It means that using the bodyParser() constructor has been deprecated, as of 2014-06-19. app.use(bodyParser()); //Now deprecated You now need to call the methods separately app.use(bodyParser.urlencoded()); app.use(bodyParser.json()); And so on. If you’re still getting a warning with urlencoded you need to use app.use(bodyParser.urlencoded({ extended: true })); The extended config object key now needs to be explicitly … Read more
UPDATE: As Seyeong Jeong points out in their answer below, since npm 5.2.0 you can use npx [command], which is more convenient. OLD ANSWER for versions before 5.2.0: The problem with putting ./node_modules/.bin into your PATH is that it only works when your current working directory is the root of your project directory structure (i.e. … Read more

[This post is up-to-date as of 2012-09-02 (newer than above).] Node.js absolutely does scale on multi-core machines. Yes, Node.js is one-thread-per-process.

To check if any module in a project is ‘old’: npm outdated ‘outdated’ will check every module defined in package.json and see if there is a newer version in the NPM registry. For example, say xml2js 0.2.6 (located in node_modules in the current project) is outdated because a newer version exists (0.2.7). You would see: … Read more
Since Node.js v0.12 and as of Node.js v4.0.0, there is a stable readline core module. Here’s the easiest way to read lines from a file, without any external modules: const fs = require(‘fs’); const readline = require(‘readline’); async function processLineByLine() { const fileStream = fs.createReadStream(‘input.txt’); const rl = readline.createInterface({ input: fileStream, crlfDelay: Infinity }); // … Read more
