Tips for transforming a JSON object (originated from jquery-css-parser) into properly formatted CSS code

Currently, we are utilizing a jQuery plugin in our project to convert CSS to a JSON object. The plugin can be found at the following link:

Now, we have a requirement to convert the JSON object back to CSS in string format.

Unfortunately, the plugin we are using does not provide a way to convert JSON back to CSS. It successfully converts CSS to JSON, and the structure it generates is ideal for our needs. However, we also need a method to convert the JSON object back to CSS.

Is there a solution available that can convert the JSON object generated by this plugin back to CSS?

Here is an example of the JSON object that needs to be deserialized:

{
  'div div:first' : {
    'font-weight' : 'bold',
    'color': 'rgba(255,255,255,0.5)'
  },
  'div > span' : {
    'color': 'red'
  }
}

Additional details: I might have overlooked a feature of the plugin that performs this task, but I have thoroughly reviewed the documentation.

I also stumbled upon another plugin that converts to JSON and back, but the JSON format it uses is significantly different from the format we are currently working with. https://github.com/aramk/CSSJSON

Answer №1

Give this a shot:

let cssString = "";

// Assume that cssJSON is the object containing your CSS properties.
for (let selector in cssJSON) {

    // selector represents the CSS selector and the key in the object.
    cssString += selector + " {";

    let properties = cssJSON[selector];
    for (let property in properties) {
        cssString += property + ": " + properties[property] + ";";
    }

    cssString += "}";
}

Keep in mind that this code has not been thoroughly tested, so be cautious when implementing it. It might not cover all possible scenarios.

If you're looking for assistance with parsing CSS using JavaScript, you might want to check out the JavaScript CSS Parser tool available at this link.

This tool is quite straightforward to use. Suppose you have your entire CSS code stored as a string named cssString:

var parser = new CSSParser();
var serialized = parser.parse(cssString, false, true);

The above code will create a JSON serializable object representing your CSS stylesheet.

You can then easily loop through all your CSS rules and examine them. Here's an example:

var firstRule = serialized.cssRules[0]; // Accesses the first CSS rule defined
var thirdDeclaration = firstRule.declarations[2]; // Retrieves the third declaration in your first CSS rule
console.log(thirdDeclaration.property); // Prints out the property value

For instance, if your serialized string contains the following CSS code:

body {
   color: black;
   width: 50px;
   height: 70px;
   text-align: center;
}

p {
   color: red;
}

The snippet above would output 70px, which corresponds to the value of the third declaration (height) in the first defined CSS rule (body).

You can implement logic to iterate through the serialized CSS JSON object and convert it back to a CSS file or dynamically apply the rules to your HTML elements. The tool provides all the necessary information about the CSS rules.

I trust this explanation has been beneficial to you!

PS: The greatest advantage is that it doesn't require jQuery! :D (Using jQuery won't cause any issues either)
