Streaming Assets (JS / CSS / Images) from Amazon S3 with Express.js

I recently posted my Node.js blog on AppFog. I am planning on using a bucket on Amazon S3 to stream my assets (javascript / stylesheets / images).

How can I make sure Express.js gets static assets in my Amazon S3 bucket instead of the regular one /public

?

I would not pass resources through a node server - it is a waste of resources and you have to deal with HTTP cache headers.

Instead, your HTML should link directly to the S3 bucket. Instead:

<script src="/js/script.js"></script>

do:

<script src="//s3.amazonaws.com/bucket/js/script.js"></script>


Considering that you are migrating, just set up a permanent redirect.

app.get(/^\/(js|css|images)\/.*/, function(req, res) {
    res.redirect(301, '//s3.amazonaws.com/bucket' + req.path);
});

This will redirect all requests for things in the js, css and images folders to the S3 bucket. For example, / js / script.js will be redirected to // s 3.amazonaws.com/bucket/js/script.js.

This will help ease the transition, but you should move your site links to S3 URLs to eliminate unnecessary HTTP call reason by redirecting it.

If you really need to do this, use pipe () from the requests library: https://github.com/mikeal/request#streaming
