Please I need assistance with a code.
I have a Nextjs dynamic page as my 'stripe_success_url'
Initially I had one product 'courses' whose {id} is beign fetched in the router.query
however, i have created a new product 'ebook' whose {id} is also being fetched in the router.query
I edited the code to differentiate course ID and ebook ID but it is not working yet.
const StripeSuccess = () => {
// state
const [course, setCourse] = useState([]);
const [ebook, setEbook] = useState([]);
const router = useRouter();
const { id } = router.query;
useEffect(() => {
const fetchCourses = async () => {
const { data } = await axios.get('/api/courses');
setCourse(data);
//console.log(data);
};
fetchCourses();
}, [id]);
useEffect(() => {
const fetchEbooks = async () => {
const { data } = await axios.get('/api/ebooks');
setEbook(data);
//console.log(data);
};
fetchEbooks();
}, [id]);
useEffect(() => {
if (id === `${course._id}`) {
const successRequest = async () => {
const { data } = await axios.get(`/api/stripe-success/${id}`);
//console.log(data);
//console.log('SUCCESS REQ DATA', data);
router.push(`/user/course/${data.course.slug}`);
};
successRequest();
}
}, [id]);
useEffect(() => {
if (id === `${ebook._id}`) {
const successEbookRequest = async () => {
const { data } = await axios.get(`/api/stripe-ebooksuccess/${id}`);
//console.log(data);
//console.log('SUCCESS REQ DATA', data);
router.push(`/user/course/${data.ebook.slug}`);
};
successEbookRequest();
}
}, [id]);
Im working on a star wars api app. I am getting an array of people objects, 10 characters. Who all are their own object with different values. However homeworld, and species are urls. So I have to fetch them and store that data to the correct place. I figured out a way to get the homeworld values to each character. However when I try to do it with species I receive undefined. Would appreciate any help this has been kind of a pain thanks ahead of time !
const [people, setPeople] = useState([]);
const [homeWorld, setHomeWorld] = useState([]);
const [species, setSpecies] = useState([]);
const [nextPageUrl, setNextPageUrl] = useState("https://swapi.dev/api/people/");
const [backPageUrl, setBackPageUrl] = useState('');
const [test, setTest] = useState([]);
const fetchPeople = async () => {
const { data } = await axios.get(nextPageUrl);
setNextPageUrl(data.next);
setBackPageUrl(data.previous);
return data.results;
}
const backPage = async () => {
const { data } = await axios.get(backPageUrl);
setCharacters(data.results);
setNextPageUrl(data.next);
setBackPageUrl(data.previous);
}
// Get People
async function getPeople() {
const persons = await fetchPeople();
const homeWorldUrl= await Promise.all(
persons.map((thing) => axios.get(thing.homeworld)),
);
const newPersons = persons.map((person) => {
return {
...person,
homeworld: homeWorldUrl.find((url) => url.config.url === person.homeworld)
};
});
const newPersons2 = newPersons.map((person) => {
return {
...person,
homeWorld: person.homeworld.data.name
};
});
setPeople(newPersons2);
}
// Get Species
async function getSpecies() {
const persons = await fetchPeople();
const speciesUrl = await Promise.all(
persons.map((thing) => axios.get(thing.species)),
);
const newSwapi = persons.map((person) => {
return {
...person,
species: speciesUrl.find((info) => info.data.url === person.species)
};
});
setTest(newSwapi);
// const newPersons2 = newPersons.map((person) => {
// return {
// ...person,
// homeWorld: person.homeworld.data.name
// };
// });
}
useEffect(() => {
getPeople();
getSpecies();
// eslint-disable-next-line react-hooks/exhaustive-deps
}, []); ```
Species property of person is a array, so your getSpecies() should be like
async function getSpecies() {
const persons = await fetchPeople();
const speciesUrl = await Promise.all(
persons
.filter((thing) => thing.species.length)
.map((thing) => axios.get(thing.species[0]))
);
const newSwapi = persons.map((person) => {
return {
...person,
species: speciesUrl.find((info) => info.data.url === person.species[0])
};
});
setTest(newSwapi);
}

}

});
}, [auth])
const setUserName = () => {
updateProfile(auth.currentUser, {
displayName: name
});
Before displayName property being updated its redirecting to the route it came from. Is this happening for asynchronous nature?
