Add firebase example

[mistakenelf]

Anyone have any luck running firebase. I kept receiving errors that the firebase app had already been initialized. Does this have something to do with SSR? Whenever a hard refresh was done it would throw this error. I loaded my firebase config in the pages/index.js file and then called firebase.initializeApp(config).

@knipferrc This example uses firebase, it may help you https://github.com/now-examples/next-news

@impronunciable maybe we should add an example for firebase, since it's pretty well know 😄

Yes I still think it would be quite helpful to centralize examples, now they're a bit spread around:

• https://github.com/zeit/next.js/tree/master/examples
• https://github.com/now-examples/next-news
• https://github.com/zeit/nextgram
• ?

Or at least link them all from a single place.

Might be good to add a open source example apps section. I know you did a lot of work on relate.now.sh @sedubois, nextgram is the official example app, and next-news is a side project from @rauchg, which serves as a really good example of a production app 👍. I made next-episode which is also a small sample app.

Oh yes and there's also the examples listed in this issue: #727

@rauchg @nkzawa @arunoda what's your opinion on adding a open source projects sections?

[arunoda]

@timneutkens I think it's better if we keep them in a wiki or in a awesome-nextjs list.
BTW: There's already an awesome next.js list here: https://github.com/unicodeveloper/awesome-nextjs

May be we could link to that list from our README. (Better to do it the top of the README)

[timneutkens]

@arunoda Ah, great idea. I didn't know someone made an awesome list already 💯 Will add it.

I think in order to make nextjs become more attractive to those that are new to web development, it is a good idea to include some examples and short tutorials for how to connect and use a database. How can you create realtime apps with nextjs?
