Package Exports

ngraminator
ngraminator/dist/ngraminator.cjs.js
ngraminator/dist/ngraminator.esm.mjs
ngraminator/dist/ngraminator.umd.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (ngraminator) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

ngraminator

A really small ngram generator for Node.js and the browser. Check out the interactive demo.

Breaking change

How the library is now required is slightly different. For CommonJS it used to be const ngraminator = require('ngraminator'), but now it is const { ngraminator } = require('ngraminator')

And UMD used to be ngraminator(), but is now ngrm.ngraminator()

Initiation

CJS - CommonJS

const { ngraminator } = require('ngraminator')
// ngraminator(wordArray, ngramLenghtArray) available

ESM - Ecmascript Modules

import { ngraminator } from 'ngraminator'
// ngraminator(wordArray, ngramLenghtArray) available

Script tag

<script src="ngraminator.umd.js"></script>

<script>
// ngrm.ngraminator(wordArray, ngramLenghtArray) available
</script>

Usage

const str = "mary had a little lamb it's fleece"

// get ngrams of length 3
ngraminator(str.split(' '), [3])
// [
//   ['mary', 'had', 'a'],
//   ['had', 'a', 'little'],
//   ['a', 'little', 'lamb'],
//   ['little', 'lamb', 'it\'s'],
//   ['lamb', 'it\'s', 'fleece']
// ]

// get ngrams of lengths 1 and 2
ngraminator(str.split(' '), [1, 2])
// [
//   [ 'mary' ],
//   [ 'had' ],
//   [ 'a' ],
//   [ 'little' ],
//   [ 'lamb' ],
//   [ 'it\'s' ],

//   [ 'a', 'little' ],
//   [ 'little', 'lamb' ],
//   [ 'lamb', 'it\'s' ],
//   [ 'it\'s', 'fleece' ]
// ]

// get ngrams of lengths 1, 2, and 5
ngraminator(str.split(' '), [1, 2, 5])
// [
//   [ 'a' ],
//   [ 'a', 'little' ],
//   [ 'a', 'little', 'lamb', 'it\'s', 'fleece' ],
//   [ 'fleece' ],
//   [ 'had' ],

// ]
//

// get ngrams of lengths 1, 2, and 5 stringified
ngraminator(str.split(' '), [1, 2, 5]).map(item => item.join(' '))
// [
