NestJS in nx workspace as an Azure function about nx-plugins

Ok figured out that the problem was just a wrong runtime version of node on azure :) so ncc is working amazingly! I will go for it

First thing we need is a builder, becasue

• azure functions require js files per function
• all available builders create a single bundle

I have manually configured an nx app (based on @nrwl/node that contains an azure function project which builds fine. But without the ability to output multiple files when building we would only able to create a single function per project :)

I'm no expert in webpack but looking at:

• the current node webpack config
• and this article

It looks doable without major surgery. That said I never build an angular builder :)

After getting azure functions to build the next would be to tackle:

• schematic for creating an azure function app
• schematic for adding new function

After that one can look creating schematics for specific apps like nest.

Update:

• this following azure function webpack plugin looks promising. Its based on the previously azure-fucntion-pack package which is no longer maintained
  • it scans the entry directory for functions.json files and uses those to build the individual functions
• we would also need to resolve tsconfig patsh properly, luckily there seems to be a very well supported webpack plugin for handling that

Thanks a lot for all the input! I will try to check how I can fit it into this project! But let's start with small steps. So the first thing we should do is to be able to deploy a nestjs app with 1 function. then we can go ahead with splitting into multiple functions.

I know from Kamil they are working on a feature there where you can set separate functions via decorator on modules. Hope this lands soon to nestjs

Not easy to integrate it as easy as possible :(

2 options are there:

1. you need to maintain a separate package.json with all the dependencies for the node / nest app
2. Find a way to automatically align all required dependencies. Here I am trying at the moment this package: https://github.com/zeit/ncc but seems not to work. Trying still to make a workable solution with it.
