Readme
This is the example React code that goes through wyw-in-js
preeval stage:
const Divider = /*#__PURE__*/ _s(
React.forwardRef(
(_c = _s(
function Divider(inProps, ref) {
_s();
// ...
return /*#__PURE__*/ _jsx(
DividerRoot,
_extends(
{
as: component,
className: clsx(classes.root, className),
role: role,
ref: ref,
ownerState: ownerState,
},
other,
{
children: children
? /*#__PURE__*/ _jsx(DividerWrapper, {
className: classes.wrapper,
ownerState: ownerState,
children: children,
})
: null,
}
)
);
},
'526RDEpO1CGEADq5vnCvoNyCejQ=',
false,
function() {
return [useThemeProps, useUtilityClasses];
}
))
),
'526RDEpO1CGEADq5vnCvoNyCejQ=',
false,
function() {
return [useThemeProps, useUtilityClasses];
}
);
_c1 = Divider;
/**
* The following flag is used to ensure that this component isn't tabbable i.e.
* does not get highlight/focus inside of MUI List.
*/ Divider.muiSkipListHighlight = true;
export default Divider;
var _c, _c1;
$RefreshReg$(_c, 'Divider$React.forwardRef');
$RefreshReg$(_c1, 'Divider');
The $RefreshReg$
is injected by React Refresh from a framework like Next.js or Vite. In the preeval phase, wyw-in-js
will remove the global $RefreshReg$
but there is a bug in removing the _c
(I am not sure is it the bug in wyw-in-js
or babel
) so the code that go through evaluation looks like this:
const Divider = /*#__PURE__*/ _s(
React.forwardRef(
(_c = _s(
function Divider(inProps, ref) {
_s();
// ...
},
'526RDEpO1CGEADq5vnCvoNyCejQ=',
false,
function() {
return [useThemeProps, useUtilityClasses];
}
))
),
'526RDEpO1CGEADq5vnCvoNyCejQ=',
false,
function() {
return [useThemeProps, useUtilityClasses];
}
);
/**
* The following flag is used to ensure that this component isn't tabbable i.e.
* does not get highlight/focus inside of MUI List.
*/ Divider.muiSkipListHighlight = true;
export default Divider;
Causing the error _c is not defined
.
This plugin will replace the _c = _s(...)
with _s(...)
directly so that there is no use of the variable to make the evalution works.
