Mustard - client side food ordering

Mustard is a library that makes it easy to add powered food ordering to any website. This currently involves displaying a list of restaurants, an interactive menu, and a confirmation page.


Mustard currently must be served by a server that proxies the API or can make requests to the API and insert the result into the page. Currently, we provide the node module deliveratorjs, which provides this and other functionality.

Quick start

The minimal page that will serve an menu is the following (assuming that mustard.js is in /ordrin/script and main.css is in /ordrin/style):

<!Doctype html>
    <link href="/ordrin/style/main.css" rel="stylesheet" type="text/css">
    <!--[if lt IE 9]><script src=""></script><![endif]-->
      var ordrin = typeof ordrin==="undefined"?{}:ordrin;
      var ordrin.init = typeof ordrin.init==="undefined"?{}:ordrin.init;
      ordrin.init.rid = 141; // the restaurant's ID = "menu";
      ordrin.init.render = true;
      ordrin.restaurantUrl = ordrin.orderUrl = location.origin+"path/to/api/proxy";
        var ow = document.createElement('script'); ow.type = 'text/javascript'; ow.async = true;
        ow.src = '/ordrin/script/mustard.js';
        var s = document.getElementsByTagName('script')[0];
        s.parentNode.insertBefore(ow, s);  
    <div id="ordrinMenu"></div>

A few things to note about the page:

  1. We only support loading Mustard asynchronously.
  2. Currently, all parameters must be passed to Mustard by assigning to keys in the ordrin javascript object.
  3. For Mustard to function, the menu HTML must be in a <div> with the id ordrinMenu. If Mustard is rendering the menu, as in this example, the <div> should be empty as its contents will be overwritten.

No Proxy

If you want to make this quick start page but don't have a server that proxies the API, you can still render the page by adding only a couple of lines of code to the script tag in the quick start page. After the line that sets the ordrin variable, the following two lines should be added:

ordrin.init.noProxy = true; = {{{data}}};

Fill in {{{data}}} by making a request to the restaurant details function of the Restaurant API and replacing {{{data}}} with the value of the menu key in the repsonse to that API call.

In this case, the restaurantUrl and orderUrl variables are not needed and will not have any effect, so the line setting them is not required.


Mustard includes the JavaScript API wrapper, tomato (our persistence library), Mustache (in ordrin.Mustache) and EventEmitter2.

Once Mustard initializes its instance of EventEmitter2, it will call ordrin.emitterLoaded with that instance and then delete ordrin.emitterLoaded.


This is a summary of the interface to Mustard. More detail can be found in the next section


Mustard may use the following values if they are set in ordrin.init before Mustard loads:

Mustard interface

After Mustard has loaded, it will emit an event moduleLoaded.mustard with a reference to ordrin.mustard, which will have the following functions:

The Pages

Mustard can render three pages: a list of restaurants, a menu, and a confirmation page.

All these pages currently use the following values. Many can be initialized in ordrin.init, and some can be accessed through ordrin.mustard

Delivery address

The address that food should be delivered to. This should be an instance of ordrin.api.Address

Direct: ordrin.init.address

Accessors: ordrin.mustard.getAddress(), ordrin.mustard.setAddress()

Delivery date/time

The time at which the food should be delivered. This should be either the string ASAP, a string of the form MM-dd+HH:mm, or a Date object in the future.

Init: ordrin.init.deliveryTime

Accessors: ordrin.mustard.getDeliveryTime(), ordrin.mustard.setDeliveryTime()


Tells Mustard what to do with when the page loads. The value should be "menu" to process the menu, "restaurants" to process the restaurant list, or "confirm" to process the confirm page.



Tells Mustard whether it should create the HTML and put it in the page, or use what is already there.

Init: ordrin.init.render

No Proxy

Mustard will not make any API requests if this value is truthy.

Init: ordrin.init.noProxy

Restaurant List

Mustard will render a restaurant list into a <div> with the id ordrinRestaurants when it loads if page is set to restaurants. After Mustard has loaded, a new restaurant list can be rendered into the same <div> by calling ordrin.mustard.setAddress() or ordrin.mustard.setDeliveryTime()


A menu in the same structure as the value of the menu key in the return value of the Restaurant API details function. If this is not provided before Mustard loads, Mustard will attempt to download it from the API using the restaurant ID.


Accessors: ordrin.mustard.getMenu()


A tray of items. An instance of Tray.

Init: ordrin.init.tray

Accessor: ordrin.mustard.getTray(), ordrin.mustard.setTray(), ordrin.mustard.initTrayFromString()


The tip as an integer number of cents.

Direct: ordrin.init.tip

Accessor: ordrin.mustard.getTip()

This page also uses the following values:

Restaurant List

The list of restuarant objects in the same form as the return value of the delivery list request in the Restaurant API. If this is not provided before Mustard loads, Mustard will attempt to download it from the API using the address and dateTime.

Restaurant List Template

A string containing a Mustache template for rendering the list of restaurants. The default is at templates/restaurants.html.mustache

Init: ordrin.init.restaurantsTemplate

Menu URI root

Init: ordrin.init.menu_uri


Mustard will render a menu into a <div> with the id ordrinMenu when if loads if page is set to "menu". After Mustard has loaded, a new menu can be loaded into he same <div> by calling ordrin.mustard.setRestaurant()

This page also uses the following values:

Restaurant ID's ID number for the restaurant

Init: ordrin.init.rid

Accessors: ordrin.mustard.getRid()

Menu Template

A string containing a Mustache template for rendering the menu. The default is at templates/menu.html.mustache.

Init: ordrin.init.menuTemplate

Dialog Template

A string containing a Mustache template for rendering the dialog box for selecting item options and quantity. The default is at templates/dialog.html.mustache.

Init: ordrin.init.dialogTemplate

Tray Item Template

A string containing a Mustache template for rendering an item in the tray. The default is at templates/trayItem.html.mustache.

Init: ordrin.init.trayItemTemplate


Mustard will render a confirmation page into a <div> with teh id ordrinConfirm when it loads if "confirm".

This page also uses the following values:

Confirm Template

A string containing a Mustache template for rendering the confirmation page. The default is at templates/confirm.html.mustache.

Init: ordrin.init.confirmTemplate
