How to Solve Material-UI's `fade` Utility Renamed to `alpha` Error

If you are using Material-UI's `fade` utility in your JavaScript code, you may have encountered the following error:

colorManipulator.js:234 Material-UI: The `fade` color utility was renamed to `alpha` to better describe its functionality. You should use `import { alpha } from '@material-ui/core/styles'`

This error is caused by a recent update to Material-UI where they have renamed the `fade` utility to `alpha` for better clarity and consistency with other color-related utilities. Therefore, you should use the new `alpha` utility instead of the old `fade` utility in your code.

Solution 1: Using `import { alpha } from '@material-ui/core/styles'`

To fix the error, you should replace all instances of `fade` with `alpha` in your code, and import the new `alpha` utility from the `@material-ui/core/styles` module.

Here is an example of how to use the new `alpha` utility:

import { alpha } from '@material-ui/core/styles';

const myColor = '#ff0000';
const myAlphaColor = alpha(myColor, 0.5);
console.log(myAlphaColor);
// output: "rgba(255, 0, 0, 0.5)"

In the above example, we import the new `alpha` utility from the `@material-ui/core/styles` module and use it to create a new color with 50% opacity.

Solution 2: Creating a Custom `fade` Function

If you prefer to keep using the old `fade` utility in your code, you can create a custom function that maps `fade` to `alpha`:

import { fade as alpha } from '@material-ui/core/styles';

const myColor = '#ff0000';
const myAlphaColor = alpha(myColor, 0.5);
console.log(myAlphaColor);
// output: "rgba(255, 0, 0, 0.5)"

In the above example, we import the `fade` utility from the `@material-ui/core/styles` module and alias it as `alpha` using the `as` keyword. This allows us to continue using the old `fade` function in our code while avoiding the error.

Conclusion

To fix Material-UI's `fade` utility renamed to `alpha` error, you should replace all instances of `fade` with `alpha` in your code and import the new `alpha` utility from the `@material-ui/core/styles` module. Alternatively, you can create a custom function that maps `fade` to `alpha`.
