feat: vercel edge sdk

[monsagri]

[sc-194414]

This adds an Edge SDK for Vercel to be used with Vercel Edge Configs.

I've added some basic testing, and using the built package in a vercel project using npm link works as expected.

This pull request has been linked to Shortcut Story #194414: Update the SDK to pull in config from Vercel.

Leaving this for a follow up PR as it's a nice to have

If vercel has fetch, then it should be possible. Not sure on the value, because I have not really been in the loop how we use these edge SDKs and why it is fine for them to not send events.

[InTheCloudDan]

I left a slack comment for @yusinto in regards to Cloudflare. When we go to enable events we want to also add in the track call. I'm not sure if it's waiting until sendEvents is usable to add that in.

[kinyoklion]

Yeah, we probably wouldn't want to add it before it actually sends events.

[kinyoklion]

We figured we would need a shared folder for some potentially common edge provider items, but it is hard to say for sure until you make 2. :-)

Please take a look at #83 which has the common code for cloudflare and vercel refactored to packages/shared/sdk-server-edge.

Got it thanks! Actually had a scroll through already and will be making sure to get this updated today/tomorrow latest

Thanks for doing all the heavy lifting with the shared stuff!

No worries! Thank you for doing the Vercel sdk. I have merged #83 now so you'll be able to use it from main which makes it easier.

Please take a look at #87 for producing cjs and esm bundles for the cloudflare sdk which you will need for Vercel also. TLDR your build command should use scripts/build-package.sh which will do the job. The relevant code are:

  "type": "module",
  "exports": {
    "require": "./dist/cjs/src/index.js",
    "import": "./dist/esm/src/index.js"
  },
  "main": "./dist/cjs/src/index.js",
  "types": "./dist/cjs/src/index.d.ts",
  "files": [
    "/dist"
  ],
  "scripts": {
    "build": "../../../scripts/build-package.sh",

The Cloudflare SDK 0.0.1 has been published. All code are in main now so you can safely follow the cloudflare sdk for vercel. Let me know if everything makes sense. Good luck!

[monsagri]

I've made the changes that we talked about and adapted everything to use the new common modules where possible.
Missing some tests against the main implementation for now using something like miniflare to mock the edge config, but think that can come as a follow up?

[yusinto]

Nice work! I requested some changes but nothing serious.

You will also need to modify release-please-config.json for the initial publishing of this package. See this.