I'm trying to set the displayName property on the navbar.displayName is getting set but not showing on ui, but showing after when I refresh the page. How can I fix this issue?
Hello I'm trying to display data from firebase, it works very well but when I add the condition where() to compare uid to the id present in my database
However in the console.log, it appears well, it's as if between the user request and the getOrders() request; the delay was too short and that he didn't have time to find uid
const [orders, setOrders] = useState([]);
const [user, setUser] = useState('');
useEffect( () => {
fire.auth().onAuthStateChanged((user) => {
if (user) {
setUser(user);
console.log(user);
} else {
setUser(null);
}
});
getOrders();
}, []);
function getOrders() {
fire.firestore().collection("orders")
.where('uid', '==', `${user.uid}`)
.where('statut', '==', 'Active')
.onSnapshot(function (querySnapshot) {
setOrders(
querySnapshot.docs.map((doc) => ({
id: doc.id,
orderid: doc.data().id,
statut: doc.data().statut,
nomproduit: doc.data().nomproduit
}))
);
});
}
Thank you for help.
Consider passing the uid as an argument into getOrders() and call it when the user is ready. Like this
const [orders, setOrders] = useState([]);
const [user, setUser] = useState('');
useEffect( () => {
fire.auth().onAuthStateChanged((user) => {
if (user) {
setUser(user);
console.log(user);
getOrders(user.uid);
} else {
setUser(null);
}
});
}, []);
function getOrders(uid) {
fire.firestore().collection("orders")
.where('uid', '==', `${uid}`)
.where('statut', '==', 'Active')
.onSnapshot(function (querySnapshot) {
setOrders(
querySnapshot.docs.map((doc) => ({
id: doc.id,
orderid: doc.data().id,
statut: doc.data().statut,
nomproduit: doc.data().nomproduit
}))
);
});
}
Another thing you could do would be to pass user as a dependency into the useEffect() hook like this
useEffect( () => {
fire.auth().onAuthStateChanged((user) => {
if (user) {
setUser(user);
console.log(user);
} else {
setUser(null);
}
});
getOrders();
}, [user]);
This will cause the useEffect to run again when the user has changed. Not the best approach tho, performance wise, just FYI.
I have several functional components which share the same logic. So I would like to refactor them using React hooks. All of them make some calls to the server on mount to check if the order has been paid. If yes, paid state is set to true , and a file is being downloaded. On submit I check if paid state is set to true, if yes, the same file is being downloaded, if not, a new order is created and a user is being redirected to a page with a payment form.
I have already extracted all functions (getOrder(), getPaymentState(), createOrder(), initPayment() and downloadFile()) which make API calls to the server. How can I further optimize this code, so that I could move checkOrder(), checkPayment(), downloadPDF() and newOrder() outside the component to use the same logic with other components as well?
