# - cron with cleanup of timedout clients, automatic dump
# - the dump should use array startsearch to write it line by line
# and may just use gets to read element by element and load the whole state.
# - 'help','stopserver','saveandstopserver','save','load','reset','keys' commands.
# - ttl with milliseconds resolution 'ttl a 1000'. Check ttl in dump!

gaearon / LinkThatWorksWithRedux.js
Last active November 21, 2018 03:31
Drop-in replacement for React Router <Link> that works with React Redux optimizations (https://github.com/reactjs/react-router/issues/470)
// While I claim this is a drop-in replacement, it is a little bit slower.
// If you have hundreds of links, you might spend a few more milliseconds rendering the page on transitions.
// KNOWN ISSUES WITH THIS APPROACH:
// * This doesn't work great if you animate route changes with <TransitionGroup>
// because the links are going to get updated immediately during the animation.
// * This might still not update the <Link> correctly for async routes,
// as explained in https://github.com/reactjs/react-router/issues/470#issuecomment-217010985.
