How to know if files are being successfully compressed?

[sandysaders]

Hello,

I'm wondering to see how I can know if files are being compressed? So far I have the following:

var express = require('express')
var compression = require('compression')
var zlib = require('zlib');

var app = express()
app.use(compression({level: 9}))
...

When I make a request at localhost how do I confirm in the browser that the files that we're sent over are in fact gzipped and uncompressed via the browser?

I get the following:

It doesn't look like it's compressed. Usually a compressed response will contain Content-Encoding: gzip in the response headers.

[hadijaveed]

yes but with same code posted by @sandysaders it gives the same Accept-Encoding: gzip, deflate, sbch. Can you suggest how can I make it work ?

[blakeembrey]

Can you share some code so I can reproduce it? The original issue was a general question as far as I know.

I am sorry there was a typo in my code. So it is working now !

Awesome, great to hear. I'll close this as the question was answered, but if there's any other issues feel free to continue the discussion.

It might help others if you post the solution. I found this issue having a similar problem, but couldn't see what was wrong, as you didn't post the solution 👎

@hilleer It might help if you have an issue to post the issue you're having too. This issue was a question, and the question was answered https://github.com/expressjs/compression/issues/88#issuecomment-235494836.

Fair enough :-) It was more like a solution - to post the solution he found.
