inline-style-prefixer

What is inline-style-prefixer?

The inline-style-prefixer is a JavaScript library used for automatically adding vendor prefixes to CSS styles defined in JavaScript objects. This is particularly useful when developing React applications that handle styles primarily in JavaScript. The prefixer uses the user agent to determine which prefixes are necessary for the current browser, ensuring cross-browser compatibility for CSS properties that require vendor prefixes.

What are inline-style-prefixer's main functionalities?

Automatic Prefixing

Automatically adds necessary CSS vendor prefixes to style objects based on the current browser's requirements.

{"display": 'flex'} // becomes {'display': ['-webkit-box', '-moz-box', '-ms-flexbox', '-webkit-flex', 'flex']} after processing

User Agent Based Prefixing

Initializes the prefixer with a specific user agent to tailor the prefixing process to a particular browser's needs.

const prefixer = new Prefixer({userAgent: 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36'}); const style = prefixer.prefix({display: 'flex'});

Other packages similar to inline-style-prefixer

autoprefixer

Autoprefixer is a more robust solution that integrates with build tools like PostCSS to automatically add vendor prefixes to CSS files. Unlike inline-style-prefixer, which is designed for inline styles in JavaScript, Autoprefixer works with static CSS files, making it suitable for a broader range of web development tasks.

postcss-prefixer

PostCSS-prefixer is a PostCSS plugin that allows developers to add prefixes to CSS properties manually. It requires explicit configuration for each prefix, offering more control but less automation compared to inline-style-prefixer, which automatically determines necessary prefixes.

Browser Support

It supports all major browsers with the following versions. For other, unsupported browses, we automatically use a fallback.

• Chrome: 55+
• Android (Chrome): 55+
• Android (Stock Browser): 5+
• Android (UC): 11+
• Firefox: 52+
• Safari: 9+
• iOS (Safari): 9+
• Opera: 30+
• Opera (Mini): 12+
• IE: 11+
• IE (Mobile): 11+
• Edge: 12+

It will only add prefixes if a property still needs them in one of the above mentioned versions.
Therefore, e.g. border-radius will not be prefixed at all.
