GraphQL Resolvers is a lightweight functional composition library for GraphQL resolvers (v0.4.2, last released 2019, no active maintenance). It provides utilities like combineResolvers, pipeResolvers, allResolvers, and skipResolvers to combine resolver functions in sequence, supporting access control and reusable middleware patterns. Unlike OOP alternatives like apollo-resolvers, it follows a pure functional paradigm similar to recompose but for GraphQL. The library has minimal dependencies and is designed to work with any GraphQL server. However, it is essentially unmaintained since 2019 and may lack updates for current GraphQL ecosystem changes.

Install & Compatibility

Where this runs

No compatibility data collected yet for this library.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

combineResolvers

✓ import { combineResolvers } from 'graphql-resolvers';

✗ const combineResolvers = require('graphql-resolvers').combineResolvers;

ESM and CJS both work in supported environments; avoid default import - there is no default export.

pipeResolvers

✓ import { pipeResolvers } from 'graphql-resolvers';

✗ import pipeResolvers from 'graphql-resolvers';

pipeResolvers is a named export; never default import.

allResolvers

✓ import { allResolvers } from 'graphql-resolvers';

✗ const all = require('graphql-resolvers').all;

The exported name is exactly 'allResolvers', not 'all'.

skipResolvers

✓ import { skipResolvers } from 'graphql-resolvers';

Shows how to compose two resolvers using combineResolvers: first checks authentication, then resolves data.

import { combineResolvers } from 'graphql-resolvers'; const isAuthenticated = (parent, args, { user }) => { if (!user) throw new Error('Not authenticated'); return user; }; const resolveSomething = (parent, args, { db }) => { return db.findSomething(); }; const resolver = combineResolvers( isAuthenticated, resolveSomething ); export default resolver;

Debug

Known issues

breakingThe package has no default export; only named exports are available.

fix

Use named imports like import { combineResolvers } from 'graphql-resolvers';

affects: >=0.0.0

gotchacombineResolvers chains resolvers sequentially but does not pass the return value of one resolver to the next as parent; each receives the original parent.

fix

Use pipeResolvers if you need to pass transformed parent values between resolvers.

affects: >=0.0.0

deprecatedThe library is no longer actively maintained; author has not released updates since 2019.

fix

Consider migrating to graphql-middleware or graphql-resolver-wrapper for long-term support.

affects: >=0.4.0

gotchaallResolvers only works correctly if each resolver returns a value that can be awaited (Promise or scalar); it does not short-circuit on falsy.

fix

Use allResolvers only when you expect all resolvers to pass; otherwise use combineResolvers with error throwing.

affects: >=0.0.0

Errors

Common errors & fixes

TypeError: graphql_resolvers_1.default is not a function

Assuming default export exists.

fix

Use named import: import { combineResolvers } from 'graphql-resolvers';

Cannot read property 'combineResolvers' of undefined

Using require('graphql-resolvers').combineResolvers incorrectly in some bundler setups that only support ESM.

fix

Use import { combineResolvers } from 'graphql-resolvers'; or require('graphql-resolvers').combineResolvers (CommonJS compatible).

Error: skip is not a function

Trying to use skipResolvers as 'skip' or 'skipResolver'.

fix

Import with correct name: import { skipResolvers } from 'graphql-resolvers';
