🔍 Go diffing service for comparing changes to webpages

Differ

first, install go, then cd to the folder, build & run. default port is 8080.

$ cd differ
$ go build
$ ./differ

It's only got one route: /, hit it with a & b query params, where a & b are urls to diff, eg:

http://localhost:8000/diff?a=http://www.apple.com&b=http://www.apple.com/a

an extra param format sets the output format, which takes one of html, htmlraw, text or json, default is html.

diffing settings can also be controlled by passing in additional query params, setting things like matchThreshold & matchDistance, in lieu of proper documentation, please see the NewDifferFromRequest func in differ.go.

go-calc-diff's Issues

Archiving this repo

In accordance with edgi-govdata-archiving/overview#217, we’re planning to archive this repo — it hasn’t seen updates in a year and a half and isn’t being actively maintained. It was originally made to assist in web-monitoring, but that project now uses a different solution for diff-match-patch style text diffing. If you’re subscribed to this repo but missed that conversation and think this repo should stay active, please post here to let me know in the next few days!

"format" param is getting confused with input format

We should rename the "format" param, as it refers to output format, not input format, param name should make this distinction clear.

Use application/json content-type for JSON-formatted diffs

It would be really helpful for automatic parsing on the client side if the response for JSON diffs had a Content-Type: application/json header!
