Model Aggregation

Loopback4 supports model aggregations using inclusion resolvers, you can pass your include params per model:

// in src/App.tsx
import { Admin, Resource } from "react-admin";
import lb4Provider from "ra-data-lb4";

const aggregate = (resource: string) => {
    if (resource === "posts") {
        return [
            {
                relation: "author",
            },
        ];
    }

    return [];
};

const provider = lb4Provider("http://path.to.my.api/", aggregate);

// in src/App.tsx
import { fetchUtils, Admin, Resource } from "react-admin";
import lb4Provider from "ra-data-lb4";

const httpClient = (url, options = {}) => {
    if (!options.headers) {
        options.headers = new Headers({ Accept: "application/json" });
    }
    // add your own headers here
    options.headers.set("X-Custom-Header", "foobar");
    return fetchUtils.fetchJson(url, options);
