Expo Networking

You MUST use this skill for ANY networking work including API requests, data fetching, caching, or network debugging.

References

Consult these resources as needed:

references/
  expo-router-loaders.md        Route-level data loading with Expo Router loaders (web, SDK 55+)
  offline-and-cancellation.md   NetInfo network status, offline-first React Query, AbortController

When to Use

Use this skill when:

  • Implementing API requests
  • Setting up data fetching (React Query, SWR)
  • Using Expo Router data loaders (useLoaderData, web SDK 55+)
  • Debugging network failures
  • Implementing caching strategies
  • Handling offline scenarios
  • Authentication/token management
  • Configuring API URLs and environment variables

Preferences

  • Avoid axios, prefer expo/fetch

Common Issues & Solutions

1. Basic Fetch Usage

Simple GET request:

const fetchUser = async (userId: string) => {
  const response = await fetch(`https://api.example.com/users/${userId}`);

  if (!response.ok) {
    throw new Error(`HTTP error! status: ${response.status}`);
  }

  return response.json();
};

POST request with body:

const createUser = async (userData: UserData) => {
  const response = await fetch("https://api.example.com/users", {
    method: "POST",
    headers: {
      "Content-Type": "application/json",
      Authorization: `Bearer ${token}`,
    },
    body: JSON.stringify(userData),
  });

  if (!response.ok) {
    const error = await response.json();
    throw new Error(error.message);
  }

  return response.json();
};
2. React Query (TanStack Query)

Setup:

// app/_layout.tsx
import { QueryClient, QueryClientProvider } from "@tanstack/react-query";

const queryClient = new QueryClient({
  defaultOptions: {
    queries: {
      staleTime: 1000 * 60 * 5, // 5 minutes
      retry: 2,
    },
  },
});

export default function RootLayout() {
  return (
    <QueryClientProvider client={queryClient}>
      <Stack />
    </QueryClientProvider>
  );
}

Fetching data:

import { useQuery } from "@tanstack/react-query";

function UserProfile({ userId }: { userId: string }) {
  const { data, isLoading, error, refetch } = useQuery({
    queryKey: ["user", userId],
    queryFn: () => fetchUser(userId),
  });

  if (isLoading) return <Loading />;
  if (error) return <Error message={error.message} />;

  return <Profile user={data} />;
}

Mutations:

import { useMutation, useQueryClient } from "@tanstack/react-query";

function CreateUserForm() {
  const queryClient = useQueryClient();

  const mutation = useMutation({
    mutationFn: createUser,
    onSuccess: () => {
      // Invalidate and refetch
      queryClient.invalidateQueries({ queryKey: ["users"] });
    },
  });

  const handleSubmit = (data: UserData) => {
    mutation.mutate(data);
  };

  return <Form onSubmit={handleSubmit} isLoading={mutation.isPending} />;
}
3. Error Handling

Comprehensive error handling:

class ApiError extends Error {
  constructor(message: string, public status: number, public code?: string) {
    super(message);
    this.name = "ApiError";
  }
}

const fetchWithErrorHandling = async (url: string, options?: RequestInit) => {
  try {
    const response = await fetch(url, options);

    if (!response.ok) {
      const error = await response.json().catch(() => ({}));
      throw new ApiError(
        error.message || "Request failed",
        response.status,
        error.code
      );
    }

    return response.json();
  } catch (error) {
    if (error instanceof ApiError) {
      throw error;
    }
    // Network error (no internet, timeout, etc.)
    throw new ApiError("Network error", 0, "NETWORK_ERROR");
  }
};

Retry logic:

const fetchWithRetry = async (
  url: string,
  options?: RequestInit,
  retries = 3
) => {
  for (let i = 0; i < retries; i++) {
    try {
      return await fetchWithErrorHandling(url, options);
    } catch (error) {
      if (i === retries - 1) throw error;
      // Exponential backoff
      await new Promise((r) => setTimeout(r, Math.pow(2, i) * 1000));
    }
  }
};
4. Authentication

Token management:

import * as SecureStore from "expo-secure-store";

const TOKEN_KEY = "auth_token";

export const auth = {
  getToken: () => SecureStore.getItemAsync(TOKEN_KEY),
  setToken: (token: string) => SecureStore.setItemAsync(TOKEN_KEY, token),
  removeToken: () => SecureStore.deleteItemAsync(TOKEN_KEY),
};

// Authenticated fetch wrapper
const authFetch = async (url: string, options: RequestInit = {}) => {
  const token = await auth.getToken();

  return fetch(url, {
    ...options,
    headers: {
      ...options.headers,
      Authorization: token ? `Bearer ${token}` : "",
    },
  });
};

Token refresh:

let isRefreshing = false;
let refreshPromise: Promise<string> | null = null;

const getValidToken = async (): Promise<string> => {
  const token = await auth.getToken();

  if (!token || isTokenExpired(token)) {
    if (!isRefreshing) {
      isRefreshing = true;
      refreshPromise = refreshToken().finally(() => {
        isRefreshing = false;
        refreshPromise = null;
      });
    }
    return refreshPromise!;
  }

  return token;
};
5. Offline Support

Network-status detection with NetInfo and offline-first React Query setup: see ./references/offline-and-cancellation.md.

