GraphQL API development

One endpoint, and clients ask for exactly the fields they need — which is powerful, and needs guarding.

API style

Chosen per project

Maintainable handover

GraphQL earns its place when several different clients need different shapes of the same data. A mobile list view wants three fields; a desktop detail view wants forty; with REST that becomes either over-fetching or a growing family of near-duplicate endpoints.

It moves work rather than removing it. The server must now defend against expensive queries, avoid the N+1 problem when resolving nested fields, and think about caching, which HTTP no longer does for you.

What we build with GraphQL

One backend serving web, mobile and partner clients with different needs

Interfaces that aggregate several services into a single view

Front-end teams iterating quickly without a backend change per screen

Reducing round trips on slow mobile connections

Where it fits — and where it does not

Good fit when

Multiple clients with divergent data requirements

Deeply related data fetched in one request

Teams that can own a schema as a shared contract

Consider something else when

Simple CRUD with one client — REST is less machinery

Public APIs where HTTP caching and CDN behaviour matter

Heavy file upload and download flows

Choosing

GraphQL or REST?

A real comparison rather than a preference. Both are correct answers to different questions.

Many client shapes

GraphQL — each asks for what it needs.

Public integration

REST — every partner already speaks it.

Deep related data

GraphQL — one round trip instead of five.

Cacheable content

REST — HTTP caching works out of the box.

How we work with GraphQL

Schema as the contract

The schema is designed and reviewed as a product interface, not generated automatically from database tables.

Batched resolvers

DataLoader-style batching so nested fields do not turn into hundreds of database queries.

Cost limits

Query depth and complexity limits, plus persisted queries for public clients, so one request cannot exhaust the server.

Field-level authorisation

Permissions enforced per field, because a flexible query language means clients will ask for everything.

Our typical GraphQL setup

Typical GraphQL stack choices and what we use for each
ConcernWhat we use
ServersApollo Server, or the GraphQL implementation native to the stack
PerformanceBatched and cached resolvers to defeat N+1
SafetyDepth and complexity limits, persisted queries
AuthorisationPer-field checks, not just per-endpoint
ToolingSchema in version control, breaking-change checks in CI

Frequently asked questions

No — it is different. It is better when several clients need different slices of related data, and worse when you want plain HTTP caching and universal partner compatibility.

Without limits, yes, which is why depth and complexity limits go in from the start, and public clients use persisted queries rather than arbitrary ones.

Yes, and it is a common first step. The schema resolves to existing services, which keeps the change contained.
