The Electron Ext JS Starter project template is based on this Sencha guide and has been modified so that you don't need to build your Ext JS application every time you want to test it in Electron. It makes use of the electron-routes package (as a substitute for a full web server, which is a good idea for security reasons) and demonstrates paginating an array of data in a grid.
- Sencha Ext JS 6.2.0 GPL v3 version or the 30 day trial version
- Sencha Cmd 6.5.1+ build tool (requires Java)
- Node.js 6.11+
$ git clone https://github.com/mfearby/electron-extjs-starter.git
$ cd electron-extjs-starter
Create a client/ext folder and extract a copy of the Ext JS framework into it (as per the pre-requisites above).
$ cd client
$ sencha app build development
$ cd ..
$ npm install
$ npm run plain
After cloning the repository you should npm run plain because the default npm start loads the production version of the Ext JS app, which you won't have built yet. The development build also recreates the bootstrap files.
The production (minified) version of the app is generated and copied to the client_build folder.
$ chmod 755 buildext.sh
$ ./buildext.sh
$ npm start
$ ./buildext
$ npm start
The package script calls the existing build script (above) to minify the Ext JS app then calls the Electron Packager script to bundle everything together with Electron for distribution (in the dist folder).
$ chmod 755 package.sh
$ ./package.sh
$ ./package
If you don't want to clone this repository and end up with an Ext JS project called "StarterApp", follow these steps to create a similar project structure.
$ npm init
$ npm install electron --save-exact --save-dev
$ npm install electron-packager --save-dev
$ npm install electron-routes --save
$ sencha -sdk /path/to/ExtSDK generate app -classic MyApp ./client
Create the main.js file and copy the contents from the file in this repository.
$ cd client
$ sencha app build -des ../client_built
$ cd ..
Copy the scripts block from the package.json in this repository to your local version.
$ npm start
$ npm run-script package
