I managed to get Leaflet working with Angular 2 and Webpack by following this project.
angular 2 leaflet starter
I can see the typings configured in "browser.d.ts":
/// <reference path="browser\ambient\leaflet\leaflet.d.ts" />
webpack.config.js defines an entry point:
... entry: { 'polyfills': './src/polyfills.ts', 'libs': './src/libs.ts', 'main': './src/main.ts' }, ...
The "libs.ts" contains the import of the Leaflet module:
import 'leaflet';
I'm using Atom as a code editor. It now recognises all the Leaflet classes and methods. I can now do things like this in Angular 2:
import {Map, TileLayer} from 'leaflet'; ... this.baseMaps = { StreetMap: new TileLayer('mapbox.streets') };
Here is where my problems start. I'm trying to use mapbox.js. What I did was I installed mapbox.js library and typings:
npm install mapbox.js --save typings install mapbox --save
This is where I'm stuck. For the life of me I can't figure out how to do what Leaflet managed to do.
import 'mapbox';
Doesn't work.
ERROR in ./src/libs.ts Module not found: Error: Cannot resolve module 'mapbox' in C:\Develop\angular2-webpack-starter\src @ ./src/libs.ts 3:0-17
I can see "browser.d.ts" has the following:
/// <reference path="browser\ambient\leaflet\leaflet.d.ts" /> /// <reference path="browser\ambient\mapbox\mapbox.d.ts" />
I thought maybe Mapbox will just work, because it extends the Leaflet library?
It seems that I can basically do something like this, which is the standard javascript way:
this.baseMaps = { StreetMap: L.mapbox.tileLayer('mapbox.streets') };
But not this:
this.baseMaps = { StreetMap: new TileLayer('mapbox.streets') };
This obviously doesn't work either:
import {Map, TileLayer} from 'mapbox';
What am I doing wrong?
回答1:
You can just use the mapbox.js NPM module, and it'll include everything you need.
npm install mapbox.js --save
See this example. We're using Webpack to do the module loading, and with TypeScript you need to explicitly import * for untyped modules.
import * as L from 'mapbox.js'; const map = L.mapbox.map('mapContainer', 'mapbox.streets'); // do stuff.

For anyone like me who just wanted to get a map to show in their project, here's how I got it. Based mostly on Angular2 Mapbox-gl Starter.
Adding Mapbox-gl to Angular 2 - Webpack and Typescript
Install the needed packages...
npm install mapbox-gl --save
npm install @types/mapbox-gl --save
npm install @types/geojson --save
Add stuff to webpack...
module.exports = function(options) { return { resolve: { alias: { 'mapbox-gl': '../node_modules/mapbox-gl/dist/mapbox-gl.js' } }, module: { postLoaders: [ { include: /node_modules\/mapbox-gl-shaders/, loader: 'transform', query: 'brfs' } ] } } }
Add a map.service.ts (For some reason I had to use full relative paths in the imports)...
import { Injectable } from '@angular/core'; import * as mapboxgl from '../../../../node_modules/mapbox-gl/dist/mapbox-gl.js'; import { Map } from '../../../../node_modules/mapbox-gl/dist/mapbox-gl.js'; @Injectable() export class MapService { map: Map<any, any>; constructor() { (mapboxgl as any).accessToken = 'YOUR_MAPBOX_TOKEN_HERE'; } }
Add maps to your component...
import { Component } from '@angular/core'; import { MapService } from '../../api/resources/map.service'; import { Map } from '../../../../node_modules/mapbox-gl/dist/mapbox-gl.js'; @Component({ selector: 'my-component', styles: [ require('./my-component.component.less') ], template: require('./my-component.component.html'), providers: [ MapService ] }) export class MyComponentComponent { constructor(private mapService: MapService) { } ngOnInit() { let map = new Map({ container: 'map', style: 'mapbox://styles/mapbox/light-v9', zoom: 5, center: [-78.880453, 42.897852] }); this.mapService.map = map; } }
Add map div to your html...
// my-component.component.html <div id="map" class="mapboxgl-map"></div>
For styles, I use LESS, so I imported the mapbox styles there...
// my-component.component.less @import (less) '../../../../node_modules/mapbox-gl/dist/mapbox-gl.css';
