I'm wondering, on a storybook, where is the best place to set my MUI X license key

Can you help with where to specify my license key in Storybook?

I need guidance on where to set the license key in Storybook. According to MUI Docs, it should be done before React renders the first component and only once in the application.

However, I keep encountering the message License key expired when trying to define my license either in the story or the component index file.

Answer №1

To implement this functionality, modify the .storybook/preview.js file as follows:

import { customTheme } from "../src/styles";
import { ThemeProvider } from "@mui/material";
import { LicenseInfo } from "@mui/x-license-pro"    

export const decorators = [
(Story) => {
LicenseInfo.setLicenseKey(process.env.REACT_APP__MUI_KEY);

return (
  <ThemeProvider theme={customTheme}>
    <Story />
  </ThemeProvider>
);
}];
  • The license key is stored in a separate .env file to be accessed by both the React application and Storybook. Ensure that the variable is prefixed with REACT_APP__
  • In this demo, we are showcasing the usage of a custom theme, which is applied to the story (you would do something similar with React Router).

Answer №2

It appears that this issue can be fixed by inserting the license key into .storybook/preview.js:
