Building with a typescript target fails on the second run

[dancrumb]

Description

The first time I run bob, I get:

 pnpm bob build
ℹ [module] Cleaning up previous build at lib/module
ℹ [typescript] Cleaning up previous build at lib/typescript
ℹ [typescript] Generating type definitions with tsc
⚠ [typescript] Failed to locate tsc in the workspace. Falling back to the binary found in PATH at /Users/dancrumb/Projects/Shoreditch/sutro-2-shoreditch/node_modules/.bin/tsc. Consider adding typescript to your devDependencies or specifying the tsc option for the typescript target.
ℹ [module] Compiling 147 files in src with babel
✔ [module] Wrote files to lib/module
✔ [typescript] Wrote definition files to lib/typescript

If I run it again, immediately, I get:

I did some digging and it appears that the script is trying to write to /Users/dancrumb/Projects/Shoreditch/sutro-2-shoreditch/packages/core-components/lib/typescript/package.json, but /Users/dancrumb/Projects/Shoreditch/sutro-2-shoreditch/packages/core-components/lib/typescript doesn't exist.

That's strange, because it also doesn't exist the first time around

OK - looks like the problem is that it's looking in the wrong place for the tsconfig.tsbuildinfo to delete.

At least on my machine, bob is looking to delete the file from lib/typescript/tsconfig.tsbuildinfo, but it's actually located at lib/tsconfig.tsbuildinfo

That's preventing the second build from happening properly

[dancrumb]

Setting composite to false and incremental to false in my tsconfig file solved the issue for me, but I do believe that this is still a bug in bob

What does your tsconfig.json look like? Is your lib folder ignored in tsconfig.json?

Please link to the full repo.

Hey, I do have the same issue. My tsconfig.json:

// ./tsconfig.json
{
  "compilerOptions": {
    "esModuleInterop": true,
    "jsx": "react-native",
    "lib": ["DOM", "ESNext"],
    "resolveJsonModule": true,
    "skipLibCheck": true,
    "target": "ESNext"
  },
  "exclude": [
    "node_modules",
    "babel.config.js",
    "metro.config.js",
    "jest.config.js"
  ]
}

// ./packages/<package-name>/tsconfig.json
{
  "extends": "../../tsconfig.json",
  "compilerOptions": {
    "rootDir": "src",
    "outDir": "lib",
    "composite": true,
    "allowJs": false,
    "allowUnreachableCode": false,
    "allowUnusedLabels": false,
    "esModuleInterop": true,
    "forceConsistentCasingInFileNames": true,
    "module": "esnext",
    "moduleResolution": "node",
    "noFallthroughCasesInSwitch": true,
    "noImplicitReturns": true,
    "noStrictGenericChecks": false,
    "noUnusedLocals": true,
    "noUnusedParameters": true,
    "noUncheckedIndexedAccess": true,
    "strict": true,
    "types": ["react", "node"]
  },
  "include": ["src"],
  "exclude": ["node_modules", "lib"]
}

What helped was adding:
"tsBuildInfoFile": "./lib/typescript/tsconfig.tsbuildinfo",
to the second json.
Without it my tsconfig.tsbuildinfo is created in lib directory an not in lib/typescript/tsconfig.tsbuildinfo where bob-builder expects it. It should be either documented or fixed to find .tsbuildinfo correctly

I can't link to the full repo as it's a private repo. However, I believe I've done enough debugging that the root cause is identified: the deletion of the tsbuildinfo is brittle and breaks if the file isn't where bob expects it to be.
