the json is override when i use fs.writefilesync

i wanted to add something to my son file but when I try to add it just override my son file can someone help me with this
const fs = require('fs')
const chalk = require('chalk')
const getNotes = function(){
return 'Your notes....'
}
// add note function
const addNote = function (title, body) {
const notes = loadNotes()
const duplicateNotes = notes.filter(function (note) {
return note.title === title
})
if (duplicateNotes.length === 0) {
notes.push({
title: title,
body: body
})
saveNotes(notes)
console.log(chalk.green.inverse('New note added!'))
} else {
console.log(chalk.red.inverse('Note title taken!'))
}
}
const saveNotes = function(notes){
const dataJSON = JSON.stringify(notes)
fs.writeFileSync('notes.json', dataJSON)
}
const loadNotes = function(){
try{
const dataBuffer = fs.readFileSync(notes.json)
const dataJSON = dataBuffer.toString();
return JSON.parse(dataJSON)
}catch (e){
return []
}
}
module.exports = {
getNotes: getNotes,
addNote: addNote,
}
when I run node app.js add --title="list" --body="apple" and then i add another different title and body it just override the --title="list" --body="apple why is that happening ?

It seems you just forgot the quotes:
const dataBuffer = fs.readFileSync(notes.json)
should be
const dataBuffer = fs.readFileSync('notes.json')

How to make api endpoint target user's localhost when deployed to Heroku

I have this api which works fine when running locally. But, once it is deployed to Heroku i get a error 503 which is because it tries to target localhost on Heroku's server and not the user's localhost. Is there a way to make this target the user's localhost instead?
The frontend is React. Here's the code in React that fetches this api every 5sec.
axiosFunc = () => {
const { user } = this.props.auth;
console.log(user);
axios.get(`api/avaya/${user.id}`).then((res) => console.log(res));
};
timer = (time) => {
const date = new Date(time);
return `${date.getHours()}:${date.getMinutes()}:${date.getSeconds()}`;
};
componentDidMount() {
this.axiosFunc();
this.interval = setInterval(this.axiosFunc, 5000);
}
componentWillUnmount() {
clearInterval(this.interval);
}
and this is the API on the backend with express
const router = require("express").Router();
const xml2js = require("xml2js");
const Avaya = require("../../models/Avaya");
const User = require("../../models/User");
router.route("/:id").get(async (req, res) => {
const user = await User.findById(req.params.id);
const axios = require("axios");
axios({
method: "post",
baseURL: `http://127.0.0.1:60000/onexagent/api/registerclient?name=${user.username}`,
timeout: 2000,
})
.then((reg) => {
xml2js
.parseStringPromise(reg.data, { mergeAttrs: true })
.then((result) => {
if (result.RegisterClientResponse.ResponseCode[0] === "0") {
const clientId = result.RegisterClientResponse.ClientId[0];
user.avayaClientId = clientId;
user.save();
}
const clientId = user.avayaClientId;
axios({
method: "post",
url: `http://127.0.0.1:60000/onexagent/api/nextnotification?clientid=${clientId}`,
}).then((notification) => {
xml2js
.parseStringPromise(notification.data, { mergeAttrs: true })
.then((result) => {
const notifType = [];
const notifDetails = [];
for (let i in result.NextNotificationResponse) {
notifType.push(i);
}
const arranged = {
NotificationType: notifType[1],
ResponseCode:
result.NextNotificationResponse[notifType[0]][0],
};
for (let i in result.NextNotificationResponse[
notifType[1]
][0]) {
notifDetails.push(i);
}
for (let i = 0; i < notifDetails.length; i++) {
arranged[[notifDetails[i]][0]] =
result.NextNotificationResponse[notifType[1]][0][
notifDetails[i]
][0];
}
for (let i in arranged) {
if ("Outbound" in arranged) {
arranged.CallType = "Outbound";
} else if ("Inbound" in arranged)
arranged.CallType = "Inbound";
else {
arranged.CallType = " ";
}
}
if (
arranged.NotificationType === "VoiceInteractionCreated" ||
arranged.NotificationType === "VoiceInteractionMissed" ||
arranged.NotificationType === "VoiceInteractionTerminated"
) {
const newLogs = new Avaya({
notification: arranged,
});
newLogs.owner = user;
newLogs.save();
user.avayaNotifications.push(newLogs),
user
.save()
.then((logs) => res.json(logs))
.catch((err) => res.status(400).json("Error: " + err));
} else {
res.send("Nothing to record");
}
});
});
});
})
.catch((err) => res.status(503).json(err));
});
router.route("/history/:username").get(async (req, res) => {
const user = await User.findOne({ username: [`${req.params.username}`] });
Avaya.find({ owner: [`${await user.id}`] }).then((user) => res.json(user));
});
module.exports = router;
EDIT: I was able to fix thanks to #Molda
using fetch instead of axios doesn't result in cors error.
New frontend code
getLogs = async () => {

