Opening local HTML file using Puppeteer

Question

Is it possible to open a local HTML file with headless Chrome using Puppeteer (without a web server)? I could only get it to work against a local server.

I found setContent() and goto() in the Puppeteer API documentation, but:

1. page.goto: did not work with a local file or file://.
2. page.setContent: is for an HTML string

Answer 1

If file is on local, using setContent will be better than goto

var contentHtml = fs.readFileSync('C:/Users/compoundeye/test.html', 'utf8'); await page.setContent(contentHtml); 

You can check performance between setContent and goto at here

Answer 2

I just did a test locally (you can see I did this on windows) and puppeteer happily opened my local html file using page.goto and a full file url, and saved it as a pdf:

'use strict';  const puppeteer = require('puppeteer');     (async() => {     const browser = await puppeteer.launch(); const page = await browser.newPage();     await page.goto('file://C:/Users/compoundeye/test.html');     await page.pdf({   path: 'test.pdf',   format: 'A4',   margin: {         top: "20px",         left: "20px",         right: "20px",         bottom: "20px"   }     });     await browser.close();     })(); 

If you need to use a relative path might want to look at this question about the use of relative file paths: File Uri Scheme and Relative Files
