browserless
|
|
===========
|
|
|
|
[Browserless][1] makes it easy to run your puppeteer scripts in an optimized
|
|
way. It takes care of all the binaries and managing of Chrome so you don't have
|
|
to.
|
|
|
|
## docker-compose.yml
|
|
|
|
```yaml
|
|
browserless:
|
|
image: browserless/chrome:1-chrome-stable
|
|
ports:
|
|
- "3000:3000"
|
|
environment:
|
|
- DEBUG=browserless/chrome
|
|
- MAX_CONCURRENT_SESSIONS=10
|
|
- CONNECTION_TIMEOUT=600000
|
|
- MAX_QUEUE_LENGTH=10
|
|
- ENABLE_CORS=true
|
|
- CHROME_REFRESH_TIME=3600000
|
|
shm_size: 2gb
|
|
restart: always
|
|
```
|
|
|
|
## screenshot.js
|
|
|
|
```javascript
|
|
'use strict';
|
|
|
|
const puppeteer = require('puppeteer');
|
|
|
|
(async() => {
|
|
const browser = await puppeteer.connect({browserWSEndpoint: 'ws://localhost:3000'});
|
|
const page = await browser.newPage();
|
|
await page.goto('https://www.google.com/', {waitUntil: 'networkidle2'});
|
|
await page.screenshot({path: 'google.png', fullPage: true});
|
|
await browser.close();
|
|
})();
|
|
```
|
|
|
|
