@sanity/tsconfig

Shared tsconfig.json presets following best practices at Sanity.io

Installation

Add the package to your "devDependencies":

npm install --save-dev @sanity/tsconfig
# or
pnpm add --save-dev @sanity/tsconfig
# or
yarn add --dev @sanity/tsconfig

Usage

Choose one of the presets as your base:

• @sanity/tsconfig/recommended
• @sanity/tsconfig/strict
• @sanity/tsconfig/strictest

You can optionally combine your base with @sanity/tsconfig/isolated-declarations if you're using build tools (like rolldown or tsdown) that can generate .d.ts files significantly faster when TypeScript is constrained with "isolatedDeclarations": true.

Recommended tsconfig.json

Add to your tsconfig.json:

{
  "extends": "@sanity/tsconfig/recommended"
}

Strict tsconfig.json

Add to your tsconfig.json:

{
  "extends": "@sanity/tsconfig/strict"
}

Strictest tsconfig.json

Add to your tsconfig.json:

{
  "extends": "@sanity/tsconfig/strictest"
}

Isolated Declarations tsconfig.json

Extend the isolated-declarations.json preset in addition to your base. If your tsconfig.json previously looked like this:

{
  "extends": "@sanity/tsconfig/strict"
}

Then change extends to an array and isolated-declarations to the end:

{
  "extends": ["@sanity/tsconfig/strict", "@sanity/tsconfig/isolated-declarations"]
}
