I have a simple page editor, When a user clicks edit page it opens an editor. I am passing the ID of the page using redux which will be used to get data from API.
Here is my Editor.
const [pageData, setPageData] = useState("");
const getPage = async (id) => {
try {
const response = await api.get(`/landing_pages/${id}`);
console.log("page", response.data); // displays data at the end
setPageData(response.data);
} catch (error) {
console.log(error);
}
};
useEffect(() => {
getPage(pageID);
console.log('Page Data', pageData) // displays nothing
let LandingPage = pageData;
const editor = grapesjs.init({
container: "#editor",
components: LandingPage.components || LandingPage.html,
})
}, [pageID, getPage])
Why is Page Data display nothing even though the data from API is returned and is displayed in the console at the end? what am I doing wrong here?
Even if you await
your getPage
call, the updated pageData
won't be available until the next render cycle so your assignment to LandingPage
will be one cycle behind.
You should instead update in one useEffect
and watch for changes to pageData
in another.
const [pageData, setPageData] = useState("");
useEffect(() => {
const getPage = async (id) => {
try {
const response = await api.get(`/landing_pages/${id}`);
console.log("page", response.data); // displays data at the end
setPageData(response.data);
} catch (error) {
console.log(error);
}
};
getPage(pageID);
}, [pageID]);
useEffect(() => {
console.log('Page Data', pageData); // displays updated pageData
let LandingPage = pageData;
const editor = grapesjs.init({
container: "#editor",
components: LandingPage.components || LandingPage.html,
});
}, [pageData]);
