Similar to pnpm catalog: functionality, yarn has added support for the catalog: protocol https://yarnpkg.com/features/catalogs. In yarn, the catalog configuration is stored in the .yarnrc.yml config file. Examples: ``` // default catalog catalog: lodash: ^4.17.21 // named catalogs catalogs: react18: react: ^18.3.1 react-dom: ^18.3.1 react17: react: ^17.0.2 react-dom: ^17.0.2 ```
