No-nonsense tools and tutorials for UK developers
Every demo runs on office fibre; the 07:42 out of Brighton runs on hope. Here's how to build and test a script loader that copes with tunnels, captive portals and the great 4G scrum at Clapham Junction — and how to prove it works before you ship.
Public-sector fonts do not need to arrive all at once. Here is a practical loader pattern for UK teams: preload one critical weight, defer the rest, keep Welsh diacritics intact, and give the fallback enough metric cover to avoid a visible jolt.
Support teams do not need a browser full of random userscripts. They need a small, managed shelf of approved helpers that can be switched on, pinned and rolled back without waiting for a full app release. Here is how to build one with a signed manifest and CSP-friendly injection.
Ticket-site loaders usually collapse at 9am because they are built to look optimistic rather than be honest. This opinionated piece uses a festival-ticket drop to show how queueing, rate limits and graceful degradation can shed load fairly instead of pretending everyone is about to get in.
A registry wobble should not turn a two-person UK team into an incident response unit. This is a practical runbook for lockfile discipline, vendored tarballs, a local mirror and a tiny fallback loader that keeps CI shipping without a platform rewrite.
Deposit schemes, council tax rules, recycling calendars and opening hours all change at the border. This walkthrough builds a small loader that resolves a postcode area, pulls only the relevant config bundle, caches it hard at the edge and degrades sensibly when the lookup is down.
IE mode lives on in UK councils, NHS trusts and housing associations, and most build pipelines either ignore it or make every visitor pay for it. Here is a small, instrumented loader that keeps modern browsers on the fast path and gives you the numbers to retire the fallback with evidence.
Black Friday does not need a war room, but it does need a plan that survives a tired developer at 7am. This is the pre-flight checklist for a two-person UK retail team: cut the critical path, park the widgets, and rehearse the rollback before the traffic arrives.
You cannot change the vendor's loader, but you can stop it from owning your page. A practical, slightly opinionated guide to proxy loaders, feature detection, version pinning and kill switches, with a UK procurement brain on the side.
Daylight-saving transitions break naive cron jobs twice a year. Here is how to resolve UK wall-clock schedules safely, test the awkward Sundays, and keep background loaders predictable in both BST and GMT.
A bank holiday weekend is a load test with a skeleton crew. Here is how to warm caches, rehearse traffic, freeze deployments and build a rollback plan that makes Monday morning dull rather than dramatic.
Tag managers are convenient right up until you open the network tab. Here's the small, boring replacement we built for a UK marketing site: a sub-2 KB loader that handles ordering, consent gating and failure isolation — plus the performance budget that proved the swap was worth it.
A rotating circle tells a resident that something is happening. It doesn't tell them what, how long, or whether to keep waiting. Here's a practical playbook for perceived performance on UK public-sector sites — skeleton screens, honest progress, accessible status messages and cheap tests a two-person team can actually run.
You do not need to adopt a new meta-framework to get faster first loads. Here is the route-level splitting playbook we used on a small Bristol-built SaaS, including the loading states, the stale-chunk problem nobody warns you about, and the numbers we saw on Core Web Vitals afterwards.
Per-seat flag platforms are lovely until the invoice arrives and you notice you are shipping user identifiers to a US processor to decide whether a button is blue. A practical, slightly opinionated look at building a small self-hosted flag service with proper kill switches and UK GDPR-friendly defaults.
