    Middleware still run before static assets.
  • g
    So you'll need to do something like
    Copy code
    ts
let response = await env.ASSETS.fetch(request)
if (response.status >= 200 && response.status < 400) return response

return new Response("My dynamic Functions response")
  • c
    would something like this work?
    Copy code
    js
export const onRequestGet = async ({ request, env, next, data }) => {
    let pageData = await next();

    if (pageData.status === 404) {
        // Do stuff
    } else {
        return new pageData;
    }
};
  • g
    Yup, pretty much the same sort of thing as what I posted 🙂
  • c
    I see. I'm not too familiar with env.ASSETS
  • g
    next()
    is probably nicer than 
    env.ASSETS.fetch
    in case you've got things further down the handler chain
  • g
    env.ASSETS.fetch
    is just a shortcut right to the bottom
  • b
    Thanks for both of your help, really appreciate it
  • c
    off-topic question, could you use to env.ASSETS.fetch a separate static assets? like if I trying to build a page or serve a custom asset, could I grab 
    public/img/something.png
    ?
  • g
    Yup.
  • c
    neat! I should probably start doing that
  • g
  • g
    But we'll get them worked out soon
  • e
    I'm assuming it's on an unbound worker then rather than bundled worker?
  • c
    @User it's bundled
  • c
    I'm doing another build with bigger image + more complexity & color blending. I'll post back when I get it going
  • w
    I'm currently building a SvelteKit application and when developing locally the endpoints run Nodejs and therefore I can use packages like 
    crypto
    , but once I build it, because Cloudflare workers have a different Javascript environment it fails and returns the following errror: 
    Could not resolve "crypto" (use "platform: 'node'" when building for node)
  • c
    for crypto, you're gonna want to use https://github.com/panva/jose
  • c
    essentially, you can use most packages that follow ES6 (think 
    import {} from "..."
    rather than 
    require("...")
    ), and don't rely on 
    document
  • w
    thanks for the answer @User but it seems this package does not have SHA512 hashing
  • w
    and that's what I need the most
  • g
  • w
    this fails on Sveltekit in dev mode
  • g
    Copy code
    ts
const myText = new TextEncoder().encode("Hello world!")

const myDigest = await crypto.subtle.digest(
  {
    name: "SHA-512",
  },
  myText, // The data you want to hash as an ArrayBuffer
)

console.log(new Uint8Array(myDigest))
  • g
    dev mode? You mean with wrangler?
  • w
    no, I don't need Wrangler because I'm using the cloudflare-adapter
  • w
    when I use this 
    crypto
    lib it returns the following error
  • w
    crypto is not defined
  • g
    Yeah, you'll need to use wrangler.
  • g
    I imagine SvelteKit's local runner thing is using Node, which won't have Web Crypto available
