A serious PHP bug called PHP2Shell was disclosed on 21 October 2026, and Cloudflare reported attacks soon after. Any server on PHP 8.1 or older is stuck with it, because the official fix only covers PHP 8.2 and later. Don't worry: we can rebuild your PHP back end as a lean Express.js API in 7 days. Read the PHP2Shell report.
Our PHP to Express.js migration services in USA and UK businesses ask for suit teams that want a small, fast JavaScript back end without a heavy framework. Express is the minimal web framework for Node.js: a router, a middleware chain and very little else. You add only the pieces your app needs, which keeps the codebase short and easy to follow.
That fits a lot of PHP apps we see. Many are a few dozen scripts that read a request, query MySQL and return HTML or JSON. In Express, each of those scripts becomes a route handler, shared checks such as login or rate limiting become middleware, and the result is a single readable entry file plus tidy route modules.
We are a web development team in India with more than a decade of experience, and we work hours that suit clients in the United States and the United Kingdom. You get a fixed price, a short daily update and an Express 5 app running on a supported Node.js LTS.
Why pick Express.js for the rewrite
Express does not tell you how to lay out every folder. For a small team that wants to move quickly and keep things simple, that freedom is the point.
Tiny learning curve
Any JavaScript developer can read an Express route in minutes. There are no decorators, no code generation and no framework rules to memorise.
Pick your own parts
Use Helmet for security headers, express-session or JWT for login, Zod for validation and Knex or Prisma for the database, and leave out anything you do not need.
Middleware for everything
Logging, CORS, compression and auth slot in as plain functions, and thousands of ready Express middleware packages exist on npm.
What we rebuild in Express.js
- Each PHP script or controller turned into an Express route handler
- Shared include files rewritten as reusable middleware
- Your existing MySQL or PostgreSQL database, accessed through Knex or Prisma
- Server-rendered pages with EJS or Pug, or a clean JSON API for your front end
- Login with express-session or JWT, keeping existing bcrypt passwords
- Input checks with Zod or express-validator on every route
- Security headers with Helmet and rate limits on login and forms
- PM2 or Docker deployment with logs and automatic restarts
From PHP to Express.js in 7 days
Day 1: List every endpoint
We map each PHP file to the URL it serves, note the queries and outside calls it makes, and agree a fixed price.
Days 2-4: Write routes and middleware
We set up Express 5, connect your database, and port the endpoints group by group with validation on each one.
Days 5-6: Match the old responses
We send the same requests to the PHP app and the Express app and compare the output, then you test on staging.
Day 7: Switch traffic
Your domain moves to Express behind Nginx, the PHP server stays on standby, and we keep an eye on logs.
Plain PHP vs Express.js
Both are light, which is why Express often feels familiar to teams leaving hand-written PHP.
| PHP scripts | Express.js | |
|---|---|---|
| Routing | One file per URL, or .htaccess rewrites | app.get and app.post routes grouped in routers |
| Shared logic | include and require at the top of each file | Middleware functions run in order |
| Input checks | Hand-written if statements | Zod or express-validator schemas |
| Async work | Blocking calls one after another | async and await without blocking other users |
| Structure | Whatever grew over time | Small, flexible, decided by your team |
| Best fit | Legacy sites | Lean APIs and small to mid-sized web apps |
Why our team for an Express rewrite
Minimal frameworks are only pleasant when the code stays tidy. We set a simple folder plan on day one so your Express app does not become another tangle of files.
Honest about when Express is too small
If your app has many modules and several developers, a structured framework like NestJS may serve you better, and we will recommend it in the audit.
One fixed price, agreed in writing after the audit.
NDA signed on the first call, before any code is shared.
Express.js migration for USA and UK teams
This service is a good match for small and mid-sized businesses in the United States and United Kingdom that want a lighter JavaScript back end in place of ageing PHP. Our hours overlap the US Eastern morning and the UK afternoon, and we answer every message the same day.
With an offshore team the cost stays well below what a local agency would charge, and you still work with one manager, an NDA and a fixed price.

Frequently asked questions
Straight answers about our PHP to Express.js Migration service.
A small or medium PHP app usually moves to Express.js in 7 days, including audit, rebuild, testing and launch. For very large apps we agree a phased plan, and the first phase goes live inside those 7 days.
Yes. Express 5 is the current major release, it runs on supported Node.js versions, and it remains the most widely used Node web framework. Its simplicity is the reason teams keep picking it.
Express is minimal and leaves structure to you. NestJS is built on top of Express by default and adds modules, dependency injection and TypeScript conventions. Small teams often prefer Express, larger teams NestJS.
Yes. We connect Express to your existing MySQL or PostgreSQL database, so no data needs converting. Tables can be tidied later, once the new app is live and stable.
It does once the PHP server is switched off, because the app no longer runs on PHP at all. We also add Helmet, rate limiting and input validation to the Express app.
Yes. We plan our working day around clients in the USA and the UK, reply the same day, sign an NDA and quote a fixed price.
Is your PHP app still on an old version?
