Nitrous is the customized condenser (see below) that integrates with the Steem Engine Token Scotbot.
The instructions below are still accurate, but you need a few things to configure.
src/app/client_config.js collects most of the settings that are necessary to configure.
SDC_UPLOAD_IMAGE_URL can be set to
https://steemitimages.com (eventually this dependency should be changed).
SDC_IMAGE_PROXY-PREFIX may also
need a trailing
src/app/assets/images/favicons with your own, and also change
Condenser is the react.js web interface to the world's first and best blockchain-based social media platform, steemit.com. It uses STEEM, a blockchain powered by DPoS Governance and ChainBase DB to store JSON-based content for a plethora of web applications.
We highly recommend using docker to run condenser in production. This is how we run the live com site and it is the most supported (and fastest) method of both building and running condenser. Configuration settings can be set using environment variables (see configuration section below for more information). If you need to install docker, you can get it at https://get.docker.com
To modify, build, and run condenser using docker, it's as simple as pulling in the github repo and issuing one command to build it, like this:
git clone https://github.com/eonwarped/nitrous cd nitrous docker build -t="myname/condenser:mybranch" . docker run -it -p 8080:8080 myname/condenser:mybranch
Building from source without docker (the 'traditional' way):
(better if you're planning to do condenser development)
Clone the repository and make a tmp folder
git clone https://github.com/eonwarped/nitrous cd nitrous mkdir tmp
Install at least Node v8.7 if you don't already have it. We recommend using
nvm to do this as it's both the simplest way to install and manage
installed version(s) of node. If you need
nvm, you can get it at
Condenser is known to successfully build using node 8.7, npm 5.4.2, and yarn 1.3.2.
Using nvm, you would install like this:
nvm install v8.7
We use the yarn package manager instead of the default
npm. There are
multiple reasons for this, one being that we have
steem-js built from
source pulling the github repo as part of the build process and yarn
supports this. This way the library that handles keys can be loaded by
commit hash instead of a version name and cryptographically verified to be
exactly what we expect it to be. Yarn can be installed with
afterwards you will not need to use
npm install -g yarn yarn global add babel-cli yarn install --frozen-lockfile yarn run build
To run condenser in production mode, run:
yarn run production
When launching condenser in production mode it will automatically use 1 process per available core. You will be able to access the front-end at http://localhost:8080 by default.
To run condenser in development mode, run:
yarn run start
It will take quite a bit longer to start in this mode (~60s) as it needs to build and start the webpack-dev-server.
By default you will be connected to steemit.com's public steem node at
https://api.steeemit.com. This is actually on the real blockchain and
you would use your regular account name and credentials to login - there is
not an official separate testnet at this time. If you intend to run a
full-fledged site relying on your own, we recommend looking into running a
steemd locally instead
Debugging SSR code
yarn debug will build a development version of the codebase and then start the
local server with
--inspect-brk so that you can connect a debugging client.
You can use Chromium to connect by finding the remote client at
The intention is to configure condenser using environment variables. You
can see the names of all of the available configuration environment
config/custom-environment-variables.json. Default values are
Environment variables using an example like this:
export SDC_CLIENT_STEEMD_URL="https://api.steemit.com" export SDC_SERVER_STEEMD_URL="https://api.steemit.com"
Keep in mind environment variables only exist in your active session, so if
you wish to save them for later use you can put them all in a file and
source them in.
If you'd like to statically configure condenser without variables you can
edit the settings directly in
config/production.json. If you're running
in development mode, copy
cp config/production.json config/dev.json and adjust settings in
If you're intending to run condenser in a production environment one
configuration option that you will definitely want to edit is
server_session_secret which can be set by the environment variable
SDC_SESSION_SECRETKEY. To generate a new value for this setting, you can
node > crypto.randomBytes(32).toString('base64') > .exit
Style Guides For Submitting Pull Requests
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 use prettier to autofromat the
code, with this configuration. Run
yarn run fmt to format
yarn exec -- prettier --config .prettierrc --write src/whatever/file.js for a specific file.
CSS & SCSS
If a 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>
yarn run storybook
Run test suite
Test endpoints offline
If you want to test a server-side rendered page without using the network, do this:
yarn build OFFLINE_SSR_TEST=true NODE_ENV=production node --prof lib/server/index.js
This will read data from the blobs in
api_mockdata directory. If you want to use another set of mock data, create a similar directory to that one and add an argument
OFFLINE_SSR_TEST_DATA_DIR pointing to your new directory.
