Steemit.com

Steemit.com is the react.js web interface to the world's first and best blockchain-based social media platform. It uses STEEM, a blockchain powered by Graphene 2.0 technology to store JSON-based content for a plethora of web applications.

Why would I want to use Steemit.com?

• Learning how to build blockchain-based web applications using STEEM as a content storage mechanism in react.js
• Reviewing the inner workings of the steemit.com social media platform
• Assisting with software development for steemit.com

Installation

Clone the repository and make a tmp folder

git clone https://github.com/steemit/condenser
cd condenser
mkdir tmp

Verify NVM is installed

command -v nvm # verify

It should output "nvm". If it does not, install nvm.

Install dependencies

# Install at least Node v6.3 if you don't already have it ([NVM](https://github.com/creationix/nvm) recommended)
nvm install v6

npm install
npm install -g babel-cli

Create config file

cd config
cp default.json steem-dev.json

Generate a new crypto_key and save under server_session_secret in ./steem-dev.json.

node
> crypto.randomBytes(32).toString('base64')
> .exit

(note: it's steem.json in production)

Install mysql server

OS X:

brew update
brew doctor
brew upgrade
brew install mysql
mysql.server restart

Debian based Linux:

sudo apt-get update
sudo apt-get install mysql-server

On Ubuntu 16.04+ you may be unable to connect to mysql without root access, if so update the mysql root user as follows::

sudo mysql -u root
DROP USER 'root'@'localhost';
CREATE USER 'root'@'%' IDENTIFIED BY '';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%';
FLUSH PRIVILEGES;

Now launch mysql client and create steemit_dev database:

mysql -u root
> create database steemit_dev;
> quit

Create a password for the root mysql account:

mysql_secure_installation

(answer all it's questions as No, with Enter key, except to add a password, use "password")

Install sequelize-cli globally:

npm install -g sequelize sequelize-cli pm2 mysql

Edit the following files and make these changes:

Edit ~/condenser/db/config/config.json and save the mysql password under "password".

Edit ~/condenser/config/default.json and enter this string for database:

"database_url": "mysql://root:password@127.0.0.1/steemit_dev"

Edit `~/condenser/.babelrc if it doesn't look like the following:

{

"presets": ["es2015", "stage-0", "react"],

"plugins": ["transform-runtime", "transform-decorators-legacy"]

}

IMPORTANT: Add an env var for the database as well in your shell:

touch ~/.bash_profile edit this file, add 1 line:

export SDC_DATABASE_URL="mysql://root:password@localhost/steemit_dev"

source ~/.bash_profile

globally install sql2:

npm i -g mysql2

Run sequelize db:migrate in db/ directory.

Install Tarantool - Production Only

OS X:

brew install tarantool

Debian based Linux:

sudo apt-get install tarantool

Test the interactive console:

user@example:~$ tarantool

Development

npm start

It will take a few moments to launch. Once it says "Application started on port ####", you now have your development front end running at localhost:####, connected to the main public steem blockchain. You don't need to run steemd locally, by default you will connect to ws://node.steem.ws. Use your regular account name and credentials to login -- there is no separate dev login.

Style Guides

File naming and location

• Prefer CamelCase js and jsx file names
• Prefer lower case one word directory names
• Keep stylesheet files close to components
• Component's stylesheet file name should match component name

Js & Jsx

We are using Airbnb JavaScript Style Guide with some modifications (see .eslintrc). Please run eslint in the working directory before committing your changes and make sure you didn't introduce any new styling issues.

CSS & SCSS

If component requires a css rule, please use its uppercase name for the class, e.g. "Header" class for the header's root div. We adhere to BEM methodology with exception for Foundation classes, here is an example for the Header component:

<!-- Block -->
<ul class="Header">
  ...
  <!-- Element -->
  <li class="Header__menu-item">Menu Item 1</li>
  <!-- Element with modifier -->
  <li class="Header__menu-item--selected">Element with modifier</li>
</ul>

Production

If you want to test it locally in production mode, just run the following commands:

npm run build
npm run prod

or via pm2:

npm run build
npm -i -g pm2 # one time
pm2 start config/process.json
