node-modules

问题 I am trying to do a homework for a mongodb uni course. They gave us some files, instructions are: run npm install mongodb then node app.js for some reason npm install does not create a node_modules directory but I don't see any build errors: mongo-uni/hw1-2$ npm install mongodb npm WARN package.json path@0.4.9 path is also the name of a node core module. npm http GET https://registry.npmjs.org/mongodb npm http 304 https://registry.npmjs.org/mongodb npm http GET https://registry.npmjs.org/bson

问题 When I was answering another question I came across a Node.js module with a top-level return statement. For example: console.log("Trying to reach"); return; console.log("dead code"); This works without any errors and prints: Trying to reach in the standard output but not " dead code " - the return actually ceased execution. But according to the specification of return statements in ECMAScript 5.1, Semantics An ECMAScript program is considered syntactically incorrect if it contains a return

问题 I was reading about path-mapping in tsconfig.json and I wanted to use it to avoid using the following ugly paths: The project organization is a bit weird because we have a mono-repository that contains projects and libraries. The projects are grouped by company and by browser / server / universal. How can I configure the paths in tsconfig.json so instead of: import { Something } from "../../../../../lib/src/[browser/server/universal]/..."; I can use: import { Something } from "lib/src/

问题 Basically, I am using javascript to scrape data from Google Play store using: 1-Request 2-Cheerios 3-QueryString I used Google Market API from Github which uses require as following: var request = require('request'); var cheerio = require('cheerio'); var qs = require('querystring'); But I am getting the following ReferenceError: require is not defined ...

问题 Problem at hand: I have XML on the client side and the server side, but there's no consistent way to parse XML on both sides. Most browsers have DOMParser. But Node.js doesn't have a built-in XML parser. There are lots of modules for Node.js for XML parsing, but I'm looking for a XML parser API that is consistent for both front-end and back-end. In other words, I'm looking for a XML parsing module that can be used in Node.js like this const parser = require(magic_library); const doc = parser

问题 I want to get user client's IP address. This is my code: const server = http2.createSecureServer({ key: fs.readFileSync('localhost.key'), cert: fs.readFileSync('localhost.crt') }); server.on('error', (err) => console.error(err)); server.on('stream', (stream, headers) => { console.log('Path:' + headers[':path']); console.log('User Agent:' + headers['user-agent']); console.log('Cookie:' + headers.cookie); stream.respond({ 'content-type': 'text/html', ':status': 200 }); stream.end('<h1>Hello

问题 I have an azure app service which I need to deploy through as part of a release definition in VSTS. To provide some context, it is a ASP.NET MVC app and uses Angular 2. It also has a package.json file. I have a VSTS build definition which includes a 'npm install' task to install all dependencies from package.json, so that I don't need to check in all the node modules. At the end of the build the files are dropped to a share without the node_modules folder. I have a corresponding release

问题 I have this async function in a file called index.main.js which has a variable , 'targetFiles' which I would like to export to another file which is index.js. Problem is I can't find a way to export the value of this particular variable without getting "undefined" as a result. I have tried implementing promise, callback , export default function, and doing countless hours of research to no avail. //this code is in index.main.js var targetFiles = ""; async function listFilesInDepth() { const

问题 I have a React native project which requires to change some code inside the Android project of some library. The problem is that the library is positioned inside the node_modules folder and it's not been saved when pushing to get, because node_modules is ignored. I know I can remove node_modules from .gitignore but I think there should me another way, some better practice? 回答1: Best way is that customize your module and use it from another address! for example I written many module and saved
