backbone: how to pass bootstrap data without server side tags

The normal way to bootstrap your app with backbone as described in the docs is this

var Accounts = new Backbone.Collection;
Accounts.reset(<%= @accounts.to_json %>);

Here, we are using the server side tags <%= ... %>, <?php echo ... ?>, etc.

But in my app I am passing very thin HTML from the server. Something like this

<html><head></head><body></body>
<script src="init.js"></script>
<html>

In this case how should I bootstrap my data for my backbone models and collections?

Backbone recommends against using fetch

Note that fetch should not be used to populate collections on page load — all models needed at load time should already be bootstrapped in to place. fetch is intended for lazily-loading models for interfaces that are not needed immediately.

But I wonder if that's the right thing to do in cases like mine?

I didn't want to put my opinion as an answer, but I think I can say, "there is no reason, technical or otherwise, not to use fetch to load your models on page load in this use case". 8)

You need your JS code to be parsed by your server side platform and that it inserts the data on it.

Two approaches can be:

1. Make you init.js to be parsed by your server side

<html>
  <script src="init.js.php"></script>
<html>

In your initi.js.php you can use the interpolate tags.

2. Load the data in a separate interpretable JS file

<html>
  <script src="data.js.php"></script>
  <script src="init.js"></script>
<html>

The data.js.php can be some thing like this:

MyApp.data = <?php echo ... ?>

In your init.js you can use MyApp.data to reset your Collections.
