Учитывая экземпляр GraphQLSchema (т.е. что возвращает makeExecutableSchema
) и ваш resolvers
объект, вы можете просто проверить его самостоятельно. Примерно так должно работать:
const { isObjectType, isWrappingType, isLeafType } = require('graphql')
assertAllResolversDefined (schema, resolvers) {
// Loop through all the types in the schema
const typeMap = schema.getTypeMap()
for (const typeName in typeMap) {
const type = schema.getType(typeName)
// We only care about ObjectTypes
// Note: this will include Query, Mutation and Subscription
if (isObjectType(type) && !typeName.startsWith('__')) {
// Now loop through all the fields in the object
const fieldMap = type.getFields()
for (const fieldName in fieldMap) {
const field = fieldMap[fieldName]
let fieldType = field.type
// "Unwrap" the type in case it's a list or non-null
while (isWrappingType(fieldType)) {
fieldType = fieldType.ofType
}
// Only check fields that don't return scalars or enums
// If you want to check *only* non-scalars, use isScalarType
if (!isLeafType(fieldType)) {
if (!resolvers[typeName]) {
throw new Error(
`Type ${typeName} in schema but not in resolvers map.`
)
}
if (!resolvers[typeName][fieldName]) {
throw new Error(
`Field ${fieldName} of type ${typeName} in schema but not in resolvers map.`
)
}
}
}
}
}
}
