My understanding is that Firebase doesn't provide an in-between of handling if you are offline or online -- that is, there's an offline state to show things, then going online causes to reload everything. I'm wondering about how to handle case of going online-to-offline-to-online so can handle case of figuring what's new without having to reload everything. For example, 10 posts are loaded on the feed online, then offline during which time a new comment is added to 2 of those posts and there's a new post made, then you go online then preferably the only things updated are those 2 comments and the new post made. In contrast, I think that Firebase would reload the entire screen in that case, unless building some local storage that somehow interfaces with Firebase -- or maybe I'm mistaken about the exact point of comparison with Firebase, but net question is about what a custom backend may allow for more control of loading and the user experience of that than Firebase.

Cool! I would suggest Realm, including because of announced roadmap for Realm including integrating with MongoDB, along with backup, cross device sync, 'unified backend fo rmobiel and web', and 'replace custom access control code'.

What do you think about including pagination? Would any of that have reason to be on the client, or better all on server? What more is there to pagination than this? https://stackoverflow.com/questions/26648059/sails-js-how-i-do-pagination-in-sails-js And how is that pagination impacted by sockets with updates, such as figuring where the new posts go and what existing posts have updates to include etc?

Messaging and using a socket.io library sounds awesome! https://socket.io/blog/socket-io-on-ios/ https://github.com/socketio/socket.io-client-swift

And showing uploading videos sounds awesome as well

Agreed and that’s why asking you to cover underlying concepts in a bit more depth in separate sections as it will help more in people in their goals.

Alas the auto correct in phone. My last line meant covering underlying concepts will be a great help for people especially for those who don’t come from a regular CS background and are using your courses for learning technology to use it for some purpose.

I believe the better idea would be how to make usable across platforms like Web, Android and iOS as more and more people are using at least 2 platforms to access their stuffs or for use. This is an area where people are struggling and are looking for solutions but haven’t come across yet. I am looking to Vue from that perspective and somehow after seeing details of other technologies I am more or less convinced that solution will come from HTML, CSS and JS libraries rather than something like flutter. And yes definitely I am looking for someone like you who can explain concepts of Vue in simple terms in a short span of time.

The reason is simple that people are used to these technologies. Somehow these technologies have grown beyond companies and all companies are more or less open to these technologies and they have withstood the test of time. And more use have brought new benefits like JS slow running problem is being solved to a greater extent by Google V8 and something like node. Lannguage’s own shortcomings have been addressed a lot in ES6 and it’s used across the globe and across the platforms.

That’s great but please include in your future courses and may be this one too on how to make the concept usable across the major platforms. So here a section on how to use it for Android would be of great help. It may be tedious for you but highly effective and useful for people who are your students.

And that’s why grasp of basics are more important as you now need to apply it in much broader context.

I agree 1:1 (-: however there is a shortage in projects that really 'go all the way' to a fully viable working project (both platforms, web, payments). I challenge you to do one (-; I bet many others (count me in) would be happy to invest the time and money for that one.

Agree with this ^^ Just started the course...really enjoying it so far. A sign in with Twitter & Facebook using PassportJS would also be nice.

Yeah, that would be cool!
