Plezi - the Ruby framework for realtime web-apps, websockets and RESTful HTTP

Plezi - a real-time web application framework for Ruby

Note: at this point, plezi.io is mostly a wrapper around the iodine Ruby server. Use iodine directly if possible.

Are microservices on your mind? Do you dream of a an SPA that's easy to scale? Did you wonder if you could write a whole Websockets, RESTful AJAX back-end with just a few lines of code (business logic not included)?

Welcome to your new home with plezi.io, the Ruby real-time framework that assumes the business logic is seperate from the web service logic.

Short and Sweet

What if your next Pub/Sub application could be as easy as:

require 'plezi'
class MyChatroom
  # HTTP
  def index
    render :index
  end
  def on_open
    subscribe channel: :chat
    @name = ::ERB::Util.h(params[:nickname] || "anonymous")
    publish channel: :chat, message: "#{@name} joined the chat."
  end
  def on_message data
    publish channel: :chat, message: "#{@name}: #{::ERB::Util.h data}"
  end
  def on_shutdown
    write "Server is going away. Come back again some other time, #{@name}."
  end
end

Plezi.route '/(:nickname)', MyChatroom

What does Plezi have to offer?

Plezi is a Rack based framework with support for native (server side implemented) Websockets.

Plezi will provide the following features over plain Rack:

• Object Oriented (M)VC design, BYO (Bring Your Own) models.

• A case sensitive RESTful router to map HTTP requests to your Controllers.

  Non-RESTful public Controller methods will be automatically published as valid HTTP routes, allowing the Controller to feel like an intuitive "virtual folder" with RESTful features.

• Raw Websocket connections.

  Websocket connections are now route specific, routing the websocket callbacks to the Controller that "owns" the route.

• Auto-Dispatch (optional) to automatically map JSON websocket "events" to Controller functions (handlers).

• Native Pub/Sub provided by Iodine.

• Automatic (optional) scaling using Redis.

• An extensible template rendering abstraction engine, supports Slim, Markdown (using RedCarpet) and ERB out of the box.

• Belated, extensible, asset baking (optional fallback for when the application's assets weren't baked before deployment).

  It's possible to define an asset route (this isn't the default) to bake assets on the fly.

  In production mode, assets will be baked directly to the public folder supplied to Iodine (the web server) with a matching path. This allows the static file server to serve future requests.

  However, during development, baking will save the files to the asset's folder, so that the Ruby layer will be the one serving the content and dynamic updates could be supported.

Things Plezi doesn't do (anymore / ever):

• No DSL. Plezi won't clutter the global namespace.

• No application logic inside.

  Conneting your application logic to Plezi is easy, however, application logic should really be independent, reusable and secure. There are plenty of gems that support independent application logic authoring.

• No native session support. If you must have session support, Rack middleware gems provide a lot of options. Pick one... However...

  Session have been proved over and over to be insecure and resource draining.

  Why use a session when you can save server resources and add security by using a persistent connection, i.e. a Websocket? If you really feel like storing unimportant stuff, why not use javascript's local storage on the client's machine? (if you need to save important stuff, you probably shouldn't be using sessions anyway).

• No code refresh / development mode. If you want to restart the application automatically whenever you update the code, there are probably plenty of gems that will take care of that.

Do notice, Websockets require Iodine (the server), since (currently) it's the only Ruby server known to support native Websockets using a Websocket Callback Object.

Installation

Add this line to your application's Gemfile:

gem 'plezi'

And then execute:

$ bundle

Or install it yourself as:

$ gem install plezi

Usage

A new application (default applications include a simple chatroom demo):

 $  plezi new app_name

A simple hello world from irb:

require 'plezi'

class HelloWorld
  def index
    "Hello World!"
  end
end

Plezi.route '*', HelloWorld

exit # <= if running from terminal, this will start the server

Documentation

Plezi is fairly well documented.

Documentation is available both in the forms of tutorials and explanations available on the plezi.io website as well as through the YARD documentation.

plezi's Issues

Long polling example

Hi,

I would like to use plezi as a long polling HTTP server, which means that I don't want to use it as a fallback from websockets but purely a long polling web server. Are there any example on how to accomplish this?

Also, would it be possible to use these capabilities inside an existing rack/grape ruby app? Migrating from rack would be ok but would need to preserve Grape.

