P2P twitter-clone built on Holochain A group of cats is called a Clutter, Cludder, Clowder, Kendle, or Kindle. Maybe it's time for a peer-to-peer shoutcast system to eat a certain blue bird.
Clutter is a work in progress. It's a sample application designed to demonstrate how easy it is to build applications on Holochain.
If you would like to simply download a build version of the latest Clutter, download and unzip the latest release
Code Status: Pre-alpha. Not for production use. This application has not been audited for any security validation.
If you want to just see Clutter in action and haven't yet installed Holochain, the best way to try it out is simply to use the version included in the latest Holochain release. Go to the Holochain Releases page and download and unzip the archive for your machine. That archive contains a full version of clutter, along with instructions for running it.
You can download the latest Clutter release directly from the Clutter Release page.
Prerequiste: Install holochain on your machine and make sure you do the step to set the $GOPATH.
Run the command:
hcdev init -cloneExample=clutter
This will create a copy of the Clutter source code in a clutter directory.
You can then run clutter in development mode with:
cd clutter
hcdev weband point your browser at http://localhost:4141 to access the UI.
--or--,
assuming that you've already setup your Holochain environment with hcadmin init you can join and run Clutter with:
cd clutter
hcadmin join . clutter
hcd clutterand point your browser at http://localhost:3141 to access the UI.
Prerequiste: Install Holochain on your machine and make sure you do the step to set the $GOPATH.
Dependencies: If you want to work on the Clutter UI, you will need nodejs (https://nodejs.org/en/) (LTS) installed, with npm or yarn (https://yarnpkg.com/lang/en/docs/install) to be able to build and copy it from the ui-src to the ui directory:
The following commands will clone the latest build of clutter to your machine (you may want to use your own fork instead of our repo) and then you will either install npm or yarn to build the UI for the app.
git clone https://github.com/Holochain/clutter.git
cd clutter/ui-src
npm install # (or yarn install)
npm run build # (or yarn build)
cd ..
After npm run build, npm start to configure and start the React UI.
Now if you want to run the app, you can run:
hcdev web
Holochain does local discovery with MDNS which is not always availble on Windows machines. So during development instead you may want to run your own local bootstrap server for node discovery. These instructions detail how to run 2 instances of Clutter and your own Bootstrap server.
Make two copies of your your clutter folder one called clutter1 and the other clutter2. Both folders will need to have a dna folder and a ui folder in each.
Firstly run the bootstrap server which will let each instance of Clutter know about its peers. The bs command is part of the Holochain install. If it doesn't work you probably need to set the $GO_PATH variable. (Soon we won't need this step)
bs
You will get a response like
2018/01/11 11:24:03 app version: 0.0.2; Holochain bootstrap server
2018/01/11 11:24:03 starting up on port 3142
Now start up Clutter in each folder.
cd clutter1
hcdev -DHTport=6001 -agentID=lucy -bootstrapServer=localhost:3142 web 3141
cd ..
cd clutter2
hcdev -DHTport=6002 -agentID=phil -bootstrapServer=localhost:3142 web 4141
You will see a response like:
Copying chain to: /Users/philipbeadle/.holochaindev
Serving holochain with DNA hash:QmVbbeDAHVxC9cTvx6UhNEeTCK99SRKfxKDz3s4mR6TnsS on port:3141
Now open a browser at http://localhost:3142/QmVbbeDAHVxC9cTvx6UhNEeTCK99SRKfxKDz3s4mR6TnsS (substituting in the DNA hash from the response above if different) and look at the Bootstrap server. You will see 2 records like this
[{"Req":{"Version":1,"NodeID":"QmTAjDmQHobs2oQZp4UrbSzkShUGVKcsQUdakHeQ4YYxRX","NodeAddr":"/ip4/0.0.0.0/tcp/6003"},"Remote":"[::1]:63187","LastSeen":"2018-01-11T12:32:15.659887156+11:00"},{"Req":{"Version":1,"NodeID":"QmWQVaqEayZJWnvxLtsKr1iyeTDp3s7m7TTE36HhAUTiTK","NodeAddr":"/ip4/0.0.0.0/tcp/6002"},"Remote":"[::1]:63153","LastSeen":"2018-01-11T12:28:40.85765899+11:00"}]
Now open a browser to http://localhost:3141 and you will see Clutter. Open another tab to http://localhost:4141 and you now have 2 instances of Clutter that you can chat between. Add a handle in each and then meow and follow each instance and you will see the meows!!
You can do all this much easier with Docker. Download the latest release from Clutter Release, unzip it and cd into the folder. Then run
cd ui-src
npm install # (or yarn install)
npm run build # (or yarn build)
cd ..
TARGETDIR=$(pwd) docker-compose up
This will build the source into a React app and install it in Holochain. Then you can open browsers to
http://localhost:3142 - Bootstrap
http://localhost:3141 - Clutter
http://localhost:4141 - Clutter
http://localhost:5141 - Clutter
and try out Clutter.
To run all the stand alone DNA tests:
hcdev test hcdev scenario collisionOfHandles
hcdev scenario followAndShareThis test spins up two nodes jane and joe and tests that following and reading posts works. To watch the network traffic and details try:
hcdev -debug scenario followAndShareThis test is designed to be run on separate machines and spins up many clones on each and confirms that they all talk to each other.
in clutter folder
hcdev -execpath=$HOME/.holochaindev1 -DHTport=6001 -agentID=agent3141 web 3141
hcdev -execpath=$HOME/.holochaindev2 -DHTport=6002 -agentID=agent4141 web 4141
hcdev -execpath=$HOME/.holochaindev3 -DHTport=6003 -agentID=agent5141 web 5141
if running all in one terminal you will need to kill the processes between restarts.
kill -kill `lsof -t -i tcp:3141` & kill -kill `lsof -t -i tcp:4141` & kill -kill `lsof -t -i tcp:5141`
When a branch is pushed to Github Travis runs a build. The build does the following:
- Installs docker-compose
- Runs docker-compose up -d which spins up a bootstrap server and 3 instances of clutter
- Installs the cypress dependencies
- Runs the Cypress e2e tests.
- If on master a new release is published to github releases. (coming soon)
- Set default handle from AgentID string
- Enable users to change their handle
- Share mews (tweets) -- up to 256 characters
- Follow someone (by specified handle)
- Unfollow someone
