React Native Expo Push notification for specific user - react-native

Expo allows you to send notification by device id which is ambiguous and not great for my use case, how can i send notification that only specific user will receive? for example can i pass user id or username besides device id?
this is the body request body:
{
to: pushToken, // user id or topic?
body: 'test notification',
data: { withSome: 'data' }
}

You have to create a db table where you'll record user_id / username & device_token in order to be able to send notification to a user by his user_id or username.

From attribute inside node mailer message not working always keep sending mail through default account which is used for creating account

let message={
from:email,
to:emails,
text:'Please join the meeting',
subject:`You are Invited for ${meetingName}`,
html:mail
}
Above is my message object the from attribute is not working. I want to send email from logged in user to the user given by him , but node mailer uses the email (my email which is configured at auth) it must use email given in from tag.
const config={
service:'gmail',
auth: {
user:"xx#gmail.com",
pass: ""
},
port:465,
host:'smtp.gmail.com'
}
always uses xx#gmail.com instead of logged in user

How to Handle push notification when sent to multiple device but some them are failed

I want to send fcm push notifications to android and ios app. I am using this code to send
let message = {
registration_ids: firebaseId, // this is the array of tokens
collapse_key: 'something',
data: {
type: data.type,
title: data.title,
body : data.body,
notificationId: something
},
};
fcm.send(message, (err, response) => {
if (err) {
console.log(err);
resolve(false);
} else {
console.log("Notification Android Sent Successfully");
console.log(response);
}
});
Now what I want if some notifications are failed then I want to send them SMS. but I got a response like this form the fcm server in case of success or failure.
Notification Android Sent Successfully
{"multicast_id":7535512435227354255,"success":2,"failure":1,"canonical_ids":0,"results":[{"message_id":"0:1610622370449056%d0bd483c86f03759"},{"message_id":"0:1610622370449058%d0bd483c86f03759"},{"error":"InvalidRegistration"}]}
now how will I know which device did not get the notification as we can see there 1 failure from 3 device
so i can send SMS to that device
The results in the response you get contains the result for each token, in the same order in which you specified them,
So in your example, the message was successfully sent to the first two tokens, while the third token was unknown. You'll want to remove that last token from your database to prevent trying to send messages to it in the future.

Cognito unable to signup users that have unconfirmed status already

A Cognito User Pool is configured for the users to use their "email address" to sign up and sign in.
If a user signs up with the email of someone else then that email will get stuck in UNCONFIRMED state and the owner will not be able to use it appropriately.
Having said that let me provide an example with the following scenario:
User signs in with an email address the user doesn't own, let's say it is someone#mail.com. In this step (registration form) some more data is sent like organization name, and user full name.
Verification code is sent to the email
Now the user that owns someone#email.com wants to create an account (maybe some days in the future), so he goes and fills the registration form but an error is thrown by cognito {"__type":"UsernameExistsException","message":"An account with the given email already exists."}
Thinks to consider:
* If the email already exists but is in unconfirmed state then provide the user the option to resend the link. This option is not optimal because additional data might be already in the user profile as the 1st step exemplifies.
* A custom lambda can be done to delete the unconfirmed user before signup or as a maintenance process every day, but I am not sure if this is the best approach.
There is also this configuration under Policies in cognito consol: "How quickly should user accounts created by administrators expire if not used?", but as he name implies this setting will only apply to users if they are invited by admins.
Is there a proper solution for this predicament?
Amazon Cognito has provided pre-signup triggers for these functionality and auto signup also.Your thought is the same way as i have implemented that according to the cognito documentations.
Here I am using the amplify/cli which is the toolchain for my development purpose hence the lambda function used in the trigger is as below:
`
"use strict";
console.log("Loading function");
var AWS = require("aws-sdk"),
uuid = require("uuid");
var cognitoIdentityServiceProvider = new AWS.CognitoIdentityServiceProvider();
exports.handler = (event, context, callback) => {
const modifiedEvent = event;
// check that we're acting on the right trigger
if (event.triggerSource === "PreSignUp_SignUp") {
var params = {
UserPoolId: event.userPoolId,
Username: event.userName
};
cognitoIdentityServiceProvider.adminGetUser(params, function(err, data) {
if (err) {
console.log(err, err.stack);
} // an error occurred
else {
console.log("cognito service", data);
if (data.UserStatus == "UNCONFIRMED") {
cognitoIdentityServiceProvider.adminDeleteUser(params, function(
err,
data
) {
if (err) console.log(err, err.stack);
// an error occurred
else console.log("Unconfirmed user delete successful ");
// successful response
});
}
// successful response
}
});
return;
}
// Throw an error if invoked from the wrong trigger
callback('Misconfigured Cognito Trigger '+ event.triggerSource);
};
`
this will actually check and delete if the status is UNCONFIRMED using the aws-sdk methods adminGetUser and adminDeleteUser
hope this will help ;)
I got around this by setting ForceAliasCreation=True. This would allow the real email owner to confirm their account. The draw back is that you end up with 2 users. One CONFIRMED user and another UNCONFIRMED user.
To clean this up, I have a lambda function that calls list-users with filter for unconfirmed user and delete the accounts which were created before a certain period. This function is triggered daily by CloudWatch.
change to confirm from unconfirm:
aws cognito-idp admin-confirm-sign-up \
--user-pool-id %aws_user_pools_web_client_id% \
--username %email_address%

api Telegram webhook : how can delete new_chat_participant message

I created a bot via webhook method of api telegram and It's okay and working.
but I want know how can delete any new_chat_participant messages before sending message by members.
You know that telegram don't send request to your hook url until have not any message with members !!!!!!!
I need just message_id for example when a member add an another to supper group.
Set /setprivacy to disable in #BotFather to receive the whole actions and messages from your group. (In order to delete these messages, the bot must has access to messages in the group, needs to be administrator).
When new member has been added to group, you will receive a json in your webhook something like this:
{ update_id: 123123123,
message:
{ message_id: 2599, // Pay attention to this message id
from: {
...
},
chat: {
id: -987372183 // This is your group's id
...
},
date: 1582378239,
new_chat_participant: { // Field when new member is added to group
}
...
}
Now you need to send a post request to Telegram to delete this message (action). The request is:
request.post("https://api.telegram.org/botYOUR_BOT_TOKEN/deleteMessage?chat_id=GROUP_ID&message_id=MESSAGE_ID_RECEIVED", ... )
Hope this helps.

I'am actually using a customDB and here is my getUser script, but I don't know what to change, could you help me?
Thank you!
function getByEmail (email, callback) {
mongo('mongodb://user:pass#dsXXXX.mlab.com:XXXX/base', function (db) {
var users = db.collection('user');
users.findOne({ email: email }, function (err, user) {
if (err) return callback(new Error("my error message"));
if (!user) return callback(null);
var profile = {
user_id: user._id,
nickname: user.username,
email: user.email,
};
callback(null, profile);
});
});
}
Ok, just re-read your question - where you state "my users have to enter their password and are also stored in mongodb." - are you referring to your own Mongo DB? Are you using an Auth0 Custom DB Connection? Confusingly, Auth0 also uses MongoDB for its own DB storage, hence the clarification. If you are using a Custom DB connection to your own DB, then this may be a misconfiguration of one of your Custom DB Scripts. If using Custom DB Script, please double-check the implementation of your GetUser.js script.
In the event, you are using an Auth0 DB (not a custom DB) then definitely check with Auth0 support team (as per comment and your reply above).
