update the user value in the next auth session when updating data - authentication

I have a page to update user data, everything is running correctly and the data has changed with the latest in the database. But the value in the next auth session does not change, how to synchronize the newly updated user data with the user data in the next auth session

First you have to update the data on [...nextauth].js
It keeps track of user with the server session, but you want fresh data from your server. Here is how I did it :
callbacks.session = async function session({ session, token }) {
// we can fetch info from back end here to add it to the sessio
session.user = token.user;
session.jti = token.jti;
// If user is logged, we refresh his session
if (token?.user?.id) {
const url =
routes.api.entities.shop.get.byId.build(token?.user?.id);
let apiResp = await axios.get(url, {});
session.user = { ...apiResp.data };
token.user = { ...apiResp.data };
}
return session;
};
So here, the session that should have been the old one of the server is replaced by the one of my DB.
Then, you have to update it client side.
The data on client side does update if you click on another tab and click again on your tab.
It seems useless, but what about automating it ?
Just use this :
const reloadSession = () => {
const event = new Event("visibilitychange");
document.dispatchEvent(event);
};
And calling it directly on your react page will update everything.
reloadSession();

useInfiniteScroll utility of Vueuse is fetching same items again

Here is a reproducable stackblitz -
https://stackblitz.com/edit/nuxt-starter-jlzzah?file=components/users.vue
What's wrong? -
My code fetches 15 items, and with the bottom scroll event it should fetch another 15 different items but it just fetches same items again.
I've followed this bottom video for this implementation, it's okay in the video but not okay in my stackblitz code:
https://www.youtube.com/watch?v=WRnoQdIU-uE&t=3s&ab_channel=JohnKomarnicki
The only difference with this video is that he's using axios while i use useFetch of nuxt 3.
It's not really a cache issue. useFetch is "freezing" the API URL, the changes you make to the string directly will not be reliably reflected. If you want to add parameters to your API URL, use the query option of useFetch. This option is reactive, so you can use refs and the query will update with the refs. Alternatively, you can use the provided refresh() method
const limit = ref(10)
const skip = ref(20)
const { data: users, refresh: refreshUsers } = await useFetch(
'https://dummyjson.com/users',
{
query:{
limit,
skip
}
}
);
//use the data object directly to access the result
console.log(users.value)
//if you want to update users with different params later, simply change the ref and the query will update
limit.value = 23
//use refresh to manually refresh the query
refreshUsers()
This results in a first API call http://127.0.0.1:8000/api/tasks?limit=10&skip=20 and then a second with the updated values http://127.0.0.1:8000/api/tasks?limit=23&skip=20
You can leave the cache alone, as it is just a workaround, and will not work reliably.
[Updated] The useFetch() documentation is now updated as described below.
The query option is not well documented yet, as discussed in this nuxt issue. I've created a pull request on nuxt/framework to have it reflected in the documentation. Please see a full explanation below:
Using the query option, you can add search parameters to your query. This option is extended from unjs/ohmyfetch and is using ufo to create the URL. Objects are automatically stringified.
const param1 = ref('value1')
const { data, pending, error, refresh } = await useFetch('https://api.nuxtjs.dev/mountains',{
query: { param1, param2: 'value2' }
})
This results in https://api.nuxtjs.dev/mountains?param1=value1&param2=value2
Nuxt3's useFetch uses caching by default. Use initialCache: false option to disable it:
const getUsers = async (limit, skip) => {
const { data: users } = await useFetch(
`https://dummyjson.com/users?limit=${limit}&skip=${skip}`,
{
initialCache: false,
}
);
//returning fetched value
return users.value.users;
};
But you probably should use plain $fetch instead of useFetch in this scenario to avoid caching:
const getUsers = async (limit, skip) => {
const { users } = await $fetch(
`https://dummyjson.com/users?limit=${limit}&skip=${skip}`
);
//returning fetched value
return users;
};

