Could not resolve "@cloudflare/pages-plugin-mailchannels"

I'm trying to set up a contact form for a simple Pages site but the instructions on https://blog.cloudflare.com/sending-email-from-workers-with-mailchannels/ just result in a

Could not resolve "@cloudflare/pages-plugin-mailchannels"

Could not resolve "@cloudflare/pages-plugin-mailchannels"

error when I make a new push.

npmjs.com seems to indicate that

@cloudflare/pages-plugin-mailchannels

@cloudflare/pages-plugin-mailchannels

still exists and has over 1,000 weekly downloads, which suggests it hasn't been renamed, but I have no experience with Cloudflare Workers and I find the distinction between using Workers and using Pages Functions hazy and confusing, so I don't know how to go about testing the "must be manually added as a dependency first" hypothesis with Git-based deploy (the docs just talk about Wrangler) and it being located in

functions/_middleware.ts

Send email using Workers with MailChannels

MailChannels has created an email sending service specifically for Cloudflare Workers that removes all the friction associated with sending emails.

Have you added the package using a package manager like ? The Pages build environment will install the dependency if it's in the package.json.

So I do need to use ? The docs were very unclear about whether that was specific to the Wrangler-based deployment. Currently, it's deploying from a folder containing only the folder and some HTML generated by a custom Rust-based static site templater.

You need to do something to install it

The Pages build environment just calls npm install & Wrangler for you

OK, so I just initialize a dummy NPM project in the root of the Git repo and add the plugin as a dependency?

ssokolowOP•12/16/23, 8:58 PM

Nope. There's now a and a specifying

@cloudflare/pages-plugin-mailchannels

@cloudflare/pages-plugin-mailchannels

as a dependency in the root of the repo and I still get

This person figured it out. → https://github.com/cloudflare/workers-sdk/issues/1925#issuecomment-1382234959

You need to set your build command to if you want to add this sort of thing to a "no framework" Cloudflare Pages site that's just pulling pre-generated HTML from a Git repo.
