express

问题 I am creating an app with typescript express node typeorm. I am having this issue where when I make a call through a service class to the database using typeorm, I get connection default was not found. Here are my code snippets: //dataservice class import { Connection, getConnection, EntityManager, Repository, getManager } from "typeorm"; export class LeaveDataService { private _db: Repository<Leave>; constructor() { this._db = getManager().getRepository(Leave); } /** * applyForLeave */

问题 I have been having some trouble getting the correct Express Request type working in Jest. I have a simple user registration passing with this code: import { userRegister } from '../../controllers/user'; import { Request, Response, NextFunction } from 'express'; describe('User Registration', () => { test('User has an invalid first name', async () => { const mockRequest: any = { body: { firstName: 'J', lastName: 'Doe', email: 'jdoe@abc123.com', password: 'Abcd1234', passwordConfirm: 'Abcd1234',

问题 I'm trying to test a function that gets data from an external API using axios. To keep my test function as close as possible to the real thing, I'm querying mock data I have in a file. Axios can't return data from local files, which is a security feature. So the solution I'm trying is spinning up a simple server in my test suite, serving the file there, and then running my tests. My test suite looks like this right now: import React from 'react'; import {shallow} from 'enzyme'; import express
