tsc: Referenced project must have setting "composite": true.

[JedBeom]

Library Affected:
All workbox libraries referencing other workbox libraries

Typescript Version:
5.7.3

I use workbox-precaching for my project. However I've got these messages from VS Code:

Referenced project '/path/to/node_modules/workbox-core' must have setting "composite": true.

Referenced project '/path/to/node_modules/workbox-routing' must have setting "composite": true.

Referenced project '/path/to/node_modules/workbox-strategies' must have setting "composite": true.

According to the TypeScript Handbook, referenced projects must have the new composite setting enabled.

It seems the libraries below referenced by other libraries:

1. workbox-background-sync
2. workbox-broadcast-update
3. workbox-build
4. workbox-cacheable-response
5. workbox-core
6. workbox-expiration
7. workbox-google-analytics
8. workbox-routing
9. workbox-strategies

Adding "composite": true to each tsconfig.json would fix these warnings.

@JedBeom I opened #3402 to address this.

How are you using workbox-precaching in your project? Can you provide a sample to reproduce this issue?

And how did you determine which packages (libraries) referenced other packages?

[JedBeom]

@westonruter I made a sample repository: https://github.com/JedBeom/workbox-composite-demo

I checked each packages/*/tsconfig.json to find which packages are referenced by other packages, like:

workbox/packages/workbox-build/tsconfig.json

Lines 14 to 21 in f05c571

	"references": [
	{"path": "../workbox-background-sync/"},
	{"path": "../workbox-broadcast-update/"},
	{"path": "../workbox-cacheable-response/"},
	{"path": "../workbox-core/"},
	{"path": "../workbox-expiration/"},
	{"path": "../workbox-google-analytics/"}
	]

workbox/packages/workbox-precaching/tsconfig.json

Lines 9 to 13 in f05c571

	"references": [
	{"path": "../workbox-core/"},
	{"path": "../workbox-routing/"},
	{"path": "../workbox-strategies/"}
	]

workbox/packages/workbox-webpack-plugin/tsconfig.json

Line 13 in f05c571

"references": [{"path": "../workbox-build/"}]

Any updates for this?

@JedBeom are you able to confirm whether #3402 fixes the issue?
