I am trying to make it so that in react-day-picker, only the dates that are available are selectable (i.e. A user is only available for two days, all those other days are disabled and unselectable). I've tried doing this method:
<DayPicker
selectedDays={this.state.selectedDays}
onDayClick={this.handleDayClick}
disabledDays={(day => (day !== ServiceRequestEngagementCreateModal.availableDates(service.available_dates)))}
/>
But that makes all of the dates unavailable.
Any help would be appreciated, thanks!
I figured it out. Heres the code we ended up using
render() {
const availableDateStrings = service.available_dates.map(date => new Date(date.split('-').join(',')).toDateString())
return(
...
<DayPicker
selectedDays={this.state.selectedDays}
onDayClick={this.handleDayClick}
disabledDays={(day => (availableDateStrings.indexOf(day.toDateString()) === -1))}
/>
...
)}

after searching half a day I still not able to getItem from local storage.
the idea is to save some data to local storage and based on that I want to route a user in the Layout component. I am able to save to local storage and delete but not able to get data from it. I get error 'local storage not defined' or 'destroy is not a function'
I have 3 components save, delete and get. save and delete I execute after a client side api call, the get function I need to be working in the Layout as it is the top level for all routes.
I Need a bit help to the right direction please.

I found something that works
export const IsAuth = ()=>{
const [auth, setAuth] = useState();
useEffect(()=>{
if(typeof windows === undefined) return;
const item = localStorage.getItem('ltu');
setAuth(!!item);
},[]);
return auth;
}
now my problem is I have not much understanding of nextjs. I used the Layout to create a theme template, I basically have only 3 pages that can be visited if not logged in and the rest one needs to be logged in. I get so many examples but it seems like I need to verify auth on every single page instead of being able to do this on root/layout level.
all examples I get are without the use of Layout and I am totally stuck.
I want a simple login system just with jwt and check if thats there to show pages.
I could not get the localStorage.getItem() to work in the layout template.
My solution while maybe not perfect is.
in the _app.js I create useState() and pass those along to the menu trough the Layout, in in the menu useEffect() with 'use client' in the useEffect I set the state I need global.
_app.js
export default function App({ Component, pageProps }){
const [isAuth, setAuth] = useState()
const [user, setUser] = useState()
return (
<Layout setAuth={setAuth} isAuth={isAuth} user={user} setUser={setUser}>
<Component user={user} setUser={setUser} isAuth={isAuth} {...pageProps} />
</Layout>
)
}
Layout.js
export default function Layout({ children, setAuth, isAuth, user, setUser }) {
return (
<>
<Headd />
<SideMenu setAuth={setAuth} isAuth={isAuth} user={user} setUser={setUser}/>
<main>
<div className="menu-spacer"></div>
<content>
{children}
</content>
</main>
</>
)
}
menu.js
'use client';
const SideMenu = ({setAuth, isAuth, user, setUser}) => {
useEffect(()=>{
if(typeof windows === undefined) return;
const item = localStorage.getItem('ltu');
setAuth(!!item);
if(item) setUser(JSON.parse(localStorage.getItem('Ud')))
}, [router, router.isReady])
}
Now I can use the {isAuth, user,} on any page and component.
I am pretty sure this is not the right solution, but I could not find any other working solution and no one here yet posted a answer.
Issue:
Right now, I have a dynamic route that fetches data using getServerSideProps(). Within this page, there are multiple tabs that renders different data depending on state (which tab is selected).
I wish to transition from using multiple tabs on this page, to instead using nested routes. However, I am having difficulty obtaining the data originally fetched in these nested routes. Is there an efficient way of doing so, without having to call getServerSideProps() again?
My intended setup looks like this, where [page] calls getServerSideProps():
[page].jsx
|_tab1.jsx
|_tab2.jsx
|_tab3.jsx
My current [page].jsx, where I would like to use separate, nested pages that have access to these props (instead of rendering each tab based on state):
export default function Page(props) {
const [currentTab, setCurrentTab] = useState("home");
return (
<div>
<div id="tab1" onClick={() => setCurrentTab("home")}>
home
</div>
<div id="tab2" onClick={() => setCurrentTab("posts")}>
posts
</div>
<div id="tab3" onClick={() => setCurrentTab("info")}>
info
</div>
{currentTab === "home" ? (
<HomeTab props={props}/>
) : currentTab === "posts" ? (
<PostsTab props={props}/>
) : (
<InfoTab props={props}/>
)}
</div>
);
}
Attempts
I've attempted using the context API to utilize data globally, which my other pages can use. However, this requires the user to visit the original dynamic route first.
Call getServerSideProps() on each nested route. Although this works, I wish to find a better solution, since I'm fetching data on each nested route while the route they're nested under has all of this data available already.
You can use shallow routing in next/route or next/link
Note that, in the below example, I'm using next/link for the demonstration. Without your tab data, I'd assume you have an array of tabs in data
import { useEffect } from 'react'
import Link from 'next/link'
//the path is `/tab/:tabId`
function Tab({ data }) {
const [tabData, setTabData] = useState(data[0]) //first tab data as default for example
useEffect(() => {
setTabData(data[tabId])
}, [router.query.tabId])
return <>
<Link href="/tab/0" shallow />
<Link href="/tab/1" shallow />
<div>
{tabData}
</div>
</>
}
export async function getServerSideProps(context) {
return {
props: {
data: [], //tabs' data you fetched from the API
},
}
}
export default Tab
I am a new programmer and i was following a next js tutorial https://www.youtube.com/watch?v=zueyEdRZQlk&t=127s. It seems that this code does not work anymore. I have been browsing this website for solutions but they are way too advanced for a beginner like me. Can someone please enlighten me on a way to fix this problem.
`
const res = await fetch('https://jsonplaceholder.typicode.com/users');
const data = await res.json();
return {
props: {info: data}
}
`
` {info.map(ninja => (
<div key={ninja.id}>
<a>
<h3>{ninja.name}</h3>
</a>
</div>
))}
</div>
);
please post a minimal reproducible example so we could have a better understanding of what you're asking here ;)
For what I can see, it could be an async issue: is your jsx initialized before you fetch your data ? To be sure your data is well defined before using it, maybe you can try something like :
{Boolean(info) && info.map(ninja => (
<div key={ninja.id}>
<a>
<h3>{ninja.name}</h3>
</a>
</div>
))}
I am using Ant Design and Custom Stylesheet. On first load style is broken, but when I visit another page and come back to broken page, now it looks fine. So the problem is only on the first load. It's on the development server, I have been clear all cache. But still the same issue.
Here is the screenshot how it's looking like after first load
Here is the correct style after I come back from another page
Here is the code how I am rendering the components:
<div>
{jwToken || role === "restaurant_owner" ? (
<Layout>
<Index />
</Layout>
) : (
<div>
<Login />
</div>
)}
</div>
I had a simliar issue, the way I fixed it was to add a mounted variable that depended on the condition. So it looks this.
// Not sure how you pass the condition, I'm assuming hooks
const { condition } = someHook()
const [mounted, setMounted] = useState()
useEffect(() => {
setMounted(true)
return () => setMounted(false)
}, [condition]);
return (
<div>
{mounted && condition && <Component/>
</div>
)
As to why this happens, I suspect it has to do with SSR (I found simliar issue on Github but for Material-UI) and my solution forces the condition to be available only during the browser.
Everything I have tried from what I can find doesn't seem to be working. I'm really curious how to access and edit grandchild objects located in the state with react. If anyone could tell me what I'm doing wrong, it would be very helpful.

