    🤠 wrangle your Cloudflare Workers

    Here are things I ran into.

    `wrangler login` doesn't work if I'm not already logged in to CloudFlare website. If I have to login first, it doesn't do whatever necessary redirect it should do so most of the time I have to run `wrangler login` twice.

    `wrangler dev` is slow.

    `wrangler dev` requires root domain.

    I also feel that the interaction between DNS settings and workers is under-documented, probably because it crosses responsibility of two different teams.

    For example, it took me way too long to figure out that if I have a workers-only website for, I have to put dummy DNS entry for

    Frankly, despite reading wrangler docs multiple times, I don't think I fully understand the interactions between what's in the DNS, what's in the workers route and further more if you add pages to the mix.

    Docs should explicitly spell out DNS / routes setup for most common scenarios like: 1) workers-only site (no proxying to any other server) 2) workers in front of a proxied website

    Workers should be seamlessly integrated with pages i.e. pages should just automatically recognize and use workers-site/ directory on deploy.

    I don't think setting up pages automatically configures DNS settings for its domain, which it obviously should (might be mis-remembering).

    Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.

    Run a Cloudflare Worker Locally

    I'm very happy about this, an official support to run Workers locally. I invested some of my personal time to get this tool, I submitted a patch on a community project (since Cloudflare wasn't officially supporting this). I think it was a very important missing piece for me to consider Workers a serious development tool.
