Scaffold a new workspace (app or package) in this Turborepo monorepo.

Gather Requirements

Ask the user (if not already specified):

1. Type: Is this an app (apps/) or a package (packages/)?
2. Name: What should it be called? (will be prefixed with @repo/)
3. Description: One-line description of what it does.

If not specified, use these defaults:

• Apps extend @repo/typescript-configuration/server.json
• Packages extend @repo/typescript-configuration/library.json
• All workspaces use oxlint for linting with type-aware mode

Scaffold the Workspace

For a package (internal, no build step)

Create the following files:

packages/<name>/package.json:

• name: @repo/<name>
• private: true
• version: "0.0.1"
• type: "module"
• exports: { ".": "./src/index.ts" } (Just-in-Time pattern -- no build)
• scripts: lint, lint:fix, test, typecheck (no build script)
• devDependencies: @repo/typescript-configuration (workspace:*), @types/bun, oxlint

packages/<name>/tsconfig.json:

• Extends @repo/typescript-configuration/library.json
• Sets rootDir, paths, include, exclude

packages/<name>/src/index.ts: Empty export placeholder. packages/<name>/src/index.test.ts: Basic test verifying test environment works.

For an app

Create the following files:

apps/<name>/package.json:

• name: @repo/<name>
• private: true
• version: "0.0.1"
• type: "module"
• scripts: build, clean, dev, lint, lint:fix, start, test, typecheck
• devDependencies: @repo/typescript-configuration (workspace:*), @types/bun, oxlint

apps/<name>/tsconfig.json:

• Extends @repo/typescript-configuration/server.json
• Sets rootDir, paths, include, exclude

apps/<name>/bunfig.toml: Copy from root bunfig.toml. apps/<name>/src/index.ts: Entry point placeholder. apps/<name>/src/index.test.ts: Basic test placeholder.

If the app needs a build step, also create:

• apps/<name>/tsconfig.build.json (extends local tsconfig)
• apps/<name>/scripts/build.ts (using Bun.build)

After Scaffolding

1. Run bun install to link the new workspace.
2. Run bun run typecheck to verify TypeScript resolves.
3. Run bun run test to verify tests pass.
4. Report what was created.