Take a look at the following code...
App.js
lines: 41-58
getHomeworld = URL => {
fetch(URL)
.then(res => {
return res.json();
})
.then(homeWorldObject => {
console.log(homeWorldObject);
// this.setState({ <- Why isn't this working????
// ...this.state.starwarsChars,
// ...this.state.nextPage,
// ...this.state.prevPage,
// ...this.state.starwarsChars.homeworld = homeWorldObject
// });
})
.catch(err => {
throw new Error(err);
});
};
lines: 86-89
<CharacterList
characters={this.state.starwarsChars}
getHomeworld={this.getHomeworld}
/>
CharacterList.js
lines: 8-12
<Character
key={character.name}
characterDetails={character}
getHomeworld={props.getHomeworld}
/>
Character.js
lines: 18-29
{Object.keys(props.characterDetails).includes("homeworld") ? (
<div className="character-homeworld">
<Homeworld
homeworld={props.getHomeworld(props.characterDetails.homeworld)}
/>
</div>
) : (
<div className="character-homeworld">
<h4>Homeworld</h4>
<p>None</p>
</div>
)}
Homeworld.js
lines: 7-10
<div className="homeworld-details">
<p>Name: {props.name}</p>
<p>Rotation Period: {props.rotation_period}</p>
</div>
Expected Output:
If you look on the sandbox webpage, the "Name" and "Rotation Period" (Under "Homeworld") should display the values from here: https://swapi.co/api/planets/1/
Is there anyone who can help me figure this out?
EDIT:
I got really close making these changes (using my local machine, the code on the sandbox is still the original)...
App.js
let temp = {...this.state.starwarsChars} // use spread operator to clone it, so you don't mutate state on next line;
for (let character in temp) {
if (temp[character].homeworld === URL) {
temp[character].homeworld = homeWorldObject;
}
}
// console.log(temp);
this.setState({
starwarsChars: temp
});
Character.js
const Character = props => {
props.getHomeworld(props.characterDetails.homeworld);
console.log(props.characterDetails); // returns object{homeworld: {object}}
console.log(props.characterDetails.homeworld); // returns url
and...
<div className="character-homeworld">
<Homeworld
homeworld={props.characterDetails.homeworld}/>
</div>
However, the issue now is if I do console.log(props.characterDetails.homeworld);, it logs homeworld: url
and...
if I do console.log(props.characterDetails);, it logs the property of the character object as homeworld: {object}
...
What I want is the 2nd one, and I'm not sure why it's not consistent.
Update
For some strange reason, codesandbox is console logging both urls, and when I run with yarn start, it logs the url for one, and the object for another. Because of this... I am adding the github link here -> https://github.com/jamespagedev/Sprint-Challenge-React-Wars (so the error can properly be reproduced)
Edit 2:
I changed the sandbox code to the following so we are now only worrying about the code in 1 file -> https://codesandbox.io/s/0mo32q85pp
Here is the issue I am now seeing, and I'm not sure how to solve it...
getHomeworld = URL => {
let home;
fetch(URL)
.then(res => res.json())
.then(homeWorldObject => {
home = homeWorldObject;
console.log(home); // home is an object
});
console.log(home); // why is home undefined?
return home;
};
I've tried doing return homeWorldObject, but the main function just returns undefined. After doing the console logging, that was what I found, and I'm not sure why that is happening...
