Cloudformation template

Trying to deploy Nextjs 13 using open-next with Serverless/Cloudformation.

Currently unsuccessful, but this is the start template I currently got, hope this could help some of you and can even help me debug it and make it work.

First of you will need the next 3 Serverless plugins to execute scripts, sync build to S3 and configure Lambda@Edge:
```
npm i --save @silvermine/serverless-plugin-cloudfront-lambda-edge serverless-s3-sync serverless-scriptable-plugin
```
Here is the full serverless config template file:

service: nextjs-app
useDotenv: true

plugins:
  - serverless-scriptable-plugin
  - serverless-s3-sync
  - '@silvermine/serverless-plugin-cloudfront-lambda-edge'

I'm in the process of moving this to Terraform, does anyone have a CloudFormation template that includes middleware? Still trying to understand how that works. The docs mention API Gateway, but I cannot find any information on that.

Thanks for the template @teriu, super helpful!

So, to add middleware, that function needs to be added as a viewer request lambda function association on the default and /_next/data/* behavior.

I'm getting Access Denied from cloudfront url after using this exact config. Is it working for everybody else?

@mrunbanked have you tried going to a public asset such as <your url>/_next/static/favicon.ico (if it exists?) access denied there would mean that the distribution itself does not have access the the S3 bucket.

I have it working on Terraform, and your template is almost identical, with the slight difference that

I'm using an origin access identity for my S3 origin config on the static origin.
I'm using that origin access identity's ARN as the AWS principal for the S3 bucket policy.
I'm using RegionalDomainName rather than DomainName in the DomainName parameter of the static origin.

Ok seems like something was wrong with my package versions so server wasn't working properly. After updating all the packages it works! thanks 🙏

and it is deploying fine as far as I can see now.

watch https://github.com/serverless/serverless/issues/11424 you should not use the serverless dashboard. The app/org in the serverless.yml destroys the lambda... -

This issue is referenced in the README as being open-next being compatible with Serverless Framework, but I'm a bit confused. Is @emulienfou's post a question or is it the answer? It's the only config file I see that references lambdaAtEdge, so is edge working?

I understand the open-sourced-ness of this, so if the answer is I need to figure it out, that's fine.

Hi @mbaquerizo I post a started template for Serverless Framework. It's not working properly at 100% at the time of the post. If you check the other answers you should be able to make it work by adapting all the examples of the templates

I could make it work propperly on serverless framework with this configuration. Not sure about cache-related stuff, though

I've added the two missing lambdas (warmer and revalidation) to the mix and the missing variables, as per-doc. And aws is now enforcing s3 bucket ACL deprecation, preferring and defaulting new buckets to bucket policy only, disabling ACL by default. My open-next version: 2.3.6 (latest, as I spoke) EDIT: It works ~, except for this problem: https://github.com/sst/open-next/issues/373~ 🟢 The issue regarding sharp is workarounded, and as far as I undertand, lies in next version itself, but the workaround worked, and I've updated the example below. ~EDIT 2: I've ported an already existing next app running as standalone on a container, so I'm currently trying to figure out with the app developers why fonts and the theme isn't loaded propperly on use-client pages.~ 🟢 The serverless hooks plugin cannot read environment variables propperly, so I've written a JS script that loads environment variables and then runs the same build and zip commands, and call it there instead ~EDIT 3: The site deployed using this solution instead of our previous solution (Fargate + Load Balancer) feel much less snappier for some reason. Not quite sure why, yet..~ ~EDIT 4: For some reason, the 'public' directory assets (including /images) seems to be inacessible through cdn~ 🟢 It was because the public directory is at the root of the assets bucket (in my case / vercel default), so I've just added a handler for any files at the root or inside a subfolder of the bucket (it may be safer to specify the exact extensions, perhaps). It solved the slowdown like magic. Just updated the example below

At the docs, there is a "Dynamo provider". In the .open-next directory there is a "dynamodb-provider" (it does not finishes with "-function"), but I thought it was not a lambda. It seems I was wrong, despite it isn't in this docs drawing:

Open-next Infrastruture But it is mentioned here https://open-next.js.org/advanced/architecture#dynamo-provider-function. Is it actually a lambda?
