Simple graphQL query gives error - angularjs

Question

I am trying to use graphql for one of the GET request based on an id. Here's the code:
const { graphql, buildSchema } = require('graphql');
EmployeeService.prototype.getEmployee = function() {
// Construct a schema
const schema = buildSchema(`
type Query {
employee(id="12345") {
id
items {
id
name
}
}
}
`);
// The root provides a resolver function
let root = {
employee: () => id
};
// Run the GraphQL query
graphql(schema, '{ employee }', root).then((response) => {
console.log(response);
});
};
Trying to follow the documentation on http://graphql.org/graphql-js/.
I get a GraphQL error: "Syntax Error GraphQL request (3:19) Expected :, found =↵↵2: type Query {↵3: employee (id="12345") {↵ ^↵4: id↵"
Please advise.

You are maybe mixing things a little bit up. The schema and resolvers are part of your API and are not needed to make a query on a client. Just for demonstration purposes here a valid schema definition (that would normally run on a API server):
let schema = buildSchema(`
type Item {
id: Int!
name: String!
}
type Employee {
id: Int!
items: [Item]
}
type Query {
employee(id: Int!): Employee
}
`);
You then define your types and resolvers (simplified examples):
class Employee {
constructor(id, items) {
this.id = id;
this.items = items;
}
}
let root = {
employee: ({id}) => {
return new Employee(id, [{id: 1, name: 'Item 1'}, {id: 2, name: 'Item2'}]);
}
};
You can then run a query:
const query = `
{
employee(id: 1) {
id,
items {
id,
name
}
}
}
`;
graphql(schema, query, root).then((response) => {
console.log(response.data);
});
To run actual queries against a remote API have a look at GraphQL clients like Apollo or lokka
