How Midway v1.0 Simplifies Node.js Development with IoC and Decorators

On this celebratory day, the Midway team is excited to announce the release of Midway v1.0, the core product of the MidwayJs ecosystem.

The repository remains at https://github.com/midwayjs/midway; stars are welcome.

IoC‑based decoupling of business code with unified dependency management and initialization.

Decorator shortcuts for common web scenarios to simplify development.

Full compatibility with Egg.js plugins, unified coding style via framework decorators.

TypeScript‑based, interface‑driven programming experience.

Dependency injection is introduced into complex business logic, allowing developers to focus on domain code without worrying about instance creation or initialization.

@provide()
@controller()
export class HomeController {
  @inject()
  reportService: IReportService;

  @get('/')
  async index(ctx) {
    ctx.body = await this.reportService.getReport();
  }
}

@provide()
class ReportService implements IReportService {
  @inject()
  reporter: IReportManager;

  async getReport(id: number) {
    return await this.reporter.get(id);
  }
}

In the example, HomeController depends on ReportService without any explicit instantiation, thanks to the "magic" of dependency injection.

Additional useful decorators such as @schedule, @init, and @plugin are also provided.

Starring the repository is greatly appreciated and fuels continued development.
