Hono is a small, simple, and ultrafast web framework for the Edges. It works on Cloudflare Workers, Fastly Compute, Deno, Bun, Vercel, Netlify, AWS Lambda, Lambda@Edge, and Node.js. Fast, but not only fast.

Hi, my program needs to do caching to work. I read upstash documentation and liked it. But I don't understand why it uses Rest API instead of TCP, even though Cloudflare supports it. Also, I'd be glad if you tell me more about caching methods in Cloudflare Workers.

E

Erisa•7/30/24, 9:32 AM

upstash support for workers has been around for much longer than tcp support has been and frankly sending off a fetch is still a lot easier to explain, so they probably never found benefit in providing guides for tcp. it should work just fine though, if you work out how to interact with redis over a raw tcp socket

To use module workers do I need the wrangler.toml file ?

Generates error when creating a Worker via API

Error
"Uncaught SyntaxError: Unexpected token 'export'\n at worker.js:141\n"

New code:

export default {
    async fetch(request, env, ctx) {
        const url = new URL(request.url);

        if (url.pathname === ENDPOINT) {
            handle(request, url);
        }
    }
}

export default {
    async fetch(request, env, ctx) {
        const url = new URL(request.url);

        if (url.pathname === ENDPOINT) {
            handle(request, url);
        }
    }
}

export default {
    async fetch(request, env, ctx) {
        const url = new URL(request.url);

        if (url.pathname === ENDPOINT) {
            handle(request, url);
        }
    }
}

export default {
    async fetch(request, env, ctx) {
        const url = new URL(request.url);

        if (url.pathname === ENDPOINT) {
            handle(request, url);
        }
    }
}

It worked with:

addEventListener("fetch", event => {
    const url = new URL(event.request.url);

    if (url.pathname === ENDPOINT) {
        event.respondWith(handle(event, url));
    }
});

addEventListener("fetch", event => {
    const url = new URL(event.request.url);

    if (url.pathname === ENDPOINT) {
        event.respondWith(handle(event, url));
    }
});

addEventListener("fetch", event => {
    const url = new URL(event.request.url);

    if (url.pathname === ENDPOINT) {
        event.respondWith(handle(event, url));
    }
});

addEventListener("fetch", event => {
    const url = new URL(event.request.url);

    if (url.pathname === ENDPOINT) {
        event.respondWith(handle(event, url));
    }
});

if not I could look into making these requests from a VPS with a fixed IP instead
