Helper functions that allow you to build normalizr schemas from graphql schemas.
A minimum TypeScript app with Parcel Bundler.
For more details, see src/.
To play around StackBlitz.
import { normalize } from "normalizr";
import { buildNormalizrSchemas, generateRelationsString } from "./lib";
const graphqlSchema = `
type User {
id: String
name: String
parents: [User]
}
type Home {
guid: String
address: String
tenants: [User]
}
`;
const relationsGraphString = generateRelationsString(graphqlSchema);
const schemas = buildNormalizrSchemas<'User'|'Home'>(relationsGraphString, {
User: 'id',
Home: 'guid'
});
const home = {
guid: 'home1',
address: 'Home Address',
tenants: [
{ id: 'user1', name: 'User 1', parents: [
{ id: 'user2', name: 'User 2' },
{ id: 'user4', name: 'User 4' }
] },
{ id: 'user3', name: 'User 3', parents: [
{ id: 'user2', name: 'User 2' },
{ id: 'user5' }
] },
]
}
const normalized = normalize(home, schemas.Home);The output will be:
{
entities: {
Home: {
'home1': { guid: 'home1', address: 'Home Address', tenants: ['user1', 'user3']}
},
User: {
'user1': { id: 'user1', name: 'User 1', parents: ['user2', 'user4'] }
'user2': { id: 'user2', name: 'User 2', }
'user3': { id: 'user3', name: 'User 3', parents: ['user2', 'user5'] }
'user4': { id: 'user4', name: 'User 4' }
'user5': { id: 'user5', }
}
}
