catch(ex){
        console.log(ex)
    }
    console.log("SID")
}

export async function CheckAuth(env, walletID){
    console.log(walletID)
    console.log(env.SESSION.get)
    try{
        const sid = await env.SESSION.get(walletID)
        console.log(sid)
    }
    catch(ex){
        console.log(ex)
    }
    console.log("SID")
}

export async function CheckAuth(env, walletID){
    console.log(walletID)
    console.log(env.SESSION.get)
    try{
        const sid = await env.SESSION.get(walletID)
        console.log(sid)
    }
    catch(ex){
        console.log(ex)
    }
    console.log("SID")
}
