React Dialogue Tree

React Dialogue Tree is a component for displaying a videogame-style dialog box on a web page or in a react app. It accepts and presents a dialogue written in the Yarn Language.

Under the hood, it uses Bondage.js. This repo also functions as an example of how to integrate Bondage.js into a component.

Installation


npm i -S react-dialogue-tree

Usage

If you want to use React Dialogue Tree in some component:

import React from 'react'
import DialogueTree from 'react-dialogue-tree'
import 'react-dialogue-tree/dist/react-dialogue-tree.css'

export default function SomeComponent (dialogue) {
  return <DialogueTree dialogue={dialogue} /> 
}

Props

dialogue (required if no "runner" prop): string - The Yarn dialogue to run. A .yarn file in string form.

runner (required if no "dialogue" prop): YarnBound - An existing YarnBound runner to use instead of instantiating a new one

startAt: string: - The title of the node to start the dialogue on.

  • default: "Start"

functions: object - An object containing custom functions to run when they are called in a yarn expression.

  • As the Yarn docs mention, these should not have side effects. They may execute at unexpected times.

variableStorage: object - A custom storage object with get() and set() functions (a new Map(), for instance.)

  • Unless you have a specific need you can omit this and use the built-in default.
  • One use is supplying variables with initial values, though you could also do that in the dialogue.

handleCommand: function - This will be called with the Command Result as the single argument (see below for the data structure), when the dialogue hits a command.

combineTextAndOptionsResults: boolean - If this is false, options nodes will be shown by themselves rather than combined with the text prompt before them.

  • default: true

onDialogueEnd: function - Will fire when the last node of the dialogue is reached, with no arguments.

defaultOption: string - User will click this to advance from a text line.

finalOption: string - User will click this to end the dialogue.

locale: string - Used for pluralization markdown attributes.

Styling

import 'react-dialogue-tree/dist/react-dialogue-tree.css'

or however else you like to manage your css.

Command Result

Generic commands in your story will call the handleCommand function with an object like this:

{
  "command": "someCommand",
  "hashtags": [],
  "metadata": {
    "title": "StartingNode",
    "someTag": "someTag",
    "filetags": [
      "someFiletag"
    ]
  }
}

        ===
      `
      ReactDOM.render(
        React.createElement(
          ReactDialogueTree.default, // "default" is important
          {dialogue},
        ),
        document.getElementById('root')
      )
