post request in Next.js is not working properly - javascript

In Next.js I'm trying to POST data in MongoDB using react-query and useMutation
I've structured my endpoints in api/users/index.js
import connectDB from "../../../db/connectDB";
import {getUsers, postUser, updateUser, deleteUser} from "../../../db/controllers/AddedUserController";
/**
* #param {import('next').NextApiRequest} req
* #param {import('next').NextApiResponse} res
*/
export default async function handler(req, res) {
await connectDB().catch(() => res.status(405).json({error: "Connection Error"}))
const {method} = req
switch(method) {
case "GET":
await getUsers(req, res)
break;
case "POST":
await postUser(req, res)
break;
case "PUT":
await updateUser(req, res)
break;
case "DELETE":
await deleteUser(req, res)
break;
default:
res.setHeader("Allow", ["GET", "POST", "PUT", "DELETE"])
res.status(405).end(`Method ${method} not allowed`)
}
}
So if the method equals to POST it calls this endpoint in db/controllers/AddedUserController.js
/*** POST http://localhost:3000/api/users ***/
export async function postUser(req, res) {
try {
const {formData} = req.body
console.log("API", formData)
if(!formData || formData === undefined) return res.status(404).json({error: "Form data not provided"})
await AddedUser.create(formData, function(err, data){
return res.status(200).json(data)
});
} catch(error) {
res.status(404).json(error)
}
}
Finally I call this endpoint with this helper function
/*** POST new user ***/
export const addUser = async (formData) => {
const Options = {
method: "POST",
headers: {'Content-Type': 'application/json'},
body: JSON.stringify(formData)
}
try {
const response = await fetch(`${BASE_URL}/api/users`, Options)
const json = await response.json()
return json
} catch(error) {
console.log(error)
return error
}
}
Then in my AddingForm.js component I call the helper function using useMutation
/*** components ***/
import {Button, InputGroup} from "../index";
import {useMutation} from "react-query";
import {addUser} from "../../../utils/helpers/helper";
import {useState} from "react";
const AddingForm = () => {
const [name, setName] = useState("")
const [email, setEmail] = useState("")
const addMutation = useMutation(addUser)
const newUser = async (e, formData) => {
e.preventDefault()
await addMutation.mutate(formData)
}
return (
<>
<form onSubmit={(e) => newUser(e, {name, email})}>
<InputGroup
label="Name"
name="name"
value={name}
onChange={(e) => setName(e.target.value)}
/>
<InputGroup
label="Email"
name="email"
value={email}
onChange={(e) => setEmail(e.target.value)}
/>
<Button className="bg-gray-200" type="submit">Aggiungi</Button>
</form>
</>
)
}
export default AddingForm;
But I got a 404 error with the message "Form data not provided" from db/controllers/AddedUserController.js
if(!formData || formData === undefined) return res.status(404).json({error: "Form data not provided"})
Why is this happening??

how to update fetch with useLoaderData() using react-router?

I would like to update the data of useLoaderData() after submit a form.
In my case :
export const countriesLoader = async () => {
const res = await fetch("https://restcountries.com/v3.1/all/");
if (!res.ok) {
throw Error("Could not reach the data !");
}
return res.json();
};
<Route index element={<CoutriesList />} loader={countriesLoader} />
on CountriesList element :
const countries = useLoaderData();
new data that i would like to update in countries useLoaderData() :
const findCountry = async () => {
const res = await fetch(
`https://restcountries.com/v3.1/name/${searchText}`
);
const data = res.json();
return data;
};
So when I submit, I would like that the data of countriesLoader to become the data from findCountry.
any solution ? thanks
I think you may be looking to use findCountry as a route action when a form is submitted. Loaders run when a route is loaded for the first time. An action can be dispatched later.
Basic Example:
const router = createBrowserRouter([
{
index: true,
element: <CountriesList />,
loader: countriesLoader,
action: findCountry
}
]);
<RouterProvider router={router} />
const countriesLoader = async () => {
const res = await fetch("https://restcountries.com/v3.1/all/");
if (!res.ok) {
throw Error("Could not reach the data !");
}
return res.json();
};
const findCountry = async ({ request }) => {
const formData = await request.formData();
const res = await fetch(
`https://restcountries.com/v3.1/name/${formData.get("country")}`
);
if (!res.ok) {
throw Error("Could not reach the data !");
}
return res.json();
};
import {
Form,
useActionData,
useLoaderData
} from "react-router-dom";
const CountriesList = () => {
const searchResult = useActionData();
const countriesData = useLoaderData();
return (
<>
...
<Form method="post" replace>
<label>
Search <input required type="text" name="country" />
</label>
<button type="submit">Create</button>
</Form>
...
</>
);
};

