hapi-graphql-updated v0.5.7
GraphQL Hapi Plugin
This is a fork of hapi-graphql which addresses some problems and uses an updated version of GraphQL.
Create a GraphQL HTTP server with Hapi. Port from express-graphql.
npm install --save hapi-graphql-updated
Example
import Hapi from 'hapi';
import GraphQL from 'hapi-graphql';
import {GraphQLSchema} from 'graphql';
const server = new Hapi.Server();
server.connection({
port: 3000
});
const TestSchema = new GraphQLSchema({});
server.register({
register: GraphQL,
options: {
query: {
schema: TestSchema,
rootValue: {},
pretty: false
},
// OR
//
// query: (request) => ({
// schema: TestSchema,
// rootValue: {},
// graphiql: true,
// })
route: {
path: '/graphql',
config: {}
}
}
}, () =>
server.start(() =>
console.log('Server running at:', server.info.uri)
)
);
Options
The options
key of query
accepts the following:
schema
: AGraphQLSchema
instance fromgraphql-js
. Aschema
must be provided.context
: A value to pass as thecontext
to thegraphql()
function fromgraphql-js
.rootValue
: A value to pass as therootValue
to thegraphql()
function fromgraphql-js
.pretty
: Iftrue
, any JSON response will be pretty-printed.formatError
: An optional function which will be used to format any errors produced by fulfilling a GraphQL operation. If no function is provided, GraphQL's default spec-compliantformatError
function will be used.validationRules
: Optional additional validation rules queries must satisfy in addition to those defined by the GraphQL spec.graphiql
: Iftrue
, may present GraphiQL when loaded directly from a browser (a useful tool for debugging and exploration).
Debugging
During development, it's useful to get more information from errors, such as
stack traces. Providing a function to formatError
enables this:
formatError: error => ({
message: error.message,
locations: error.locations,
stack: error.stack
})
