GraphQL Hapi Plugin
Create a GraphQL HTTP server with Hapi. Port from express-graphql.
npm install --save hapi-graphql
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: {
# options, see below
},
// OR
//
// query: (request) => ({
// # options, see below
// }),
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 from [graphql-js
][]. Aschema
must be provided. -
context
: A value to pass as thecontext
to thegraphql()
function from [graphql-js
][]. -
rootValue
: A value to pass as therootValue
to thegraphql()
function from [graphql-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-compliant [formatError
][] 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
})
