Dynamic Background Color in Next.js with Tailwind CSS: Issue and Solution

Issue Description

I encountered an issue while working on a Next.js project using TypeScript. The goal was to dynamically set the background color of a component based on a status ID. Here is the initial implementation:

const statusColor = getStatusColor(status_id); // e.g., #ffff00, #ff9900, #ff0000, #33ff33
<div className="flex flex-col">
    <div
        className={`flex h-14 items-center justify-center space-x-4 rounded-md border bg-[${statusColor}] p-4 text-white`}
    >
        <div className="flex-1 space-y-1"></div>
    </div>
</div>

However, this approach did not work as expected when running npm run dev in a Next.js environment. The dynamic class for the background color was not applied correctly.

Observations

1. Initial Attempt: The class containing the dynamic color value (bg-[${statusColor}]) did not apply the background color as intended during development.
2. Temporary Workaround: Changing the dynamic property to a fixed value and then reverting it back to the dynamic value seemed to work temporarily. However, this workaround only lasted until the server was restarted.
3. Current Solution: To address this issue, I applied the background color using the style attribute instead of relying on dynamic Tailwind CSS classes.

Revised Code

const statusColor = getStatusColor(status_id);
<div className="flex flex-col">
    <div
        className="flex h-14 items-center justify-center space-x-4 rounded-md border p-4 text-white"
        style={{ backgroundColor: statusColor }}
    >
        <div className="flex-1 space-y-1"></div>
    </div>
</div>

By forcefully setting the background color via the style prop, the color is assigned correctly during compilation.

Explanation of getStatusCode Function

The getStatusColor function retrieves the color associated with a given status ID from a predefined list of status descriptions. Here is the relevant code:

import { statusInfo } from '@/data/status-descriptions/status-descriptions';

export function getStatusColor(status_id: string) {
    const defaultColor = 'black';
    const status = statusInfo.find((status) => status.key === status_id);
    console.log('Status:', status);
    const statusColor: string = status ? status.color : defaultColor;

    return statusColor;
}

Status Info Code

The statusInfo array is generated from a detailed description of various statuses:

export const STATUS_DESCRIPTIONS: Record<string, Status> = {
    green: {
        color: '#33ff33',
        description: {
            lang: 'en',
            text: 'No significant activity',
        },
        meaning: {
            lang: 'en',
            text: 'Aurora is unlikely to be visible by eye or camera from anywhere in the UK.',
        },
    },
  {
  ...
  }
}

export const statusInfo = Object.entries(STATUS_DESCRIPTIONS).map(
    ([key, { color, description, meaning }]) => ({
        key,
        color,
        description: description.text,
        meaning: meaning.text,
    }),
);

Conclusion

This solution ensures that the background colour is applied correctly irrespective of the server's state. Although using the style prop is not as elegant as leveraging Tailwind CSS classes, it guarantees the desired functionality. Further investigation may be required to determine why the dynamic class approach fails and whether a more integrated solution within the Tailwind CSS framework exists.

Please feel free to reach out if any questions or further clarifications are needed.

As per the documentation:

The most important implication of how Tailwind extracts class names is that it will only find classes that exist as complete unbroken strings in your source files.

If you use string interpolation or concatenate partial class names together, Tailwind will not find them and therefore will not generate the corresponding CSS:

Don’t construct class names dynamically

<div class="text-{{ error ? 'red' : 'green' }}-600"></div>

In the example above, the strings text-red-600 and text-green-600 do not exist, so Tailwind will not generate those classes.
Instead, make sure any class names you’re using exist in full:

Always use complete class names

<div class="{{ error ? 'text-red-600' : 'text-green-600' }}"></div>
