feat: add platformProxy option to configure getPlatformProxy

[vnphanquang]

Note

I've run check & lint but not all test scripts because I don't see any specific tests in the two packages' package.json, and some of tests fail on my machine (chromium-dev related) but I don't think they are related to the change here.

Context

Today, adapter-cloudflare and adapter-cloudflare-worker use Wrangler API's getPlatformProxy for platform emulation during dev & preview, but not yet allow passing configuration parameter to getPlatformProxy. This PR adds a platformProxy adapter option to do just that.

Use case

My specific use case is to set persist.path to a custom directory (equivalent to the --persist-to flag when using wrangler CLI). This allows me to set up two SvelteKit projects in a monorepo to use the same local sqlite database during dev & preview.

Please don't delete this checklist! Before submitting the PR, please make sure you do the following:

• It's really useful if your PR references an issue where it is discussed ahead of time. In many cases, features are absent for a reason. For large changes, please create an RFC: https://github.com/sveltejs/rfcs
• This message body should clearly illustrate what problems it solves.
• Ideally, include a test that fails without this PR but passes with it.

Tests

• Run the tests with pnpm test and lint the project with pnpm lint and pnpm check

Changesets

• If your PR makes a change that should be noted in one or more packages' changelogs, generate a changeset by running pnpm changeset and following the prompts. Changesets that add features should be minor and those that fix bugs should be patch. Please prefix changeset messages with feat:, fix:, or chore:.

Edits

• Please ensure that 'Allow edits from maintainers' is checked. PRs without this option may be closed.

Also very interested in this 👍 Is there anything that can be done to move this forward?

My use case is the following (I believe it is not that uncommon):
I have multiple sveltekit apps in a monorepo. They all share the same bindings, so the wrangler data folders need to be at the root of the monorepo, not in each single package. This can be configured in the options of getPlatformProxy(), therefore this PR would fix that issue 🎉

+1 to this. Same exact use case over here. I'm currently using a patched version of the adapter-cloudflare package to workaround this.
