get-puppeteer-browser
Get a singleton puppeteer browser instance.
Creating a puppeteer browser instance is very slow. It is usually better to reuse than to create each time.
Install
npm i get-puppeteer-browser
Example
const createBrowserGetter = require('get-puppeteer-browser')
const puppeteer = require('puppeteer')
const getBrowser = createBrowserGetter(puppeteer, {headless: true, devtools: true});
(async () => {
const b1 = await getBrowser()
const b2 = await getBrowser()
console.log(b1 === b2) // => true
await b1.close() // Not yet closed
await b2.close() // Close now.
})()
API
createBrowserGetter(puppeteer, launchOptions)
Create a getBrowser
function.
Debounce option
Debounce without closing immediately.
const getBrowser = createBrowserGetter(puppeteer, {debounce: 1000});
(async () => {
const b1 = await getBrowser()
b1.close()
delay(900).then(async () => {
const b2 = await getBrowser()
console.log(b1 === b2) // => true
b2.close()
delay(1000).then(async () => {
const b3 = await getBrowser()
console.log(b2 === b3) // => false
})
})
})()
