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"
error when I make a new push.
npmjs.com seems to indicate that @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
.The Cloudflare Blog
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
npm
? The Pages build environment will install the dependency if it's in the package.json.So I do need to use
npm
? The docs were very unclear about whether that was specific to the Wrangler-based deployment. Currently, it's deploying from a build
folder containing only the functions
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?
Nope. There's now a
package.json
and a package-lock.json
specifying @cloudflare/pages-plugin-mailchannels
as a dependency in the root of the repo and I still get Could not resolve "@cloudflare/pages-plugin-mailchannels"

You need to set your build command to
npm install
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.GitHub
