iso-web-template

Live Production Example

Welcome to the ISO World

My dear, here we must run as fast as we can, just to stay in place.
And if you wish to go anywhere you must run twice as fast as that.

— Lewis Carroll

What is this?

This is a tool set and example of how to create a production capable Spring Boot + React + Isomorphic Web Application. The example template can render any view on the server or browser identically. One of the major draw backs of using React in Nashorn is thread safety. Keeping the Nashorn Engine thread safe and not shared, causes performance issues. The Nashorn Thread Safety problem is solved here by integrating a new Spring View Resolver (TransView) with a Blocking Queue Resource Pool of THREAD-SAFE WARMED-UP NASHORN ENGINES. This repo provides a solution to the Nashorn Thread Safety problem as well as a tool set for many other issues you are likely to encounter as you navigate through the ISO World (TransView, TransAuth, and TransReact).

Instructions

How to run the production build

Checkout the iso-web-template project via git.

git clone https://github.com/TransEmpiric/iso-web-template.git

Insall all npm packages and run the global build from the trans-react root directory

cd iso-web-template/src/main/trans-react
npm install
npm run build

You can now serve the trans-react/ssr and trans-react/client modules from the iso-web-template root directory with Spring Boot.

cd ../../../
./gradlew bootRun

With the browser navigate to http://localhost:8080

How to run the development build

This will run a Webpack dev server

cd iso-web-template/src/main/trans-react/client
npm run dev

You may want to run the backend at the same time, which is Spring Boot, so...

cd ../../../../
./gradlew bootRun

With the browser navigate to http://localhost:3000 to use the WebpackDevServer

Notes:

The subjects within may be moved to sperate projects eventually and posted on Maven Central or NPM. There are lot of ideas here and not enough time to explain them all. Please take a look and help out if you can.
