dustjs: proposal for the persistent storage of compiled templates

intro.js

var dust = require('dustjs-linkedin');

//whitespaces added for clarification
module.exports = (function(){
    dust.register("intro",body_0);

    function body_0(chk,ctx){
        return chk.write("Hello ").reference(ctx._get(false, ["name"]),ctx,"h").write("!");
    }

    return body_0;
})();

readTemplateFromDiskAndRender.js

var dust = require('dustjs-linkedin');

var templateName = 'intro';

var serializedTemplate = require('./' + templateName);

function createCallableTemplate(name, tmpl) {
    return function(context, callback) {
        var master = callback ? new dust.Stub(callback) : new dust.Stream();
        dust.nextTick(function() {
            if(typeof tmpl === 'function') {
                tmpl(master.head, dust.Context.wrap(context, name)).end();
            }
            else {
                dust.onError(new Error('Template [' + name + '] cannot be resolved to a Dust function'));
            }
        });
        return master;
    };
}

var usableTemplate = createCallableTemplate(templateName, serializedTemplate);

usableTemplate({name:'fooooo'}, function(error, result) {
    console.log(result);
});
