TypeScript compile fails

[gflohr]

I can no longer build a package depending on valibot version 0.32.0 or 0.31.0. Downgrading to 0.30.0 fixes the issue.

index.ts:

import * as v from 'valibot';
console.log(v.object({}));

package.json:

{
  "name": "valibot-build",
  "scripts": {
    "build": "rm -rf dist; tsc"
  },
  "dependencies": {
    "valibot": "^0.32.0"
  },
  "devDependencies": {
    "typescript": "^5.4.5"
  }
}

tsconfig.json:

{
	"compilerOptions": {
		"allowSyntheticDefaultImports": true,
		"noImplicitAny": true,
		"noImplicitReturns": true,
		"noImplicitThis": true,
		"removeComments": true,
		"declaration": true,
		"target": "ES2017",
		"lib": ["ES2017", "dom"],
		"module": "CommonJS",
		"sourceMap": true,
		"typeRoots": ["node_modules/@types"],
		"esModuleInterop": true,
		"moduleResolution": "node",
		"strictNullChecks": true,
		"strictBindCallApply": true,
		"forceConsistentCasingInFileNames": true,
		"noFallthroughCasesInSwitch": true,
		"outDir": "dist",
		"resolveJsonModule": true
	},
	"exclude": ["node_modules"],
}

I have played around with the tsconfig.json but to no avail. The build fails:

$ npm run build

> build
> rm -rf dist; tsc

Found 5 errors in the same file, starting at: node_modules/valibot/dist/index.d.ts:5678

Does the skipLibCheck option solves the problem? https://www.typescriptlang.org/tsconfig/#skipLibCheck

[gflohr]

Yes, setting skipLibCheck to true resolves the issue for me, thank you! Feel free to close the issue.

[fabian-hiller]

I will add it to our docs first! Thanks for bringing this up!

[threehams]

Adding skipLibCheck isn't really a fix, since it skips checking on all .d.ts files across the whole project. This can result in any leaking out, since they are legitimate errors.

does not satisfy the constraint errors are usually pretty simple to fix, I can take a look now.

[fabian-hiller]

Feel free to have a look. 🙌

[carcinocron]

just use skipLibCheck

that would be like if zod devs responded to "Why is zod 100kb" with "just use gzip".

I'm currently using tsc-silent, to work around this issue, here's my current hall of shame.

tsc-silent -p ./tsconfig.json --suppress @/node_modules/solid-start/ --suppress @/node_modules/@rollup/ --suppress @/node_modules/valibot/dist/index.d.ts

[fabian-hiller]

This will probably be fixed in the next version.

[fabian-hiller]

v0.38.0 is available 🚀
