GraphQL Development in Leeds

Building GraphQL APIs for Leeds organisations, where the resolver model creates a performance trap that has nothing to do with the query language. Asking for fifty articles and each author issues fifty-one database queries by default — because each resolver runs independently and none of them knows the others are asking for something similar.

Why this comes up

The problem

One query returns quickly in testing and issues several hundred database queries against production data volumes.

What you get

What we deliver

  • Batching implemented so related lookups become one query rather than many
  • Query depth and complexity limited, since clients can otherwise request anything
  • Authorisation applied per field, because the schema exposes them individually
  • Errors returned in a way clients can act on rather than as a generic failure
  • Schema evolved by deprecation rather than by breaking existing consumers
  • Query performance monitored per operation, not as an aggregate for one endpoint

GraphQL Development in Leeds — common questions

Why does the query count explode?
Because each field resolves on its own. A list of items each needing a related record produces one query per item, and the framework has no way to know they could be fetched together unless you batch them deliberately.
How do we stop clients requesting too much?
Limit depth and complexity, and cost queries before running them. A flexible query language means a client can construct something expensive by accident, and without limits your API's load is determined by whoever is calling it.
Where does authorisation belong?
At the field level. A single query can traverse from an object a user may see to one they may not, so checking access at the entry point is insufficient — each field that exposes protected data has to make its own decision.
How should the schema change over time?
By adding and deprecating rather than removing. Clients hold their own queries, so a removed field breaks them without warning — deprecation lets you see who is still using something before it disappears.
Do you work with businesses across West Yorkshire?
Yes. We are based in Leicester, United Kingdom and work with clients throughout Yorkshire & the Humber, including Leeds and the surrounding West Yorkshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of Leeds businesses do you usually work with?
Financial, legal and health clients dominate, so the work almost always carries compliance, audit and data-handling requirements from day one. Beyond that we work across Financial & Legal Services, Healthcare & Digital Health, Retail and Higher Education.
Do you cover the areas around Leeds?
Yes — we work throughout Yorkshire & the Humber, including Sheffield, Manchester, York, Newcastle. Leeds is an urban area of roughly 800,000+, and we take on work across the wider West Yorkshire region rather than the city boundary alone.
