I am currently migrating my Next.js app to Cloudflare Pages. I have used SendGrids Web API to send emails (e.g. for my contact forms). That does not work after switching to the Edge runtime because SendGrid seems to use Axios to send their emails (as i found in my error message and analyzing the sub-dependencies). What is the go-to solution for such cases? Do I need to use SMTP relays or is there an easier solution?

Current error (after submitting a valid form to my edge runtime configured api endpoint):

[AxiosError: There is no suitable adapter to dispatch the request since :
- adapter xhr is not supported by the environment

not sure if you've checked out resend, they have an edge compatible lib,

for what is considered best practice, i think if you want to stay on cloudflare stack maybe using mail channels since they have a partnership with CF but that involves adding a worker if i understand it correctly (which i may not)

Hey i am using contentlayer and with nextjs and for this specific dynamic route, next-on-pages is asking me to make it run on edge but i get

James•1/21/24, 10:11 AM

For dynamic route SSG you need to tell Next.js to only generate the routes provided.

See how in https://github.com/cloudflare/next-on-pages/blob/main/packages%2Fnext-on-pages%2Fdocs%2Fgotchas.md

39dylan•1/24/24, 3:47 PM

Just wondering for edge runtime if we have dynamic routes (/blog/[slug]/blog/[slug]) is it possible say to turn a certain page into static e.g. /blog/1/blog/1 would it still count towards a function call? According to https://developers.cloudflare.com/pages/configuration/serving-pages/#route-matching "If an HTML file is found with a matching path to the current route requested, Pages will serve it. Pages will also redirect HTML pages to their extension-less counterparts: for instance, /contact.html will be redirected to /contact, and /about/index.html will be redirected to /about/."

Does this apply to static sites only or everything? My reason for doing this way is I have more than 20,000 pages (I'm forced to use edge runtime instead of static export) I plan to make the popular pages static so in theory it will reduce calling a worker functions. Would I have to also include these pages in routes.jsonroutes.json?

kev-ac•1/24/24, 4:37 PM

As everything except /_next/static/*/_next/static/* invokes the functions script even static pages in a next.js project are billable requests afaik. You can see this rule in a single deployment under functions (at the bottom). Provided you use next-on-pages.

Anyone get D1 working with local development? I've tried every blog post and looked through here and can't seem to figure it out. I would be happy with developing against the remote DB or local DB. Every time I'm in dev mode it seems to be connecting to an empty Sqlite DB that doesn't have any tables in it based on the errors. I've tried putting my remote DB name/ID in the bindings or a local one and i get the same results.

setupDevBindings({
      persist: true,
      bindings: {
        DB: {
          type: "d1",
          id: "local-test-db",
          databaseName: "coaching",
        }
      }
    });

setupDevBindings({
      persist: true,
      bindings: {
        DB: {
          type: "d1",
          id: "local-test-db",
          databaseName: "coaching",
        }
      }
    });

James•1/24/24, 9:48 PM

They will still invoke the worker as Kev said, unless they're in _routes.json. But excluding routes (instead of assets) from invoking the worker is generally not a good idea as non-static exports expect to be able to through a series of phases and rules for routing that Vercel defines for us.

There are still benefits to prerendering routes though, as it would reduce your final worker size, not need to spend cpu time to render the page, not need to make fetch calls during a render, and so on. So there are benefits still.

wesbos•1/26/24, 6:37 PM

Hey Folks- im trying to use KV/D1 inside a Server component, is this possible or only inside an API route? I can't find any examples online

I've got this in my next.config.js, but process.env.TESTKV is always undefined

if (process.env.NODE_ENV === 'development') {
  import('@cloudflare/next-on-pages/next-dev').then(({ setupDevBindings }) => {
      setupDevBindings({
        bindings: {
          // Add here the Cloudflare Bindings you want to have available during local development,
          // for more details on Bindings see: https://developers.cloudflare.com/pages/functions/bindings/)
          //
          // KV Example:
          TESTKV: {
            type: "kv",
            id: "TESTKV",
          },
        },
      });
  })
}

if (process.env.NODE_ENV === 'development') {
  import('@cloudflare/next-on-pages/next-dev').then(({ setupDevBindings }) => {
      setupDevBindings({
        bindings: {
          // Add here the Cloudflare Bindings you want to have available during local development,
          // for more details on Bindings see: https://developers.cloudflare.com/pages/functions/bindings/)
          //

  })

Donnager•1/26/24, 7:35 PM

im a n00b so don't quote me, but you should absolutely be able to access KV/D1 in a server component,

not sure why your setup is undefined, but i think you need to create a KV from local wrangler as well? could be totally wrong and/or maybe you already did this

in terms of wrangler.tomlwrangler.toml i believe the maintainer has a PR for that https://github.com/cloudflare/next-on-pages/pull/648 that will allow it to to be used seamlessly, there is an earlier chat where he describes it in this channel,

anyways others who are more knowledgable may be able to help more if you haven't already figured it out

not that i know of but may be possible, im a huge donkey so hope im not leading you down the wrong direction, even now im wondering if i actually did create the KV in wrangler, or if it didn't just automatically do that,

you probably already saw this but the internal github doc:

https://github.com/cloudflare/next-on-pages/blob/main/internal-packages/next-dev/README.md

https://github.com/cloudflare/next-on-pages/blob/main/internal-packages/next-dev/README.md

that says it generates from miniflare, so i feel like you may not need it locally, but can't remember how i set it up last time hehe

sathoro•1/27/24, 6:31 AM

I'm having some trouble with exceptions getting logged in Sentry and I think it is related to how Cloudflare Pages is bundling the application, but I'm not certain. basically if an error occurs locally, then it gets logged correctly as an exception to Sentry. but when deployed on Cloudflare Pages, it is getting logged as a console error message and not an exception.

we are still using NextJS 13 and the old version of next-on-pages

I tried adding a custom _error.js file like here but then it gave an error when building and said I need to specify that as an edge route, which I don't think is what I'm wanting to do?

James•1/27/24, 10:27 AM

getInitialProps can probably run on the server i imagine, so it will try to generate an node.js function I would assume. It's also a legacy API so your mileage may vary.

I don't know how sentry works, but the error it's logging could be the one that we catch and then log via console.error after running an edge function, but I'm not sure how sentry works so unsure if that's what's intercepting
