Learn how to use GeoExt 3 in your ExtJS applications.
This assumes that Node.js is installed:
- Download the latest workshop-contents from this URL:
- Extract the zip-archive into a directory of your choice.
- You should find the following files and directories in the
geoext3-ws-master
-folder:LICENSE.md
package.json
README.md
src/
- Install the dependencies of the workshop via
npm install
. - Start the workshop server with
npm start
. - Open
http://localhost:4000
.
If you do not have Node.js installed (e.g. if you work on a fresh OSGeo-Live), you will need to install it. Here are some example commands you need to issue in a terminal to get everything the workshop depends upon.
First, let's install nvm
(Node Version Manager) which we use to manage installations of Node.js.:
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.1/install.sh | bash
Next, please close and reopen the terminal, so that the nvm
script is available.
Afterwards issue the following in the terminal to install the lates v6.x Node.js and a matching npm
utility:
nvm install v6
You can now follow the instructions above.
# Create a directory gx-ws and go there …
mkdir -p ~/gx-ws && cd ~/gx-ws
# … grab the zip-archive …
wget https://github.com/geoext/geoext3-ws/archive/master.zip
# … unzip the archive …
unzip master.zip
# … change into the extracted folder
cd geoext3-ws-master
# … install dependencies via npm
npm install
# … start the workshop server
npm start
The steps below can be run on a Windows machine. They have been tested on Windows 10 with PowerShell v5.1, and Visual Studio 2017.
# create a C:\gx-ws directory
$wsFolder = "C:\gx-ws"
New-Item -Path $wsFolder -ItemType Directory
# download the zip-archive
$client = New-Object System.Net.WebClient
$client.DownloadFile("https://github.com/geoext/geoext3-ws/archive/master.zip", "$wsFolder/master.zip")
# unzip the archive
Expand-Archive -Path $wsFolder/master.zip -DestinationPath $wsFolder
# install the chocolatey package manager
# if you have Visual Studio 2010+ and the Nugetextension installed you can run the
# commands below, otherwise see how to install at https://www.chocolatey.org/install
Install-Package chocolatey -Force
# now install nodejs with chocolatey
choco install nodejs -y
# change into the extracted folder
cd "$wsFolder/geoext3-ws-master"
# install dependencies via npm
npm install
# start the workshop server
npm start
If gitbook fails to install try running the following separately:
npm install gitbook-cli -g
During the workshop you will work with the following JavaScript libraries or frameworks:
- OpenLayers (4.6.5): http://openlayers.org/
- ExtJS (v6.2.0, GPL): https://www.sencha.com/products/extjs/
- GeoExt3 (v3.1.0): http://geoext.github.io/geoext3/
For developing and enhancing the workshop.
- Run
npm i && npm start
and visithttp://localhost:4000
- Edit the markdown files in
src/
- Edit exercise-files in
src/exercises/
- In the root directory of the repository
- run
npm install
… to install node dependencies (and those of gitbook, e.g. plugins) - Afterwards you can use certain
npm
scripts:npm start
… starts a development server which builds the HTML version of the workshop and serves it athttp://localhost:4000
. Changes to any of the input files insrc
will be instantly visible in the generated HTML. HitCtrl-C
to quit the development server. Changes to any files in thesrc/exercises
-directory are published directly tohttp://localhost:4000/exercises/
npm doc:build
… builds the HTML once and stores it atbuild/geoext3-ws
npm doc:pdf
… builds the PDF once and stores it atbuild/geoext3-ws.pdf
, requires thatcalibre
is installed (see below).npm doc:epub
… builds the EPUB once and stores it atbuild/geoext3-ws.epub
, requires thatcalibre
is installed (see below).npm run build:all
… cleans from previous builds and creates HTML, PDF and EPUB versions of the workshop atbuild
, requires thatcalibre
is installed (see below).npm run archive
… does whatnpm run build:all
does and creates an archive in zip-format inbuild/
, requires thatzip
is installed.
Certain scripts for creating a PDF or EPUB version need the calibre
program; follow the instructions on installing for your operating system.
