prop-types dependencies

[TripleJBlog]

This library requires prop-types dependency extracted from the built-in React v15.5.0.

Please include prop-types in project or remove the dependency so that users don't have to find dependencies.

I'm still having this issue with a clean install of vite and react-simple-maps. After installing prop-types, the below error was resolved.

✘ [ERROR] Could not resolve "prop-types"

    node_modules/react-simple-maps/dist/index.es.js:2:22:
      2 │ import PropTypes from 'prop-types';
        ╵                       ~~~~~~~~~~~~

  You can mark the path "prop-types" as external to exclude it from the bundle, which will remove
  this error.

Reproduction

1. Create a react project with vite:

   yarn create vite missing-dependency-example --template react-swc-ts && \
   cd missing-dependency-example && \
   yarn add react-simple-maps@3.0.0 && \
   yarn add @types/react-simple-maps && \
   yarn install

2. Replace App.tsx with the (slightly modified) example:

   
   import React from 'react';

import { ComposableMap, Geographies, Geography } from 'react-simple-maps';

const geoUrl = "https://raw.githubusercontent.com/deldersveld/topojson/master/world-countries.json";

const MapChart = () => { return (

{({ geographies }) => geographies.map((geo) => ( )) }

) }

const App = () => { return (

) } export default App; ```` 3. Run to see error ```` yarn run dev ````
