Cloudflare Workers Development in Cardiff
Building on Cloudflare Workers for Cardiff organisations, where the runtime is not Node despite the JavaScript. Workers run on isolates with web platform APIs, so a package depending on Node's filesystem, networking or crypto modules simply will not run — and that constraint decides what can be ported and what has to be rewritten.
Why this comes up
The problem
An existing Node service was moved to Workers and half its dependencies rely on modules that do not exist.
What you get
What we deliver
- Dependencies assessed against the runtime before any port is committed to
- CPU time limits respected, since Workers are not intended for long computation
- State handled through the appropriate storage rather than held in memory
- Cold start and distribution behaviour understood, as execution happens near users
- Bindings configured for storage, queues and secrets rather than environment hacks
- Local development and deployment established so releases are repeatable

Working in Cardiff
Wales
Cardiff has a significant broadcast and media sector alongside a large public-sector presence, and Welsh-language provision is a genuine requirement on public-facing work here rather than a nice-to-have.
Public sector and broadcast work is common, and bilingual provision is usually a requirement rather than an option.

Cloudflare Workers Development in Cardiff — common questions
- Why do Node packages fail?
- Because the runtime is different. Workers implement web platform APIs rather than Node's, so anything reaching for the filesystem, raw sockets or Node-specific crypto has no equivalent — compatibility flags cover some of it, and the rest needs replacing.
- What are Workers genuinely good for?
- Short work close to the user. Request rewriting, authentication checks, personalisation, API composition and edge caching all suit the model, whereas anything computationally heavy or long-running fits badly and is better placed elsewhere.
- Where does state live?
- In the platform's own storage rather than in the Worker. Instances are created and discarded across locations, so anything held in memory disappears unpredictably — which surprises teams porting a service that quietly relied on a local cache.
- Should we move an entire service here?
- Rarely all of it. Workers work best in front of something rather than as a replacement for everything, so the productive pattern is moving the parts that benefit from running near users and leaving the rest where it already works.
- Do you work with businesses across Cardiff?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including Cardiff and the surrounding Cardiff area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Cardiff businesses do you usually work with?
- Public sector and broadcast work is common, and bilingual provision is usually a requirement rather than an option. Beyond that we work across Media & Broadcasting, Financial Services, Public Sector, Higher Education and Sport.
- Do you cover the areas around Cardiff?
- Yes — we work throughout Wales, including Bristol, Swansea. Cardiff is an urban area of roughly 490,000+, and we take on work across the wider Cardiff region rather than the city boundary alone.
