Add coexistence checks to all enqueue methods to prevent loading both React and Grid.js assets simultaneously. Changes: - ReactAdmin.php: Only enqueue React assets when ?react=1 - Init.php: Skip Grid.js when React active on admin pages - Form.php, Coupon.php, Access.php: Restore classic assets when ?react=0 - Customer.php, Product.php, License.php: Add coexistence checks Now the toggle between Classic and React versions works correctly.

=========
|
|
|
|
A library to make errors.
|
|
|
|
|
|
Basics
|
|
------
|
|
|
|
Makes an Error constructor function with the signature below. All arguments are
|
|
optional, and if the first argument is not a `String`, it will be assumed to be
|
|
`data`:
|
|
|
|
```javascript
|
|
function(message, data)
|
|
```
|
|
|
|
You'll typically do something like:
|
|
|
|
```javascript
|
|
var makeError = require('makeerror')
|
|
var UnknownFileTypeError = makeError(
|
|
'UnknownFileTypeError',
|
|
'The specified type is not known.'
|
|
)
|
|
var er = UnknownFileTypeError()
|
|
```
|
|
|
|
`er` will have a prototype chain that ensures:
|
|
|
|
```javascript
|
|
er instanceof UnknownFileTypeError
|
|
er instanceof Error
|
|
```
|
|
|
|
|
|
Templatized Error Messages
|
|
--------------------------
|
|
|
|
There is support for simple string substitutions like:
|
|
|
|
```javascript
|
|
var makeError = require('makeerror')
|
|
var UnknownFileTypeError = makeError(
|
|
'UnknownFileTypeError',
|
|
'The specified type "{type}" is not known.'
|
|
)
|
|
var er = UnknownFileTypeError({ type: 'bmp' })
|
|
```
|
|
|
|
Now `er.message` or `er.toString()` will return `'The specified type "bmp" is
|
|
not known.'`.
|
|
|
|
|
|
Prototype Hierarchies
|
|
---------------------
|
|
|
|
You can create simple hierarchies as well using the `prototype` chain:
|
|
|
|
```javascript
|
|
var makeError = require('makeerror')
|
|
var ParentError = makeError('ParentError')
|
|
var ChildError = makeError(
|
|
'ChildError',
|
|
'The child error.',
|
|
{ proto: ParentError() }
|
|
)
|
|
var er = ChildError()
|
|
```
|
|
|
|
`er` will have a prototype chain that ensures:
|
|
|
|
```javascript
|
|
er instanceof ChildError
|
|
er instanceof ParentError
|
|
er instanceof Error
|
|
```
