npm install crfsuite --save

CRFSuite Tagger

const crfsuite = require('crfsuite')
const tagger = crfsuite.Tagger()

let is_opened = tagger.open('./path/to/crf.model')
console.log('File model is opened:', is_opened)

let tags = tagger.tag(input)
console.log('Tags: ', tags)

CRFSuite Trainer

const path = require('path')
const crfsuite = require('crfsuite')
const trainer = crfsuite.Trainer()

let model_filename = path.resolve('./model.crfsuite')

let xseq = [['walk'], ['walk', 'shop'], ['clean', 'shop']]
let yseq = ['sunny', 'sunny', 'rainy']

// submit training data to the trainer
trainer.append(xseq, yseq)
trainer.train(model_filename)

// output: ./model.crfsuite
