Is this plugin compatible when using multiple runtimes?

[riltsken]

Heya. First off just wanted to say this plugin made my life a whole lot easier by not dealing with compilation configuration :)

The current issue I am running into is that I wanted to add a python lambda alongside my typescript lambdas. Regardless of my tsconfig / serverless.yml I can't seem to prevent serverless-plugin-typescript from trying to compile my python functions.

If you think this is NOT an issue with serverless-plugin-typescript I am happy to investigate more, but my current understanding is that this seems to be the culprit since I don't expect it to be jumping into my non-typescript folders.

If you think this is an issue that is easily fixable I am happy to dive in, but I just wanted to make sure I wasn't missing something and any direction you might provide before I do so.

My current layout is the following

 \_funcs
   \_geocode
   \_queue
 \_funcs_python
   \_logentries
 \_serverless.yml
 \_tsconfig.json

stumbled into the same issue when trying to use two runtimes, any updates or solutions/workarounds?

[riltsken]

I did not solve this issue or find a workaround. At some point I was planning on compiling manually to avoid this issue, but just haven't had a big need to do it. Still think this lib is the bees knees if not using multiple runtimes :)

[liam-betsworth]

Also ran into the same issue. Exclude doesn't seem to do anything.

[ACollectionOfAtoms]

Running into the same issue! I think this issue prevents usage of: https://github.com/svdgraaf/serverless-basic-authentication as it requires some python

[Jordan-Eckowitz]

Same issue here. When trying to run serverless-offline it crashes for python lambda functions as its looking for .js or .ts file extensions.

[bobzoller]

super ugly hack, but just because there is no workaround listed here yet...

patch dist/src/index.js with this:

--- index.js.orig       2021-01-18 10:54:23.000000000 -1000
+++ index.js.new        2021-01-18 10:54:57.000000000 -1000

-        return service.functions;
+        return Object.keys(service.functions).reduce(function (memo, k) { if (service.functions[k].typescript !== false) memo[k] = service.functions[k]; }, {});
     }
     get rootFileNames() {
         return typescript.extractFileNames(this.originalServicePath, this.serverless.service.provider.name, this.functions);

and then add typescript: false to any function that isn't Typescript. (you'll see a warning about an unknown property)

[serp-ya]

@bobzoller thanks a lot for the hack! Thanks to your comment I found how to avoid this problem without any changes of the node_modules files.

TS compiling successfully done if I creates a same name .ts file near the Python handler.

It means, I have a function config in the serverles.yml:

functions:
  prepare-data:
    name: prepare-data
    handler: functions/prepare-data/src/handler.convert_data
    runtime: python3.6

And two files

Python:

# functions/prepare-data/src/handler.py
def convert_data(event, context):
    print('Hello Python!!1')

    return 0

TS:

// functions/prepare-data/src/handler.ts
// empty file

And it helps to avoid the compilation failture

[Cittadini]

Hi @serp-ya and @bobzoller , with your hack TS compiling successfully, but lambda contains only js file. Is there a setting for maintain the py file?

Thanks, Andrea

[serp-ya]

@Cittadini I'm not sure why it happened on your side but my lambda works fine with python code... Above I shown a my Lambda configs and it contains important line runtime: python3.6 and I have a global config provider.runtime: nodejs12.x in `serverless.yml too.

I hope it will helps you.

P.S. And not forget to describe what is a function will need to use for a Lambda deploy. I use a converter_data here =>handler: functions/prepare-data/src/handler.convert_data

[Cittadini]

Hi @serp-ya thanks for your tips. I have a config like yours. Maybe I have a plugin that remove the py files: I hope to find it!

Thanks, Andrea

This is fixed now in master, fixed by PR #277

[ScopeSV]

I ran into the error Error: Typescript compilation failed. Please ensure handlers exists with ext .ts or .js when trying to use both JS/TS and Go handlers.

I was using v2.1.2 Upgrading to v2.1.4 solved it for me.
