可以添加一个hashPrefix属性能自定义前缀吗

// Generate different prefix to make user selector break in production env.
// This helps developer not to do style override directly on the hash id.
var hashPrefix = process.env.NODE_ENV !== 'production' ? 'css-dev-only-do-not-override' : 'css';

Start by locating the TypeScript entry point that creates the hash id and tracing how NODE_ENV selects the current prefix. Define how a hashPrefix option should interact with the development and production defaults, then add coverage for custom and default behavior; done means selectors use the configured prefix without breaking existing defaults.
