graphql-json-resolvers

Configure resolvers through JSON configuration rather than code

Configuring Resolvers

Resolver options are written in Velocity (via the velocityjs package). Resolver arguments and the process.env object are available as variables in the options.

$obj
$args
$ctx
$info
$env = process.env

See examples for usage examples.

Usage

import { compile } from 'graphql-json-resolvers'
import { addResolveFunctionsToSchema } from 'graphql-tools'

...

addResolveFunctionsToSchema(schema, compile(path.resolve(__dirname, './resolvers')))
