You could use ?

Though if your concern is people publishing the worker, miniflare doesn't do that

That's wrangler

I may just be really tired today, but wasn't miniflare able to run typescript locally without a build step? May have been dreaming too.

I don't believe so?

I ran into another thing that miniflare does not fail on but real workers do fail:

js
const myBlob = await response.blob();

await env.BUCKET.put(blobId, myBlob); // must use myBlob.stream()

Can you file this in the Miniflare repo? https://github.com/cloudflare/miniflare/issues/new

done

Is it possible to somehow enable support for

eval

in miniflare?

Or should I just use the debugging facilities to experiment with that kind of thing (run code in debugger console)

I tried running

wrangler pages dev

(v3) locally with

--local-protocol=https

and I got a warning saying that miniflare 3 doesn't support https servers yet, so it started an http server instead. I was hoping to test a 3rd party API locally that requires requests be made over https, which is why I tried using

--local-protocol=https

. Any idea when this will be added?

I don't know of an ETA for them adding that, but in the meantime you could use a Cloudflare Tunnel to send requests directly to your machine?

I'll have to give that a try

Hey! 👋 This isn't possible right now unfortunately. What's your use case?

I wanted to build myself something akin to a hybrid between jupyter and codepen for workers, for quickly prototyping without losing full context

Hot reload fulfills 85% of that need, but it loses state between reloads

Interesting... you might want to look into the Chrome DevTools protocol. Miniflare supports starting an inspector server, which you can then send WebSocket messages to for evaluating code in the Miniflare context.

Alright, that might actually work even better than eval since I can also insert breakpoints and replace functions. Thanks for the heads up

Is wrangler3/miniflare3 planning to add support for breakpoints/debugging? 🙏

so uhm, the documentation for miniflare on miniflare.dev is wrong

``Property 'getKVNamespace' does not exist on type 'Miniflare'.``

local cloudflare development is total freaking hell ✨

Seems to be there 🤔 https://github.com/cloudflare/miniflare/blob/6bace6b464e1458ac3621d14d639750455299853/packages/miniflare/src/api.ts#L111

in miniflare 3 it may have been removed/renamed

but I'd recommend just using Wrangler, Miniflare hasn't been the recommended way to do local development/testing for a few years now

if only i could get sveltekit working with wrangler and local kv

i might just be daft, but doing local dev with cloudflare is not easy, and the documentation is in such constant shift you never know what's up

as of now i'm just creating a kv memory storage manually with miniflare and it works, just couldn't use the ``Miniflare`` class

PM for Workers here 👋 Thanks for the feedback. Updating and enhancing local documentation is in the works. Hopefully consolidating everything with Wrangler will reduce the need to figure out questions like - is this Miniflare or Wrangler. Sorry for the problems so far though. If I can help at all feel free to ping me directly. Also, we are aware of the sveltekit issue and are talking through solutions there.
