with-socket.io example was using a single index file and was managing connection in there. This would lead handling connection (disconnecting and reconnecting) in each added page.
I updated example with addition of `_app.js` and handled connection in there. This helped only subscribing to event in page and maintaining connection throughout example.
* Examples: clarify language around Yarn create & npx
* add missing READMEs and create-next-app usage
* suggest people tag jthegedus in firebase related issues
* add yarn alt instructions
* cerebraljs example readme & fixes
* remove global npm install of create-next-app
* add npx to create-next-app command in examples
* add bash to shell snippets
* add yarn create to next-app command in examples
* fix READMEs named with lowercase
* change READMEs to use UPPERCASE
With a hard coded address on the client, the app no longer works when deploying, which is annoying since there's a handy 'deploy now' button on the readme.
By removing the hard coded address socket.io will connect to the location host automatically so it works both on development and production.
* Add socket.io example
* [update] stop handling events before unmount
* [update] add deploy to now button
* Fix linting problems
* Fix last missing linting problem