Here is my component:
const Form = () => {
const [paid, setPaid] = useState(false);
const [submitting, setSubmitting] = useState(false);
const [loading, setLoading] = useState(false);
const [data, setData] = useState({});
const checkOrder = async () => {
let search = new URLSearchParams(window.location.search);
let success = search.get("Success");
if (success) {
try {
const data = await getOrder();
setData(data);
checkPayment(data);
} catch (err) {
alert(err.message)
}
}
};
const checkPayment = async values => {
try {
const paid = await getPaymentState();
setPaid(paid);
downloadPDF(values);
} catch (err) {
alert(err.message)
}
};
const downloadPDF = async values => {
setLoading(true);
let downloadData = {
email: values.email,
phone: values.phone
}
const response = await downloadFile(downloadData, sendURL);
setLoading(false);
window.location.assign(response.pdf);
}
const newOrder = async values => {
setSubmitting(true);
const order = await createOrder(values, description, sum);
const paymentUrl = await initPayment(order, description, sum, returnURL);
setSubmitting(false);
window.location.assign(paymentUrl);
}
const onSubmit = async values => {
if (paid) {
try {
downloadPDF(data);
} catch (err) {
console.log(err);
}
} else {
try {
newOrder(values)
} catch (err) {
alert(err.message)
}
}
};
useEffect(() => {
checkOrder();
}, []);
return (
)
}
EDIT 1: I also need to be able to pass some data to this hook: downloadData, sendURL, description, sum and returnURL, which will be different in each case. downloadData then needs to be populated with some data from the values.
I would appreciate if you could point me at the right direction. I'm just learning React and I would really like to find the correct way to do this.
EDIT 2: I've posted my own answer with the working code based on the previous answers. It's not final, because I still need to move downloadPDF() outside the component and pass downloadData to it, but when I do so, I get an error, that values are undefined. If anybody can help me with that, I will accept it as an answer.
I made a quick refactor of the code and put it in a custom hook, it looks like search param is the key for when the effect needs to run.
const useCheckPayment = (search) => {
const [paid, setPaid] = useState(false);
const [submitting, setSubmitting] = useState(false);
const [loading, setLoading] = useState(false);
const [data, setData] = useState({});
const checkOrder = useCallback(async () => {
let paramSearch = new URLSearchParams(search);
let success = paramSearch.get('Success');
if (success) {
try {
//why not just pass it, makes getOrder a little less impure
const data = await getOrder(paramSearch);
setData(data);
checkPayment(data);
} catch (err) {
alert(err.message);
}
}
}, [checkPayment, search]);
const checkPayment = useCallback(async (values) => {
try {
const paid = await getPaymentState();
setPaid(paid);
downloadPDF(values);
} catch (err) {
alert(err.message);
}
}, []);
const downloadPDF = async (values) => {
setLoading(true);
const response = await downloadFile();
setLoading(false);
window.location.assign(response.pdf);
};
const newOrder = async (values) => {
setSubmitting(true);
const order = await createOrder();
const paymentUrl = await initPayment(order);
setSubmitting(false);
window.location.assign(paymentUrl);
};
const onSubmit = useCallback(
async (values) => {
if (paid) {
try {
downloadPDF(data);
} catch (err) {
console.log(err);
}
} else {
try {
newOrder(values);
} catch (err) {
alert(err.message);
}
}
},
[data, paid]
);
useEffect(() => {
checkOrder();
}, [checkOrder]); //checkOrder will change when search changes and effect is called again
return { onSubmit, submitting, loading };
};
const Form = () => {
const { onSubmit, submitting, loading } = useCheckPayment(
window.location.search
);
return '';
};
You can extract out all the generic things from within the Form component into a custom Hook and return the required values from this hook
The values which are dependencies and will vary according to the component this is being called from can be passed as arguments to the hook. Also the hook can return a onSubmit function to which you can pass on the downloadData
const useOrderHook = ({returnURL, sendURL, }) => {
const [paid, setPaid] = useState(false);
const [submitting, setSubmitting] = useState(false);
const [loading, setLoading] = useState(false);
const [data, setData] = useState({});
const checkOrder = async () => {
let search = new URLSearchParams(window.location.search);
let success = search.get("Success");
if (success) {
try {
const data = await getOrder();
setData(data);
checkPayment(data);
} catch (err) {
alert(err.message)
}
}
};
const checkPayment = async values => {
try {
const paid = await getPaymentState();
setPaid(paid);
downloadPDF(values);
} catch (err) {
alert(err.message)
}
};
const downloadPDF = async values => {
setLoading(true);
let downloadData = {
email: values.email,
phone: values.phone
}
const response = await downloadFile(downloadData, sendURL);
setLoading(false);
window.location.assign(response.pdf);
}
const newOrder = async (values, description, sum) => {
setSubmitting(true);
const order = await createOrder(values, description, sum);
const paymentUrl = await initPayment(order, description, sum, returnURL);
setSubmitting(false);
window.location.assign(paymentUrl);
}
const onSubmit = async ({values, downloadData: data, description, sum}) => {
if (paid) {
try {
downloadPDF(data);
} catch (err) {
console.log(err);
}
} else {
try {
newOrder(values, description, sum)
} catch (err) {
alert(err.message)
}
}
};
useEffect(() => {
checkOrder();
}, []);
return {onSubmit, loading, submitting, paid, data };
}
Now you can use this hook in component like Form as follows
const Form = () => {
const {onSubmit, newOrder, loading, submitting, paid, data } = useOrderHook({returnUrl: 'someUrl', sendURL: 'Some send URL'})
const handleSubmit = (values) => {
// since this function is called, you can get the values from its closure.
