### Import and usage of DOMException

Source: https://github.com/jimmywarting/node-domexception/blob/main/README.md

Examples of importing the package and verifying DOMException behavior.

```javascript
import 'node-domexception'

// You could also do conditional import.
globalThis.DOMException || await import('node-domexception')

/********************************************************************/

import { MessageChannel } from 'worker_threads'

try {
  const port = new MessageChannel().port1
  const ab = new ArrayBuffer()
  port.postMessage(ab, [ab, ab])
} catch (err) {
  console.assert(err.name === 'DataCloneError')
  console.assert(err.code === 25)
  console.assert(err.constructor === DOMException)
}

const e1 = new DOMException('Something went wrong', 'BadThingsError')
console.assert(e1.name === 'BadThingsError')
console.assert(e1.code === 0)

const e2 = new DOMException('Another exciting error message', 'NoModificationAllowedError')
console.assert(e2.name === 'NoModificationAllowedError')
console.assert(e2.code === 7)

console.assert(DOMException.INUSE_ATTRIBUTE_ERR === 10)
```

--------------------------------

### Import Node DOMException Polyfill

Source: https://context7.com/jimmywarting/node-domexception/llms.txt

Import this module to add DOMException to the global scope. Use the conditional import to avoid loading if DOMException is already available.

```javascript
import 'node-domexception'

// Conditional import - only load if DOMException is not already available
globalThis.DOMException || await import('node-domexception')
```

--------------------------------

### Create Custom DOMException Instances

Source: https://context7.com/jimmywarting/node-domexception/llms.txt

Instantiate DOMException with a message and an optional name. Custom names map to a default code of 0, while predefined names are assigned specific legacy codes.

```javascript
import 'node-domexception'

// Create a custom DOMException with a custom name (code defaults to 0)
const customError = new DOMException('Something went wrong', 'BadThingsError')
console.log(customError.name)    // 'BadThingsError'
console.log(customError.message) // 'Something went wrong'
console.log(customError.code)    // 0

// Create a DOMException with a predefined name (gets automatic code)
const noModError = new DOMException('Cannot modify', 'NoModificationAllowedError')
console.log(noModError.name)     // 'NoModificationAllowedError'
console.log(noModError.code)     // 7
```

--------------------------------

### Catch and Identify DOMException Errors

Source: https://context7.com/jimmywarting/node-domexception/llms.txt

Use 'instanceof DOMException' to reliably identify errors originating from Node.js APIs that conform to the DOMException standard.

```javascript
import 'node-domexception'
import { MessageChannel } from 'worker_threads'

try {
  const port = new MessageChannel().port1
  const ab = new ArrayBuffer()
  // Attempting to transfer the same buffer twice throws DataCloneError
  port.postMessage(ab, [ab, ab])
} catch (err) {
  if (err instanceof DOMException) {
    console.log(err.name)        // 'DataCloneError'
    console.log(err.code)        // 25
    console.log(err.message)     // Error message from Node.js
  }
}
```

--------------------------------

### Update package.json engines

Source: https://github.com/jimmywarting/node-domexception/blob/main/README.md

Configure the engines field to require Node.js 18 or higher.

```json
{
  "engine": {
    "node": ">=18"
  }
}
```

--------------------------------

### Access Legacy DOMException Error Codes

Source: https://context7.com/jimmywarting/node-domexception/llms.txt

Access static properties on the DOMException class to retrieve the numerical codes associated with standard Web IDL error names.

```javascript
import 'node-domexception'

// Access predefined error code constants
console.log(DOMException.INDEX_SIZE_ERR)              // 1
console.log(DOMException.DOMSTRING_SIZE_ERR)          // 2
console.log(DOMException.HIERARCHY_REQUEST_ERR)       // 3
console.log(DOMException.WRONG_DOCUMENT_ERR)          // 4
console.log(DOMException.INVALID_CHARACTER_ERR)       // 5
console.log(DOMException.NO_DATA_ALLOWED_ERR)         // 6
console.log(DOMException.NO_MODIFICATION_ALLOWED_ERR) // 7
console.log(DOMException.NOT_FOUND_ERR)               // 8
console.log(DOMException.NOT_SUPPORTED_ERR)           // 9
console.log(DOMException.INUSE_ATTRIBUTE_ERR)         // 10
console.log(DOMException.INVALID_STATE_ERR)           // 11
console.log(DOMException.SYNTAX_ERR)                  // 12
console.log(DOMException.INVALID_MODIFICATION_ERR)    // 13
console.log(DOMException.NAMESPACE_ERR)               // 14
console.log(DOMException.INVALID_ACCESS_ERR)          // 15
console.log(DOMException.TYPE_MISMATCH_ERR)           // 17
console.log(DOMException.SECURITY_ERR)                // 18
console.log(DOMException.NETWORK_ERR)                 // 19
console.log(DOMException.ABORT_ERR)                   // 20
console.log(DOMException.URL_MISMATCH_ERR)            // 21
console.log(DOMException.QUOTA_EXCEEDED_ERR)          // 22
console.log(DOMException.TIMEOUT_ERR)                 // 23
console.log(DOMException.INVALID_NODE_TYPE_ERR)       // 24
console.log(DOMException.DATA_CLONE_ERR)              // 25
```
