使用JavaScript编写的模块化地理空间引擎

根据需要打包指定的模块。官方提供参考的步骤如下：

Getting started with Turf.js
|
|
There are a few different ways to get started using Turf, the documentation below will provide a couple of the common scenarios.
|
|
Using directly in the browser
|
|
Load the minified file via a script tag, this will expose a global variable named turf.
|
|
|
<script src='https://npmcdn.com/@turf/turf/turf.min.js'></script>
|
<script>
|
var bbox = turf.bbox(features);
|
</script>
|
|
Note: The full build of Turf weighs around 500kb which is a fair bit of javascript to load so you probably only want to pull in the bits you need, see the instructions below on how to create a custom build.
|
|
Using in Node or with a build tool
|
|
If you're working in Node or with build tool (such as webpack, browserify or rollup) you can include individual turf modules in your project.
|
|
|
// Import your module of interest after you've installed your module
|
const turfCollect = require('@turf/collect');
|
// And then use it
|
turfCollect(points, polys, 'population', 'populationValues')
|
|
Creating custom builds for use in the browser
|
|
Step 1 Create a folder and install whatever modules you are interested in via npm
|
|
|
npm install @turf/collect @turf/buffer
|
|
Step 2 Create a file called main.js in the root directory, in this include your required modules within a modules.exports statement
|
|
|
module.exports = {
|
collect: require('@turf/collect'),
|
buffer: require('@turf/buffer')
|
};
|
|
Step 3 Run the following browserify command
|
|
|
browserify main.js -s turf > outTurf.js
|
|
Done You can now use your outTurf.js file where you want just like you would normally use Turf, eg load it via a script tag and call turf using the turf global variable.
