linkedin-post-analytics-example.mjs

// paste this file on a empty directory
// npm i axios

// You should go to your browser on Cookie session and get JSESSIONID and li_at from Linkedin Section
const JSESSIONID = 'YOUR JSESSIONID'
const liAT = 'YOUR li_at'

import axios from 'axios'

const headers = {
    "user-agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.181 Safari/537.36",
    Cookie: `JSESSIONID=${JSESSIONID}; li_at=${liAT};`,
    "csrf-token": `${JSESSIONID}`
};


function getPostId(link) {
    const postId = link.match(/activity-(?<postId>\d+)/)?.groups?.postId
    return postId
}

async function getLinkedinViews(link) {
    const postId = getPostId(link)
    if(!postId) {
        console.error(`postId not found!`, link)
        return;
    }

    const url = `https://www.linkedin.com/voyager/api/feed/updatesV2?commentsCount=0&likesCount=0&q=backendUrnOrNss&urnOrNss=urn:li:activity:${postId}`
    const { data: file } = await axios.get(url, {
        headers
    })
    
    // just to save time, I got the property using regex :)
    const views = JSON.stringify(file).match(/"numViews":(?<views>\d+)/)?.groups?.views

    return views
}
const postURL = 'https://www.linkedin.com/posts/erickwendel_dica-de-ouro-para-entrevistas-em-ingl%C3%AAs-activity-6764509683727265792-l7v1'

look that the file must be named as .mjs not .js as it's an ecmascript module.
