I am trying to use pupetteer-core but when I run my code.
const puppeteer = require('puppeteer-core');
module.exports= run = () => {
const url = '
const browser = puppeteer.launch();
const page = browser.newPage().then(function(page){
page.goto(url)
return browser
};
run().catch(console.error.bind(console))
I get this error
TypeError: browser.newPage is not a function

The problem in your code is that puppeteer works with Promises, meaning that most functions will return a Promise instead of the value directly. This means that you ether have to use then function or await statements to get the value.
Code sample
module.exports = run = async () => {
const url = '
const browser = await puppeteer.launch();
const page = await browser.newPage();
await page.goto(url);
return browser;
};
Note that the function is marked as async now, making it implicitly returning a Promise. That means to wait for the run() function to finish, you would have to call it from within another async function like this:
(async () => {
const browser = await run();
})();
