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

• Instant, offline, results powered by caniuse-db and @mdn/browser-compat-data.
• 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.

# npm install -g @bramus/caniuse-cli

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

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.

bash: _get_comp_words_by_ref: command not found
bash: __ltrim_colon_completions: command not found
bash: _get_comp_words_by_ref: command not found
bash: __ltrim_colon_completions: command not found

Solution: install bash-completion package
