Markov chain text generator

Installation

You can install it from npm npm install js-markov-chain
Or clone this repository and require('./markov.js');

Usage

Firstly, require the package const Markov = require('js-markov-chain');
Secondly, initiate the chain:
const trainData = require('fs').readFileSync('data.txt', 'utf8');
const myChain = new Markov(trainData);
Data should be a string or an array of strings
You can add a string or an array of strings to chain using myChain.add(string);
Then, generate the text with string length limit:
myChain.generate(50);
Or, you can generate the text with default length up to 150 symbols:
myChain.generate();

Save and load the chain

Chain preparation can take a long time, so sometimes it would be better to load already built chain.
You can save the chain to file:
myChain.save('mychain.json');
You can load the chain from file:
myChain.load('mychain.json');
You may load messages from Telegram exported JSON (Export chat history - JSON). First argument is filename, second - name of the user whose messages you want to use.
myChain.loadTelegram('result.json', 'John Smith');
