Regex to match the following (JavaScript):

before

before {each:1,shared:1}

after

after {each:1,shared:1}

The patterns should match at the beginning of a line, and ends at the end of a line. The before/after part should be captured into backreference $1 and the {} part should be captured into backreference $2 (if it exists).   

Here's what I've got so far, I think it's close, the only real problem I know of is that in the simple before/after case it's capturing the before/after into backreference $3 instead of $1. 

^ *(before|after) *?({.+?})(?= |$)|(before|after)(?= |$)
