I am getting a response from an Api that looks like this:
property: Array(100)
0: {identifier: {…}, address: {…}, location: {…}, vintage: {…}}
1: {identifier: {…}, address: {…}, location: {…}, vintage: {…}}
2: {identifier: {…}, address: {…}, location: {…}, vintage: {…}}
3: {identifier: {…}, address: {…}, location: {…}, vintage: {…}}
I am wanting a list of some specified fields in the address object for instance just country and oneLine, but for every index of the property
array
address:
country: "US"
countrySubd: "CA"
line1: "1702 ELKHORN RD"
line2: "ROYAL OAKS, CA 95076"
locality: "Royal Oaks"
matchCode: "ExaStr"
oneLine: "1702 ELKHORN RD, ROYAL OAKS, CA 95076"
postal1: "95076"
postal2: "9218"
postal3: "R002"
I have been struggling for 2 days on how to write the schema for this in my graphql schema page. Can somebody please help me?
here is what I have been trying but keep getting null value for data
require("es6-promise").polyfill();
require("isomorphic-fetch");
const {
GraphQLString,
GraphQLList,
GraphQLSchema,
GraphQLObjectType,
GraphQLInt
} = require("graphql");
const Identifier = new GraphQLObjectType({
name: "identifier",
fields: () => ({
obPropId: { type: GraphQLInt }
})
});
const AddressType = new GraphQLObjectType({
name: 'Address',
fields: () => ({
country: { type: GraphQLString },
oneLine: {type: GraphQLString }
})
})
const RootQuery = new GraphQLObjectType({
name: "RootQueryType",
fields: {
property: {
type: new GraphQLList(Identifier),
resolve(parent, args) {
return fetch(
"https://api.gateway.attomdata.com/propertyapi/v1.0.0/property/address?postalcode=95076&page=1&pagesize=100",
{
headers: {
Accept: "application/json",
APIKey: "XXXXXXXXXXXXXXXXXXXX"
}
}
)
.then((response) => {
const jsonResponse = response.json();
return jsonResponse
}).then((jsonResonse) => console.log(JSON.stringify(jsonResonse)))
.then(res => res.data)
.catch(error => {
console.log(error);
});
}
}
}
});
module.exports = new GraphQLSchema({
query: RootQuery
});
Im running it on a express server and do my checks on localhost:5000/graphql
In the comments we were able to work out the following:
Another type is required to connect the Address type with the RootQuery type. We can introduce the type and adjust the return type of the query type:
type Property {
id: Identifier
address: Address
}
type Query {
property: [Property] # consider using plural field name "properties"
}
I created a working Codesandboy to show how it behaves.