6. Environment Variables

Using environment variables for API configuration:

Expo supports environment variables with the EXPO_PUBLIC_ prefix. These are inlined at build time and available in your JavaScript code.

// .env
EXPO_PUBLIC_API_URL=https://api.example.com
EXPO_PUBLIC_API_VERSION=v1

// Usage in code
const API_URL = process.env.EXPO_PUBLIC_API_URL;

const fetchUsers = async () => {
  const response = await fetch(`${API_URL}/users`);
  return response.json();
};

Environment-specific configuration:

// .env.development
EXPO_PUBLIC_API_URL=http://localhost:3000

// .env.production
EXPO_PUBLIC_API_URL=https://api.production.com

Creating an API client with environment config:

// api/client.ts
const BASE_URL = process.env.EXPO_PUBLIC_API_URL;

if (!BASE_URL) {
  throw new Error("EXPO_PUBLIC_API_URL is not defined");
}

export const apiClient = {
  get: async <T,>(path: string): Promise<T> => {
    const response = await fetch(`${BASE_URL}${path}`);
    if (!response.ok) throw new Error(`HTTP ${response.status}`);
    return response.json();
  },

  post: async <T,>(path: string, body: unknown): Promise<T> => {
    const response = await fetch(`${BASE_URL}${path}`, {
      method: "POST",
      headers: { "Content-Type": "application/json" },
      body: JSON.stringify(body),
    });
    if (!response.ok) throw new Error(`HTTP ${response.status}`);
    return response.json();
  },
};

Important notes:

  • Only variables prefixed with EXPO_PUBLIC_ are exposed to the client bundle
  • Never put secrets (API keys with write access, database passwords) in EXPO_PUBLIC_ variables—they're visible in the built app
  • Environment variables are inlined at build time, not runtime
  • Restart the dev server after changing .env files
  • For server-side secrets in API routes, use variables without the EXPO_PUBLIC_ prefix

TypeScript support:

// types/env.d.ts
declare global {
  namespace NodeJS {
    interface ProcessEnv {
      EXPO_PUBLIC_API_URL: string;
      EXPO_PUBLIC_API_VERSION?: string;
    }
  }
}

export {};
7. Request Cancellation

AbortController on unmount (React Query cancels automatically): see ./references/offline-and-cancellation.md.

Common Mistakes

Wrong: No error handling

const data = await fetch(url).then((r) => r.json());

Right: Check response status

const response = await fetch(url);
if (!response.ok) throw new Error(`HTTP ${response.status}`);
const data = await response.json();

Wrong: Storing tokens in AsyncStorage

await AsyncStorage.setItem("token", token); // Not secure!

Right: Use SecureStore for sensitive data

await SecureStore.setItemAsync("token", token);

Example Invocations

User: "How do I make API calls in React Native?" -> Use fetch, wrap with error handling

User: "Should I use React Query or SWR?" -> React Query for complex apps, SWR for simpler needs

User: "My app needs to work offline" -> Use NetInfo for status, React Query persistence for caching

User: "How do I handle authentication tokens?" -> Store in expo-secure-store, implement refresh flow

User: "API calls are slow" -> Check caching strategy, use React Query staleTime User: "How do I configure different API URLs for dev and prod?" -> Use EXPO_PUBLIC_ env vars with .env.development and .env.production files User: "Where should I put my API key?" -> Client-safe keys: EXPO_PUBLIC_ in .env. Secret keys: non-prefixed env vars in API routes only

User: "How do I load data for a page in Expo Router?" -> See references/expo-router-loaders.md for route-level loaders (web, SDK 55+). For native, use React Query or fetch.

  • Dependency or permission surface needs review
  • Permission surface may require sandboxing
  • Financial research output is not financial advice; require human review before any live investment decision
  • SKILL.md promises coverage of SWR in the description, but the provided skill content does not include any SWR-specific examples or guidance.
  • The skill is reference-heavy and lacks an explicit step-by-step workflow or decision framework for choosing between fetch, React Query, SWR, and Expo Router loaders.
  • Security best practices are only implicit; the skill could more clearly warn against logging tokens, leaking auth headers, or fetching untrusted URLs.
  • Some sections appear truncated in the submitted excerpt (e.g., the authFetch example cuts off), which may reduce clarity if the full SKILL.md is not complete.
  • Financial research output is not financial advice; require human review before any live investment decision.
  • Quality score needs review
  • Permission surface needs review: secrets or environment access, shell or command execution
  • Dependency/runtime risk: command execution surface, credential or environment access
  • Permission surface: secrets or environment access, shell or command execution
