无法使属性依赖注入在React项目中工作

Question

我需要使用类似于C#或Java的语法方式为react项目注入一些真正基本的依赖项。通过道具使用上下文或注入不是一种选择。到目前为止，我尝试了三种解决方案：

• 倒置
• 可逆-反应-装饰器
• React.DI

然而，这些解决方案都不起作用，如果存在某种配置问题，就会引发问题。

使用倒装/反编译的-React Decorator/ Rect.DI

SomeService.ts

import { inject, injectable } from "inversify";
import { TYPES, ITokenProvider, IFileService } from "../injectables";
import { lazyInject, DIContainer } from "../inversify.config";

export class SomeService {

    @inject(TYPES.ITokenProvider) private tokenProvider!: ITokenProvider;      //Inversify
    //@lazyInject(TYPES.ITokenProvider) private tokenProvider!: ITokenProvider;//Inversify-r-d
    //@Inject tokenProvider!: TokenProvider;                                   //react-di
     (...)
}

inversify.config.ts

import "reflect-metadata";
import { Container } from "inversify";
import getDecorators from "inversify-inject-decorators";

import { TYPES, ITokenProvider, } from "./injectables";
import { TokenProvider } from "./Services/TokenProvider"


const DIContainer = new Container();
DIContainer.bind<ITokenProvider>(TYPES.ITokenProvider).toConstructor(TokenProvider);


const { lazyInject } = getDecorators(DIContainer, false);

export { DIContainer, lazyInject }

injectables.ts

export interface ITokenProvider {
    getSomeToken(): Promise<string>
}

TokenProvider.ts

import "reflect-metadata";
import * as microsoftTeams from "@microsoft/teams-js";

import { injectable } from "inversify";
import { ITokenProvider } from '../injectables';

@injectable()
export class TokenProvider implements ITokenProvider {

    public constructor() { }

    public async getSomeToken(): Promise<string> {
        (...)
    }
}

App.tsx (由react di代替inversify.config使用)

@Module({
    providers: [
        { provide: AccessTokenProvider, useClass: AccessTokenProvider },
    ]
})

误差

React DI和Inversify将解析依赖项，导致属性的未定义错误。倒装装饰器会导致以下错误：

TokenProvider.ts:8 Uncaught ReferenceError: Cannot access 'SomeService' before initialization
    at Module.SomeService (VM8 main.chunk.js:248)
    at Module../src/inversify.config.ts (inversify.config.ts:11)
   (...)

Config

tsconfig.json

{
  "include": [
    "src/*"
  ],
  "compilerOptions": {
    "target": "es5",
    "jsx": "react",
    "allowSyntheticDefaultImports": true,
    "lib": [
      "dom",
      "dom.iterable",
      "esnext"
    ],
    "allowJs": true,
    "skipLibCheck": true,
    "esModuleInterop": true,
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true,
    "strict": true,
    "forceConsistentCasingInFileNames": true,
    "module": "esnext",
    "moduleResolution": "node",
    "resolveJsonModule": true,
    "isolatedModules": true,
    "noEmit": true,
    "types": [ "reflect-metadata" ]
  }
}

我还尝试在不同的类中移动"reflect-metadata"。
