What tool do y'all use to create your diagrams in your guides?

Ok, I found the problem. I realised that all of the routing was having and issue and after some Googling, I found that it is caused by the way StrictMode works with React Router. in https://serverless-stack.com/chapters/handle-routes-with-react-router.html you need to make sure that the Router component wraps StrictMode, not the other way around.

Copy code

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
  <Router>
    <React.StrictMode>
      <App />
    </React.StrictMode>
  </Router>

Hi Folks. I’ve just started working with SST at our company. I’m quite a fan of CDK and this is looking very nice. Would anyone be able to guide me to best practices for working with mid size dev teams 8-12. How do we avoid constantly stepping on each other when working locally? Won’t’ we be deploying the same stack over each other? I have multiple accounts per environment. But if I try to create multiple accounts per developer, my infra costs would be massive. Some of my resources are EC2 instances. Any ideas would be wonderful.

Hi people. Just noticing that the example repos associated with guide for things like structuring and organizing projects, and sharing code between services are like 2-3 years old. Can anyone suggest any recent repos and/or resources that demonstrate best way to use current version of SST? Or any real-world open source projects / repos that reflect current best practices? Thank you! Example of guide with old repos: https://serverless-stack.com/chapters/organizing-serverless-projects.html https://serverless-stack.com/chapters/share-code-between-services.html

I found a typo in https://docs.serverless-stack.com/installation .

scope

seems to be a typo for

stack

. Am I right?

Copy code

export function MyStack({ stack }: StackContext) {
  scope.stage; // "dev"
  scope.region; // "us-east-1"
  scope.name; // "my-sst-app"
}

Hey guys 👋 I started with Docs -> Installation rather than the Guide, so I created a Typescript project with

npm init sst

. The project uses

@serverless-stack/resources 1.0.4

which appears to be incompatible with some of the other docs. For example, https://docs.serverless-stack.com/api#authentication refers to

defaultAuthorizationType

which does not exist in the API props in this version. I found some other examples of this, for example

cognito

is missing from Auth props. If however I use

npx create-serverless-stack@latest --language typescript myproject

as per the Guide, the project uses

@serverless-stack/resources 0.69.7

which appears to be aligned with the Docs as well as the Guide. Can you please advise on the recommended version and command to create a new project? Unless I've missed something obvious, it may also be worth updating the docs.

I think there is an error in the migration guide here in the code block: https://docs.serverless-stack.com/constructs/v0/migration#default-settings Instead of

Copy code

// to
{
  defaults: {
    functionProps: { timeout: 10 },

it should be

Copy code

// to
{
  defaults: {
    function: { timeout: 10 },

Or at least I get a complaint in the console with the former, but not the latter setup

Hey guys, found a typo in the API example: https://serverless-stack.com/examples/how-to-create-a-rest-api-with-serverless.html Deploying your API The command for deployment should be: npm run deploy -- --stage prod

Hey crew! Jumped into the

Deploy to S3

section, looks like this line is outdated:

This packages all of our assets and places them in the build/ directory.

The Next.js docs indicate the output goes into the

.next

folder: https://nextjs.org/docs/deployment Could be that this is IRT a config earlier in the guide but figured I would flag regardless.

It's in preview-ish still, but is there plans to update https://docs.serverless-stack.com/migrating/serverless-framework in light of CDK adding official support for importing existing resources into CDK stacks? This is the biggest thing that concerns my teams since we have a lot of a Serverless FX repos with active prod deployments, and the overheard of conversion is pretty scary.

I was looking into tagging the DebugStack the same way as the normal stack tried using key values from a

.env

file. While all worked as expected for my normal stack, the tags were missing in the DebugStack. The reason for that is the changed run directory during debug stack initialization, which means the environment isn't behaving as I expected.

Just downloaded and tested SST last night. Liking it a lot so far. Noticed some small updates with the docs that can help first time devs/ops

Off the back of a discussion about not using Cognito for auth, I'm running through the Auth0 tutorial and have come across a bug. When outputting the stack outputs,

Copy code

IdentityPoolId: auth.cognitoCfnIdentityPool.ref

is not recognised. I had to change to

IdentityPoolId: auth.cognitoIdentityPoolId ? auth.cognitoIdentityPoolId : "none",

To get it to work correctly.

@Frank @Jay Would you also be interested in a guide how to specify a custom bucket for CDK assets? This was another one of my pain points before as we might have many projects. The serverless framework allowed using 1 customizable deployment bucket for all. The current documentation covers an option for debug payloads, but not for the general CDK deployment bucket that's used for all other assets.

I tried this:

Copy code

export default function main(app) {
  app.setDefaultFunctionProps({
    runtime: "nodejs16.x",
    srcPath: "backend",
    bundle: {
      format: "esm",
    },
  })

  const storageStack = new StorageStack(app, "storage")

  app.stack(storageStack).stack(ApiStack)
}

but now get:

The Auth0 example has been updated to V1 and it now includes a React frontend to call APIs. 👉 https://serverless-stack.com/examples/how-to-add-jwt-authorization-with-auth0-to-a-serverless-api.html Thanks @Ashishkumar Pandey for the tips!

Hey, we are running our full production setup on AWS-CDK without SST currently. We’re very interested into using SST for development, but would not want to touch our production setup. Is there a guide how to / is anyone using SST for development only, but using “pure” aws-cdk for production?

I’m getting troubles getting started with the Apollo guide, https://serverless-stack.com/examples/how-to-create-an-apollo-graphql-api-with-serverless.html Looks like the config changed recently and playground is not longer supported.

how do you pass vars like cognito user pool, appsync url, etc from serverless infra to nextjs? is this the best way to do it? https://docs.serverless-stack.com/constructs/NextjsSite#environment-variables are there any helpers for reading in the vars or should i make my own?

Folks, a quick heads-up that the postgres example has quite a few issues. I've fixed a few along the way but now I'm into type errors within KyselyTypeGenerator.js. It looks like the base setup has been changed to typescript but the rest of the content hasn't.

Howdy! I’m new on SST, coming from Serverless Framework and now considering if I should go with SST or pure CDK. One thing I’m wondering about is how SST sees the difference of monolith lambdas vs microservice? I couldn’t find any comments on it in the documentation. My aim is to primarily code in python. So if I wanna deploy say 5 different functions, is there a nice structure on how to manage this to get separate requirements.txt files for them etc? Or am I overocmplicating things.

https://serverless-stack.com/chapters/dynamically-generate-social-share-images-with-serverless.html Hi! Quick question about this guide. Since there is a cloudfront distribution with TTL of a year. There is no need to save the captured images to an s3 bucket right? Without the s3 component but with the same cloudfront configuration it would get run once, image would be captured on the fly and returned, and the result would be cached by cloudfront for a year so the api would never trigger again for the same social card request? Or is there something I'm missing? Just wondering because this guide is great and we're going to use it but the s3 + cloudfront felt like doing the same thing twice in terms of permanent caching