Cookie values do not get properly updated - Vue cookies

Here's what I want to do:
I am looking to store user preferences (Possibly 2-3 users max) in a cookie so they are readily available.
Upon login, I check if I have an existing 'users' cookie and if not, I create it. If it exists, I check if my current user is inside this cookie. If not, I add him, with empty prefs.
vue: 2.4.16
vue-cookies: 1.7.4
loggedIn (userId) {
this.profile = userId
this.userConnected = true
if (this.$cookies.isKey('users')) {
const userBase = JSON.parse(this.$cookies.get('users'))
const found = userBase.findIndex(user => user.profile === this.profile)
if (found === -1) {
console.log('new user, add to cookie')
const newUser = {
profile: this.profile,
preferences: {
cursor: null,
wallpaper: null,
theme: null
}
}
userBase.push(newUser)
this.$cookies.set('users', JSON.stringify(userBase), 604800)
}
} else {
console.log('no cookie, create users cookie')
const newUsers = [
{
profile: this.profile,
preferences: {
cursor: null,
wallpaper: null,
theme: null
}
}
]
this.$cookies.set('users', JSON.stringify(newUsers), 604800)
}
So far so good. Everything seems to work properly.
I then have my function to update preferences and update the cookie. The problem occurs when I have more than one users in my cookie. The first object in my cookie array will always get modified properly, but any other user in the Array will be ignored completely. This only happens with the cookie, the data that I'm pushing into the cookie is looking good. Here's more details:
updatePreferences (preference, data) {
//- We are getting the Users cookie, and finding the current active user
const globalPreferences = JSON.parse(this.$cookies.get('users'))
const userIndex = globalPreferences.findIndex(user => user.profile === this.$store.state.User.userProfile)
const currentUser = globalPreferences[userIndex]
if (preference === 'wallpaper') {
currentUser.preferences.wallpaper = data
globalPreferences.splice(userIndex, 1, currentUser)
//- globalPreferences is always properly updated. The console log always reflects the changes
const updatedData = JSON.stringify(globalPreferences)
//- The cookie does not properly update. Only the first index ever gets updated, the rest never changes.
this.$cookies.set('users', updatedData, 604800)
}
}
I am definitely lost here. I have tried removing the cookie before updating it again, but without luck either. Any help would be appreciated. Thanks!
First user update - Console log (Works properly)
Second user update - Console log (Cookie does not update value)
The data I was trying to push into the cookie was too big. I'm gonna use localStorage for now as it properly updates my data, and will make sure to clean the unused informations.

A better way to handle async saving to backend server and cloud storage from React Native app

In my React Native 0.63.2 app, after user uploads images of artwork, the app will do 2 things:
1. save artwork record and image records on backend server
2. save the images into cloud storage
Those 2 things are related and have to be done successfully all together. Here is the code:
const clickSave = async () => {
console.log("save art work");
try {
//save artwork to backend server
let art_obj = {
_device_id,
name,
description,
tag: (tagSelected.map((it) => it.name)),
note:'',
};
let img_array=[], oneImg;
imgs.forEach(ele => {
oneImg = {
fileName:"f"+helper.genRandomstring(8)+"_"+ele.fileName,
path: ele.path,
width: ele.width,
height: ele.height,
size_kb:Math.ceil(ele.size/1024),
image_data: ele.image_data,
};
img_array.push(oneImg);
});
art_obj.img_array = [...img_array];
art_obj = JSON.stringify(art_obj);
//assemble images
let url = `${GLOBAL.BASE_URL}/api/artworks/new`;
await helper.getAPI(url, _result, "POST", art_obj); //<<==#1. send artwork and image record to backend server
//save image to cloud storage
var storageAccessInfo = await helper.getStorageAccessInfo(stateVal.storageAccessInfo);
if (storageAccessInfo && storageAccessInfo !== "upToDate")
//update the context value
stateVal.updateStorageAccessInfo(storageAccessInfo);
//
let bucket_name = "oss-hz-1"; //<<<
const configuration = {
maxRetryCount: 3,
timeoutIntervalForRequest: 30,
timeoutIntervalForResource: 24 * 60 * 60
};
const STSConfig = {
AccessKeyId:accessInfo.accessKeyId,
SecretKeyId:accessInfo.accessKeySecret,
SecurityToken:accessInfo.securityToken
}
const endPoint = 'oss-cn-hangzhou.aliyuncs.com'; //<<<
const last_5_cell_number = _myself.cell.substring(myself.cell.length - 5);
let filePath, objkey;
img_array.forEach(item => {
console.log("init sts");
AliyunOSS.initWithSecurityToken(STSConfig.SecurityToken,STSConfig.AccessKeyId,STSConfig.SecretKeyId,endPoint,configuration)
//console.log("before upload", AliyunOSS);
objkey = `${last_5_cell_number}/${item.fileName}`; //virtual subdir and file name
filePath = item.path;
AliyunOSS.asyncUpload(bucket_name, objkey, filePath).then( (res) => { //<<==#2 send images to cloud storage with callback. But no action required after success.
console.log("Success : ", res) //<<==not really necessary to have console output
}).catch((error)=>{
console.log(error)
})
})
} catch(err) {
console.log(err);
return false;
};
};
The concern with the code above is that those 2 async calls may take long time to finish while user may be waiting for too long. After clicking saving button, user may just want to move to next page on user interface and leaves those everything behind. Is there a way to do so? is removing await (#1) and callback (#2) able to do that?
if you want to do both tasks in the background, then you can't use await. I see that you are using await on sending the images to the backend, so remove that and use .then().catch(); you don't need to remove the callback on #2.
If you need to make sure #1 finishes before doing #2, then you will need to move the code for #2 intp #1's promise resolving code (inside the .then()).
Now, for catching error. You will need some sort of error handling that alerts the user that an error had occurred and the user should trigger another upload. One thing you can do is a red banner. I'm sure there are packages out there that can do that for you.

