Introduction

// router.js
import { Application } from 'egg';
import { wrapper } from '../lib';
export default (app: Application) => {
  wrapper(app, {
    // // [optional] default is /swagger-html
    // swaggerHtmlEndpoint: '/sw',
    // // [optional] default is /swagger-json
    // swaggerJsonEndpoint: '/sj',
    // // [optional] default is false. if true, will call makeSwaggerRouter(app) automatically
    // makeswaggerRouter: false,

    title: 'foo',
    version: 'v1.0.0',
    description: 'bar',
    // autoMount 是否开启
    // defaultRequestMounte: true
  });
  makeSwaggerRouter(app);
};

using decorator to make api definition

// controller/test.ts
import { Controller, Context } from "egg";
import {
  request,
  summary,
  path,
  tags,
  responses,
  middlewares,
  description,
} from "@grfe/egg-swagger-decorator";
import { PathParamsVO, IGetUserResultVO, IUserListVO } from "../dto";
const testTag = tags(["test"])
export default class Test extends Controller {
  @request("get", "/users")
  @description("get user list")
  @testTag
  @middlewares(async (ctx: Context, next) => {
    ctx.logger.info("mid");
    await next();
  })
  @responses(IUserListVO)
  public async getUsers() {
    const { ctx } = this;
    const users = [{ name: "cjfff" }];
    ctx.body = { users };
  }

  @request("get", "/users/{id}")
  @summary("get user info by id")
  @testTag
  @path(PathParamsVO)
  @responses(IGetUserResultVO)
  public async getUser() {
    const { id } = this.ctx.params;
    this.ctx.body = { id };
  }
}

dto define

// ../dto.ts
export class PathParamsVO {
  @ApiProperty({
    type: "number",
    description: "用户id",
    example: 10086,
  })
  @IsNumber({ maxDecimalPlaces: 1000 }, { message: "id 必须是数字2323232" })
  id: number;
}


export class IUserVO {
  @ApiProperty({
    type: 'string'
  })
  name: string;
}

export class IUserListVO {
  @ApiProperty({
    type: IUserVO,
    isArray: true
  })
  users: IUserVO[]
}


export class IGetUserResultVO {
  @ApiProperty({
    type: 'number'
  })
  id: number;
}
