Express Development in Coventry
Building with Express for Coventry organisations, where the minimalism means every decision is yours. That includes one that catches teams out repeatedly: an error thrown inside an asynchronous handler does not reach the framework's error handling by default, so the request hangs and the process may terminate rather than returning a sensible response.
Why this comes up
The problem
An async route throws, the client waits until it times out, and the only trace is a process restart in the logs.
What you get
What we deliver
- Asynchronous errors routed into the error handler rather than escaping it
- A single error handler producing consistent responses and useful logs
- Input validated at the boundary, since the framework validates nothing itself
- Security headers, rate limiting and body limits added deliberately
- Middleware order reviewed, as it determines behaviour more than it appears to
- Graceful shutdown implemented so in-flight requests complete on deployment

Working in Coventry
West Midlands
Coventry's automotive and mobility research base means a lot of local firms sit in complex supply chains, where the useful software is usually the piece that connects systems nobody planned to connect.
Supply chain integration dominates — connecting order, quality and delivery data between manufacturers and the tiers above and below them.

Express Development in Coventry — common questions
- Why do async errors behave differently?
- Because a rejected promise is not a thrown exception the framework can catch around your handler. Without a wrapper or explicit handling it escapes entirely, leaving the request unanswered and potentially bringing down the process depending on configuration.
- What does Express not give us?
- Validation, authentication, security headers, rate limiting and structured errors — all deliberately. That is the trade for its simplicity, and the risk is assuming a reasonable default exists where in fact nothing is happening at all.
- Does middleware order matter?
- Considerably. Middleware runs in the order registered, so a body parser after a route sees nothing, and error handling registered before routes never fires. Ordering problems produce behaviour that looks like a bug in unrelated code.
- Why implement graceful shutdown?
- So deployments do not drop requests. A process terminated immediately abandons whatever it was doing, and in a containerised environment that happens on every release — stopping new requests and finishing existing ones takes little code and removes a class of intermittent failure.
- Do you work with businesses across West Midlands?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout West Midlands, including Coventry and the surrounding West Midlands area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Coventry businesses do you usually work with?
- Supply chain integration dominates — connecting order, quality and delivery data between manufacturers and the tiers above and below them. Beyond that we work across Automotive, Advanced Manufacturing, Higher Education, Logistics and Gaming.
- Do you cover the areas around Coventry?
- Yes — we work throughout West Midlands, including Birmingham, Leicester, Northampton, Wolverhampton. Coventry is an urban area of roughly 370,000+, and we take on work across the wider West Midlands region rather than the city boundary alone.
