> 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: 🦄]
|
||
|
```
|
||
|
|
||
|
## API
|
||
|
|
||
|
### serializeError(value)
|
||
|
|
||
|
Type: `Error | unknown`
|
||
|
|
||
|
Serialize an `Error` object into a plain object.
|
||
|
|
||
|
Non-error values are passed through.
|
||
|
Custom properties are preserved.
|
||
|
Non-enumerable properties are kept non-enumerable (name, message, stack).
|
||
|
Enumerable properties are kept enumerable (all properties besides the non-enumerable ones).
|
||
|
Circular references are handled.
|
||
|
|
||
|
### deserializeError(value)
|
||
|
|
||
|
Type: `{[key: string]: unknown} | unknown`
|
||
|
|
||
|
Deserialize a plain object or any value into an `Error` object.
|
||
|
|
||
|
`Error` objects are passed through.
|
||
|
Non-error values are wrapped in a `NonError` error.
|
||
|
Custom properties are preserved.
|
||
|
Circular references are handled.