const data = {email: values.email, phone: values.phone}
onSubmit({ data, values, description, sum})// pass in the required values for onSubmit here. you can do the same when you actually call newOrder from somewhere
}
// this is how you pass on handleSubmit to React-final-form
return <Form
onSubmit={handleSubmit }
render={({ handleSubmit }) => {
return <form onSubmit={handleSubmit}>...fields go here...</form>
}}
/>
}
Based on the answers above I came up with the following code.
The hook:
const useCheckPayment = ({initialValues, sendUrl, successUrl, description, sum, downloadPDF}) => {
const [paid, setPaid] = useState(false);
const [loading, setLoading] = useState(false);
const [submitting, setSubmitting] = useState(false);
const [data, setData] = useState(initialValues);
const checkOrder = useCallback(
async () => {
let search = new URLSearchParams(window.location.search);
let success = search.get('Success');
if (success) {
try {
const data = await getOrder(search);
setData(data);
checkPayment(search);
} catch (err) {
alert(err.message);
}
}
}, [checkPayment]
);
const checkPayment = useCallback(
async (search) => {
try {
const paid = await getPaymentState(search);
setPaid(paid);
document.getElementById('myForm').dispatchEvent(new Event('submit', { cancelable: true }))
} catch (err) {
alert(err.message);
}
}, []
);
const newOrder = useCallback(
async (values) => {
setSubmitting(true);
const order = await createOrder(values, description, sum);
const paymentUrl = await initPayment(order, description, sum, successUrl);
setSubmitting(false);
window.location.assign(paymentUrl);
}, [description, sum, successUrl]
);
const downloadPDF = async (values, downloadData) => {
setLoading(true);
const response = await downloadFile(downloadData, sendUrl);
setLoading(false);
window.location.assign(response.pdf);
};
const onSubmit = useCallback(
async ({ values, downloadData }) => {
if (paid) {
try {
downloadPDF(values, downloadData);
} catch (err) {
console.log(err);
}
} else {
try {
newOrder(values);
} catch (err) {
alert(err.message);
}
}
},
[paid, downloadPDF, newOrder]
);
useEffect(() => {
checkOrder();
}, [checkOrder]);
return { onSubmit, submitting };
};
The component:
const sendUrl = 'https://app.example.com/send'
const successUrl = 'https://example.com/success'
const description = 'Download PDF file'
const sum = '100'
const Form = () => {
const handleSubmit = (values) => {
const downloadData = {
email: values.email,
phone: values.phone
}
onSubmit({ downloadData, values })
}
const { onSubmit, submitting } = useCheckPayment(
{sendUrl, successUrl, description, sum}
);
return (
<Form
onSubmit={handleSubmit}
render={({ handleSubmit }) => (
<form onSubmit={handleSubmit}></form>
)}
/>
)
}
