Codeflow is a visual programming platform built on top of Node.js™ that makes it easy for developers to build high performance, scalable back ends. Codeflow programs are inherently asynchronous and look like a graph, so it's easy to write complex, asynchronous code without any callback hell.

Codeflow programs are designed and tested using Codeflow designer. To download and setup the designer, please visit the downloads page.
Codeflow engine is the runtime component of Codeflow. Even though the designer comes with a latest version of the engine embedded to test and debug Codeflow programs, the engine can be also be installed directly and invoked from a command line, which is the typical way for running Codeflow applications in production.
$ sudo npm install -g codeflow
After installing the engine, Codeflow commands can be executed from a command line terminal as below:
codeflow [command] <options> <command params>
The run command is used to run a flow or entire project:
codeflow run <options> [path]
Where path can be a path to an individual flow, or the root folder of a Codeflow project. When the folder is passed, the project is started as whole, where all the trigger files inside the project are started by the engine automatically during startup. For more documentation visit the deployment guide.
Examples:
To run a single flow:
codeflow run hello.flw
Run a flow with an input JSON:
codeflow run -i '{"id": 1, "name": "Jack Sparrow"}' update.flw
Run a flow with an input JSON and print the output
codeflow run -i '{"age": 30}' calculate.flw -o
Start as project from the current directory
codeflow run .
Start as project from a specific path
codeflow run -w /path-to-project .
The install command is used to install a package
codeflow install <namespace/name@version>,<namespace/name@version>...
Example:
To install all the dependent packages, simply run install without any parameters at the project's root directory:
cd <project directory>
codeflow install
To install a specific package, run:
codeflow install codeflow/handlebars
To install a specific version of the package, append @<version>
:
codeflow install codeflow/handlebars@0.1.1
The uninstall command can be used to remove an unused package from the current project.
codeflow uninstall <namespace/name>,<namespace/name>...
