Serverless Stack

Is there a way to setup vscode to debug a lambda? Even if it times out in 30s (api gateway / appsync).

I don’t have experience with vscode peronally.. but I think <@U01NDPM3NDT> and <@U01P4FAAD9P> were using vscode with  `sst start` to inspect the state.

<@U01RHT7GSD6> yup, setup is really simple. In VSCode's debug view you want to debug from `Run Script` and give it a `npm` script, `start` in our case

From there you can set a breakpoint and inspect the state of the stack and in-scope variables

Nice! I'll give it a try soon, will that let me inspect only the stack or can I also breakpoint on a lambda?

Cliff, but we were debugging SST stuff, not a lambda.

i was checking and there's a AWS toolkit for VSCode , the only thing is that it relies on SAM i think <https://docs.aws.amazon.com/toolkit-for-vscode/index.html>

<@U01NDPM3NDT> I was debugging the code that was driving the lambda

I can try it out :slightly_smiling_face: my stack is in a monorepo so I don't get the `Run Scripts` from that package, only the root package. Trying to figure out how to write a custom debugger. Once I figure it out I'll post an update :sweat_smile:

i imagine you checked the cloudwatch logs already, right?

<@U01NDPM3NDT> / <@U01RHT7GSD6> recent test of the debugger paused in my Lambda code:

and a watch on the `APIGatewayProxyEventV2` `event`

<@U01RHT7GSD6> if you set the VSCode debugger to `Auto Attach: Smart`, the debugger _should_ run when you run your command in the terminal. My debug session starts when I run `yarn run start`

The only thing is, the timeout will get you. The default timeout is 6 or 10 seconds. So if you pause at a breakpoint the lambda will 500 after that time

nice, I'll try that. I wrote a custom launcher for now and its working :smile:

Indeed it times out super fast, maybe I can just bump the timeout in dev :shrug:

Yea, I mentioned that to <@U01JVDKASAC> - perhaps it'd be nice to set those timeouts to 60s by default with `sst start`

Thanks everyone! This is what I always wanted :smile:  Is there any way I can contribute $ to the project?

Super valuable discussion.. Just opened an issue for extending Function timeout on `sst start` <https://github.com/serverless-stack/serverless-stack/issues/224>

<@U01RHT7GSD6> Appreciate the offer! Just let us know any issues u run up against.. and how we can improve the vscode integration better.. that’d be SUPER helpful!
