How do I make a POST call in React Native?

css’; function callApi() { alert(‘Button was pressed! ‘); } function App() { return ( <div className=”App”> <header className=”App-header”> <button onClick={callApi}>Call API</button> </header> </div> ); } export default App; This will give us a button that when pressed will show an alert saying Button was pressed! .

We’ll cover the following options for fetching data in React Native:

First, we specify the ‘method’, POST. Then, we specify the value of ‘mode’. Since the Flask server is being hosted on a different port on our machine (8080) than the React app, we have to specify the value as ‘cors’. All this means is that data will be sent across origins.

In React Native, you can request data from an API over the network using the fetch() method. The syntax is simple as follows: fetch(‘https://examples.com/data.json’); We simply pass the URL to the fetch method to make a request.23 Kas 2020