How to refresh v-data-table after REST API Patch call?

I have a data table in Vuetify that is populated via a REST get request, using a function "getData" that is called when the app is mounted. The <td>'s in the table have buttons that the user can hit to "lock" the period (the row/column intersection).
When they hit the button, they get a popup confirmation dialog. When they hit "OK", there is a save method called to write the current date back to the db via a REST PATCH request (see below).
My problem is, the grid is not updating with the results of the patch request. I have to manually refresh the page to see the result. What is the common pattern here? Should i pull down the data again via getData to refresh the table? Should i update the array that the data-table sits on directly?
getData method:
getData() {
var self = this;
return axios
.get("http://127.0.0.1:5000/api/estimatefinal/periods?dataset=capital")
.then(function(response) {
self.periods = response.data;
})
.catch(function(error) {
alert(error);
});
},
Save method:
save(item) {
var self = this;
axios
.patch("http://localhost:5000/api/estimatefinal/period/" + self.id, {
date: moment(self.selected_date, "YYYY-MM-DD").format(
"YYYY-MM-DDTH:m:s"
)
})
.then(function() {
this.getData(); // ????
})
.catch(function(error) {
alert(error)
});
this.getData(); // ????
this.close();
}
If your PATCH changes only one row in DB, means has visually effect on only one row on your v-data-table, then you can change the data locally when you get "success" response from back-end.
If, in other hand, your PATCH changes many other things in DB (also in v-data-table) your best option is probably to getData() after you get PATCH response.
Point is to keep that same "picture" of values in DB and on screen v-data-table.

Current user doesn't persist when reloading an app (Ionic2 + Parse Server)

I'm currently working on Ionic 2 app with Parse Server backend.
I implemented signed up process. No problems here, everything works as expected: new account is created, user is logged in after sign up and current user exists.
Now I want to use current user and bypass sign up/login page next time user opens the app (if the user is already logged in ). The Parse documentation clearly states:
“It would be bothersome if the user had to log in every time they
open your app. You can avoid this by using the cached
current Parse.User object. Whenever you use any signup or login
methods, the user is cached in localStorage.”
In my case, however, I can't manage to make it work. I create current user according to Parse documentation during initialization process of the app:
var currentUser = Parse.User.current();
if (currentUser) {
// do stuff with the user
} else {
// show the signup or login page
}
Every time I open the app after successful sign up the current user is NULL.
Any ideas?
I kinda understand what's going on, but still don't understand why.
During signup or login Parse is supposed to save current user to local storage, but if local storage is not available for some reason, it saves it to memory map. And this is what happens in my case: Parse always saves current user to memory map, which is, of cause, temporary storage. Hence, every time I reload the app, Parse memory map is empty. I don't understand why in my environment Parse decides that local storage is unavailable. I couldn't find in the code where this decision is made. It seems to me that memory map is default (which is probably not true). Could it be that local storage functionality is not implemented yet in the open source version of Parse? Or does it have something to do with Ionic2 implementation?
Is there anybody out there from Parse team who is familiar with this part of Parse code?
Thanks.
