About

VS Code uses TypeScript type declaration (typings) files (for example node.d.ts) to provide metadata to VS Code about the JavaScript based frameworks you are consuming in your application.

Installation

Installation:

  • VsCode: VS Code will install them automatically for you (Thanks to the Automatic Type Acquisition (ATA). ATA pulls down the npm Type Declaration files (*.d.ts) for the npm modules referenced in the package.json.
  • Manually
npm install --save-dev @types/d3-sankey
