The minimum setup necessary to make puppeteer return the response body of a request

gulpfile.js

const gulp = require('gulp')
const puppeteer = require('puppeteer')

const err = (err) => console.log(err)

gulp.task('puppeteer', async (done) => {
    const browser = await puppeteer.launch()
    const page = await browser.newPage()
    await page.goto('http://localhost/puppeteer/build/')
        .then( async (response) => {
            await response.text()
                .then( text => console.log(text) )
                .catch(err)
        })
        .catch(err)
    done()
})

gulp.on('stop', () => {
      process.nextTick( () => process.exit(0) )
})
