Remote Dev
In the past, I had to import miniflare explicitly and check if it was in dev for setting access to D1 under dev. The new project I started to test wrangler/miniflare 3 does not need that and it works well, but it is always local.
You can point a Worker at the local
You can point a Worker at the local bucket, then have the Worker itself serve the API
HTTP Header size limit
How do I change the max http header size for miniflare? The node configuration flag does not appear to work (node 20.11.1). Is there another option needed? A little digging showed that undici could potentially be causing issues but I wasn’t sure if that mattered within workerd or not
@MrBBot I'm trying to use a WASM binary
@MrBBot I'm trying to use a WASM binary with the Miniflare API but running into one major issue. I'm using
esbuild to bundle each worker so I can watch for changes and run 17 workers from a single process. The trouble is esbuild is getting to the './foo.wasm' import first, which is resulting in the CompileError: WebAssembly.instantiate(): Wasm code generation disallowed by embedder (I think that's because the WASM plugin is shoving it into a namespace rather than allowing Miniflare t...Thanks Adam! I got to try it out this
Thanks Adam! I got to try it out this morning after sending that message and it felt really good. I wrote a thing using Miniflare 3, Prisma and Vitest https://github.com/vladinator1000/prisma-vitest-miniflare
Applying D1 migrations in tests
I don't know how to get this working.
```ts
import { Miniflare } from 'miniflare';
import { afterAll, beforeAll, describe } from 'vitest';
import { spawn } from 'child_process';...

does anyone know why the jest environment for miniflare would have changed the functioning of
global so that I now have to use globalThis? starting in version 3 I thinkNot sure if anyone already suggested
Not sure if anyone already suggested this nor if it's the right place for suggestions, but would be awesome to have a persistent price consumption simulator of all services on miniflare.
It could keep track of requests to KV, DO, R2 and all the other services during runtime, compare them to each service pricing and subtracting free-tiers where available.
It would be useful to understand if there is a major bug in our code and see an example of bill per month before deploying to production, and (I hope not) waking up in the middle of the night with missing funds on our credit cards 😄
Sounds plausible?...
Unable to get local issuer certificate
hi again 🙂 I'm getting this error

it only appears when I use service bindings like this:

workerd's logging. Wrangler actually uses the DevTools inspector protocol for logging instead.Hey there I found a behavior difference
Hey there, I found a behavior difference between miniflare (via wrangler latest version) and a deployed worker: when using
env.R2_BUCKET.put(key, request.body) you will get an error like "Provided readable stream must have a known length (request/response body or readable half of FixedLengthStream)".
1. It's working when deployed on Cloudflare workers
2. It's a request.body...Any idea for when there will be
Any idea for when there will be analytics engine support with miniflare?
Cache deserialization error
CacheError [ERR_DESERIALIZATION]: Unable to deserialize stored cached data due to missing metadata.
The cached data storage format changed in Miniflare 2. You cannot load cached data created with Miniflare 1 and must delete it.

Is wrangler3 miniflare3 planning to add
Is wrangler3/miniflare3 planning to add support for breakpoints/debugging? 🙏
I was gonna use miniflare jest to test
I was gonna use miniflare-jest to test my worker by making fetch requests to it, as seen in https://miniflare.dev/testing/jest#writing-and-running-tests. I guess we could call theses "integration tests". Can you confirm this is the right way (I guess so, given the doc).
🔌 Multiple Workers · Miniflare
Hi, I have a main worker which has service bindings to two other workers. I would like to create jest integration test for the main worker. I have the directory structure similar to the one in https://miniflare.dev/core/mount and the main worker wrangler.toml has [miniflare.mounts] [build.upload]. I am creating a miniflare instance in the jest test file with a script path
`describe('bluegreen routing', () => { const mf = new Miniflare({ envPath: true,...
