TypeError: Cannot read property 'removeStopwords' of undefined

Question

I am working on a project using stopwords and typescript and I am receiving the below error I have attempted to debug by removing the !string.trim() and replacing with string.trim() and I receive an output of

0 0

Also have attempted to give fixedSpelling a type of any and also the getSentiment(str:string | undefined) but no success..

// @ts-ignore
import aposToLexForm from "apos-to-lex-form";
import { WordTokenizer } from "natural";
// @ts-ignore
import SpellCorrector from 'spelling-corrector';
import stopword from "stopword";

const tokenizer = new WordTokenizer();
const spellCorrector = new SpellCorrector();
spellCorrector.loadDictionary();

function getSentiment(str: string): -1 | 0 | 1 {
    if (!str.trim()) {
        return 0;
    }

const lexed = aposToLexForm(str).toLowerCase().replace(/[^a-zA-Z\s]+/g, "");

const tokenized = tokenizer.tokenize(lexed);

const fixedSpelling = tokenized.map((word) => spellCorrector.correct(word));

const stopWordsRemoved = stopword.removeStopwords(fixedSpelling);

console.log(stopWordsRemoved);

return 0;

}

console.log(getSentiment('This is awesome!'))
console.log(getSentiment('Logging is super duper cool!'))

error being received -

Answer 1

It looks like 'stopword' does not have a default export. You could to change your import statement to:

import * as stopword from 'stopword'

Or without the stopword module:

import { removeStopwords } from 'stopword'
