Can you explain the significance of JST in an angular template?

Recently I stumbled upon some code that uses the JST prefix before the template in Angular:

For example:

$routeProvider
  .when("/login", {
    template: JST["app/templates/login"],
    controller: "LoginController"
  })

In the past, I would do it like this:

$routeProvider
  .when("/login", {
    template: "app/templates/login",
    controller: "LoginController"
  })

What does this JST mean in an Angular template? And is there any difference between the two styles?

Just for your information - This code comes from an app built with linemanjs.

Answer №1

One potential explanation is that it may be a hash object within your code that stores keys and values as URLs for HTML template files.

var templates = {
    "app/templates/login": "something.html"
};

$routeProvider
    .when("/login", {
        template: templates["app/templates/login"],
        controller: "LoginController"
    })

Answer №2

My approach to integrating JST templates into Angular is as follows:

app.factory('$jst', ['$sce', function($sce) {
  var methods = {
    template: function(name) { return $sce.trustAsHtml( eval(JST[name])() ) }
  };
  return methods;
}]);

app.controller('AnotherCtrl', ['$scope', '$http', '$jst', function($scope, $http, $jst) {
  $scope.template = $jst.template('template-name-here');
}]);

When it comes to the HTML side of things, here's what I do:

<div ng-controller="AnotherCtrl">
  <div ng-bind-html="template"></div>
</div>

This method provides a clean and efficient way to utilize JST templates within AngularJS.

By the way, this technique seamlessly integrates with SailsJS as well.

Answer №3

If your app uses JST templates, check out this helpful guide. JST acts like a dictionary that stores templates as JavaScript functions. Typically, this JST collection (dictionary of functions) is generated during the build process and saved as a JS file that's woven into the app somehow. The compiled JST object is fed a series of template .html files.
