Yep, I wish we could use the cookie. ^.^;

v0.9.2 is out
This is a slow evolution release, containing a number of bug fixes and a few new features:
- Cookies function in
Drab.Browser
iex> set_cookie(socket, "mycookie", "value", max_age: 10)
{:ok, "mycookie=value; expires=Thu, 19 Jul 2018 19:47:09 GMT"}
iex> Drab.Browser.cookies(socket, decoder: Drab.Coder.Cipher)
{:ok, %{"other" => 42, "mycookie" => "value"}}
Drab.{Live, Core, Element, Modal}functions accept%Phoenix.HTML.Safe{}
That means you don’t need to call safe_to_string/1 anymore, just pass the safe:
html = ~E"<strong><%= nick %>:</strong> <%= message %><br>"
broadcast_insert socket, "#chat", :beforeend, html
- Tested with Elixir 1.7
Drab is now blessed to work with Elixir 1.7 and OTP 21.

- In regard to making it static…I would say no.
In ANY other language, I would say yes…but EEX templates are so efficient that I would be surprised if it’s worth it. As long as you include some type of version hash on the URL, a user who wanted their to be static could point to it with a CDN domain.

Actually, it is impossible now. Drab’s JSes are generated each time and they are different for literally each request. This is what I want to change.

After a long discussion with myself, my answers to the questions are:
1. Yes
They will be cacheable, shrinkable and easier to maintain.
"dependencies": {
"drab": "file:deps/drab",
"drab_query": "file:deps/drab" // TBD
2. Yes
Very short max_age. Drab client will grab it, and delete it from document.cookies immediately.
3. Yes
Standard Drab installation will just add plug to generate a token cookie, and Drab will start on load. We just need to solve the case, when you want to add something, like authentication token, to the connect callback. Proposition:
plug(Drab.Client, connect: false)
and
if (window.Drab) Drab.connect({auth_token: window.my_token});
Drab will not try to start if the commander is not present.
4. No
%Phoenix.Socket{} is enough. I will just do some housekeeping, moving all drab’s underscore assign to the one struct, and keep all under __drab assign.
5. No
We can’t. Session cookie is http only.
6. Yes
But I still have no idea how

Hello Grych - just trying drab-example and also starting from scratch with a new phoenix app using your instructions.
using OSX
I started off with elixir 1.6 and erlang 20.0 and could not get this working.
I then upgraded to 1.7 and 21.0 after scanning latest comments.
still no luck.
drab-example gave me this error in the browser
mix phx.server
warning: found quoted keyword “test” but the quotes are not required. Note that keywords are always atoms, even when quoted, and quotes should only be used to introduce keywords with foreign characters in them

That must be a root of an issue. Please ensure your erlang installation contains the latest openSSL. For OSX, I am using OTP installed forom both brew and port, and both are OK.

I used ASDF to upgrade elixir and erlang,
I will try… brew upgrade erlang
…==> Upgrading 1 outdated package, with result:
erlang 20.1.5 → 21.0.5

I think I have found the problem - my 2009 macbook pro is so old that my version of OSX (10.10) is no longer supported.
I have been putting off upgrading because the macbook pros have been so awful over the last 3 years.
Looks like I will have to finally upgrade to the 2018 macbook pro.
during the erlang upgrade I got…
Error: You are using macOS 10.10.
We (and Apple) do not provide support for this old version.
You will encounter build failures and other breakages.
Please create pull-requests instead of asking for help on Homebrew’s
GitHub, Discourse, Twitter or IRC. As you are running this old version,
you are responsible for resolving any issues you experience.
will be back when I have upgraded
