Installation

npm install --save-dev @stackline/types-unist

Preserve existing imports and plugin resolution with an npm alias:

npm install --save-dev @types/unist@npm:@stackline/types-unist

Use the original @types/* alias for automatic TypeScript type discovery and existing compilerOptions.types settings. A scoped-only installation does not automatically expose the original type-package name.

Installation

npm install --save @stackline/types-unist
