Hmm, I'm toying around with using SST in a monorep...

Hmm, I'm toying around with using SST in a monorepo and I think I'd like to try this approach:

apps

services

packages

and

infra

. Each "service" should have its package.json

"main"

point to an exported stack, which may take dependencies as props. Each app (there will be two really, web and mobile app) similarly exports a "main" which is a stack (well a mobile app doesn't, a web one does). Packages are libraries, their

main

points to the library entrypoint, and should be usable from any of the frontends or backends (shared types, configs, validations go here).

infra

basically contains the main SST index which ties the services and front ends together. Thoughts? 😅

So far its actually not looking bad at all, though some explicit path passing needs to happen (e.g.

--path

in sst-env and some other pre-resolved paths with

require.resolve

)

one bit to really make this neat is (I believe someone mentioned it somewhere)

--wait

in sst-env, which would let turborepo run

dev

in parallel in the infra and (web) app (or infra + mobile app)

to clarify on require.resolve, it looks something like this

const moduleDir = path.dirname(require.resolve("@prject/service-name/package.json"))

- and then this is used to pass

srcPath

🙂

Any chance you can please share a sample open source repo of this set up? Looks like a good idea and set up to me.

Yep I was thinking of making a template after everything is smooth

currently debating whether to instead go with a flat package structure and have 2 packages per app/service, app and

app-infra

the stack-in-the-app approach seems to work, but I worry local app specific tsconfig / eslint / etc could interfere if present

had to go with a separate pkg for the stack that is pre-built with tsc. this is due to esbuild building a JS file that isn't able to

require

the typescript file outside of dev mode. Still think its turning out pretty clean so far. Will update once its ready.

@Gjorgji Kjosev I've been using lerna, ts, monorepo with sst. My starting point was this repo, i think it's good starting point and I added sst stack to it: https://github.com/mike-north/js-ts-monorepos/tree/solution I've gone for

packages

scripts

stacks

at root with lerna.
