Hello, I’m Allie!•8/18/23, 8:16 PM

Maybe that’s why D1 didn’t work, since it has to be run through Wrangler to work

H

Hello, I’m Allie!•8/18/23, 8:18 PM

Though there may be an update that removes the need for a shim

H

Hello, I’m Allie!•8/18/23, 8:18 PM

We do still recommend using Wrangler when using Functions though

Ok well when I upload via the web UI — which doesn't mention this limitation — I would get a KV binding and a binding to

Hello, I’m Allie!•8/18/23, 8:24 PM

IIRC, D1 Bindings, under the hood, are just a fetcher instance. When building with Wrangler, it will insert a shim that takes all the calls to env.D1, formats it a certain way, then passes it in to the Beta DB binding you found

H

Hello, I’m Allie!•8/18/23, 8:24 PM

So since you didn’t run wrangler to deploy it, it never inserts the shim, and thus D1 queries don’t work

kian•8/19/23, 3:57 AM

If you just want a quick idea of what's in it, try this instead:

const formData = await request.formData();
console.log(Object.fromEntries(formData))

const formData = await request.formData();
console.log(Object.fromEntries(formData))

const formData = await request.formData();
console.log(Object.fromEntries(formData))

const formData = await request.formData();
console.log(Object.fromEntries(formData))

You might be trying to use SSR, SSR depends on functions to load the page

Dahoom•8/20/23, 2:16 AM

Without functions you would probably have to make it a static site for it to work

Johtozo•8/20/23, 10:19 PM

Question specifically on Pages. I have a case where I have a template page and a Function, specifically HTMLrewriter. Whenever that template page is visited, the Function runs to - say, replace the inner content of

<p>

<p>

for now. The end goal is to mimic a "site generator" (you can sorta think about it in terms of includes, I suppose - I'm aware there's stuff like Jekyll but this is more of a learning than using the "correct" resources) but I'll just go with replacing elements for now.

For whatever reason, it just hasn't been working for me, and I think it's because I can't really wrap my head around either requests or routing. So, two questions:

(1) Is the function at

/functions/index.js

/functions/index.js

/functions/index.js

/functions/index.js, for example, automatically invoked when I visit

index.html

index.html

at the root? Or do I actually have to call it, somehow?

(2) I'm not really sure I'm understanding requests - I would assume visiting the page is a form of a request, which would call the worker? But it's just not working for me, unless the problem lies with the rest of the code.

I've scoured the documentation and I guess I just need someone to explain it with a bit more words

IEatBeans•8/21/23, 3:05 AM

This may be more relevant to workers in general, but is there any way to set the timezone on a production function, or change it on wrangler? I built lots of time related logic, and then realized it all breaks in prod because the workers run on UTC and my local machine runs on my time zone

None at all, hmm.

Here's my worker at

/functions/index.js/

/functions/index.js/

/functions/index.js/

I've refactored the HTMLrewriter example to be a pages function

`export async function onRequestGet(context, env) {
      const OLD_URL = "developer.mozilla.org";
      const NEW_URL = "mynewdomain.com";

          this.attributeName = attributeName;
        }
        element(element) {
          const attribute = element.getAttribute(this.attributeName);
          if (attribute) {
            element.setAttribute(
              this.attributeName,
              attribute.replace(OLD_URL, NEW_URL)
            );
          }
        } 
      }
  
      const rewriter = new HTMLRewriter()
        .on("a", new AttributeRewriter("href"))
        .on("img", new AttributeRewriter("src"));
  
      const res = await fetch(context, env);
      const contentType = res.headers.get("Content-Type");
  
      // If the response is HTML, it can be transformed with
      // HTMLRewriter -- otherwise, it should pass through
      if (contentType.startsWith("text/html")) {
