Error handling
There are different errors that could happen while using the WebLN APIs:
  • User denies access to WebLN
  • User cancels the process
  • Connection errors
  • Payment errors
When an error happens during a WebLN API call the exception is thrown. Thus it is heavily recommended to handle different kinds of errors and let the user know what went wrong.
function pay() {
if(typeof window.webln === 'undefined')
return;
try {
await window.webln.enable();
await window.webln.sendPayment(...);
}
catch(err) {
console.log(error);
}
}
