I am struggling with this async await issue I have created async function and for that I am calling await but I am getting error Unexpected reserved word 'await'
Below is the async function
export const addProductCall = async (product) => {
let accessToken = window.localStorage.getItem("accessToken");
await axios.post(SERVER_URI + '/inventoryservice/v1/item',
product,
{ headers: { "Authorization": "Bearer " + accessToken, "Content-Type": "application/json" } })
}
Below is the function from where I am calling this function.
const handleSubmit = () => {
const data = {
'storeId': customerDetails.id, category, categoryToBeAdded, description,
productCode, productName, sku, price, unit, quantity
}
await addProductCall(data);
}
You cannot use the await keyword outside of an async function :
const handleSubmit = () => {
const data = {
'storeId': customerDetails.id, category, categoryToBeAdded, description,
productCode, productName, sku, price, unit, quantity
}
await addProductCall(data);
}
should be :
const handleSubmit = async () => {
const data = {
'storeId': customerDetails.id, category, categoryToBeAdded, description,
productCode, productName, sku, price, unit, quantity
}
await addProductCall(data);
}
Replace
const handleSubmit = () => {
with
const handleSubmit = async () => {
For await to work, it needs to be wrapped inside an async function

The question is pretty self-explanatory but I wanna know how to deal with scheduled tasks whether it is cron, setTimeout, setInterval etc. Let's say I have multiple variables initialized inside it. If the task keeps repeating is it gonna keep filling memory or will it clean itself after some time? This might sound simple but I'm a beginner. I will throw my code here where I send one API request to check the value of one variable and another one to increase it by one. I can probably safely take some of the variables outside just fine but the question remains the same.
const { GraphQLClient, gql } = require ('graphql-request')
const Cron = require ('croner')
const job = Cron('0 14 * * *', () => {
async function main() {
console.log("start")
const endpoint = 'https://graphql.anilist.co/'
const graphQLClient = new GraphQLClient(endpoint, {
headers: {
authorization: 'Token hidden for obvious reasons.',
},
})
const query_check = gql`
mutation ($mediaId: Int, $status: MediaListStatus) {
SaveMediaListEntry (mediaId: $mediaId, status: $status) {
id
status
progress
}
}
`
const variables = {
mediaId: "1337"
}
const check = await graphQLClient.request(query_check,variables)
console.log(`przed ${check.SaveMediaListEntry.progress}`)
const query_new = gql`
mutation ($mediaId: Int, $status: MediaListStatus, $progress: Int) {
SaveMediaListEntry (mediaId: $mediaId, status: $status, progress: $progress) {
id
status
progress
}
}
`
const new_variables = {
mediaId: `1337`,
progress: `${check.SaveMediaListEntry.progress + 1}`
}
const new_query = await graphQLClient.request(query_new,new_variables)
console.log(`po ${new_query.SaveMediaListEntry.progress}`)
}
main().catch((error) => console.error(error))
});

const RequestStatus = () => {
const status = 'SUCCESS'
const object = {
SUCCESS: console.log('Success'),
PROGRESS: console.log('Progress'),
ERROR: console.log('Errror'),
}
useEffect(() => {
setTimeout(() => {
return object[status]
}, 5000)
}, [status])
}
You see all three statuses logged because you are calling all console.log when you create your object
Here are two ways you can modify your code to fix this
In the first method (which is the one I recommend) I am mapping the messages to the status codes and getting the approprite message using object[status]
const RequestStatus = () => {
const status = 'SUCCESS'
const object = {
SUCCESS: 'Success',
PROGRESS: 'Progress',
ERROR: 'Errror',
}
useEffect(() => {
setTimeout(() => {
console.log(object[status]);
}, 5000)
}, [status])
}
In the second one I create lambda functions for each status code that define what happens when that status code occurs
const RequestStatus = () => {
const status = 'SUCCESS'
const object = {
SUCCESS: ()=>{console.log('Success')},
PROGRESS: ()=>{console.log('Progress')},
ERROR: ()=>{console.log('Errror')},
}
useEffect(() => {
setTimeout(() => {
object[status]();
}, 5000)
}, [status])
}

try {
console.log('11111')
const {
data: { tasks },
} = await axios.get('/api/v1/tasks')
console.log('22222 ' + await axios.get('/api/v1/tasks') )
console.log('33333 ' + tasks)
Issue is: tasks is undefined
The problem was in Backend..
the route associated with await axios.get('/api/v1/tasks') i.e get('/api/v1/tasks') had this code
``` const getAllTasks = async (req,res) => {
try{
const tasks = await Task.find({})
res.status(200).json(tasks)
}
catch(error){
res.status(500).send({msg: error})
}
}```
instead above. It should be
```const getAllTasks = async (req,res) => {
try{
const tasks = await Task.find({})
res.status(200).json({ tasks })
}
catch(error){
res.status(500).send({msg: error})
}
}```
The change is in res.status(200).json({ tasks })

In postman when i use the url below the news property on the response in full with articles
https://api.currentsapi.services/v1/search?country=us&language=en&apiKey="..."
But in javascript I'm getting an empty news array.
Here is the javascript:
function displayNewsResults(responseJson){
console.log(responseJson)
}
let newsBaseUrl = 'https://api.currentsapi.services/v1/search'
let newsApiKey = '...';
function getNews(country) {
let params = {
country: country,
language: 'us',
apiKey: newsApiKey
}
let queryString = formatQueryParams(params);
let url = newsBaseUrl + '?' + queryString;
console.log(url)
let req = new Request(url);
fetch(req)
.then(response => {
if (response.ok) {
return response.json();
}
else {
throw new Error(response.statusText);
}
})
.then(responseJson => displayNewsResults(responseJson))
.catch(err => {
$('#js-error-message-news').empty().text(`Something went wrong: ${err.message}`).show();
})
}
The function displayNewsResults returns:
{status: "ok", news: Array(0), page: 1}
The code seems correct and the result is also correct, the mistake however is that in your code you're calling the API with the language parameter set to us instead of en

I have this sort of code. When I search find()... It does not work while searching with findOne()... is working.
Thanks for your answer!
const task = await Task.find({_id, owner: req.user._id}) //This does not work
const task = await Task.findOne({_id, owner: req.user._id}) // This works
router.patch('/tasks/:id', auth, async (req, res) => {
const updates = Object.keys(req.body) // The opposite is Object.values()
const _id = req.params.id
const allowedUpdates = ['description', 'completed']
const isValidOperation = updates.every((update) => allowedUpdates.includes(update))
if (!isValidOperation) {
return res.status(400).send({error: 'Invalid update!'})
}
try {
const task = await Task.findOne({_id, owner: req.user._id})
if (!task) {
return res.status(404).send()
}
updates.forEach((update) => task[update] = req.body[update])
await task.save()
res.send(task)
} catch (e) {
res.status(500).send(e)
}
})
at first, you should use the same syntax to show an error when it coming it the no result may be because the condition isenter image description here not an achievement.
