# Error handling
|
|
|
|
Error handling can be done via promises like this:
|
|
|
|
```javascript
|
|
// fetching the heic image
|
|
fetch("./my-image.heic")
|
|
.then((res) => res.blob())
|
|
.then((blob) => heic2any({ blob }))
|
|
.then((conversionResult) => {
|
|
var url = URL.createObjectURL(conversionResult);
|
|
document.getElementById("my-image").innerHTML = `<img src="${url}">`;
|
|
})
|
|
.catch((errorObject) => {
|
|
console.log(errorObject);
|
|
});
|
|
```
|
|
|
|
When an error occurs the `console.log` of the above example would output for example:
|
|
|
|
```json
|
|
{
|
|
"code": 1,
|
|
"message": "ERR_USER library only accepts BLOBs as input"
|
|
}
|
|
```
|
|
|
|
The `code` property represents a class of error, while the `message` property explains deeper details of why the error occurred.
|
|
|
|
