POC to download instagram images without the API

instaServer.js

const express = require('express')
const axios = require('axios');
const app = express()
const port = 3000

async function instagramPhotos (theProfile) {
    // It will contain our photos' links
    const res = []
    
    try {
        const userInfoSource = await axios.get(`https://www.instagram.com/${theProfile}/`)

        // userInfoSource.data contains the HTML from Axios
        const jsonObject = userInfoSource.data.match(/<script type="text\/javascript">window\._sharedData = (.*)<\/script>/)[1].slice(0, -1)

        const userInfo = JSON.parse(jsonObject)
        // Retrieve only the first 10 results
        const mediaArray = userInfo.entry_data.ProfilePage[0].graphql.user.edge_owner_to_timeline_media.edges.splice(0, 10)
        for (let media of mediaArray) {
            const node = media.node
            
            // Process only if is an image
            if ((node.__typename && node.__typename !== 'GraphImage')) {
                continue
            }

            // Push the thumbnail src in the array
            res.push(node.thumbnail_src)
        }
    } catch (e) {
        console.error('Unable to retrieve photos. Reason: ' + e.toString())
    }
    
    return res
}

app.get('/insta/:profile', async function(req, res) {
	console.log(`fecthing profile [${req.params.profile}]`);
	let images = await instagramPhotos(req.params.profile);
	console.log(`found [${new Array(images).length}] images`);
    res.send(JSON.stringify(images));
});

app.listen(port, () => {
  console.log(`Example app listening at http://localhost:${port}`)
})
