GraphQL Development in Colchester
Building GraphQL APIs for Colchester 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 Colchester — 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 Essex?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout East of England, including Colchester and the surrounding Essex area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Colchester businesses do you usually work with?
- Suppliers needing security and compliance evidence for public-sector and defence procurement, plus student-facing services. Beyond that we work across Public Sector, Defence, Higher Education, Retail and Agriculture.
- Do you cover the areas around Colchester?
- Yes — we work throughout East of England, including Chelmsford, Canterbury, London. Colchester is an urban area of roughly 190,000+, and we take on work across the wider Essex region rather than the city boundary alone.
