Suggested improvements for the Next.js example

Amazing, just sharing my experimentations with this: Notes:

• Not sure if needed the npm install & open next build step, IMO that should be handled by the user or CI before triggering the deployment, or it should be generic, ie "build command".
• Doesn't use/deploy the warmer lambda Did play modifying this to deploy to lambda@edge Notes:
• Doesn't use/deploy the revalidation lambda function
• Doesn't setup cloudwatch (not sure if edge specific or not), terraform examples I've seen do mention something about cloudwatch.

What I've learned about making @edge lambdas, since I couldn't find anything on Pulumi docs, to deploy a lambda to edge the steps are:

• lambda needs to be on us-east-1 region

ie: just deploy everything to us-east-1, or pass the provider only to the edge lambda (didn't try)
const useast1 = new aws.Provider('useast1', { region: 'us-east-1' });
const site = new NextJsSite(_prefixWithAppName('mysite'),
  { path: '../' },
  { provider: useast1 },
);

• adding the lambdaFunctionAssociations on the/a cloudfront behaviour
  • where the arn is .qualifiedArn
• on the lambda enable "publish" flag
• serverFunction role needs to include edgelambda role: ... Service: ['edgelambda.amazonaws.com', 'lambda.amazonaws.com'] ...
• lambda arch needs to be x86_64
• lambda cant take any env variables. (not sure if there's a use case for this) I only changed the server lambda to run on edge so not sure if image lambda can be deployed to edge as you are adding BUCKET_NAME & BUCKET_KEY_PREFIX env vars.

Looks kind of simple to support edge deployments, the terraform example I've seen does it based on a flag using different settings based on it.

I've looked at https://github.com/RJPearson94/terraform-aws-open-next for context lambda main

How about you create a library for the custom resource? It would quickly become the standard for NextJs + Pulumi, rather than having to copy paste from the example code all the time. I see a NextJs app and its related resources as 1 component, that either exists as a unit or not

Strongly agree with this, could be a huge boost for people to switch over to Pulumi over vercel, sst, railway and flightcontrol if there is a simple imported library with one configuration object and plug and play instead of a big template.

Would also be much easier to contribute to.
