installing geojson-vt with Leaflet

Question

I need help using the leaflet plugin geojson-vt. According to tutorials, like this one on http://bl.ocks.org/Sumbera/c67e5551b21c68dc8299, there should be a js file called geojson-vt-dev.js. When I download the zipfile from GitHub I get 6 different js files in the src folder: clip.js, convert.js, index.js, simplify.js, tile.js, wrap.js.

Can anyone help me figure out what I am doing wrong?

This page; http://www.paulcflynn.com/projection_picker.html is ultimately what I am trying to speed by using vector tiles. Loading the GeoJSONs straight in leaflet was fine, but now I need to add more vector files, which reduce performance significantly.

Check out the section named Browser Builds on the GitHub page. It shows you how to use npm to build a development or minified production build.

I just tried npm run build-dev and the output is named geojson-vt-dev.js

Assuming you have git installed, here are the steps:

1. git clone https://github.com/mapbox/geojson-vt.git
2. change into the geojson-vt directory
3. npm install
4. npm run build-dev
