I’m running into a weird tsconfig issue (related to what we just talked about w/ restructuring the project, @thdxr) in my

src/lambda

folder (which is a workspace/subpackage), I have this tsconfig:

Copy code

{
  "extends": "../../tsconfig.json",
  "compilerOptions": {
    "baseUrl": ".",
    "paths": {
      "$core/*": ["../core/*"],
      "$libs/*": ["./libs/*"],
      "$types/*": ["./types/*"]
    },
  }
}

this works perfectly fine, so anywhere in lambda/* I can do

import { blah } from '$libs/whatever'

. at least, VS Code says it’s fine and it resolves.. but when I do `yarn build`:

Copy code

src/lambda/graphql/mutations/update-transcoding-status.ts:2:31 - error TS2307: Cannot find module '$libs/db' or its corresponding type declarations.

2 import { dataApi, knex } from '$libs/db';

how do I resolve this?

basically it seems like

yarn build

is ignoring the fact that

src/lambda

has its own tsconfig and is telling how to resolve path aliases

for now, I just added this to the root level tsconfig, though this isn’t ideal since paths have to be maintained in two places

Copy code

"$core/*": ["src/core/*"],
      "$libs/*": ["src/lambda/libs/*"],
      "$types/*": ["src/lambda/types/*"]

running yarn build in root?

yeppers

yarn build/start/deploy

etc

thdxr

08/19/2021, 9:52 PM

tsconfig is unaware of yarn workspaces, it has its own thing called

references

thdxr

08/19/2021, 9:52 PM

that maybe is the issue

thdxr

08/19/2021, 9:53 PM

any reason you're running yarn build in root?

Sam Hulick

08/19/2021, 9:55 PM

isn’t that where it’s supposed to be? at root level is sst.json pointing to the entry file

infra/index.ts

Sam Hulick

08/19/2021, 9:56 PM

that’s what the docs say to do

thdxr

08/19/2021, 9:59 PM

Ah, but the root tsconfig shouldn't include anything but

infra

Sam Hulick

ahhhhh

Sam Hulick

08/19/2021, 10:00 PM

of course. the default tsconfig in new SST projects isn’t meant for monorepos. makes sense

omg man, it finally built 🙌

Copy code

Successfully compiled 3 stacks to .build/cdk.out:

  dev-microservices-core
  dev-microservices-api

is it normal to have all thees

.build

folders? only

src/lambda

is ever used as a

srcPath

Copy code

./src/lambda/.build
./src/lambda/auth/.build
./src/lambda/graphql/.build
./src/lambda/media-processor/.build
./src/lambda/rest/.build

are those leftover from before maybe?

Sam Hulick

08/19/2021, 10:12 PM

I don’t think so. I’m deploying now ,but afterwards I’ll remove those & do a

yarn build

and see if they show up

Sam Hulick

08/19/2021, 10:13 PM

they might be from before

Sam Hulick

08/19/2021, 10:20 PM

yyyep! just leftovers. now when I build, I just get

.build

and

src/lambda/.build
