Nestjs 获取路由的方法

Express

方案一

// main.ts

import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import * as expressListRoutes from 'express-list-routes';

async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  app.enableCors();
  await app.listen(3000);


  const server = app.getHttpServer();
  const router = server._events.request._router;
  console.log(expressListRoutes({}, 'API:', router));

}
bootstrap();

方案二：

async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  await app.listen(3000);
  const server = app.getHttpServer();
  const router = server._events.request._router;

  const availableRoutes: [] = router.stack
    .map(layer => {
      if (layer.route) {
        return {
          route: {
            path: layer.route?.path,
            method: layer.route?.stack[0].method,
          },
        };
      }
    })
    .filter(item => item !== undefined);
  console.log(availableRoutes);
}
bootstrap();

注意以上的两种方案都是在app.listen之后添加代码。

Fastify

在main.ts 文件的app.listen之前插入如下代码：

app
    .getHttpAdapter()
    .getInstance()
    .addHook('onRoute', opts => {
      console.log(opts.url)
    })
