x2y SDK for Node.js & TypeScript
The X2Y Dev Tools SDK is a comprehensive solution for modern software development, combining powerful API monitoring capabilities with intelligent code refactoring. It is designed for developers who want to improve their API integration practices and code quality through automated analysis and suggestions — every operation executed locally, with zero external network overhead.
npm install x2y-dev-tools-sdkWhat is inside
Five engines, one zero-dependency module
Engineered to solve specific, high-impact problems in heavy-load systems and legacy codebases. Explore each capability in the technical deep-dive.
Statistical Predictive Analytics
Mean, standard deviation and coefficient-of-variation analysis over response times, with dynamic confidence scoring (50–98%) and low / medium / high risk levels.
Heuristic Static Analysis
Scoped, line-by-line traversal with brace-matching. Detects N+1 queries, DOM thrashing and repeated allocations; returns exact corrected snippets.
Async Modernization
Detects nested .then() chains and callback hell, generating flattened async/await syntax aligned with modern ECMAScript standards.
In-Memory Telemetry
Append-only, optimized in-memory indexing of thousands of request records per second without blocking the Node.js event loop.
Rate-Limit Heuristics
Parses x-ratelimit headers, computes live usage percentage and injects suggestedAlternatives before 429 errors begin.
Playground
Execute the exact v1.0.4 release-gate validation suite — unified script, exact engine output, and a full decision breakdown.
SEO coverage
Documentation built for humans, crawlers and social previews
This project ships as a multi-page static documentation site instead of a hash-based single-page app, improving crawlability, canonical URLs, metadata control, internal linking, sitemap coverage and share previews for every documentation route.
Dedicated HTML per route
Every core section — installation, usage, features, docs, playground, contact and legal — has its own crawlable page with unique titles, descriptions and canonical URLs.
Structured data
WebSite, WebPage, BreadcrumbList, SoftwareSourceCode and FAQ schema help search engines understand the package, documentation IA and key questions.
Technical SEO files
robots.txt, sitemap.xml, a web manifest, a branded OG image, icon assets and a 404 page are generated as part of the project.
Frequently asked questions
Quick answers for evaluators and integrators
These are the questions technical buyers, maintainers and engineering teams usually ask before adopting the SDK.
Does the x2y SDK send any source code or traffic data to external servers?
No. The SDK is local-first and zero-telemetry by design. Traffic records, source code and analysis stay inside your own runtime unless you explicitly export them yourself.
Which runtimes does the SDK support?
The current stable target is Node.js 18 or newer, with Node.js 20+ recommended for the best developer ergonomics and performance.
Can I use the SDK in TypeScript without installing extra type packages?
Yes. Native type definitions ship with the package, so TypeScript projects get IntelliSense and type safety without separate @types dependencies.
Is the playground running live production code?
The playground demonstrates the exact release-gate fixtures and expected outputs used to validate v1.0.4. It is deterministic, local and safe to inspect.
