Mongoose find all documents where array.length is greater than 0 & sort the data

由 我的未来我决定 提交于 2021-02-18 04:07:13
问题 I am using mongoose to perform CRUD operation on MongoDB. This is how my schema looks. var EmployeeSchema = new Schema({ name: String, description: { type: String, default: 'No description' }, departments: [] }); Each employee can belong to multiple department. Departments array will look like [1,2,3]. In this case departments.length = 3. If the employee does not belong to any department, the departments.length will be equal to 0. I need to find all employee where EmployeeSchema.departments

问题 I am writing my first cloud function for Firebase and it requires the firebase-tools module. I've installing it by adding it to my dependencies in the package.json file and running npm install . Then I tried to import it using import * as tools from 'firebase-tools'; , but I get this error: Could not find a declaration file for module 'firebase-tools'. 'c:/Users/LENOVO/Nouveau dossier/functions/node_modules/firebase-tools/lib/index.js' implicitly has an 'any' type. Try npm install @types

Deploying a TCP server to Heroku

由 ≡放荡痞女 提交于 2021-02-18 03:02:04
问题 I have a TCP server coded in node.js. I'd like to put it up on Heroku because it's a free service and I don't need anything more than what their free plan offers. Now, I know very little about the inner workings of Heroku and I'm pretty new to the whole thing so I have a few questions. Firstly, is it even possible to deploy a TCP (non-web) server? I've read that Heroku doesn't like node.js's net because it doesn't support websockets and that I should use socket.io. So I've switched my server

【js】走近小程序

由 半腔热情 提交于 2021-02-18 01:13:58
一、什么是小程序？ 基于微信的可以为用户提供一些服务的web项目，利用微信提供的接口可以让所有开发者使用到微信的原生能力，去完成一些之前做不到或者难以做到的事情。 二、小程序开发工具以及语言？ 小程序需要用到微信提供的 小程序开发工具 ，​小程序的主要开发语言是 JavaScript 。 三、小程序与普通网页开发的区别？ ​网页开发渲染线程和脚本线程是互斥的，这也是为什么长时间的脚本运行可能会导致页面失去响应，而在小程序中，二者是分开的，分别运行在不同的线程中。网页开发者可以使用到各种浏览器暴露出来的 DOM API，进行 DOM 选中和操作。而如上文所述，小程序的逻辑层和渲染层是分开的，逻辑层运行在 JSCore 中， 并没有一个完整浏览器对象，因而缺少相关的DOM API和BOM API。 这一区别导致了前端开发非常熟悉的一些库，例如 jQuery、 Zepto 等，在小程序中是无法运行的。同时 JSCore 的环境同 NodeJS 环境也是不尽相同，所以一些 NPM 的包在小程序中也是无法运行的。 四、小程序的代码构成？ （1）在我们新建的小程序项目里面会有四种类型的文件。 .json 后缀的 JSON 配置文件 （静态配置信息）　　　　　　 .wxml 后缀的 WXML 模板文件（相当于原生html文件） .wxss 后缀的 WXSS 样式文件（相当于原生css文件）
