The most recent JS trend is to complain about how trendy JS is and how hard it is to keep up.
Given the amount of frameworks, libraries and `the correct way` of writing proper code and using the `correct` tools, I think meteor has his own place in the world, but I guess, there is much noise, and I guess they are not hot anymore.
Few years ago, meteor was the next big idea of the web, then:
angular
node
react
react native
ember
then no libraries anymore, as we can do it manually.
Even JQuery seems to recover and become a nice cool alternative :)
I think meteor was too short of a blip to ever land in my land..
Since then, we've navigated away from Meteor to our own custom stack that better suits our needs.
Bottom line, it's freakin awesome for prototyping real-time web/mobile apps in a VERY short period of time. There are a few companies rolling it in production, though, it just depends on what you require.
Basically, with skimping on details, they're really increasing in the future of the framework right now. You can check on their blog for more info and skim their accomplishments, upcoming releases, and current goals in the pipeline.
Who knows if they will be successful, but there is opportunity to improve web development without being a javascript front-end library.
