将 BeautifyMarker 插件添加到 ngx-leaflet 项目中

Question

我目前无法将 BeautifyMarker 插件与 ngx-leaflet Angular 2 包集成。

我已经关注了 install instructions for BeautifyMarker alongside the ngx-leaflet plugin instructions，但没有成功。

我使用 npm install 获取 BeautifyMarker、Font Awesome，并且已经安装了 Bootstrap。 Leaflet 也已根据 ngx-leaflet 官方教程正确添加和配置。

我编辑了 angular-cli.json 文件以包含 BeautyMarker .css 和 .js 文件，如下所示：

"styles": [
    "styles.css",
    "../node_modules/leaflet/dist/leaflet.css",
    "../node_modules/font-awesome/css/font-awesome.css",
    "../node_modules/bootstrap/dist/css/bootstrap.css",
    "../node_modules/beautifymarker/leaflet-beautify-marker-icon.css"
],
"scripts": [
    "../node_modules/leaflet/dist/leaflet.js",
    "../node_modules/beautifymarker/leaflet-beautify-marker-icon.js",
], ...

我还完全导入了包，因为它扩展了 L，像这样：

import * as L from 'leaflet';
import 'beautifymarker';

那不行，所以我也试了：

import * as L from 'leaflet';
import '../../node_modules/beautifymarker/leaflet-beautify-marker-icon.js';

还尝试完全省略导入，就像 heatmap.js 插件一样。 None 个允许我访问 L.BeautifyIcon。

有什么建议吗？

我花了一些时间来调查您的问题。

我所做的是：

已安装传单，@asymmetrik/ngx-leaflet & @types/leaflet
已安装 bootstrap、font-awesome、beautifymarker 并将它们添加到 angular.json
重新启动服务器，因为观察者仅针对 src 文件夹，angular-cli.json 未观察到渲染 font-awesome

angular.json

"styles": [
   "node_modules/leaflet/dist/leaflet.css",
   "node_modules/bootstrap/dist/css/bootstrap.css",
   "node_modules/font-awesome/css/font-awesome.css",
   "node_modules/beautifymarker/leaflet-beautify-marker-icon.css",
   "src/styles.css"
],
"scripts": [
    "node_modules/leaflet/dist/leaflet.js",
    "node_modules/beautifymarker/leaflet-beautify-marker-icon.js"
]

app.module.ts

import { LeafletModule } from '@asymmetrik/ngx-leaflet';
..
imports: [
   ..,
   LeafletModule.forRoot()
],

app.component.ts

// import * as L from 'leaflet';
// import 'beautifymarker';

// instead of the above try
import 'leaflet';
import 'beautifymarker';
declare let L;

options = {
    layers: [
        L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
            maxZoom: 18, attribution: '...' }
        )
    ],
    zoom: 12,
    center: L.latLng(46.879966, -121.726909)
};

beautifyOptions = {
    icon: 'plane',
    borderColor: '#8D208B',
    textColor: '#8D208B',
    backgroundColor: 'transparent'
};

layers = [
    L.marker([ 46.879966, -121.726909 ], {
        icon: L.BeautifyIcon.icon(this.beautifyOptions)
    })
];

模板

<div style="height: 500px;"
    leaflet 
    [leafletOptions]="options"
    [leafletLayers]="layers">
</div>
