How to get a link from from feed-watcher updates - node.js

Question

I'm trying to build medium integration so when I new post arrives on medium, bot will then send the post link to the discord channel. The Problem is I don't know how to take data from the feed response so I can use it in the message. Once I receive the response from the feed, it looks like this.

I tried to parse response so I can take the link from the response like this.
const link = JSON.parse(entry)
console.log('FEED Call response:', link["link"]);
client.on('ready', () => {
watcher.on('new entries', function (entries) {
entries.forEach(function (entry) {
const link = JSON.parse(entry)
console.log('FEED Call response:', link["link"]);
console.log(entry)
})
})
watcher
.start()
.then(function (entries) {
console.log(entries)
})
.catch(function(error) {
console.error(error)
})
})
Any idea how can I receive the data I want from the response so I can use it in the message?
Error: SyntaxError: Unexpected token o in JSON at position 1
I tried to use this, however I don't know how to get the link from the response.
const link = JSON.stringify(entries)
console.log('FEED Call response:', link);
console.log(`Link:`, link[0].link)
Reponse is Link: [Function: link]

Answer 1

You do not have to use JSON.parse at all! The received data is already the object you want. JSON.parse automatically sets its first argument as a string, and that makes it change to the following string:
"[object Object]"
JSON allows the [ but not the o without a quotation mark. The following code will work just fine.
entries.forEach((entry) => {
console.log('FEED Call response:', entry);
console.log(entry[0].link)
})

I found a solution! First we need to stringify data and then parse them to JSON, right after i can pick link from the first array.
const stringifylink = JSON.stringify(entry)
const link = JSON.parse(stringifylink)
console.log('FEED Call response:', link);
console.log('Link:', link[0].link)
