Install dependencies with yarn.

yarn

Run TypeScript for all packages in watch mode using yarn dev or a specific package using the filter flag, e.g., yarn dev --filter logging. Additional scripts for testing, linting, and building can be found in package.json.

We use Turborepo's code generation to create new packages. Run the following command, provide it with information, and it will create a package with some default scripts and TypeScript configured.

yarn generate:package

We use Yarn workspaces. To install a dependency to a specific workspace (package) use, for instance, yarn workspace @sebspark/logging add @types/jest. Note that the workspace name is the name defined in package.json, not the folder name.