How to make react component call an axios HTTP request

I am trying to make a section for my website with a news bar that contains snippets of update posts for my site. To do so, I have successfully created the data schema, routing on my backend for post and get requests. I am routing requests on the client server using axios for my XMLHTTPRequests, Redux for my global state store, and cors. Using my NewsBar component, I wrap my NewsPosts component, which is a collection of rendered NewsPost components.
NewsBar component:
function useQuery() {
return new URLSearchParams(useLocation().search);
}
const NewsBar = () => {
const classes = useStyles();
const query = useQuery();
const page = query.get('page') || 1;
const searchQuery = query.get('searchQuery');
const [currentId, setCurrentId] = useState(0);
console.log(`NewsBar: ${useLocation().search} | query=>${query}`);
console.log(`searchquery: ${searchQuery}`);
return (
<>
<Grow in>
<Grid container direction={'row'} className={classes.newsBar} justifyContent='center'>
<Typography variant='h3'>News Bar</Typography>
<Grid item>
<NewsPosts setCurrentId={setCurrentId} />
</Grid>
</Grid>
</Grow>
</>
)
}
export default NewsBar;
NewsPosts component:
const NewsPosts = ({ setCurrentId }) => {
const { newsPosts, isLoading } = useSelector((state) => state.newsPosts);
const classes = useStyles();
newsPosts.map((newsPost) => {
console.log(newsPost);
})
console.log(new Date().toISOString());
console.log(`newsPosts array: ${typeof newsPosts} ${newsPosts}`)
if (!newsPosts.length && !isLoading) return 'No news posts.';
return (
isLoading ? <LinearProgress /> : (
<Grid container alignItems='stretch' spacing={3}>
{newsPosts?.map((newsPost) => (
<Grid key={newsPost._id} item xs={12} sm={12} md={12} lg={12}>
<NewsPost newsPost={newsPost} setCurrentId={setCurrentId}/>
</Grid>
))}
</Grid>
)
);
};
export default NewsPosts;
I added console logging for each of my routing actions and methods, and unfortunately it seems as though I get an empty array of type Object instead of the page of documents I am supposed to get. Within my console, the only logs that output are from NewsPosts.js.
NewsBar: | query=>
NewsBar.js:27 searchquery: null
NewsPosts.js:17 2022-12-01T20:36:08.958Z
NewsPosts.js:18 newsPosts array: object
On top of that, I checked my network requests and none were made. Could someone attempt to tell me why this is?
Axios code as per request:
import { START_LOADING, END_LOADING, FETCH_POST, FETCH_ALL, DELETE, CREATE } from "../constants/actionTypes";

} catch (error) {
console.log(error);
}
};

I am not succeeding in checking my input file

What check did I miss that my edit page only works if it has a file selected?
I tried to make some conditionals in the onSubmit function but I haven't found the way yet.
I know it has to do with the image array because when I click edit without selecting a file I get this error:

Uncaught (in promise) Error: Invalid hook call. Hooks can only be called inside of the body of a function component. - useEffect()

I get this error when I try and call a function I have imported within my useEffect() hook in Dashboard.jsx. I am just trying to pull in data from database on the page load pretty much so that when user click button they can send off correct credentials to the api.
I am pulling it in from database for security reasons, so client id is not baked into the code.
I am pretty sure that I am getting this error maybe because the function is not inside a react component? although I am not 100% sure. And if that is the case I am not sure of the best way to restructure my code and get the desired output.
Code below.

export default Dashboard;
the error is because you’re calling const {setMavenlinkClientId} = useContext(AppContext) inside the file mavenlinkCredentials.js which is not a react components.
you could maybe change the function inside mavenlinkCredentials.js to accept a setMavenlinkClientId and pass it from outside like this.
const GetMavenlinkClientId = async (setMavenlinkClientId) => {
const mavenlinkRef = doc(db, 'mavenlink', 'application_id');
const mavenlinkDocSnap = await getDoc(mavenlinkRef)
if(mavenlinkDocSnap.exists()){
console.log("mavenlink id: ", mavenlinkDocSnap.data());
console.log(mavenlinkDocSnap.data()['mavenlinkAccessToken'])
setMavenlinkClientId(mavenlinkDocSnap.data()['application_id'])
} else {
console.log("No doc");
}
}
and then you can call this function in your dashboard.js like so,
const {setMavenlinkClientId} = useContext(AppContext)
if(isAuthenticated){
GetMavenlinkClientId(setMavenlinkClientId)
}

why is my response.data empty? trying to display data from mongoDB

I'm working on a reviews feature and I'm trying to access data from my MongoDB database and display it in my comment in react. However when I load the page its empty and nothing displays. I console logged my reponse.data and found out the array is empty and I'm unsure why.
