Build shared .ts files

Hi!

I have shared code in my project, e.g. a folder structure like this: /shared shared1.ts shared2.ts /microservice1 /node_modules package.json microservice1.ts tsconfig.json serverless.yml /microservice2 /node_modules package.json microservice2.ts tsconfig.json serverless.yml

According to what I read it is not possible to pass a YAML file via command line to serverless deploy / offline start. So the current working directory has to be inside "/microservice1" or "/microservice2".

This results in not being able to build with error: 'File '...shared1.ts' is not under 'rootDir' '...microservice1'. 'rootDir' is expected to contain all source files.',

I also can not set rootDir in tsconfig.json to "../" since it is overwritten with default './'. So the only work around I see is to work with symlinks which is IMHO a little hacky.

So is there a possibility to build these shared files?

Is there a solution/workaround for this?

I only found a workaround:

• Install serverless in the root folder of "/shared", "microservice1" and "microservice2"
• in the package.json folder in "microservice1" and "microservice2" I have such a npm script "node ../node_modules/serverless/bin/serverless offline start"

Thanks @joshinator. I considered that path but my project has a backend, frontend, lambdas and shared folder and so I didn't want to corrupt the project by enveloping it with serverless configurations at the root.

The workaround I used was to use yarn link for the shared package and treat it like an independent package. I personally think this is a slightly cleaner approach.

~Unfortunately this only works for sls invoke local but errors out when attempting to run sls package. Looking to see if it can be fixed.~ This didn't work with serverless-plugin-typescript version 1.1.9. Downgrading to version 1.1.7 worked. Related to this issue.
