È possibile precompilare nel client di browser, come ha affermato Thomas Bartelmess.
Si può anche precompilare usando manubrio tramite nodejs (presi dalla mia molto personale Jakefile):
var Handlebars = require('handlebars');
precompile = (function() {
//Lovingly extracted from Ember's sources.
var objectCreate = Object.create || function (parent) {
function F() {}
F.prototype = parent;
return new F();
},
Compiler = function() {},
JavaScriptCompiler = function() {};
Compiler.prototype = objectCreate(Handlebars.Compiler.prototype);
Compiler.prototype.compiler = Compiler;
JavaScriptCompiler.prototype = objectCreate(Handlebars.JavaScriptCompiler.prototype);
JavaScriptCompiler.prototype.compiler = JavaScriptCompiler;
JavaScriptCompiler.prototype.namespace = "Ember.Handlebars";
JavaScriptCompiler.prototype.initializeBuffer = function() {
return "''";
};
JavaScriptCompiler.prototype.appendToBuffer = function (string) {
return "data.buffer.push(" + string + ");";
};
Compiler.prototype.mustache = function (mustache) {
if (mustache.params.length || mustache.hash) {
return Handlebars.Compiler.prototype.mustache.call(this, mustache);
} else {
var id = new Handlebars.AST.IdNode(['_triageMustache']);
if (!mustache.escaped) {
mustache.hash = mustache.hash || new Handlebars.AST.HashNode([]);
mustache.hash.pairs.push(["unescaped", new Handlebars.AST.StringNode("true")]);
}
mustache = new Handlebars.AST.MustacheNode([id].concat([mustache.id]), mustache.hash, !mustache.escaped);
return Handlebars.Compiler.prototype.mustache.call(this, mustache);
}
};
return function precompile(string) {
var ast = Handlebars.parse(string);
var options = {
knownHelpers : {
action : true,
unbound : true,
bindAttr : true,
template : true,
view : true,
_triageMustache : true
},
data : true,
stringParams : true
};
var environment = new Compiler().compile(ast, options);
return new JavaScriptCompiler().compile(environment, options, undefined, true);
};
}());
strPrecompiledTemplate = item.handlebarsTemplateFolders.map(function (dir) {
console.info("\tProcessing " + dir);
return readdirRecursiveSync(dir).map(function (file) {
console.info("\t\t" + file);
var content = fs.readFileSync(file, 'utf-8');
content = Handlebars.precompile(content);
file = file.replace(/\.[^\.]+$/, '').replace(/^src\//g, '').substr(dir.length).replace(/^\/+/, '');
// Pay attention: The wrap in Ember.Handlebars.template() is important!
return "Ember.TEMPLATES['"+file+"'] = Ember.Handlebars.template("+content+");";
}).join("\r\n");
}).join("\r\n");
Se si utilizza 'gulp' Recentemente ho pubblicato un pacchetto di NPM chiamato [brace-templates GULP-] (https://www.npmjs.org/package/gulp-ember -templates) che compilerà i tuoi template manubri in javascript e potrai quindi concatenarli in un unico file – Stuart
