emulate node's vm module for the browser
Just write some client-side javascript:
var vm = require('vm');
$(function () {
var res = vm.runInNewContext('a + 5', { a : 100 });
$('#res').text(res);
});
compile it with browserify:
browserify entry.js -o bundle.js
then whip up some html:
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script src="/bundle.js"></script>
</head>
<body>
result = <span id="res"></span>
</body>
</html>
and when you load the page you should see:
result = 105
Evaluate some code
in a new iframe with a context
.
Contexts are like wrapping your code in a with()
except slightly less terrible
because the code is sandboxed into a new iframe.
This module is depended upon by browserify, so you should just be able to
require('vm')
and it will just work. However if you want to use this module
directly you can install it with npm:
npm install vm-browserify

First-pass at JavaScript client SDK. JavaScript requires Node with Gulp to "browserfy" the library. It's the easiest way I found to use the swagger-js project; bundle up a wrapping method. There is no JavaScript reference guide. The swagger-js doesn't really document what they do very well, actually. Overall I'm not particularly impressed by swagger-js, it was hard to even figure out what the right method syntax was. We may want to invest time in doing it better. This required setting CORS response headers, which are currently defaulted to a fairly insecure setting. |
