A simple POST request using the fetch API

fetch-api-post.js

fetch(url, {  
    method: 'POST',  
    headers: {  
      'auth': '1234'  
    },  
     body: JSON.stringify({
    name: 'dean',
    login: 'dean',
  })
})
.then(function (data) {  
  console.log('Request success: ', data);  
})  
.catch(function (error) {  
  console.log('Request failure: ', error);  
});

You need to enable CORS on your server-side application. Please check it

@rakaar where can I find the CORS Documentation?

some useful links

• https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS

many frameworks like flask, node js have middleware packages which can be used directly

Thank You great and simple explanation.
