Environment Utilities
Provides utilities to check the current environment, which is useful for conditional logic based on the environment.
const { isDev, isProd } = require('@umijs/utils');
if (isDev()) {
console.log('Running in development mode');

console.log('Running in production mode');
}
Logging Utilities
Includes logging utilities with color support via chalk, making it easier to format and display log messages.
