Yarn Workspaces

Yarn was the first package manager built specifically around workspaces. `yarn workspace`, `yarn workspaces foreach`, `yarn workspaces focus`, and `yarn workspaces list` provide first-class monorepo coordination — running commands inside a specific workspace, fanning out commands across all workspaces, installing a single workspace and its dependencies, and listing the workspace tree.

Yarn Workspaces is one of 10 APIs that Yarn publishes on the APIs.io network.

This API exposes 1 JSON Schema definition.

Tagged areas include Workspaces, Monorepo, JavaScript, and Package Manager. The published artifact set on APIs.io includes API documentation and 1 JSON Schema.
