Couldn't get Serverless to work properly with "Manage routes from code"

[alexdonh]

@Romakita Hey it's me again!

I am experimenting Serverless platform but it got me a little confused. I was following https://tsed.io/tutorials/serverless.html#manage-routes-from-code but I couldn't get "Manage routes from code" to work. Do you have a working example?

Also, I see that serverless-offline plugin is installed but you are running serverless invoke local... Is that intended?

[Romakita]

Hello @alexdonh
I'm sorry, I miss to give a command example to invoke the lambda with a router :/

Add this task on your package.json:

"scripts": {
    "invoke:any": "serverless invoke local -f any --data '{\"path\":\"/timeslots\", \"httpMethod\": \"GET\"}'"
}

See you

[Romakita]

You have to build your code before

[Romakita]

The build task depend on your stack. It's recommended to build lambda with webpack instead of tsc

[alexdonh]

i indeed built with tsc. the thing is i got it working with this

hello:
    handler: dist/handler.hello <==== 
    events:
      - http:
          path: /hello
          method: get

$ tsc --project tsconfig.compile.json
{
    "statusCode": 200,
    "body": "Hello, world!",
    "headers": {
        "x-request-id": "74a3a343-0161-4cae-969c-fc743028fab2"
    },
    "isBase64Encoded": false
}
✨  Done in 4.24s.

but not this

any:
    handler: dist/handler.handler
    events:
      - http:
          method: ANY
          path: /
      - http:
          method: ANY
          path: '{proxy+}'

in handler.ts, do i need to do something about export = platform.callbacks() as it looks like the callbacks() return a list of functions exported from the lambdas.

[Romakita]

Again, I'm sorry, I completly forgot to add the right example for the router mode.

You want to use the router only:

import {PlatformServerless} from "@tsed/platform-serverless";
import {TimeslotsLambda} from "./TimeslotsLambda";

const platform = PlatformServerless.bootstrap({
  lambda: [TimeslotsLambda]
});

export const handler = platform.handler();

Mixed mode:

import {PlatformServerless} from "@tsed/platform-serverless";
import {TimeslotsLambda} from "./TimeslotsLambda";

const platform = PlatformServerless.bootstrap({
  lambda: [TimeslotsLambda]
});

const callbacks = platform.callbacks();
callbacks.handler = platform.handler();
export = callbacks;

See you

Managed to make it work!! I had to go with mixed mode, the router-only mode didnt work on my end. Thanks a lot @Romakita
