Use Cases

Constrained environments where you need reliability without complexity:

• No external dependencies
• Vanilla JavaScript (ES6+)

Enterprise patterns included:

• Circuit breakers prevent cascade failures
• ETags reduce bandwidth usage
• Request deduplication improves performance
• Auth-aware caching prevents security issues

Configuration

const api = new Grab({
    baseUrl: 'https://api.example.com',
    timeout: 30000,
    headers: { 'Authorization': 'Bearer token' },
cache: {
    enabled: true,
    ttl: 5 * 60 * 1000,  // 5 minutes
    maxSize: 100
},

retry: {
    attempts: 3,
    delay: (attempt) => Math.min(1000 * Math.pow(2, attempt - 1), 30000),
    condition: (error) => error.status >= 500
},

circuitBreaker: {
    failureThreshold: 5,
    resetTimeout: 60000
}

});
// Add interceptors

api.use({

request: (config) => {

config.headers.Timestamp = Date.now();

return config;

},

error: (error) => {

if (error.status === 401) {

window.location.href = '/login';

}

throw error;

}

});
