Typing $ tmi kud.io should go to http://kud.io.

Filesize is long tail distribution, using average is at best meaningless, and at worst, completely misleading.. since a single outlier can skew the value. At a minimum, we should be using medians.

Even better, we should be capturing quantiles - e.g. you're in the 90% quantile, your site is performing worse than 90% of other sites when it comes to image weight, vs. you're in the 10% quantile, your site is in the top 10% percent for image size.

Unfortunately I can't use tmi at all. There is an error message right at the start.

I installed the package with yarn 1.9.4 on node 10.11.0 and tried several URLs with and without the protocol. Everytimes I get the same error message:

› tmi google.com --verbose
TypeError: Cannot read property '0' of undefined
    at Output.process (/Users/mirkoschubert/.config/yarn/global/node_modules/tmi/index.js:147:44)
    at psi.then.res (/Users/mirkoschubert/.config/yarn/global/node_modules/tmi/cli.js:31:8)
    at process._tickCallback (internal/process/next_tick.js:68:7)

I look into it when I find the time. 😏

Output still expects the CLI reports coming back from PSI whilst TMI has a different structure to output. Update tests to reflect this.

I'm slightly ashamed to admit that I don't know what this means:

Median mobile site image weight
17 kB

nor this:

+4.59 MB compared to sites in the 25th percentile

The --verbose output could perhaps elaborate that part? I could submit a PR, I just don't know what this output means and would appreciate pointers. 😅 I read #8, but it didn't help me fully understand.

For some urls there is no output at all, not even an error message, nothing, nada !

The first domain I plugged into tmi I had a typo in the url. I thought it was broken until I tried another url.

I think it could be great to add some sort of message when an http request doesn't return a response and/or times out. A message like "Could not reach http://tpyo.com at this time." might be sufficient in providing feedback to clue a user of the lack of response/typo.

Does it work with Gulp? How?

$ tmi http://redrobin.com

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: ENOENT, open '/usr/local/lib/node_modules/tmi/data/bigquery.csv'

With the latest version. Reported by @igrigorik and just verified as busted. Looking into it now.

This script doesn't seem to gather all the images from the target URL. For example, when trying it on theverge.com it returns only 70 KB, when in fact there is over 1.1 MB of images downloaded from that request.

I noticed I get a connection timeout and I believe it is because I am working behind a corporate proxy.

tmi www.google.com --verbose
connect ETIMEDOUT

I can use npm behind the proxy because it has options to set up the proxy connection.

I have an app that requires you to login first before you can use it, and when using tmi, it only checks the landing page where login happens, but I'd like to test the rest of the Backbone app behind the wall. Is this possible?

I tried many attempts, wasted few hours and I cant run tmi properly.
Can u please post a simple example to run it via gulp or grunt?
I tried many variations, here's the latest one
tmi().process(config)
which evalutes to TypeError: Cannot read property 'pageStats' of undefined
