nunjucks-prepend

A prepend() filter for nunjucks, the rich and powerful JS template system from Mozilla.

What's it do?

It builds out URL paths. So for instance, you want to type the location of something in your template, then prefix it with you assets directory and your domain:

<link rel="stylesheet" href="{{ "css/myPage.css" | prepend(site.assetsFolder, site.domain) }}">

You can pass it any number of arguments to prepend to the URL. The first passed argument will show up closest to the value you are filtering.

How do I install it?

Attach it to your nunjucks environment using addFilter.

const nunjucks = require('nunjucks'),
    njPrepend = require('nunjucks-prepend');
 
var env = new nunjucks.Environment();
env.addFilter('prepend', njPrepend);
