I'm putting the _middleware file at the root of the functions folder, and it runs for every route

The problem is, i only want to rewrite some HTML, and its consuming extra function invocations for nothing when it doesn't hit a page route.

You could use

_routes

to exclude an

assets

dir or similar from running Functions: https://developers.cloudflare.com/pages/platform/functions/routing/#functions-invocation-routes

Nice! That seems to be exactly what i was looking for. Thanks!

Just wanted to follow up about this, still can’t seem to get it to work.

How are you publishing this?

wrangler pages publish .

?

Oh your Function's format isn't correct either

Functions use Workers under the hood, but they don't run Workers via

addEventListener

and such. You need to use specific Functions syntax like

onRequestGet

, etc: https://developers.cloudflare.com/pages/platform/functions/get-started/

Through GitHub, I will try to use wrangler though and adjust the syntax thanks!

Is there a way to get the source URL in a function? I want to redirect the person back to the page they came from but haven't found a source url in the context

How did they originally get to your Function? Via a redirect?

form submit click (POST request)

I'm sending my email sign up form to a function that pulls out the email and stores it in KV here https://justingarrison.com/ it just redirects back to the home page with

?email=submit

to disable the subscribe button. But I also have a signup form at the bottom of the posts eg https://justingarrison.com/blog/2023-02-23-ec2-names-explained/ and I'd like to send them back to the post they were on. My only thought was to create a hidden field part of the form that contains the path and use that in the function

I wasn't sure if that data already existed in the context

```js req.headers.get("referer") ```maybe?

Thanks, I'll give it a shot

Just a quick question for dynamic routing, I want to match sth like

/

,

/foo/bar/.../

, or

/foo/bar/baz

, or

/**/*.html

or

/**/index.html

, but not

/**/*.js

or

/**/*.css

, (or .jpg, .svg, .txt, .webmanifest, .json or so), is it doable currently with dynamic routing ?

Anyone have an idea how to insert values into a local KV for local development with pages functions? Starting command line is

npx wrangler pages dev --kv=USER -- npm start

I'm trying to seed something in the USER namespace

before my code is called

do it yourself

just create a file at

.wranlger/state/kv/<bind-name>/<key>

with the value as content

Great suggestion .. but it does not work. Here's what I did: 1. ran my test instance

npx wrangler pages dev --kv=TEST -- npm start

2. created a file:

~/.wrangler/state/kv/TEST/BUG_TEST

3. put the value 'TEST1' inside BUG_TEST 4. Read the value from file:

const test = await context.env.TEST.get('BUG_TEST');
  console.log(`test=${test}`);

5. Got the value 'null' 6. To confirm the namespace works I did another test right after:

await context.env.TEST.put('BUG_TEST','THIS IS A TEST');
  const after = await context.env.TEST.get('BUG_TEST');
  console.log(`after=${after}`);

7. This one yielded "THIS IS A TEST"

why

~/.wrangler

, it should be

./.wrangler

Since you did

await context.env.TEST.put('BUG_TEST','THIS IS A TEST')

, you should have already have that file right

According to the docs, it puts it in memory

Also, I realized that wrangler is installed in my node_modules, since I'm invoking it with npx

tried a file there with same results

No it should be just at its working dir, or let's say "project root" if it is its working dir.

Ahh ok you need

--persist
