This means that whenever an asynchronous call is required, the library method will return a native Javascript promise. You can therefore choose between using `promise` or `async/await` syntax when calling our async methods. + +_Async/await syntax (recommended):_ + +```javascript +try { + const signature = await signatureUtils.ecSignOrderHashAsync( + providerEngine, + orderHashHex, + maker, + SignerType.Default, + ); +} catch (error) { + console.log('Caught error: ', error); +} +``` + +_Promise syntax:_ + +```javascript +signatureUtils + .ecSignOrderHashAsync(providerEngine, orderHashHex, maker, SignerType.Default) + .then(function(signature) { + console.log(signature); + }) + .catch(function(error) { + console.log('Caught error: ', error); + }); +``` + +As is the convention with promise-based libraries, if an error occurs, it is thrown. It is the callers responsibility to catch thrown errors and to handle them appropriately. |
