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
