How to dynamically construct json in node JS

Question

I would like to construct a dynamic json and do a post call. I am using ${data.list.name} to get the value from an object but it is not working. Is there a way to do this?

function callTeams (data) {
 fetch(WEBHOOK, {
 'method': 'POST',
 'headers': { 'Content-Type': 'application/json' },
 'body': JSON.stringify({
 "@type": "MessageCard",
 "@context": "http://schema.org/extensions",
 "themeColor": "0076D7",
 "sections": [{
 "activityTitle": "${data.list.name} is valid",
 "activityImage": "https://teamsnodesample.azurewebsites.net/static/img/image5.png",
 "facts": [ {
 "name": "Key",
 "value": "${data.list.name}"
 }],
 "markdown": true
 }],
 "potentialAction": [ {
 "@type": "OpenUri",
 "name": "Submit",
 "targets": [{
 "os": "default",
 "uri": "https://learn.microsoft.com/outlook/actionable-messages"
 }]
 }]
})
 })
}

• Lawrence Cherone: use basic string concatenation or template literals
• Porok12: why you wrapping name with "${...}"? Past value directly if it is string or use ``
• ezhil: I tried with both double quote and single quote but it is not working.

Answer 1

Use template literals. Replace things like

{
 "activityTitle": "${data.list.name} is valid"
}

with

{
 "activityTitle": `${data.list.name} is valid`
}

In other words, use backticks (`)

• ezhil: Thanks for your response. tried with both double quote and single quote but it is not working. I got response like $ is valid.
• Yanick Rochon: It's neither double quote or single quote, it's the ` character
• ezhil: ohh yeah. it worked with ` character. Thanks
