Split text without spaces into list of words in Node.js

For my recent project, I need a trick to split strings contain English words to separate words. My stack is Node.js and no packages have been developed for my need.

For example, I need this string "youneedtolearnfromyourmistakes" split to words "You Need To Learn From Your Mistakes".

For this reason, I began searching for the development of a package for my need. And finally, with some open source project, I develop a package for split strings to words. The package called "wordsninja" has been released.

https://github.com/parsakafi/wordsninja
https://npmjs.com/package/wordsninja

Install

npm install wordsninja --save

Load package

const WordsNinjaPack = require('wordsninja');
const WordsNinja = new WordsNinjaPack();

Load dictionary

await WordsNinja.loadDictionary(); // First load dictionary

Add word(s)

WordsNinja.addWords('new word');

Parameters

• word: The word(s) (string|array)

Split sentence

let words = WordsNinja.splitSentence(string, {camelCaseSplitter, capitalizeFirstLetter, joinWords});

Parameters

• string: The string for split
• options
  • camelCaseSplitter: Split by Camel Case, Default is false (optional)
  • capitalizeFirstLetter: Capitalize First Letter, Default is false (optional)
  • joinWords: Return join words as sentence, Default is false (optional)

Example

(async () => {
    await WordsNinja.loadDictionary(); // First load dictionary
    let string = 'youneedtolearnfromyourmistakes';
    let words = WordsNinja.splitSentence(string);
    console.log(words);
})();

Result

[ 'you', 'need', 'to', 'learn', 'from', 'your', 'mistakes' ]

More options

let string = 'youneedtolearnfromyourmistakes';
let words = WordsNinja.splitSentence(string,
    {
        camelCaseSplitter: true,  // Frist camel case spliting
        capitalizeFirstLetter: true,  // Capitalize first letter of result
        joinWords: true  // Join words
    }
);
console.log(words);

Result

You Need To Learn From Your Mistakes

Add Word(s)

You can add new word(s) to dictionary in run-time

WordsNinja.addWords('Parsa');  // Add one word
WordsNinja.addWords(['Parsa', 'Kafi']); // Add one or more words

Example

let string = 'parsayouneedtolearnfromyourmistakes';
WordsNinja.addWords('Parsa');
let words = WordsNinja.splitSentence(string,
    {
        capitalizeFirstLetter: true,  // Capitalize first letter of result
        joinWords: true  // Join words
    }
);
console.log(words);

Result

Parsa You Need To Learn From Your Mistakes
