React +Mobx

The loader configuration is as follows
swc-loader Set decorators: true，Compile without any errors，But The menu bar is blank because the @unobservable @computed @action decoration symbol is not correctly recognized

Remove the @ unobservable @ computed @ action decoration from the code, and the page will display normally

{
test: /.(j|t)s(x)?$/,
exclude: /node_modules/,
loader: 'builtin:swc-loader',
options: {
// js/ts编译配置
jsc: {
parser: {
// 开启ts编译
syntax:'typescript',
// 开启tsx编译
tsx: true,
// 开启@装饰器编译
decorators: true,
// 动态import
dynamicImport: true,
},
transform: {
// react运行环境配置
react: {
// dev模式打开development启动react的开发模式
development: isDevelopment,
refresh: isDevelopment,
},
// stage 1 的旧版本class decorators
legacyDecorator: true,
// 支持 ts emitDecoratorMetadata
// decoratorMetadata: true,
},
},
