Run wrangler dev locally

[RaeesBhatti]

💡 Feature request

Describe the feature

It seems like my requests to wrangler dev are being routed to Cloudflare servers. This is causing unnecessary latency in when I make the changes and when they're realized in the server (~4-5 seconds). wrangler dev should run locally on local assets.

Describe the alternatives

Right now I'm stuck on a 500 Internal Server Error on all static resources. I'm not sure if I'm supposed to use https://github.com/cloudflare/kv-asset-handler locally or not or how to set it up in a wrangler dev setup. Do I have to upload the static files to KV before running wrangler dev?

I agree fully! There should be a way to develop and run tests locally without the requests being routed to the Cloudfare edge..
Never really understood why Cloudflare neglected this and usually points to 'wrangler preview/dev' as a replacement for a proper local environment. Back in the day there was support by the community but it is not maintained any more: https://github.com/dollarshaveclub/cloudworker

Other cloud providers such as Azure have support for local development environments. There should be an official support maintained by Cloudflare @rita3ko :)

In the mean time you can look into jdanyow's packages collection:

Oh yea, and there are so many issues with wrangler login, timeouts, bad gateways and panick, that would be mitigated with local development environment:

Thanks!

I've since published https://github.com/RaeesBhatti/cloudflare-kv-isomorphic which emulates Cloudflare KV API's when running locally on NodeJS. This allows me to develop the site without wrangler dev. It might be useful to some people.

I guess this is no longer relevant with the new miniflare release
