If you're looking to do anything that big, Rust might be that way to go (even just for performance sake, you might hit the execution time ceiling quickly with JS)

The example takes about 20ms, and the project I'm using it with (the minecraft inventory, opacity blending, color blending, etc), takes about ~30-40ms

not a ton of headroom

Yeah, I'm looking to add generated social images to my site soon. Probably going to go with rust, but if you had just happened to stumble across an easy JS one, I might have gone that route. Thanks for sharing the write up—it's really very very cool

I'll definitely keep my eyes open. Thanks!

That'd interesting to see! I'm very tempted myself... 500+ pages of social images and text doesn't sound fun doing by hand ahah

Good evening 🙂 Are functions mapped to workers? I want to deploy an Apollo GQL server using functions, but I'm not sure how to go about this. https://github.com/cloudflare/workers-graphql-server

@mike.pete I don’t know about functions. You can deploy this on workers. I’ve done it. We have a lot of Apollo experience.

Replies should ping automatically.

Thanks Gary 🙂

Functions aren’t a 1-to-1, but you can probably deploy it in advanced mode with a _worker.js file

Are you doing a monolith Apollo GraphQL Server?

That sounds promising, are there docs on this anywhere?

I was hoping to keep everything in Pages (mostly for ease of deployment) but I'm still pretty new to Cloudflare and GQL in general.

https://developers.cloudflare.com/pages/platform/functions#advanced-mode for how to deploy _workers.js files, but no specific tutorial for GraphQL.

Also tbh, I'm not entirely sure what you mean by

monolith Apollo GraphQL Server

Awesome, I'll check it out! Thank you!

No problem, happy to help!

would someone be willing to try the https://blog.cloudflare.com/introducing-the-workers-cache-api-giving-you-control-over-how-your-content-is-cached/ example on pages?

thanks to Greg, I was able to get my stuff to compile, but I'm getting "undefined" from

cache.match()

on local, and 1101 errors on prod

I'm gonna try to dig and get more info when I can, but this feels wack

Can you post your latest version of the code?

Definitely should be possible! Either with a file in your

functions

directory, or with the

_worker.js

as mentioned below. I’d personally only go with

_worker.js

if you’ve got a custom build process that you need.

That's good to know, thanks Greg!

Right now I'm just using the boilerplate from the blog post, minus this bit:

js
let hash = await sha256(body)

let url = new URL(request.url)
url.pathname = "/posts" + url.pathname + hash

Is the hashing part required?

I'll post more when I'm back from work

sorry for the goose chase, I appreciate the help 🙏

this is my exact GET function:

ts
export const onRequestGet: PagesFunction<{}> = async ({ request, env }): Promise<Response> => {
    const doc = "getKits";
    const subject = "MJ00Y";
    cache = cache || await caches.open('kits');

    const cacheKey = new Request(request.url, {
        headers: request.headers,
        method: 'GET'
    });

    const cached = await cache.match(request);

    if (cached) {
        const cloned = cached.clone();
        cloned.headers.set('cf-cache-status', 'HIT');
        return cloned;
    }

    let real = GetMongoDocument(env, collectionName, { _id: query(subject!) }).then(async (res) => {
        const response = toJSON(res);
        cache.put(cacheKey, response.clone());
        response.headers.set('cf-cache-status', 'MISS');
        return response;
    }).catch((err) => {
        return toError(Errors.ERR_INTERNAL_ERROR, doc, err);
    });

    return real;
};

I fixed the 1000 error (whoops). I'm getting "MISS" on each request

You probably need to

waitUntil

the

cache.put

to ensure it actually runs, since it returns a promise. It’s available like request and env with functions.