I really don't get the part of (requesting with Axios in API)
Is this a third party API ?
But I suggest you to use (.env) which is a file in your root folder contains the development config like base URLs, expire tokens, API keys ... etc
and when you upload to Heroku you have to make a (.env) in Heroku app and but your config
Let's take an example
in my development mode, my .env looks like
app_url = localhost:4000
port = 4000
db = development_api
db_username = root
db_password =
db_engine = mysql2
in my production mode, my .env looks like
app_url = http://appsomething.heroku.com
port = 80
db = production_api
db_username = root
db_password = 3210LDWAK#AALKQ
db_engine = mysql2
and read more about how to use .ENV

How do I send transactions and transfer TT on ThunderCore mainnet?

Without using ThunderCore Hub or any Web3 wallet which supports Thunder Token, how could I programmatically send transactions or transfer Thunder Tokens?

To send a transaction on Thundercore, set these fields in the transaction:
set chainId with from net_version() (eth.net.getId())
set nonce with the value of eth_getTransactionCount() (eth.getTransactionCount)
set gas price from eth_gasPrice() (getGasPrice)
set gas limit from eth_estimateGas (eth.estimateGas)
See the submitTx method in the following code:
transfer.js
const fs = require('fs');
const path = require('path');
const Accounts = require('web3-eth-accounts');
const Eth = require('web3-eth');
const Web3 = require('web3');
const BN = Web3.utils.BN;
const pretty = require('./pretty');
const erc20Abi = require('./ERC20.abi.json');
const web3Provider = () => {
return Eth.giveProvider || 'https://mainnet-rpc.thundercore.com';
}
const signTx = async (fromAccount, tx) => {
const signedTx = await fromAccount.signTransaction(tx)
return signedTx.rawTransaction // hex string
}
class ChainHelper {
constructor(eth, chainId, fromAccount) {
this.eth = eth;
this.chainId = chainId;
this.fromAccount = fromAccount;
this.fromAddress = fromAccount.address;
}
async submitTx(toAddress, value, txData) {
const eth = this.eth;
const promiseResults = await Promise.all([
eth.getTransactionCount(this.fromAccount.address),
eth.getGasPrice(),
]);
const nonce = promiseResults[0];
const gasPrice = promiseResults[1];
const fromAddress = this.fromAddress;
const tx = {
'gasLimit': 0,
'chainId': this.chainId,
'gasPrice': gasPrice,
'nonce': nonce,
'from': fromAddress,
'to': toAddress,
'value': value,
'data': txData,
}
const gasMultiple = new BN(1.0);
tx.gasLimit = '0x' + (new BN(await eth.estimateGas(tx))).mul(gasMultiple).toString(16);
console.log('tx:', pretty.format(tx));
const rawTxStr = await signTx(this.fromAccount, tx);
return eth.sendSignedTransaction(rawTxStr);
}
async transferToken (contractAddress, toAddress, value) {
const eth = this.eth;
const contractAbi = erc20Abi;
const contract = new eth.Contract(contractAbi, contractAddress);
const txData = contract.methods.transfer(toAddress, value).encodeABI();
return this.submitTx(contractAddress, 0, txData);
}
}
const create = async (privateKey) => {
const accounts = new Accounts();
if (!privateKey.startsWith('0x')) {
privateKey = '0x' + privateKey;
}
const account = accounts.privateKeyToAccount(privateKey);
const eth = new Eth(web3Provider());
const networkId = await eth.net.getId();
return new ChainHelper(eth, networkId, account);
}
const readKeys = () => {
const privateKeys = fs.readFileSync(path.join(__dirname, '..', '.private-keys'),
{encoding: 'ascii'}).split('\n').filter(x => x.length > 0);
return privateKeys;
}
module.exports = {
create: create,
readKeys: readKeys,
};
testTransfer.js
const fs = require('fs');
const path = require('path');
const ChainHelper = require('../src/transfer.js');
const toAddress = '0x6f0d809e0fa6650460324f26df239bde6c004ecf';
