Experimental web app using WebRTC and remoteStorage.js

gHost - unHosted Photo Album

gHost is an experimental web application based on HTML5, CSS3 and JavaScript.

gHost uses jQuery and two new great technologies called WebRTC and remoteStorage.js; used, respectively, to capture the webcam stream without plugins and to host the pictures taken, leaving users in control of their data.

Demo: https://ghost.5apps.com/

ghost's Issues

similar project: heliogram

Heliogram is a very similar app in development by @skddc (of 5apps.com). You can try it out at https://github.com/skddc/heliogram – doesn’t seem like it uses WebRTC but a different means of native webcam streaming.

not working in Firefox?

Hi! I'm not getting the 'Allow access to your webcam' prompt when using https://ghost.5apps.com/ from Firefox on Windows.

In IE it correctly reports that WebRTC (specifically, getUserMedia) is not supported in that browser. In Chrome and Opera it works correctly.

But on Firefox it just stays at the splash screen without any error message.

images get overwritten

Sometimes there’s an alert »Could not find "pictures/ghost/8" on the remoteStorage« (or any number). Then that photo is either not displayed (just as broken image) or the images just stop showing up at that image.

Then when you take new photos, they overwrite these images. When you then reload, the other images show up again, except the ones which were overwritten.

Even when an image »can not be found«, that pointer should never be overwritten. In place of the image should be shown an empty space with a message »image not found, try reloading« or something like that.

doesn’t work anymore

When I put in my user address, the app just reloads and I get a bunch of errors in the console. Among others »There wasn't anything for "pictures/ghost/count"«. I left in the other errors also because they might cause other issues. (I use AdBlock, HTTPS everywhere and Disconnect.me)

updating Ghost to remoteStorage release v0.7

Hi @vcuculo,

Good news: @nilclass tagged the release of remoteStorage.js version 0.7.0 yesterday. here is an example of how it works:
https://github.com/michielbdejong/remoteStorage.js/blob/master/example/minimal/index.html
so because sync is "behind" the modules with remoteStorage.js 0.7, the app architecture is a matter of:

• putting domain code into the module (notes.js in the example)
• send controller actions to the module
• update the DOM only when the module gives you a change event

here are reference docs:
http://remotestoragejs.com/doc/code/files/remoteStorage-js.html

let me know what you think! it would be nice to update this so we can have Ghost-unhosted-webrtc compatible with the latest lib before we add it on https://unhosted.org/apps/ :)

using »ghost« module instead of generic »pictures«

Currently gHost wants to access my »ghost« stuff. That defeats the purpose of modules a bit. Better would be to use »pictures«, so it can be reused by other picture apps.

update to remotestorage.js v0.8.0-rc2

hi!

there is a release candidate for IndexedDB-based rewrite of remotestorage.js. it should be a lot better than version 0.7, especially when working with (big, binary) photos!

can you maybe help us to test it by adding it to gHost? instructions are on http://community.remotestorage.io/t/migrating-from-0-7-to-0-8/63

many thanks!
Michiel

It is "remoteStorage.js"

We (the remoteStorage team) recently agreed on how to spell/capitalize/... the term "remoteStorage". Please change "RemoteStorageJS" to "remoteStorage.js" :)

share images

I used ghost last weekend at our unconference in Unhost to snap some pictures while doing a presentation on working unhosted apps. IT WAS AMAZING!

Now I want to share some of those pictures. It would be great if a photo would have something like a sharing switch (something revealed on hovering the photo). Then the public photos should be displayed in the same wall-like style on http://vcuculo.github.com/ghost-unhosted-webrtc/#user@host

Btw, you should a) shorten the repo name to just »ghost« to make the link shorter b) deploy using 5apps.com and optionally get a nice domain for the app! :)

Update remoteStorage.js to 0.10.0-beta

Hi Vittorio,

We just released remoteStorage.js 0.10.0-beta with completely rewritten caching and sync backends (and fixing anon mode, which was broken in 0.9). Some apps are already using it in production with no problems so far (but better performance and stability). Would be great, if you could update it in Ghost as well.

We broke the API in very few places (only removing some deprecated things), but it should be a 1-minute upgrade, in case you're using one of the old calls. The library comes with automatic migration for existing cached data, which should be transformed to the new better format without having to do anything in your app.

Check out the changelog for details.

Cheers,
Basti
