Module Federation Configuration

rsbuildOptions

Additional configuration for the Rsbuild plugin.

target

Tip

Only supported when used as a global plugin in Rslib.

  • Type: 'web' | 'node' | 'dual'
  • Default: 'web'

Used to specify the target runtime environment for the output. When set to dual, it builds both Web (browser) output and Node.js (SSR) output.

After generating SSR output with target: 'dual', you can refer to Create a Modern.js Consumer, create a consumer, and integrate the corresponding Rslib SSR producer for development.

ssr

Deprecated Warning

This option is deprecated. Please use target: 'dual' to enable SSR.

  • Type: boolean
  • Default: false

When enabled, it generates SSR output.
