express-server-utils

What does it do?

This library facilitates handling listening, enables graceful shutdown, and creates friendly errors for express servers.

Quick Start

Several options to get up and running:

• Clone the repo: git clone https://github.com/alien35/express-server-utils
• Install with npm: npm install express-server-utils

example usage

const express = require('express');
const app = express();
const port = process.env.PORT || '3000';
app.set('port', port);
const server = http.createServer(app);

expressServerUtils = require('express-server-utils')(server, port);
expressServerUtils.listen();
expressServerUtils.handleOnError();
expressServerUtils.handleOnListening();

const exitActions = [server.close, db.destroy];
expressServerUtils.handleShutDown(exitActions);

Methods

listen Function

Configures the server to listen to the port.

handleOnError Function

Logs a friendly error depending on the error code and sends a process.exit(1) at the end. If error type is unknown, throws the error.

handleOnListening Function

Logs the port the server is listening to.

handleShutDown([Function]) Function

Before terminating the server, this function enables general cleanup by running a number of user-given commands. Example commands include

• server.close

• db.destroy
