The 'juice' npm package is primarily used for inlining CSS into HTML. This is particularly useful for sending HTML emails where inline styles are often required for consistent rendering across different email clients.
Inline CSS into HTML
This feature allows you to take an HTML string with embedded CSS and inline the CSS styles directly into the HTML elements. This is useful for ensuring that styles are applied correctly in environments that do not support embedded or external stylesheets, such as many email clients.
const juice = require('juice');
const html = '<html><head><style>h1 { color: red; }</style></head><body><h1>Hello, world!</h1></body></html>';
const inlinedHtml = juice(html);
console.log(inlinedHtml);Inline CSS from external stylesheets
This feature allows you to inline CSS from external stylesheets referenced in the HTML. The 'url' option is used to resolve the paths of the external stylesheets.
const juice = require('juice');
const html = '<html><head><link rel="stylesheet" href="styles.css"></head><body><h1>Hello, world!</h1></body></html>';
const inlinedHtml = juice(html, { url: 'http://example.com' });
console.log(inlinedHtml);Custom CSS inlining options
Juice provides various options to customize the inlining process. For example, you can choose whether to apply style tags, remove style tags after inlining, and more.
const juice = require('juice');
const html = '<html><head><style>h1 { color: red; }</style></head><body><h1>Hello, world!</h1></body></html>';
const options = { applyStyleTags: true, removeStyleTags: false };
const inlinedHtml = juice(html, options);
console.log(inlinedHtml);The 'inline-css' package is another tool for inlining CSS into HTML. It offers similar functionality to 'juice' but with a simpler API. It is useful for basic inlining tasks but may lack some of the advanced options available in 'juice'.
The 'premailer' package is a more comprehensive tool that not only inlines CSS but also rewrites URLs, adds missing HTML attributes, and more. It is a good alternative to 'juice' for more complex email preparation tasks.
The 'email-comb' package is designed to clean and optimize HTML emails by inlining CSS and removing unused styles. It is similar to 'juice' but focuses more on optimization and cleaning up the HTML.
