Nx comes with dedicated documentation for each framework:

@nrwl/next:build

Options can be configured in workspace.json when defining the executor, or when invoking it. Read more about how to configure targets and executors here: https://nx.dev/core-concepts/configuration#targets.

Type: string

The output path of the generated files.

root (required)

Type: string

The source root

buildLibsFromSource

Default: true

Type: boolean

Read buildable libraries from source instead of building them separately.

fileReplacements

with

Type: string

The file to replace with.

nextConfig

Path (relative to workspace root) to a function which takes phase, config, and builder options, and returns the resulting config. This is an advanced option and should not be used with a normal Next.js config file (i.e. next.config.js).
