> Serialize/deserialize an error into a plain object
|
||
|
|
||
|
Useful if you for example need to `JSON.stringify()` or `process.send()` the error.
|
||
|
|
||
|
|
||
|
## Install
|
||
|
|
||
|
```
|
||
|
$ npm install serialize-error
|
||
|
```
|
||
|
|
||
|
|
||
|
## Usage
|
||
|
|
||
|
```js
|
||
|
const {serializeError, deserializeError} = require('serialize-error');
|
||
|
|
||
|
const error = new Error('🦄');
|
||
|
|
||
|
console.log(error);
|
||
|
//=> [Error: 🦄]
|
||
|
|
||
|
const serialized = serializeError(error)
|
||
|
|
||
|
console.log(serialized);
|
||
|
//=> {name: 'Error', message: '🦄', stack: 'Error: 🦄\n at Object.<anonymous> …'}
|
||
|
|
||
|
const deserialized = deserializeError(serialized);
|
||
|
//=> [Error: 🦄]
|
||
|
```

|
||
|
|

|
Type: `{[key: string]: unknown} | unknown`
|
||

|
Deserialize a plain object or any value into an `Error` object.
