System Architecture Overview

NLPinSEO.com is built as an ultra-fast, statically-optimized **Next.js 15 App Router** application with full **TypeScript** type checking.

To achieve maximum SEO crawl-budget performance and core web vitals speed, all text calculations, regex parsers, and node map mappings compile as modular **client-side TypeScript objects**. This enables immediate execution inside the client browser playground without relying on heavy external API roundtrips.

How to Add a New Tool in 3 Steps

Integrating a new text diagnostic or semantic auditor is simple and modular:

1. Create the Analyzer Calculations file:

   Add your string processing or scoring equations file in /lib/analyzers/myanalyzer.ts:

   export const MyAnalyzer = {
     run(text: string, title: string) {
       // Custom regex or mathematical models here
       const score = Math.round(50 + Math.abs(Math.sin(text.length)) * 40);
       return { title, score };
     }
   };

2. Register inside the loader catalog:

   Map your new analyzer inside the central registry /lib/analyzers/registry.ts:

   import { MyAnalyzer } from "./myanalyzer";
   
   export const ANALYZER_REGISTRY = {
     // Add entry:
     "my-custom-tool": {
       id: "my-custom-tool",
       name: "My Custom Scorer",
       category: "seo-ai-optimization",
       run: MyAnalyzer.run
     }
   };

3. Append attributes to the database catalog:

   Include descriptions, difficulty badges, input requirements, and priority flags inside /data/tools.ts. The dynamic route will automatically pre-render the matching pages!

Under the Hood: Mathematical Models

Score(D, Q) = ∑ [ IDF(qi) · (f(qi, D) · (k1 + 1)) / (f(qi, D) + k1 · (1 - b + b · (|D| / avgdl))) ]

Cosine Similarity = (A · B) / (||A|| ||B||)