WebSocket connection to 'ws://localhost:3000/ws' failed: Error during WebSocket handshake: Unexpected response code: 200

could you please have a look at this error, I can't figure it out

How to skip Plezi (iodine) start server when use rake with Rails?

sorry for my poor English...

plezi/lib/plezi.rb has code like

Iodine.threads = 30
Iodine.run { puts "Plezi is feeling optimistic running version #{::Plezi::VERSION}.\n\n"}

I use the super easy way to load from Rails & add plezi to Rails Gemfile , Rails will auto load Gemfile gems ...... so I can't skip Iodine server start when I use rails rake

rake db:migrate

Iodine server will up and can't skip , even I havn't load any plezi server in Rails

add some code like

if !ENV || !ENV['_'].include?('rake')
  ...#Iodine.run here
end

maybe solve this issue?

Architectural clarification

Hi! I'm not an expert in websockets field and still have a few practical experience with them, only theoretical researches, started some time ago from Faye, Rack bottleneck (partly solved as socket hijacking mechanism) and search for better alternatives that led to invention of Iodine/Plezi. So I just want to clarify some points.

1. Starting from simple example - chat application, as in your example. You say that Plezi is the wrapper around Iodine web server. How tightly is it coupled to it? If I start app with rackup config.ru -p 9292 - it works. But If I replace Iodine with puma - it does not work:

→ bundle exec puma                 
Puma starting in single mode...
* Version 5.0.2 (ruby 2.7.1-p83), codename: Spoony Bard
* Min threads: 0, max threads: 5
* Environment: development
Running Plezi version: 0.16.4
* Listening on http://0.0.0.0:9292

App is opening, but websockets do not work:

(index):190 WebSocket connection to 'ws://0.0.0.0:9292/' failed: Error during WebSocket handshake: Unexpected response code: 200
init_websocket @ (index):190
(index):203 

So is it possible to interchange Iodine web server with others - puma, falcon? What features have Iodine in comparison with Puma (nio4r) related to sockets?

2. More practical example. I have an Rails app (on Puma) with separate background (Sneakers/RabbitMQ) workers. Workers change state of models and Frontend should be notified about these changes. I want to replace long polling with Websockets. What architecture should I consider, if I choose Plezi framework?
   First, good choice is to separate Websocket server and HTTP server, which could remain Puma. Second, we need some "Interconnector" block to communicate between my app or background workers to be able to send messages to websocket channel (i.e. that model has been updated). What is this "Interconnector" in case of Plezi? Some redis-baked logic? Do you have some docs of how to construct such solution? We could find drawing of similar architecture from AnyCable docs. How it transforms with use of Plezi/Iodine?

Looking forward for your answer and thanks in advance! )

ERROR -- : could not obtain a database connection within 5.000 seconds (waited 5.000 seconds) (ActiveRecord::ConnectionTimeoutError)

I really appreciate your kind and detailed response to all my reported issue since recently I am trying to utilize Plezi to create some websocket application.

Whenever I refresh the page more than twice, the server crashes and with this error message:

I am sure that the websocket connection is closed and the controller on_close action is triggered...
I wonder what causes the server to crash and how to fix it...

Gap in documentation for serving static assets

When learning Plezi, it's important to know how to serve static assets, in order to try making a primitive usable application example.

Gaps in the documentation make it hard to understand. I'm happy to help improve the documentation, but I need some clues :)

If I can fix this, I think it will help users understand how to take examples in irb and then later understand how they work with Rack, etc.

I'm looking at: http://www.plezi.io/docs/routes

• Fine: From the heading "Defining a Route" down to (and including) "Re-Write Routes" it makes sense, and they work in irb.
• Confusing: The Plezi Assets Route.

I tried many combinations using the documentation above, but nothing seems to work as described. My main confusion is: In irb, what is a single, simple, complete example of serving a static asset? It might be a JPEG file, CSS file, or JS file that I've already got in my directory.

I can provide more examples of what I've tried, but this is what I assume would work, according to the documentation:

1. Make this directory/file structure:

   test/
       assets/images/example1.jpg
       public/images/example2.jpg
   

2. Go into the test directory
3. Run irb
4. Paste this code into the IRB, which exits at the end and starts running the Plezi/Iodine server:

   require 'plezi'
   class HelloController
     def index; "Hello, World!"; end
     def show;  "Oh, hello #{params['id']}"; end
   end
   Plezi.route "/hi", HelloController
   exit

