To modify the Node.js request default timeout time, we set the timeout property.

For instance, we write

const http = require("http");
const server = http
  .createServer((req, res) => {
    setTimeout(() => {
      res.writeHead(200, { "Content-Type": "text/plain" });
      res.end("Hello World\n");
    }, 200);
  })
  .listen(1337, "127.0.0.1");

server.timeout = 20;
console.log("Server running at http://127.0.0.1:1337/");

to create a web server with createServer.

And we set the request timeout by setting the server.timeout property to a time milliseconds.

To store DB config in a Node.js and Express app, we store it in an .env file.

For instance, we write

DATABASE_PASSWORD=pw
DATABASE_NAME=some_db

in our .env file.

Then we write

require("dotenv").config();
const password = process.env.DATABASE_PASSWORD;

to load the .env file with the dotenv package.

And then we get the DATABASE_PASSWORD environment variable value with process.env.DATABASE_PASSWORD.

To fix ‘gulp’ is not recognized as an internal or external command with JavaScript, we install the gulp package.

To install it, we run

npm install -g gulp

to install gulp globally.

To get Mongoose connect error with Node, we call connect with a callback as the 2nd argument.

For instance, we write

mongoose.connect("mongodb://localhost/dbname", (err) => {
  if (err) {
    throw err;
  }
});

to call connect with a callback as the 2nd argument.

We get connection errors from err if there’s any.

To fix libsass bindings not found when using node-sass in Node, we upgrade to gulp-sass 2.

To do this, we run

npm uninstall --save-dev gulp-sass
npm install --save-dev gulp-sass@2

to uninstall the original version of gulp-sass with npm uninstall.

Then we install gulp-sass 2 with npm install.
