feat(vite-plugin): allow env override for wrangler config path

[vimtor]

Frameworks like SST might autogenerate wrangler files for deployments.

Currently this requires users to do the following:

import { defineConfig } from "astro/config";
import cloudflare from "@astrojs/cloudflare";

export default defineConfig({
  adapter: cloudflare({
    configPath: process.env.SST_WRANGLER_PATH,
  }),
});

Source from the Astro component.

To make the integration easier, this pull request adds the ability to specify the configPath via the CLOUDFLARE_VITE_WRANGLER_CONFIG_PATH environment variable.

This way, frameworks built on top of Cloudflare can automatically configure wrangler without users needing to change anything.

  • Additional testing not necessary because:
• Public documentation
  • Cloudflare docs PR(s): Vite wrangler config path environment variable cloudflare-docs#30044
  • Documentation not necessary because: I could document this

Just to be clear, are you suggesting that SST would write its Wrangler config file path into the CLOUDFLARE_VITE_WRANGLER_CONFIG_PATH env var rather than the SST_WRANGLER_PATH env var?

LGTM but getting a second opinion from the rest of the Vite plugin team

that's right, that way users wouldn't need to specify a configPath in the Vite config

Checked with @jamesopstad - we are good to land this
