This plugin helps you to forbid DOM globals within the react server side rendering.
- it doesn't support yet React classes
- it supports react hooks and custom hooks
- it requires some naming conventions to identify other functions where globals may be allowed
You'll first need to install ESLint:
$ npm i eslint --save-dev
Next, install eslint-plugin-react-hooks-ssr
:
$ npm install eslint-plugin-react-hooks-ssr --save-dev
Note: If you installed ESLint globally (using the -g
flag) then you must also install eslint-plugin-react-hooks-ssr
globally.
Add react-hooks-ssr
to the plugins section of your .eslintrc.js
configuration file. You can omit the eslint-plugin-
prefix:
{
"plugins": [
"react-hooks-ssr"
]
}
Optionally configure the regexp to whitelist globals within certain function declarations (by default the async
prefix).
{
"rules": {
"react-hooks-ssr/react-hooks-global-ssr": ["error", { "allowFuncRegExp": /test/ }]
}
}
- a global within
useEffect
is allowed
function Component() {
useEffect(() => {
console.log(window.innerWidth);
});
return <div>Hello</div>;
}
- a global within a custom hook (
useXXX
) is allowed
function Component() {
useCustomHook(() => {
console.log(window.innerWidth);
});
return <div>Hello</div>;
}
- a global within a function prefixed by
async
(asyncMyFunc
) is allowed. This pattern can be replaced by theallowFuncRegExp
option
function asyncMyFunction() {
console.log(window.innerWidth);
}
- a global within a
useState
,useReducer
anduseMemo
callback is forbidden
function Component() {
const [myState, setMyState] = useState(() => {
return window.innerWidth
});
return <div>Hello</div>;
}
- a global within a React
Component
is forbidden
function Component() {
console.log(window.innerWidth)
return <div>Hello</div>;
}
