Please Add a README about usa-election-map HOT 5 CLOSED

👍 (I've been meaning to get around to this)

from usa-election-map.

@jacksonjude: sorry, I feel like this issue was rude . . . I didn't offer any detail about my request. Apologies for that.

You've made an awesome product. I'm a fan of the YouTube channel Let's Talk Elections, and he plugged your map in a recent video.

I'm curious if open source contributions would be welcome for any of the TODO list items etc. I also wonder about the instructions for getting a fork running locally.

No worries! A README is definitely something that I should've added earlier. TODO list items are definitely open for anyone to recommend, just open an issue and I'll mark it as "feature".

Running a fork locally is really simple since this code only uses the base HTML/CSS/JS stack (+JQuery, which I have included locally anyways). Just clone the repo and open index.html to run!

There is a caveat here since Chrome (and Safari) are very stingy about loading local svg files due to CORS restrictions. Fixing this CORS issue on Safari is somewhat simple (goto Develop > Disable Cross-Origin Restrictions). Chrome is a little more complicated (you can try running "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-web-security --user-data-dir=~/chromeTemp on Windows or open -a <chrome executable path> --args --disable-web-security --user-data-dir on Mac). Alternatively, you can try running it on Firefox.

I will update the README with this information since I'm realizing that this is a more complex issue than I first thought :)

I cloned and did notice the CORS issue in Chrome. On my Mac, one solution was as simple as running a local server in the repo:

brew install http-server
http-server

from usa-election-map.

That does make sense since the CORS error happens because of the "file://" protocol, and the local server changes the protocol to "localhost". I'll add that solution to the README.
