Clear terminal screen but keep output history.
While working on friendly-errors-webpack-plugin to improve it for Next.js, I needed to clear the terminal screen without overriding previous output. Using ANSI escapes works for clearing the screen, but it will also override the output that's visible at that moment. So I created this simple solution to clear the screen but keep the history
npm install --save brighten
const brighten = require('brighten')
// clear screen when process is a TTY
if(process.stdout.isTTY) {
brighten()
}
