autoprefixer-cli

library1.0.0jsnpmunverified

Legacy CLI wrapper for Autoprefixer, version 1.0.0. This tool allows adding vendor prefixes to CSS from the command line but is no longer actively maintained. It was the original CLI for Autoprefixer before postcss-cli became the official successor. Release cadence is zero; the package has not been updated since its initial release. Key differentiator: it provides a simple autoprefixer-cli command for users who cannot migrate to PostCSS. However, users should prefer postcss-cli or directly integrate Autoprefixer via PostCSS for modern projects.

Verified usage

autoprefixer-cli

✓ npx autoprefixer-cli -o output.css input.css

✗ autoprefixer-cli input.css output.css

CLI expects -o flag before output file; positional arguments are not supported. Use npx for temporary execution.

package.json (bin)

✓ installed globally, run via `autoprefixer-cli`

✗ local install with `node_modules/.bin/autoprefixer-cli` or `npx autoprefixer-cli`

Package is intended for global install; local install may cause PATH issues. npx works for ad-hoc use.

help command

✓ autoprefixer-cli -h

✗ autoprefixer-cli --help

Uses `-h` for help, not `--help`. The `--help` flag may not work or produce output.

Installs the legacy CLI globally, creates a simple input CSS, runs autoprefixer, and displays the prefixed output.

# Install globally npm install -g autoprefixer-cli # Create a sample CSS file echo "body { display: flex; }" > input.css # Add vendor prefixes to output.css autoprefixer-cli -o output.css input.css # Check the result cat output.css

Debug

Known issues

deprecatedautoprefixer-cli is deprecated in favor of postcss-cli. Use postcss-cli with the autoprefixer plugin for long-term support.

fix

Migrate to postcss-cli: npm uninstall -g autoprefixer-cli; npm install -g postcss-cli autoprefixer

affects: *

gotchaThe -o flag is required before the output file. Using non-flag positional arguments will cause unexpected behavior.

fix

Use correct syntax: autoprefixer-cli -o output.css input.css

affects: *

gotchaGlobal install is recommended. Local install via npm install autoprefixer-cli may not place the binary in PATH.

fix

Install globally: npm install -g autoprefixer-cli, or use npx autoprefixer-cli

affects: *

gotchaHelp flag is -h, not --help. Using --help may print nothing or error.

fix

Use autoprefixer-cli -h

affects: *
