handlebars-helper-sri

Install

npm install --save handlebars-helper-sri

Usage

Attach the helper to handlebars:

var handlebars = require("handlebars");

handlebars = require("handlebars-helper-sri").register(handlebars);

Then, call the helper from your Handlebars template:

<script src="/script.js" integrity="{{sri "./public/script.js"}}"></script>
<link href="/style.css" integrity="{{sri "./public/style.css"}}" rel="stylesheet">

Caching

You may wish to attach a custom subresource instance, for pre-load caching:

var handlebars = require("handlebars");
var subresource = require("subresource");

[
    "../public/script.js",
    "../public/style.css"
].forEach(subresource);

handlebars = require("handlebars-helper-sri").register(handlebars, subresource);