describe('transfer', () => {
it('transfer TT', async() => {
const privateKey = ChainHelper.readKeys()[0]
const c = await ChainHelper.create(privateKey);
c.submitTx(toAddress, 1, '');
});
it('tokenTransfer', async() => {
const privateKey = ChainHelper.readKeys()[0]
const c = await ChainHelper.create(privateKey);
/* Token.issue() */
const jsonBuf = fs.readFileSync(path.join(__dirname, '..', 'build', 'contracts', 'Token.json'));
const contractData = JSON.parse(jsonBuf);
const contractAbi = contractData['abi'];
const contractAddress = contractData['networks'][c.chainId]['address'];
const contract = new c.eth.Contract(contractAbi, contractAddress);
const toAddress = c.fromAddress;
const tokenAmount = 2;
let txData = contract.methods.issue(tokenAmount, c.fromAddress).encodeABI();
let r = await c.submitTx(toAddress, 0, txData);
console.log('Token.issue receipt:', r);
/* Token.transfer() */
r = await c.transferToken(contractAddress, toAddress, tokenAmount)
console.log('Token.transfer receipt:', r);
});
});
The code above targets the command line or server-side node.js, to send transactions from a browser replace signTx and eth.sendSignedTransaction with web3.eth.sendTransaction
The complete example is in the transfer branch of this field-support repo.

Copy a document into a new collection in firestore using cloud function

Path 1 - Match_Creator/cricket/matchList;
Path 2 - Match_Creator/cricket/completedMatchList;
I have a collection called matchList (Path 1) In which i am having a doc called c434108.
Now I want to move this doc(c434108) to Path 2;
/* eslint-disable promise/catch-or-return */
const functions = require("firebase-functions");
const admin = require("firebase-admin");
const { db } = require("./db/index");
const createCompletedMatchListDoc = (request, response) => {
completedMatchDocsData();
};
function completedMatchDocsData() {
createNewCompletedMatchDocs()
}
function getOldCompletedMatchDocs(){
var completedMatchesRef = db
.collection("Match_Creator")
.doc("cricket")
.collection("matchList");
var completedMatchDocData;
var completedMatchDataArr = [];
return new Promise(resolve => {
let query = completedMatchesRef
.where("status", "==", "live")
.get()
.then(snapshot => {
// eslint-disable-next-line promise/always-return
if (snapshot.empty) {
console.log("No matching documents.");
return;
}
snapshot.forEach(doc => {
completedMatchDocData = doc.data();
completedMatchDataArr.push(completedMatchDocData);
resolve(completedMatchDataArr);
});
console.log("sarang", completedMatchDataArr[2]);
})
.catch(err => {
console.log("Error getting documents", err);
});
});
}
const createNewCompletedMatchDocs = (async(change, context) => {
let completedMatchData = await getOldCompletedMatchDocs();
console.log('aman', completedMatchData[1]);
const newValue = change.after.data();
const previousValue = change.before.data();
const st1 =newValue.status;
const st2 = previousValue.status;
console.log('I am a log entry' + st1 + ' ' + st2);
var data = completedMatchData[0];
return db.collection('Match_Creator').doc('cricket').collection('completedMatchList').add(data)
.catch(error => {
console.log('Error writting document: ' + error);
return false;
});
})
module.exports = createCompletedMatchListDoc;
And After copy this doc(c434108) i want to delete this doc(c434108) from path 1.
And My index.js file is:
const functions = require("firebase-functions");
const admin = require("firebase-admin");
const storeMatchData = require("./liveScoring");
const createCompletedMatchListDoc = require("./completedMatchList");
var http = require("https");
module.exports = {
liveScoring: functions.https.onRequest(storeMatchData),
createCompletedMatchListDoc: functions.https.onRequest(
createCompletedMatchListDoc
)
};

