Introduction

react-tmap, a high-performance map component library for react based on Tencent Maps and TypeScript encapsulation, has the following features:

• Complete documentation: documentation based on official documentation and framework usage is highly readable, and component examples are complete
• Componentization: Encapsulate the Tencent Maps imperative api as a responsive component, no need to care about the complex map api, only need to operate the data
• Multi-framework: contains react-tmap and vue-tmap, and share the same set of type definitions
• Type-safe(@map-component/tmap-types): supplemented the type declaration of Tencent Maps sdk, components are also developed using TypeScript, a better development experience
• Custom components: provide an open map instance, you can write custom components or directly call the map's native api
• Performance optimization: unify the map api calling method and data monitoring to prevent performance problems caused by misuse of the map api

Simple example

import React, { useState } from 'react';
import { TMap, MultiPolygon } from '@map-component/react-tmap';

const styles = {
  polygon: {
    color: '#3777FF', //surface fill color
    showBorder: false, //whether to show the edge of the pulled face
    borderColor: '#00FFFF', //border color
  },
};

const paths = [
  { lat: 40.041054, lng: 116.272303 },
  { lat: 40.039419, lng: 116.272721 },
  { lat: 40.039764, lng: 116.274824 },
  { lat: 40.041374, lng: 116.274491 },
];

const geometries = [
  {
    id: 'p1', //The unique identifier of the polygon in the layer (required when deleting and updating data)
    styleId: 'polygon', //binding style name
    paths: paths, //polygon outline
  },
];

const center = { lat: 40.041054, lng: 116.272303 };

export default () => {
  const [color, setColor] = useState('#00FF00');
  const [zoom, setZoom] = useState(16);

  const polygonStyles = React.useMemo(
    () => ({
      polygon: {
        ...styles.polygon,
        color,
      },
    }),
    [color],
  );

  return (
    <div>
      <div>
        <button onClick={() => setColor('#00FFFF')}>
          Modify polygon color
        </button>
        <button onClick={() => setZoom(zoom + 1)}>Modify map zoom level</button>
      </div>

      <TMap
        mapKey="TOZBZ-OU2CX-JJP4Z-7FCBV-CDDJ2-AHFQZ" // The applied key
        zoom={zoom}
        center={center} // set the center point coordinates
        control={{
          zoom: { position: 'BOTTOM_RIGHT' },
          scale: false,
          rotate: false,
        }}
      >
        <MultiPolygon
          styles={polygonStyles}
          geometries={geometries}
          onClick={() => console.log('Polygon clicked')} // Click on the polygon
        />
      </TMap>
    </div>
  );
};

mapKey is the newly applied key
