Experiment: Next.js via `serverless` target.

[ryan-roemer]

• [x] Have a target: "serverless" build.
• [ ] Bridge routing with next-aws-lambda or something similar to target one base Lambda
• [ ] Assess package size
  • [ ] Check if there are duplicates across page bundles and see if we can tweak Next.js webpack config to split common chunks out.
• [ ] Verify correctness.

Update

In https://github.com/FormidableLabs/nextjs-serverless-demo/tree/experiment/nextjs-serverless-mode we've got a very minimal POC up with:

• No routing. Just shows the index page for any route match
• No assets or anything. Just broken links.

... but it works in the following scenarios:

• Behind domain: https://nextjs-sls-sandbox.formidable.dev/blog/
• APIGW url: https://zbea7sdrji.execute-api.us-east-1.amazonaws.com/sandbox/blog/
• yarn lambda:localdev: http://127.0.0.1:4000/localdev/blog/
• yarn dev: http://127.0.0.1:3000/

Package stats:

$ du -sh .serverless/blog.zip 
900K    .serverless/blog.zip
$ zipinfo .serverless/blog.zip | wc -l
      85

Next up, routing to different pages...
