renraku makes async typescript functions callable across boundaries.
servers can expose functions for clients to call. iframes can expose functions for pages to call. websockets. web workers. the details melt away, and you just focus on async functions.
you are looking at prerelease v0.6 @e280/renraku@next, which does not yet have docs. you may instead like to see the v0.5 @e280/renraku@latest readme.
