css-stringify

What is css-stringify?

The css-stringify npm package is used to convert a CSS Abstract Syntax Tree (AST) into a CSS string. This is useful for scenarios where you need to programmatically generate or manipulate CSS styles and then convert them back into a string format for use in stylesheets or inline styles.

What are css-stringify's main functionalities?

Basic CSS Stringification

This feature allows you to convert a CSS AST into a CSS string. The example demonstrates how to create a simple AST for a CSS rule and then convert it into a string.

const stringify = require('css-stringify');
const ast = {
  type: 'stylesheet',
  stylesheet: {
    rules: [
      {
        type: 'rule',
        selectors: ['.example'],
        declarations: [
          {
            type: 'declaration',
            property: 'color',
            value: 'red'
          }
        ]
      }
    ]
  }
};
const cssString = stringify(ast);
console.log(cssString); // Outputs: .example {\n  color: red;\n}

Handling Multiple Rules

This feature demonstrates how to handle multiple CSS rules within a single AST and convert them into a CSS string. The example shows two different CSS rules being stringified.

const stringify = require('css-stringify');
const ast = {
  type: 'stylesheet',
  stylesheet: {
    rules: [
      {
        type: 'rule',
        selectors: ['.example1'],
        declarations: [
          {
            type: 'declaration',
            property: 'color',
            value: 'blue'
          }
        ]
      },
      {
        type: 'rule',
        selectors: ['.example2'],
        declarations: [
          {
            type: 'declaration',
            property: 'background',
            value: 'yellow'
          }
        ]
      }
    ]
  }
};
const cssString = stringify(ast);
console.log(cssString); // Outputs: .example1 {\n  color: blue;\n}\n.example2 {\n  background: yellow;\n}