5. Prove that the controller works by going to:
   • http://localhost:3000/ => Error 404, not found. -- OK, fine, that route isn't handled yet.
   • http://localhost:3000/hi => Hello, World! -- Good, index method was called.
   • http://localhost:3000/hi/Anton => Oh, hello Anton -- Good, show method was called with implicit id parameter.
6. But now, how do I access my example.jpg (from point 1 above)? These paths all give the 404 error:
   • http://localhost:3000/example1.jpg
   • http://localhost:3000/images/example1.jpg
   • http://localhost:3000/public/example1.jpg
   • http://localhost:3000/public/images/example1.jpg
   • http://localhost:3000/assets/images/example1.jpg
   • ...and I tried all of these with example2.jpg too, which also all gave 404 errors.
7. I also tried modifying the code like this, but it made no difference:

   require 'plezi'
   require 'pathname'; Root = Pathname.new(File.dirname(__FILE__)).expand_path
   Plezi.assets = Root.join('assets').to_s
   class HelloController
     def index; "Hello, World!"; end
     def show;  "Oh, hello #{params['id']}"; end
   end
   Plezi.route "/hi", HelloController
   
   # I also tried adding this, but it didn't help either:
   #Plezi.route '/assets', :assets
   
   exit

I understand that it is perhaps not sensible to run examples in irb that we expect to throw away, while also relying on actual permanent files (for assets). However, as someone learning this it is easier to understand a single app.rb file alongside other asset files, before we make the leap to Rack.

Finding a websocket session and send message

Hi, I was able to find a specific websocket session and send message to the client with following code

Iodine::Websocket.each do |ws|
  if ws.params[:cpid] == cpid
    ws.write "hello"
  end
end

But now something not working as expected. The client keep sending message to server in every 15 seconds but I was not able to find it from the code above. The only change I made to the server related to plezi is changing iodine config from -w 1 to -w 3.
Please help out if there any workaround or better way to find and send message to a specific websocket.

I tried to rollback to the workable version, but it crashed as well...
How can I make this work? Thank you!

Upgrade to bundler 2.0

We would like to upgrade our project to bundler 2.0. Can plezi gemspec be changed to not depend on a specific bundler? Right now I am getting an error because plezi depends on ~> 1.14

I am pretty sure that the string is encoded in UTF-8...I got no idea why this error occur...
Do you have any idea?

Should add param support to routes?

I'm just thinking out loud if the routes method should support parameters / optional parameters, so we could have something like this:

route '/(:locale{en|de|ru})/book/:id' do
  params[:locale] # => en or de or ru
  params[:id] # => id supplied
end

seems like a nice touch, but should be in the core library or in a different gem (if at all)?

any alternative of method "collect" in chatroom tutorial?

I was making a chatroom app with plezi and just found that the collect method had been deprecated...
Just wondering if there is any alternatives of this method? thanks!

Documentation help needed.

I'm rewriting Plezi, but rewriting the documentation is far from being my forte... for one, I'm not a native English speaker.

If you want to write a tutorial or add documentation for the Ruby code, please jump in.

You'll need to fork this project for adding YARD documentation using code comments or fork the documentation web application if you're writing any tutorials or help articles.

Help articles and tutorials are written using markdown (the documentation application will convert it all to html, no worries).

Most of the documentation currently references the older (v.0.12.x) API and is dire need of a total rewrite... even simply deleting irrelevant parts will be a help.

Thanks!

unable to re-encode requests to safe utf-8 encoding

trying out the rack-utf8_sanitizer gem, we'll see how it works.

server shutdown when one or more client has a poor connection

switching between mobile and wifi network access works fine , however when i went to a specific area ( where the internet is not good ) , i found that server consider that as a slowloris attack and i understand that , but why the server go down if he receive too many "slowloris"

Server configs

Hi,

cf http://www.rubydoc.info/gems/plezi/0.15.1/Plezi
I am trying to figure out how to set listening port, since the code seems to not not expose methods for this.

is it possible?

ERROR -- : undefined method `close' for #<Iodine::Http::Response:0x007fad464d6160> (NoMethodError)

This error message keeps showing when I use websocket api to send message....

here is the whole stack:

    response.close
    return false
  end
  broadcast :_send_message, {event: :chat, from: params[:id], message: data["message"], at: Time.now}.to_json
end

How can I solve this problem? Thanks!

Failing at higher concurrency

Hi @boazsegev,

I'm following the-benchmarker/web-frameworks#2288

I'm running on a 4xCPU / 8 G RAM (Linux). The Dockerfile create for plezi is

FROM ruby:2.7-alpine
WORKDIR /usr/src/app
COPY . ./
RUN apk add build-base
RUN bundle config set without 'development test'
RUN bundle install
CMD bundle exec iodine -w $(nproc) -p 3000 -t 1

The command I'm running is
wrk --latency --duration 5s --connections 64 --timeout 8 --threads 8 http://172.17.0.2:3000/

The idea is that is increase concurrency level

• 64
• 256
• 512
• 1024
• 2048

When I run manually, everything is OK, but when I run it in an automated ways, it fails (stops) and a concurrency of 256.

