njtool

Tool for nature.com users

njtool provides useful commands to operate on www.nature.com with Puppeteer.

How to use

A command below fetches PDF files of articles in "Nature Volume 555 Issue 7694", and saves them into /journals/nature/555/7694:

$ njtool scrape journal nature:555:7694 | \
    njtool download -u your@email.address -p your_password -o /journals

You can use the following environment variables instead of specified options in download subcommand:

• NJTOOL_NATURE_USERNAME
• NJTOOL_NATURE_PASSWORD
• NJTOOL_NATURE_OUTDIR

$ cat .envrc
export NJTOOL_NATURE_USERNAME="your@email.address"
export NJTOOL_NATURE_PASSWORD="your_password"
export NJTOOL_NATURE_OUTDIR="/journals"

$ njtool scrape journal nature:555:7694 | njtool download

Downloading multiple journals are supported:

$ njtool scrape journal nature:555:7695 nature:555:7696 | \
    njtool download

Downloading journals of specific volumes:

$ njtool scrape volume --only-ids nature:555 nature:556 | \
    njtool scrape journal | njtool download

At this moment, njtool supports only Nature. I have no plan to support other journals. Because I have no plan to subscribe others.

njtool works fine on macOS, Linux and Windows.

It's recommended for macOS users to use caffeinate in order to prevent the system from sleeping when you run njtool download which typically takes a long time.

$ njtool scrape journal nature:555:7697 | caffeinate -i njtool download ...

Linux users may need to run commands with the --no-sandbox option.

See help for details of each command:

$ njtool help
