Quelltext der Seite SAPUI5 Local Development and Deployment

This article describes all necessary steps to create a local development environment in order to develop and run SAPUI5 apps locally with the use of remote servers for data retrieval.

Also it describes how to deploy a developed SAPUI5 app to a local server.

The following instructions are tested on:

* Windows 10 Version 20H2 Build 19042.685

== Prerequisites ==

Following software needs to be installed locally:

* Node.js >= 8.5 --> https://nodejs.org/download
* npm >= 5
* Git >= 2.1 --> https://git-scm.com/downloads/
* CLI, i.e. PowerShell or cmd.exe
* Code Editor, i.e. Notepad, VIM, Emacs, Eclipse or Visual Studio Code

Check versions:

 node -v
 npm -v
 git --version

== Installation of SAPUI5 Runtime Environment ==

'''Install UI5 Tooling and Verify Installation'''

 npm install –global @ui5/cli
 ui5 --help

'''Clone Project'''

i.e.:

 git clone https://github.com/mattxdev/openui5-basic-local-app/
 cd openui5-basic-template-app 

'''Install Dependencies'''

 npm install

'''Run Local Development Server'''

 ui5 serve -o index.html

This should open a Server at http://localhost:8080/ and run the http://localhost:8080/index.html

== Install local CORS Proxy ==

As it is not a good practice to access different domains from a web app the Chrome Browser will result in CORS errors in the console and the data will not be fetched.

In order work around that limitation a local proxy can be installed. In this repository the ''CORS anywhere'' proxy will be used. It is implemented in the '''proxy.js''' and in the '''package.json''' files.

'''Run CORS Proxy Server'''

The CORS proxy server should be run before the UI5 server by issuing:

 npm run proxy

== Create and Deploy a Standalone App to a Local Web Server ==

If a SAPUI5 app is deployed to the local machine, i.e. for testing, a ui5.yaml file will be needed, and probably a CORS proxy server too. 

The ''package.json'' needs to be adapted to consume the UI5 tooling for local defelopment. For more details see openSAP course UI52 and exercise: Week 4 Unit 5: Building and Deploying Your App

Install dependencies:

 npm install

Create ui5.yaml file:

 ui5 init

Generate a preload bundle in the DIST folder just like the build process in the SAP Web IDE:

 ui5 build --all

The ''--all'' option makes sure to also build the dependencies, i.e. themes, or make resources like i18n available.

The DIST folder can now be deployed to a standalone web server. Therefore install "serve" web server (version 6)

 npm install --global serve@6

Start CORS proxy, if needed:

 npm run localproxy

Go to the UI5 folder of the app and start the server with parameter for the DIST folder:

 serve ./dist

Generate self containted build:

 ui5 build self-contained --all
 serve ./dist

All UI5 modules used in the application will be analyzed, which controls are defined and used in the application and if needed they are all bundled together in the ''sap-ui-custom.js'' file.
