@bramus/caniuse-cli

Command line tool for “Can I Use …” and MDN Browser Compat Data

Features

• Instant, offline, results powered by caniuse-db, @mdn/browser-compat-data, and web-features.
• Displays color-coded Baseline status (Widely available, Newly available, or Limited availability).
• Collapses versions with the same level of support in the table, just like the “Can I Use …” website.
• Shows notes by number.
• Supports tab autocompletion in zsh, bash and fish.
• Built-in --update command to keep the local compatibility databases up to date.

Installation

# npm install -g @bramus/caniuse-cli

Usage

$ caniuse viewport-units
$ caniuse "viewport units"
$ caniuse @property

Updating the Compatibility Data

When your local caniuse-db or @mdn/browser-compat-data data is 30 days or older, caniuse will display a reminder to update. You can update the local databases (caniuse-db, @mdn/browser-compat-data, and web-features) at any time by running:

$ caniuse --update

Enable Tab Autocompletion

In zsh:

echo '. <(caniuse --completion)' >> ~/.zshrc

In bash:

caniuse --completion >> ~/.caniuse.completion.sh
echo 'source ~/.caniuse.completion.sh' >> ~/.bashrc

In fish:

echo 'caniuse --completion-fish | source' >> ~/.config/fish/config.fish

That's all!

Now you have an autocompletion system.
