NodeJS template literal with async map - node.js

I'm trying to generate an HTML content using template literal because I need to loop through an array. It is not returning the map content to the template literal.
const htmlData = `
<html>
... // Some content here
<table class="table table-bordered" style="width: 800px;" align="center">
<thead class="thead-light">
<tr>
<th>Company</th>
<th>Bill Date</th>
<th>Billing Days</th>
<th>Total Units</th>
</tr>
</thead>
<tbody>
${customers.map( async (customer) => {
let units = 0;
const companyDate = new Date(customer.CompanyStartDate);
const billDate = new Date(today.getFullYear(), today.getMonth(), companyDate.getDate());
const numDays = (today.getTime() - billDate.getTime()) / (1000 * 3600 * 24);
const pData = await property.getPropTotalUnitsByCompany(customer.CompanyID);
return (
`
<tr>
<td>
${pData.map(async (propData) => {
units += propData.TotalUnits;
return (
`
<div class="row">
<div class="col-sm-12" align="right">
Property: ${propData.PropertyName} Total Units: ${propData.TotalUnits}
</div>
</div>
`
);
})}
</td>
<td>${myFunctions.formatDisplayDate(billDate)}</td>
<td>${numDays}</td>
<td>${units}</td>
</tr>
`
);
})}
</tbody>
</table>
... // More content here
</html>
`;
It returns [object Promise] inside my . Here is where I have the .map(). Can't I use map in template literals?
Thank you

Map array dont show in table

I need map a array inside my page, and show the result in a table, but the content don't show up when I compiled the page.
Can anyone help me?
When I print in console the content of a var, this is here. But the info don't show up in the page
import Layout, { siteTitle } from '../components/layout'
const fetch = require('node-fetch');
export default function Home({ devices }) {
return (
<Layout >
{devices.map((device) => (
<table>
<thead>
<th>
{device.localname} / {device.localIP}
</th>
</thead>
{console.log('1')}
<tbody>
<tr>
<td>
{device.IPaddress[0][3].value} // I put this to test, and this works fine
</td>
</tr>
{device.IPaddress.map((port) =>{
<tr>
<td>
{console.log(port[3].value), port[3].value} // here I need to work, I want to put all results of port in a TD tag, the console.log shows up the info, but the page not.
</td>
</tr>
})}
</tbody>
</table>
))}
</Layout >
)
}
export async function getStaticProps() {
const res = await fetch('http://localhost:3000')
const devices = await res.json()
return {
props: {
devices
}
}
}
As commented by #evgenifotia, change the ( for { inside the second array map works fine.
here the final function:
export default function Home({ devices }) {
return (
<Layout >
{devices.map((device) => (
<table>
{console.log('1')}
<tbody>
<tr>
<th>
{device.localname} / {device.localIP}
</th>
</tr>
{device.IPaddress.map(port =>(
<tr>
<td>
{console.log(port[3].value), port[3].value}
</td>
</tr>
))}
</tbody>
</table>
))}
</Layout >
)
}

Loop Inside node.js module

Here is my module.
module.exports = function (requestUser) {
let content = `
<div id="cpl">
<table id="currentpatientslists">
</table>
</div>
<div id="rp">
<h1>Requested Patients</h1>
</div>
<hr>
<div id="note" >Currently no patients</div>
<div id="rpl">
<table id="requestedpatientslists">
<tr>
<td width="30%"></td>
<td width="30%" class="right"><button>Accept</button></td>
<td width="30%" class="left"><button>Reject</button></td>
</tr>
</table>
</div>`;
return render(content);
}
In the requestedpatientslists table , I want to loop the data in the table row coming from requestUser which is an array. I want to loop it until requestUser.length. How can I do that?
You just need to loop over the users and create the rows for them first
module.exports = function(requestUser) {
// I'm guessing that the user has normal properties like name, etc?
const tableRows = requestUser.map(
user => `
<tr>
<td width="30%">${user.name}</td>
<td width="30%" class="right"><button>Accept</button></td>
<td width="30%" class="left"><button>Reject</button></td>
</tr>
`,
);
const content = `
<div id="cpl">
<table id="currentpatientslists">
</table>
</div>
<div id="rp">
<h1>Requested Patients</h1>
</div>
<hr>
<div id="note" >Currently no patients</div>
<div id="rpl">
<table id="requestedpatientslists">
${tableRows.join('\n')}
</table>
</div>`;
return render(content);
};

How can i render data on change?

I'm trying to build a project in nodejs as server and firebase as my realtime db and having some problems with forwarding the data to my html.
I getting the error:
Cannot set headers after they are sent to the client
on change
I'm trying to pass the updated arr to html but can't find a way to do that.
server.js:
const locksRef = await firebase.firebase.database().ref('locks')
let arr = []
//get list of locks
const t = locksRef.on('value', (data) => {
tempResult3 = data.val()
result3 = []
const numOfKeys = Object.keys(tempResult3)
numOfKeys.forEach((x) => {
result3.push(tempResult3[x])
})
result3.forEach((k) => {
myLocks.forEach((my) => {
if (k.id == my) {
arr.push(k)
}
})
})
res.render('ListOfLocks', { arr })
})
html
<body>
<h1>ListOfHouses</h1>
<table border="1px solid black">
<thead>
<th>Name And Address</th>
</thead>
<tbody>
{{#each arr}}
<tr>
<td id="data"> {{name}} - {{address}}</td>
<td>
<form action="/seekKeys" method="post"><button name="{{locks}}" type="submit">LookForKey</button>
</form>
</td>
</tr>
{{/each}}
</tbody>
</table>
</body>

Loading a Partial view which has a complex model of many sub models into a jquery ui tab

I get an error when loading a particular view via an Html.action call to an action and Controller, into a jquery Tab.
The other View is loaded successfully via an HTML.Partial call.
How do I get this other particular partial loaded please.
The tab where the error happens is tab4.
The commented out HTML.Partial call works to a point but when it loads that Partial (User), which has multiple models in it's containing model,..those other models are null and it's iteration over them crashes.
(That partial is beneath the first block of code.)
If I try load it from an action Call, then
the JQuery function ("$#tabs").tabs crashes with ".tabs" is undefined
TIA

Check your console what error you got.
and also change this in tab4
#{
#Html.Partial("List", new Catalyst.Mvc.IdentityUserPersonViewModel())
