text-categorizer

// Install the package npm install content-type-classifier

// Basic Usage import { ContentTypeClassifier } from 'content-type-classifier';

// Classify any text content const result = ContentTypeClassifier.categorize("your text here");

import { ContentTypeClassifier } from 'content-type-classifier';

// 1. Detecting Links const linkResult = ContentTypeClassifier.categorize("https://www.example.com"); console.log(linkResult); // Output: { // type: "link", // content: "https://www.example.com", // metadata: { links: ["https://www.example.com"] } // }

// 2. Detecting Code const codeResult = ContentTypeClassifier.categorize(function hello() { return "world"; }); console.log(codeResult); // Output: { // type: "code", // content: "function hello() {...}", // metadata: { codeLanguage: "javascript" } // }

// 3. Detecting Currency const currencyResult = ContentTypeClassifier.categorize("$1,234.56"); console.log(currencyResult); // Output: { // type: "currency", // content: "$1,234.56", // metadata: { amount: 1234.56, currency: "$" } // }

// 4. Detecting Social Posts const socialResult = ContentTypeClassifier.categorize("Check out #typescript with @johnsmith!"); console.log(socialResult); // Output: { // type: "social", // content: "Check out #typescript with @johnsmith!", // metadata: { // hashtags: ["#typescript"], // mentions: ["@johnsmith"] // } // }

// 5. Detecting CSV const csvResult = ContentTypeClassifier.categorize(name,age,city John,30,New York Jane,25,Boston); console.log(csvResult); // Output: { // type: "csv", // content: "name,age,city...", // metadata: { // structured: [ // { name: "John", age: "30", city: "New York" }, // { name: "Jane", age: "25", city: "Boston" } // ] // } // }

// 6. Error Handling try { const result = ContentTypeClassifier.categorize(""); console.log(result); } catch (error) { console.error("Failed to categorize content:", error); }

import { ContentTypeClassifier, ContentCategory } from 'content-type-classifier';

// With type checking function processContent(content: string): void { const result: ContentCategory = ContentTypeClassifier.categorize(content);

switch(result.type) {
    case 'link':
        console.log("Found links:", result.metadata?.links);
        break;
    case 'code':
        console.log("Code language:", result.metadata?.codeLanguage);
        break;
    case 'currency':
        console.log("Amount:", result.metadata?.amount);
        console.log("Currency:", result.metadata?.currency);
        break;
    // ... handle other types
}

}

// Processing multiple items const contents = [ "https://example.com", "$123.45", "const x = 42;", "#coding @typescript" ];

contents.forEach(content => { const result = ContentTypeClassifier.categorize(content); console.log(Content type: ${result.type}); console.log("Metadata:", result.metadata); });

The classifier supports these content types:

Links Code Lists Email JSON Markdown Equations Dates Social posts Search queries Phone numbers Addresses CSV data XML content SQL queries File paths Currency amounts Product codes