Regards,

create function is not synchronized

hello again ...
while trying to send a considerable amount of request via HTTP ( as ws ) to the create function , i figure out that some of data is lost when trying to call the create function many time at the same time ...
i tried to use mutex to handle the problem , but nothing changed
when i start iodine with one worker and one thread nothing is lost .
EDIT
i apologise , about the Mutex resolve the problem by using this :

semaphore = Mutex.new
 semaphore.synchronize {
    # the whole create statement here ....
  }

however i still thinking that iodine need to handle that without using Mutex on my code ...

"rails generate controller" triggers iodine server to start

Every time I use rails g controller command, it will inevitably trigger iodine server to start...Any way to avoid this from happening? Thanks again for the help!

From the curl point-of-view https://ec.haxx.se/http-response.html
there should not be Transfer-Encoding: chunked AND Content-Length: 7700 AND there should be chunk size.

Chunked transfer encoding

An HTTP 1.1 server can decide to respond with a "chunked" encoded response,
a feature that wasn't present in HTTP 1.0.

When sending a chunked response, there's no Content-Length: for the response to indicate its size.
Instead, there's a Transfer-Encoding: chunked header that tells curl there's chunked data coming and then in the response body, the data comes in a series of "chunks".
Every individual chunk starts with the size of that particular chunk (in hexadecimal),
then a newline and then the contents of the chunk.
This is repeated over and over until the end of the response, which is signalled with a zero sized chunk.
The point of this sort of response is for the client to be able to figure out when the responses has ended even though the server didn't know the full size before it started to send it.
This is usually the case when the response is dynamic and generated at the point when the request comes.

Clients like curl will, of course, decode the chunks and not show the chunk sizes to users.

JSON event length is limited

When using the included websocket client and auto-dispatch, it appears that the length of a event sent from the browser to plezi is limited.

When the JSON-stringified event is up to 156 bytes, everything works.

Over that length, plezi receives corrupted data when on_message is called and cannot parse it. It then prints "AutoDispatch Warnnig: Received non-JSON message. Closing Connection." on its console. Investigation led to me discover that the JSON.parse(data) call in plezi's controller, in the on_message() method. e.g.

JSON::ParserError: 784: unexpected token at '??{"??en?:"??",??n"??23??th??i??a??st??xt??"u??":??om??ah??:2??59??22?e9??a0??4b??c7??c9??20??0b??8:??ah??la?ge?? g??k ??k ??as??kd??ls??ks?? s??ks??jf??df??sd??kj??df??dl??lf??dl?? X?'

This should have been a JSON string, but it got mangled somewhere in between. It could be iodine or facil.io ?

Help needed!

Hello!
I do not understand how to use sample chat room code you have as an example ((( I started server:

→ ruby chat.rb

Iodine.listen2http is deprecated, use Iodine.listen(service: :http).
WARNING: :app is deprecated in Iodine.listen and Iodine.connect. Use :handler

but when I'm trying to connect to it via js websockets:

ws = new WebSocket("ws://localhost:3000")

I get an error from server:

Can't deploy to heroku

I'm pushing a rails app that relies on plezi for websockets to heroku. I was using puma, but removed it

I followed heroku documentation but it seems to be biased toward big applications, but mine only has 4mb. Has anyone had this problem before?

message_size_limit uninitialized constant Iodine::Http

when i try to put Iodine::Http::Websockets.message_size_limit = 42000 , i got the excpetion : uninitialized constant Iodine::Http
changing the value on the main file to bundle exec iodine -v -maxms 4194304 -t 16 -w 20 -www ./public not changing anything ...
my need is to make socket send message for more than 4 Mb .

Thank you for your time!

rabbitmq

Hi Bo,

in the https://github.com/boazsegev/iodine/blob/master/SPEC-PubSub-Draft.md document
you mention :rabbitmq as a possible value for the :match opt.

Do you have some sample of plezi code using iodine/rabbitmq support for the pubsub system instead of redis?

thanks in advance :)

SyntaxError in generated config.ru

plezi new whatever

will generate config.ru with

Iodine::DEFAULT_HTTP_ARGS[:public] = ||= './public'

which leads to

Startup error: undefined method `to_h' for #<Array

I'm following the readme instructions, however Plezi won't startup on my system (SnowLeopard, ruby 1.9.3v551). Here's my gem list & stack trace. Happy to provide more... Thanks.
