appflow

Tools for generating graphs for application flow. So you can make a diagram of your application flow with dotviz, and then actually use it in your application.

Introduction

You write graphs (in dot format) that represent connectioning parts of an application.

digraph app {
        titleScreen -> mainMenu
        mainMenu -> singlePlayer
        mainMenu -> multiPlayer
        mainMenu -> settings

        singlePlayer -> game
        game -> quit
        quit -> mainMenu
}

You then instantiate the graph, providing implementations for nodes to link it to your application code.

You can then listen to changes in the graph.

const appflow = require('./lib/appflow')
const Graph = appFlow.Graph
const Race = appFlow.node.Race

const src = `
  digraph app {
          titleScreen -> mainMenu
          mainMenu -> singlePlayer
          mainMenu -> multiPlayer
          mainMenu -> settings

          singlePlayer -> game
          game -> quit
          quit -> mainMenu
  }
  `
const app = Graph.fromDot(src)
const nodes = {
  mainMenu: Race()
}
const startingNode = app.nodes.titleScreen
app.run(startingNode)
app.on('change',() => console.log(app.active)

How do these nodes work?
