Simple utilities for modern npm packages.

npm install @sanity/pkg-utils -D

# Initialize a new package
pnpx @sanity/pkg-utils@latest init my-package

# In a Node.js package directory with `package.json` present

# Check the package
pkg-utils check

# Build the package
pkg-utils build

# Watch the package
pkg-utils watch

Run pkg-utils -h for more information on CLI usage.

@sanity/pkg-utils reads most of its configuration from package.json. But sometimes you need more control. You may then add a configuration file named package.config.ts (or .js, .cjs, or .mjs).

// package.config.ts

import {defineConfig} from '@sanity/pkg-utils'

export default defineConfig({
  extract: {
    rules: {
      // do not require internal members to be prefixed with `_`
      'ae-internal-missing-underscore': 'off',
    },
  },

  // the path to the tsconfig file for distributed builds
  tsconfig: 'tsconfig.dist.json',
})
