Deploy multiple TypeScript functions to Google Cloud

How can I build and deploy multiple TS cloud functions from the same codebase?

I'm following your TS guide which focuses on the single function use case -> [docs/typescript.md](https://github.com/GoogleCloudPlatform/functions-framework-nodejs/blob/main/docs/typescript.md)

Project structure :

Deploy command :

`gcloud functions deploy catalogUpdateFunction \
--gen2 \
--region=europe-north1 \
--runtime=nodejs22 \
--source=. \
--entry-point=catalogUpdateFunction \
--trigger-http
`

Open questions:

1. What should be the value of the main field in package.json ?
2. What should the source be for the deploy command?

Setting the source value to ` --source=./build/functions \` fails with the following error: `ERROR: (gcloud.functions.deploy) Invalid value for [--source]: Provided source directory does not have file [package.json] which is required for [nodejs22]. Did you specify the right source?`

Comienza con docs/typescript.md y con la estructura de package.json y build/functions descrita en la issue. Verifica el directorio de código fuente esperado y el campo main para desplegar varias funciones de Node.js 22; después, documenta un proceso de despliegue de varias funciones que funcione, responda a ambas preguntas y aborde el error indicado de que falta package.json.
