# $ yarn add aspida @aspida/swr @aspida/fetch swr
# $ yarn add aspida @aspida/swr @aspida/node-fetch swr node-fetch

Make HTTP request from application

src/index.ts

import aspida from "@aspida/axios"; // "@aspida/fetch", "@aspida/node-fetch"
import useAspidaSWR from "@aspida/swr";
import api from "../api/$api";

const client = api(aspida());

function Profile() {
  const { data, error } = useAspidaSWR(client.user._userId(123), { query: { name: "mario" } });

  if (error) return <div>failed to load</div>;
  if (!data) return <div>loading...</div>;
  return <div>hello {data.name}!</div>;
}

Get response body/status/headers

src/index.ts

import aspida from "@aspida/axios"; // "@aspida/fetch", "@aspida/node-fetch"
import useAspidaSWR from "@aspida/swr";
import api from "../api/$api";

const client = api(aspida());

function Profile() {
  const { data, error } = useAspidaSWR(client.user._userId(123), "get", {
    query: { name: "mario" },
  });

  if (error) return <div>failed to load</div>;
  if (!data) return <div>loading...</div>;
  return (
    <>
      <div>Status: {data.status}</div>
      <div>Headers: {JSON.stringify(data.headers)}</div>
      <div>Name: {data.body.name}</div>
    </>
  );
}

useAspidaSWR(client.user._userId(123), { query }) is an alias of useAspidaSWR(client.user._userId(123), "$get", { query })

Use with SWR options

src/index.ts

import aspida from "@aspida/axios"; // "@aspida/fetch", "@aspida/node-fetch"
import useAspidaSWR from "@aspida/swr";
import api from "../api/$api";

const client = api(aspida());

function Profile() {
  const { data, error } = useAspidaSWR(client.user._userId(123), {
    query: { name: "mario" },
    revalidateOnMount: true,
    initialData: { name: "anonymous" },
  });

  if (error) return <div>failed to load</div>;
  return <div>hello {data.name}!</div>;
}

Conditional Fetching

If you use the enabled = false option, AspidaSWR will not start the request.

const { data: user } = useAspidaSWR(client.user);
const { data } = useAspidaSWR(client.articles, {
  query: { userId: user?.id ?? 0 },
  enabled: !!user,
});
// is an alias of
const { data } = useSWR(
  user ? [client.articles.$path({ query: { userId: user.id } }), "$get"] : null,
  () => client.articles.$get({ query: { userId: user.id } })
);
