问题 I am building a mobile only application in Node.js + MongoDB. I have deployed my server in the AWS AP-Southeast-1 Region . Since I am new to MongoDB, I am leveraging cloud hosting services like MongoLabs, Compose.IO, MongoDirector (testing a few out). Now, these cloud hosting platforms are deploying my database in either of the AWS AP-Southeast-2 OR US-East-1 Region due to unavailability of Shared hosting in the Southeast-1 Region. While testing my APIs, I saw a alarmingly high latency in the

问题 I open the Hackerrank example test and play around with methods one might use to make an AJAX call. XMLHttpReq , fetch , etc. None of them work; XHR and fetch methods are unavailable. First fetch : async function myFetch() { let response = await fetch('https://jsonplaceholder.typicode.com/todos/1'); let data = await response.json(); console.log(data); } Hackerrank throws an error because fetch is not a function. I also tried window.fetch and global.fetch to no avail. I tried XHR : function

问题 I'm trying to download a photo through a URL passed as a query string using Express, but every time I try to use it, I get Error: Invalid URI "favicon.ico" Is there a way I can get my browser to stop requesting a favicon? For downloading images, I'm using the image-downloader package (NPM page) Code: app.get('/:url', (req, res) => { let url = req.params.url; const options = { url: url, dest: /path' }; download.image(options) .then(({ filename, image }) => { console.log('File saved to ',

问题 I want to fetch the rows from a postgres table where name = SUPREME INT'L, Note: this string has a single quote in between the name characters.

问题 I'm wanting to include a .db database file for use with sqlite3 in my node.js project. My problem arises when the module which opens the database connection is required by files in different directories. My project structure is like so: project/ |--lib/ | |--foo.js | `--bar.js |--db/ | `--database.db `--server.js My foo.js file contains opens the database like so: var sqlite3 = require('sqlite3'); var db = new sqlite3.Database('db/database.db'); module.exports = { foo: function() { db

问题 Using node ssh2-sftp-client, I'd like to recursively list all directories (and in a second time, files) of a SSH-remote directory root. I'm using nodejs node v12.15.0 I've found a usefulness same but non answered StackOverflow question. Documentation "basic usage" (see ssh2-sftp-client) gives a standard use of sftp connection and list of directory '/tmp' : const Client = require('ssh2-sftp-client'); const sshConfig = { host: process.env.REMOTE_SSH_HOST, port: 22, username: process.env.REMOTE

问题 I'm trying to run the NextJS on a Docker container using Dockerfile and running via docker-compose, after I changed my code in a JS file (such as index.js) the Next server did not reload. But when I've tried to run outside without using Docker (by executing the "npm run dev" command directly) the Next server did reload smoothly. I've also tried to run the server by "nodemon" command (inside a container), it did not make it either. Dockerfile: FROM node:10.14.2-alpine COPY . /home/next_app
