#BuildCache.buildDependencies property

This API is provided as a beta preview for developers and may change based on feedback that we receive. Do not use this API in a production environment.

An array of files containing build dependencies. Rspack will use the hash of each of these files to invalidate the persistent cache.

Signature:

buildDependencies?: string[] | undefined;

#Default Value

['package.json', 'tsconfig.json' (or source.tsconfigPath), '.env', '.env.*', 'tailwindcss.config.*']; when using the Rspeedy CLI with performance.buildCache enabled, the loaded lynx.config.* file is also added.

#Example

Add postcss.config.js to the build dependencies.

import { defineConfig } from '@lynx-js/rspeedy'

export default defineConfig({
  performance: {
    buildCache: {
      buildDependencies: ['postcss.config.js'],
    },
  },
})
