TBQ is a tool to run simple text-based adventures in node.js. Currently it has structure based on rooms containing objects that can be interacted with.

Create a data file (e.g. data.json), you can find format explanations in corresponding file. Then use the engine:

const TBQ = require('tbq');
const game = TBQ.createGame(require('data.json'));

do {
  var playerInput = /* Somehow get command entered by player */
  var actionResult = game.exec(playerInput);
  if (actionResult.text !== null) {
    /* Output actionResult.text to player */
  } else {
    /* Output some help */
  }
} while (!actionResult.end)

Each game.exec(playerInput) call returns { text, end } object (text property is null if command is invalid in given circumstances).
