Usage

Basic Usage

Glin-Profanity now provides framework-agnostic core functions alongside React-specific hooks:

🟢 Node.js / Vanilla JavaScript

const { checkProfanity } = require('glin-profanity');

const text = "This is some bad text with damn words";
const result = checkProfanity(text, {
  languages: ['english', 'spanish'],
  replaceWith: '***'
});

console.log(result.containsProfanity); // true
console.log(result.profaneWords);      // ['damn']
console.log(result.processedText);     // "This is some bad text with *** words"

🔷 TypeScript

import { checkProfanity, ProfanityCheckerConfig } from 'glin-profanity';

const config: ProfanityCheckerConfig = {
  languages: ['english', 'spanish'],
  severityLevels: true,
  autoReplace: true,
  replaceWith: '🤬'
};

const result = checkProfanity("inappropriate text", config);

Framework Examples

⚛️ React

import React, { useState } from 'react';
import { useProfanityChecker, SeverityLevel } from 'glin-profanity';

const App = () => {
  const [text, setText] = useState('');
  
  const { result, checkText } = useProfanityChecker({
    languages: ['english', 'spanish'],
    severityLevels: true,
    autoReplace: true,
    replaceWith: '***',
    minSeverity: SeverityLevel.EXACT
  });

  return (
    <div>
      <input value={text} onChange={(e) => setText(e.target.value)} />
      <button onClick={() => checkText(text)}>Scan</button>
      
      {result && result.containsProfanity && (
        <p>Cleaned: {result.processedText}</p>
      )}
    </div>
  );
};

💚 Vue 3

<template>
  <div>
    <input v-model="text" @input="checkContent" />
    <p v-if="hasProfanity">{{ cleanedText }}</p>
  </div>
</template>

<script setup>
import { ref } from 'vue';
import { checkProfanity } from 'glin-profanity';

const text = ref('');
const hasProfanity = ref(false);
const cleanedText = ref('');

const checkContent = () => {
  const result = checkProfanity(text.value, {
    languages: ['english'],
    autoReplace: true,
    replaceWith: '***'
  });
  
  hasProfanity.value = result.containsProfanity;
  cleanedText.value = result.autoReplaced;
};
</script>

🔴 Angular

import { Component } from '@angular/core';
import { checkProfanity, ProfanityCheckResult } from 'glin-profanity';

@Component({
  selector: 'app-comment',
  template: `
    <textarea [(ngModel)]="comment" (ngModelChange)="validateComment()"></textarea>
    <div *ngIf="profanityResult?.containsProfanity" class="error">
      Please remove inappropriate language
    </div>
  `
})
export class CommentComponent {
  comment = '';
  profanityResult: ProfanityCheckResult | null = null;

  validateComment() {
    this.profanityResult = checkProfanity(this.comment, {
      languages: ['english', 'spanish'],
      severityLevels: true
    });
  }
}

🚂 Express.js Middleware

const express = require('express');
const { checkProfanity } = require('glin-profanity');

const profanityMiddleware = (req, res, next) => {
  const result = checkProfanity(req.body.message || '', {
    languages: ['english'],
    autoReplace: true,
    replaceWith: '[censored]'
  });
  
  if (result.containsProfanity) {
    req.body.message = result.autoReplaced;
  }
  
  next();
};

app.post('/comment', profanityMiddleware, (req, res) => {
  // Message is now sanitized
  res.json({ message: req.body.message });
});
