Pappet is a command-line tool to crawl websites using puppeteer. It allows you to crawl multiple pages in parallel and recursively. Take screenshots or create PDFs in seconds.

Examples

Pappet allows you to write most of the options in a long and short form. I will use the shorter syntax here for convenience.

Take a screenshot (-s, --screenshot)

 

pappet -s https://example.com

You can also specify the width and height of the viewport.

 

pappet -s -w 800 -h 600 https://example.com

Take a screenshot of the full scrollable page. By specifying the option -f or --full-page.

 

pappet -sf https://example.com

Take a PDF (-p, --pdf)

 

pappet -p https://example.com

Crawl a website recursively and take screenshots (-r, --recursive)

 

pappet -sr https://example.com

When crawling websites recursively you should specify a maximum depth (default 1) for not crawling to long. You can do that by using the -l or --level option.

 

pappet -srl2 https://example.com

Crawl multiple pages at once

You can specify a infinite number of URLs to crawl.

 

pappet -rs https://example.com https://example.com

When doing this it's recommended to use the option -t or --tabs. This will set the maximum number of pages used by puppeteer (default 2). The more pages you have the faster it will be. Be careful by specifying this option. Some websites may block you, for sending to many requests at once.

 

pappet -rst4 https://example.com

Disable javascript and take a screenshot

 

pappet -sf --disable-js https://example.com

Only visit pages with same origin

This will only follow links of the same origin (example.com).

 

pappet -rs --same-origin https://example.com

Only follow relative links

 

pappet -rsL https://example.com
