What is the best way to display properly formatted code to users in a React JS application?

The backend is sending code to me in plain text format. Here's an example:

def countNegatives(matrix): count = 0 for row in matrix: for num in row: if num < 0: count += 1 return count

It's just basic text, but I need to show this to the user in a well-organized manner. Like the one below...

def countNegatives(matrix): 
    count = 0 
    for row in matrix: 
        for num in row: 
            if num < 0: 
                count += 1 
    return count

I want to display formatted code snippets for Javascript, Python, Java, C, C++, Ruby, and CSS. Can anyone guide me on how to achieve this? Any help would be highly appreciated...

Answer №1

If you're looking to format your code, consider using Prettier. While there are other libraries available for code formatting, creating a custom hook in React can be a helpful solution.

Answer №2

Raukaute, thank you for mentioning Prettier as a great formatting library. If you want to see it in action, check out the Prettier Playground or read more about it on the official documentation. The Playground itself is an impressive project built using React and the Prettier web worker. You can even explore its source code on Github.

To summarize, the index.js file sets up a WebWorker using the static UMD js file (prettier/standalone.js) and utilizes the format API within the App -> Playground -> PrettierFormat component hierarchy.

Answer №3

For optimal results, try utilizing the js-beautify tool.
While not flawless, it offers reliable performance.
