posthtml-render
Advanced tools
The posthtml-render package is a utility for rendering PostHTML tree structures into HTML strings. It is commonly used in conjunction with PostHTML parsers and plugins to transform and generate HTML content programmatically.
Basic HTML Rendering
This feature allows you to render a basic HTML structure from a PostHTML tree. The code sample demonstrates rendering a simple div element with text content.
const render = require('posthtml-render');
const tree = [{ tag: 'div', content: 'Hello, World!' }];
const html = render(tree);
console.log(html); // <div>Hello, World!</div>Nested HTML Elements
This feature allows you to render nested HTML elements. The code sample shows how to create a div element containing a nested span element.
const render = require('posthtml-render');
const tree = [{ tag: 'div', content: [{ tag: 'span', content: 'Nested content' }] }];
const html = render(tree);
console.log(html); // <div><span>Nested content</span></div>Attributes Handling
This feature allows you to add attributes to HTML elements. The code sample demonstrates rendering an anchor tag with an href attribute.
const render = require('posthtml-render');
const tree = [{ tag: 'a', attrs: { href: 'https://example.com' }, content: 'Click here' }];
const html = render(tree);
console.log(html); // <a href="https://example.com">Click here</a>htmlparser2 is a fast and forgiving HTML/XML parser. It can be used to parse HTML into a DOM-like structure, which can then be manipulated and rendered back to HTML. Compared to posthtml-render, htmlparser2 offers more comprehensive parsing capabilities but requires additional steps to render HTML.
Cheerio is a fast, flexible, and lean implementation of core jQuery designed specifically for the server. It parses HTML and XML documents and provides a jQuery-like API for manipulating the resulting structure. Cheerio is more feature-rich in terms of DOM manipulation compared to posthtml-render, but it is also heavier and more complex.
jsdom is a JavaScript implementation of the WHATWG DOM and HTML standards, primarily intended for use with Node.js. It allows you to create and manipulate a full DOM environment, including rendering HTML. jsdom is more powerful and comprehensive than posthtml-render, but it is also more resource-intensive.
