node.js

问题 I've just seen this library ByteNode it's the same as ByteCode of java but this is for NodeJS. This library compiles your JavaScript code into V8 bytecode, which protect your source code, I'm wondering is there anyway to Decompile byteNode therefore it's not secure enough. I'm wondering because I would like to protect my source code using this library? 回答1: TL;DR It'll raise the bar to someone copying the code and trying to pass it off as their own.

I don`t know if there is any difference in using

问题 So, what I am trying to accomplish is basically: Generating a plot by using NodeJS and plotly for NodeJS and getting it into my filesystem (with getImage ), and proceeding with the image afterwards. My problem is, that the function returns before finishing and getting the image into my filesystem. So my result is basically that after I'm calling generate_plot() , the file does not exist yet and I'm getting an error. Now onto my question: How do I wait for generate_plot() to finish and to

问题 If a method of a module is called from within a file, can I tell the location of that file from within the module? So // my-module.js module.exports = { method: function () { // in here I would like to detect the path to my-app.js } } // my-other-module.js require('my-module').method(); I want some equivalent of access to __filename for my-other-module.js from within my-module.js. I don't want to have to pass __filename as a parameter 回答1: For a utility logging you could use this (I used

问题 I'm trying to validate the parameters that come in the query of a get request, but for some reason, the validation pipe is unable to identify the elements of the query. import { Controller, Post, Query, Body, UseInterceptors, Param, Res, Logger, } from '@nestjs/common'; import { Crud, CrudController, Override } from '@nestjsx/crud'; import { OpenScheduleDto } from './open-schedule.dto'; @Crud(Schedule) export class ScheduleController implements CrudController<ScheduleService, Schedule> {

问题 I have centOS: When I try to run an node.js app that requires express, I get the following error: module.js:340 throw err; ^ Error: Cannot find module 'express' at Function.Module._resolveFilename (module.js:338:15) at Function.Module._load (module.js:280:25) at Module.require (module.js:364:17) at require (module.js:380:17) at Object.<anonymous> (/var/www/tipsterPro/index.js:2:15) at Module._compile (module.js:456:26) at Object.Module._extensions..js (module.js:474:10) at Module.load (module

问题 While reading this article earlier, I came across the following line of code: import { run } from '@cycle/core'; Which led me to the following questions: What is the significance of the @ symbol, if any? Is there a difference between import 'foo/bar' and import '@foo/bar' ? Is it a way to resolve a particular type of module? I'm relatively new to ES6, although the import syntax seems pretty straightforward to me - except, in this case, for the cryptic presence of the @ symbol. I tried
