How to include ts-topojson into Angular2 app?

How would I import ts-topojson into an Angular2 project so I get Typescript typings? I installed the module using npm and tried to include with a simple import statement but the linter said it couldn't find 'topojson'.

import { Topojson } from 'topojson';

This is my first Angular2 project so I'm very new at this so I could possibly be missing a crucial step.

Solution

  • You could install the package @types/topojson with npm install @types/topojson --save-dev.

    Now you can use topojson the following way within a component:

    import {topology, feature, ...} from 'topojson';

    Or with:

    import * as t from '@types/topojson';