I am able to solve my problem.
This is my completeMatchList.js file
/* eslint-disable promise/catch-or-return */
const functions = require("firebase-functions");
const admin = require("firebase-admin");
const { db } = require("./db/index");
const createCompletedMatchListDoc = (request, response) => {
completedMatchDocsData();
};
function completedMatchDocsData() {
setNewCompletedMatchDocs()
}
function getOldCompletedMatchDocs(){
var completedMatchesRef = db
.collection("Match_Creator")
.doc("cricket")
.collection("matchList");
var completedMatchDocData;
var completedMatchDataArr = [];
return new Promise(resolve => {
let query = completedMatchesRef
.where("status", "==", "live")
.get()
.then(snapshot => {
// eslint-disable-next-line promise/always-return
if (snapshot.empty) {
console.log("No matching documents.");
return;
}
snapshot.forEach(doc => {
// completedMatchDocData = doc.data();
completedMatchDocData = {
docId: "",
docData: ""
}
completedMatchDocData.docId = doc.id;
completedMatchDocData.docData = doc.data();
completedMatchDataArr.push(completedMatchDocData);
resolve(completedMatchDataArr); // Here i am getting the data and pushing it in array
});
console.log("sarang", completedMatchDataArr);
})
.catch(err => {
console.log("Error getting documents", err);
});
});
}
const setNewCompletedMatchDocs = (async () => {
let getCompletedMatchData = await getOldCompletedMatchDocs();
// console.log("balram", getCompletedMatchData[0].docId);
let newCompletedMatchDocRef = db.collection("Match_Creator").doc("cricket").collection("completedMatchList").doc(getCompletedMatchData[0].docId);
return newCompletedMatchDocRef.set(getCompletedMatchData[0].docData); //set/copy the data to new path.
})
This is my main index.js file
const functions = require("firebase-functions");
const admin = require("firebase-admin");
const storeMatchData = require("./liveScoring");
const createCompletedMatchListDoc = require("./completedMatchList");
const { db } = require("./db/index");
var http = require("https");
module.exports = {
liveScoring: functions.https.onRequest(storeMatchData),
createCompletedMatchListDoc: functions.https.onRequest(
createCompletedMatchListDoc
)
};
Now after copy document data to a new path i will delete the previous document. For deleting the document i have not written the function.

I'm not seeing anything that would allow you to move a document between collections(someone correct me if I'm wrong). You have to copy from the old collection to the new one and then remove the old one.
This is another post on StackOverflow that is running into this same issue and someone provided Java code on how to implement it.
EDIT: Updated link.
Hope this helps.

Trying to test if next function was called on router

i don't know if the questions is very clear, but probably looking at the code you'll understand.
i'm trying to see if the next() function was called on my router.
But everytime i use the debugger, i watch that the next i passed as a stub to my router don't get on my router as a stub, looks like it get lost on the way. If i extract the callback from the router and exports it separately, it works just fine. But i didn't want to separate things and export them.
