This was a latent issue due to a confluence of things: - we don't explicitly do type checking in this repo - instead we rely implicitly on the fact that we use tsup in part to build `.dts` files, which performs type checking - but tsup type checking behaves slightly differently than just running `tsc` in various little ways, largely because it's scoped per entrypoint - we weren't setting `skipLibCheck: true` in the `tsconfig.json`, which seemed reasonable as there were no errors inside `node_modules/` - now when I went to set up vitest type tests, this started type checking some stuff under the hood, and this failed with type errors inside `node_modules/`, despite it using our `tsconfig.json` - it turns out this is because the tsup type checking approach was not encountering these errors; you can confirm this by running `npx --package=typescript tsc --noEmit` in `packages/functions/` So, TL;DR: we had a latent necessity for `skipLibCheck` obscured by our weird implicit type checking via `tsup --dts`. --- packages/functions/tsconfig.json | 1 + 1 file changed, 1 insertion(+) diff --git a/packages/functions/tsconfig.json b/packages/functions/tsconfig.json index 12ec691d..49490e9d 100644 --- a/packages/functions/tsconfig.json +++ b/packages/functions/tsconfig.json @@ -11,6 +11,7 @@ "removeComments": false, "strict": true, "moduleResolution": "node", + "skipLibCheck": true, "forceConsistentCasingInFileNames": true }, "include": ["src", "dev"]
