PHP2Shell, two critical PHP flaws (CVSS 9.2), was announced on October 21, 2026, alongside patched builds. An exploit attempt had been recorded four days before. Those builds cover PHP 8.2, 8.3, 8.4 and 8.5 only. A TypeScript rewrite takes the app off PHP altogether, and most small and mid-sized apps go live in 7 days. How PHP version updates work.
With PHP to TypeScript migration services, US companies run one typed language across the whole product. Your front end may already be React, Vue or Angular written in TypeScript. When the server speaks the same language, the shape of a customer, an order or an invoice is defined once and checked by the compiler on both sides.
Shared types remove a whole class of bugs. In a PHP back end with a JavaScript front end, a renamed field breaks the screen and nobody finds out until a user complains. With one typed codebase, the build fails before the change ships. Refactors become safer, editors autocomplete real data, and new developers learn the system by reading the types.
Techno Mantra is an AI and web development company that builds AI applications, websites, SEO programs and custom CRM systems for businesses in the US, Canada and Australia. You get a fixed price and a TypeScript codebase on Node.js with strict mode on.
What full-stack TypeScript gives you
TypeScript checks types before the code runs, across the browser and server in one pass. PHP has type hints too, but PHP enforces them only while the code runs.
Shared types, front to back
One package of types and Zod schemas is imported by both the API and the web app, so a change to the data model shows up everywhere it matters at compile time.
Fewer production surprises
Strict mode catches undefined values, wrong argument types and missing fields while you code, which in PHP can surface only as errors in the live log.
One hiring profile
You hire TypeScript developers who can work on any part of the product, instead of separate PHP and JavaScript roles.
The PHP to TypeScript scope
- PHP back end rewritten in TypeScript on Node.js with strict compiler settings
- A shared types package used by both server and front end
- Zod schemas for runtime validation that also generate the TypeScript types
- Database access through Prisma or Drizzle with typed query results
- Your existing MySQL or PostgreSQL data kept in place
- Typed API client for your React, Vue or Angular front end
- Login and sessions carried over, with current password hashes kept
- ESLint, Prettier and a CI build that blocks code with type errors
A 7-day TypeScript rewrite
Day 1: Model the data
Reading the PHP code and database yields TypeScript types for your main records, and the price gets fixed with you.
Days 2-4: Write typed services
A monorepo holds the new TypeScript server, built against your database, and the front end connects to the shared types.
Days 5-6: Type check and test
The compiler runs in strict mode with zero errors allowed, and automated tests compare results against the PHP app.
Day 7: Ship it
The TypeScript app deploys, traffic moves over, and the PHP version stays available until you are confident.
PHP types vs TypeScript types
Modern PHP has types too. What differs is when they are checked.
| PHP back end | TypeScript stack | |
|---|---|---|
| When types are checked | At runtime, when a line executes | At build time, before deployment |
| Front and back end | Two languages with separate data definitions | One language with shared type definitions |
| Renaming a field | Search and hope | Compiler lists every place to fix |
| API contract | Documented by hand | Imported as types by the client |
| Editor help | Good with static analysis tools | Autocomplete for every object and API response |
| Runs on | PHP-FPM or Apache | Node.js, and also Deno or Bun |
Why we are the right team for a TypeScript move
The developers write TypeScript daily on front-end and back-end projects, so shared types come first and the rest is built around them.
Types that match your real data
Types are generated from your actual database schema and API responses, so the compiler protects you from day one.
Price set in writing once the audit ends.
NDA on request before you grant code or data access.
TypeScript migration for US businesses
This service is intended for small and mid-sized businesses in the USA that want their web product written in one typed language. Calls overlap US Eastern mornings, and you get an answer inside one business day.
One project manager runs the rewrite for a team with 5,000+ projects delivered, and the full TypeScript codebase belongs to you.

Frequently asked questions
Straight answers about our PHP to TypeScript Migration service.
Most small and mid-sized PHP apps are rewritten in TypeScript in 7 days, from audit to launch. A large system is split into phases instead.
No. TypeScript is JavaScript with a type system, compiled to plain JavaScript. On the server it runs on Node.js, usually with a framework such as Express or NestJS, chosen for your app during the audit.
No, its types disappear after compiling, so Zod validates incoming data at the edges of the app and the TypeScript types are derived from the same schemas.
Yes. If your PHP app renders HTML with templates, the views can move to React or Next.js in TypeScript at the same time, so the shared types cover every screen.
Yes, from the moment the PHP server goes offline. PHP2Shell lives in the PHP engine, and a TypeScript app on Node.js does not use it. Node.js stays on a supported LTS version.
Yes. Teams on both sides of the Atlantic get meeting slots in US Eastern hours, an NDA if they ask and a fixed price.
Is your PHP app still on an old version?
Send the URL or repository, under NDA if needed. The audit checks for the PHP2Shell flaw and outdated code and shows what a 7-day migration looks like.
