Esri Leaflet Browserify Example

Example of using Leaflet and Esri Leaflet with Browserify!

  1. Install Browserify npm install -g browserify
  2. Fork and clone this repo
  3. cd into esri-leaflet-browserify-example
  4. Install dependencies with npm install
  5. Run browserify app.js -o app-built.js
  6. Open index.html in your browser.

Smaller Builds Using the Esri Leaflet Bundler

This sample includes 2 modules from Esri Leaflet:

  • featureLayer
  • basemapLayer

and 3 modules from Esri Leaflet Geocoder:

  • geosearch
  • arcgisOnlineProvider
  • featureLayerProvider

You can create a custom build that includes all of these modules with the Esri Leaflet Bundler. This will reduce the size of your build to from 118.69 kB (minified + gzipped) to 55.18 kB (minified + gzipped), an 46% reduction. This is because Leaflet will be included 3 time once in the app, once for Esri Leaflet and once for Esri Leaflet Geocoder.

Then create a file called esri-leaflet-custom-build.js with the following contents:

import {
} from 'esri-leaflet';

import {
} from 'esri-leaflet-geocoder';

export default {
  featureLayer: featureLayer,
  basemapLayer: basemapLayer,
  geosearch: geosearch,
  arcgisOnlineProvider: arcgisOnlineProvider,
  featureLayerProvider: featureLayerProvider

Note that since will will compile this to ES 6 modules we can export not just the default export but exports for each individual module.

Then run esri-leaflet-bundler esri-leaflet-custom-build.js -o esri-leaflet-custom.js --sourcemap inline --format cjs to generate your custom build.

Then replace the references to esri-leaflet and esri-leaflet geocoder in your in main.js with references to your custom build:

var esri = require('./esri-leaflet-custom');
var geocoding = require('./esri-leaflet-custom');
