UI5 SDK on Node.js

[former_member182048]

I recently had to rebuild my laptop and one of the first things I did was to install Node.js and have it statically serve my UI5 SDKs, I thought I would share how easy it is to setup.

"Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications". Node.js has an easy to use command line utility npm for managing the JavaScript dependencies in your applications, npm can also be used for loading one of the many Node.js applications from the npm (Node Packaged Module) registry.  Besides using Node.js as an application platform it provides many tools to aid UI5 development, I use node hosted apps inside of Sublime Text for formatting and checking (linting) my code and use gruntjs for automating a lot of the repetitive test, build and deploy tasks, I even use generator-openui5 to create my UI5 mobile projects, views and controllers.

Start at the end

C:\sapui5\sdk is where i store the various UI5 SDK versions, also in that folder i have a JavaScript file static_server.js which has simple code to create a node server and publish the content within the directory

To run the server open up a windows command line window, <shift> <right click> on folder -> "Open command window here" then enter

node static_server

This command starts the server and opens up the default browser with directory listing

from here you can choose to run the SDK

or browse the directory and easily navigate and view the debug files in the browser

The code

static_server.js - put this file in the directory

var express = require('express'),

  open = require('open');

  app = express(),

  port = process.env.PORT || 8888,

  sapui5 = '/sapui5'

  url = 'http://localhost:' + port + sapui5,

  year = 60 * 60 * 24 * 365 * 1000;

// Use compress middleware to gzip content

app.use(express.compress());

//set default mime type to xml for ".library" files

express.static.mime.default_type = "text/xml";

// Serve up content directory showing hidden (leading dot) files

app.use(sapui5,express.static(__dirname, { maxAge: year, hidden: true }));

// enable directory listening

app.use(sapui5,express.directory(__dirname));

app.listen(port);

open(url); //open in default browser

console.log("Static file server running at\n  => " + url + " \nCTRL + C to shutdown")

In the above code expressjs a lightweight app framework creates compressed and cache-controlled content with directory listing and serves it at http://localhost:<port>/sapui5 , the open module opens the default browser application.

Installation

Installing Nodejs is very simple - goto nodejs.org and click on "Install",  the default installation has enough to get started.

Once you have Node.js installed open a command prompt in the directory where the SDK is located, then use npm to install expressjs and node open

this will load the module into the node_modules directory and do the same for open

npm install open

the preferred alternative to manually installing would be to create a package.json file in the directory and define the dependencies

{

  "dependencies" : {

    "express" : "3.x",

    "open" : "0.0.x"

  }

then run  "npm install" from the command line.

Once the dependencies are installed you should now be able to run the server

node static_server

Enjoy 🙂
