nestjs

问题 I'm migrating a NodeJs project to NestJs, this project uses MongoDB as back-end database and Mongoose as ODM. I was using the mongoose-sequence plugin to handle autoincrement sequences, however I'm facing troubles requiring the library under NestJs. The mongoose-sequence documentation explains how to import the library using CommonJS syntax as follows: const mongoose = require('mongoose') const AutoIncrementFactory = require('mongoose-sequence'); const connection = await mongoose

问题 Is there a way to automatically provide all @Global modules into a TestModule ? (i.e without having to import them, the same way the main application works) So far, I had to make sure to insert any global modules into the import list of my call: await Test.createTestingModule({ imports: [ GlobalModule1, GlobalModule2 回答1: Global modules always have to be imported once for their providers to be available globally. This holds true for tests and the main application, see the docs. Global modules

问题 Using Nestjs I'd like to get a list of all the available routes (controller methods) with http verbs, like this: API: POST /api/v1/user GET /api/v1/user PUT /api/v1/user It seems that access to express router is required, but I haven found a way to do this in Nestjs. For express there are some libraries like "express-list-routes" or "express-list-endpoints". Thanks in advance! 回答1: I just found that Nestjs app has a "getHttpServer()" method, with this I was able to access the "router stack",

问题 I am fairly new to NestJS + Typescript + RxJs tech stack. I am trying to write a unit test case using Jest for one of my functions but not sure if doing it correctly. component.service.ts public fetchComponents(queryParams) { const url = this.prepareUrl(queryParams); const data$ = this.httpService.get(url); return data$ .pipe(map(({ data }) => data)); } component.sevice.spec.ts Test case works and passes describe('fetchComponents', () => { const query = { limit: 10, offset: 0 }; const result:

问题 Im struggling with a problem. Im following the documentation of NestJS. The back-end framework for NodeJS. The documentation mentions a DTO (Data Transfer Object). I created a DTO for creating a user: export class CreateUserDto { readonly email: string; readonly password: string; } In combination with this: @Post('create') createUser(@Body() userData: CreateUserDto): User { return this.usersService.createUser(userData); } For some reason, I am able to make a post request to this route with

问题 I have an issue with the async pipe running on SSR. there are no errors, only an infinite loop (it seems that the server is waiting for the observable to be resolved). I am using: @nestjs/ng-universal Angular 9 Firebase Rxjs A simple case like this works: <p>{{ observable | async }}</p> But using structural directives do not work: ngIf <p *ngIf="(observable$ | async) > 5">{{ observable$ | async }}</p> Ngfor <p *ngFor="let item of items | async">{{ item }}</p> Using async is a good practice
