Framework for building complex, recursive OOP based real-time objects

x0 (cross-objects /krɒs ɒb.dʒɪkts/) is a Next-Level JavaScript Framework for building robust, complex, highly structured and real-time-modifiable objects usable in a 100%-Server-Less infrastructure.

• Responsive by Design: One app, every device, standards via Bootstrap CSS
• Clean OOP Model: True object orientation, abstraction, chaining, metadata modeling
• Zero Code Duplication: Efficient, maintainable, backend-agnostic
• Kubernetes Ready: Easy cloud-native deployment
• Security: PKCS 11/15 compatible, own PKI system (non-free)
• Multiple Language Support: x0 supports multiple display languages

# clone & enter repo git clone https://github.com/WEBcodeX1/x0.git cd x0 # install docker apt-get -y install docker.io docker-buildx # docker permissions & setup (as root) usermod -aG docker your-user # restart (system) and pull pre-built images docker pull ghcr.io/webcodex1/x0-app docker pull ghcr.io/webcodex1/x0-db docker pull ghcr.io/webcodex1/x0-test # start x0-system cd ./docker/ ./x0-start-containers.sh

1. Add to /etc/hosts:

172.20.0.10 x0-app.x0.localnet

2. Try hello world:

http://x0-app.x0.localnet/python/Index.py 

3. Try examples:

http://x0-app.x0.localnet/python/Index.py?appid=example7

• Cross Objects: Clean OOP, seamless data exchange between clients and network
• Responsiveness: Bootstrap CSS grid, single app for all devices
• Object Chaining / Data Abstraction: Chain objects, enjoy recursive, reusable modeling
• Zero Code Duplication / Freedom: OSI-layer abstraction, minimal backend dependencies
• Kubernetes Ready: Google Kubernetes Engine (GKE), Minikube support
• Security: PKCS-compatible, optional advanced PKI system

x0 is designed to make advanced SPA development fun, fast, and maintainable. With zero code duplication and a clean OOP model, x0 powers complex, modern web applications.

Single Page Applications (SPAs) are modern web apps that deliver a seamless, desktop-like user experience directly in the browser. Unlike traditional multi-page websites, SPAs dynamically update content without requiring full page reloads, resulting in faster interactions and smoother navigation.

• Real-Time Updates: By using technologies like WebSockets or polling, SPAs can reflect changes instantly — ideal for chat apps, dashboards, or any application requiring live data.
• Optimized Performance: Static assets are loaded once, and only data or components needed for each interaction are fetched afterward, reducing bandwidth and latency.

# define object from system objects let myRootObject1 = new sysBaseObject(); const myObject1 = new sysObjFormfieldItem(JSONConfig); const myObject2 = new sysObjLink(JSONConfig); const myObject3 = new sysObjButton(JSONConfig); myRootObject.addObject(myObject1); myRootObject.addObject(myObject2); myRootObject.addObject(myObject3); # register new system object sysRegister(myRootObject1, 'MyCoolObject'); # reuse and combine let myRootObject2 = new sysBaseObject(); const myObject4 = new sysObjMyCoolObject(JSONConfig); const myObject5 = new sysObjMyCoolObject(JSONConfig); myRootObject2.addObject(myObject4); myRootObject2.addObject(myObject5); # realtime render myRootObject2.renderObject();
