That’s awesome that spacebars clicked with you. Why does that mean that Meteor should only support one templating system? Did you see that Meteor is adding Angular support, along with React?
At the end of the day, Meteor boils down to the command line tools, isomorphic packages and DDP. The rest of the technology stack will always have a hint of flavour-of-the-month about it, whether that’s Spacebars, Famo.us, React, Angular etc.
No. Meteor is a platform, you can choose which packages and templating engines to use.
No official word from MDG, some people have different opinions about it. Let's talk about deprecating spacebars
I think you’re asking the wrong question. You should be asking - How many more people will React bring to the Meteor ecosystem?
With proper support for React - Meteor can now reach a broader audience. An audience that will be contributing new packages, updates to core packages, and supporting MDG by buying Galaxy/ Developer Subscriptions.
So, if the MDG & the Meteor Community continue to thrive - we can continue benefiting from the excellent open source software they’ve released.
Oh - and as for famo.us - they just re-wrote their engine to fix a bunch of performance issues (which stopped their initial adoption). Check it out.
