Asynchronous and recursive data URL generator/embedder for single files or web pages.

Installation

$ go install github.com/buffermet/epoxy

Usage

First grab the source of a web page and save it locally.

$ curl https://twitter.com/ > twitter-index.html

Now you can use epoxy to fetch every resource in the web page and embed them into the source file.

$ epoxy -source twitter-index.html -origin https://twitter.com/ -recurse 3 -no-html

You can set the recursion limit with -recurse to choose how many nested resources should be embedded as data URLs for every resource.

If you want to turn a single file into a data URL, set the recursion to 0 and epoxy will generate a data URL for the -source file contents.

$ epoxy -source twitter-index.html -recurse 0
