Support for instant launch of games without downloading
Introduction
Support for instant play means that the player can start any game right in the browser window in a split second - without installation, updates or long download. To ensure this speed and reliability, the platform relies on an advanced content delivery architecture, client code optimization, and dynamic communication protocols.
1. Content Delivery Architecture
CDN (Content Delivery Network):
HTTP/2 и HTTP/3 (QUIC):
2. Optimizing Client Load
Code-splitting and dynamic import:
Lazy-load resources:
Service Worker and caching:
3. Minification and packaging of assets
Minification of JavaScript/CSS: Terser, cssnano - removing spaces, comments, shortening variable names.
Bundling: Webpack, Rollup - reduce the number of HTTP requests.
Image optimization: WebP and AVIF instead of PNG/JPEG, using SVG for icons.
Sprite sheets and texture atlases: Reduce the number of render frame loads.
4. Streaming and live games
WebSockets для real-time:
WebRTC for video stream:
MSE (Media Source Extensions):
5. Infrastructure and Deployment
Microservice architecture:
Containerization (Docker, Kubernetes):
CI/CD-pipeline:
6. Monitoring and analytics
Real User Monitoring (RUM): collection of TTFB, FCP, LCP, CLS metrics from real users.
Performance API and Lighthouse: regular scanning of the frontend to find bottlenecks in the load.
Server metrics: API response delay, average CPU/Memory load, WebSocket server response time.
7. Cross-browser and cross-platform support
Polyglots of JS frameworks: React/Vue/Angular with Babel transposition to support older versions of browsers.
Polyfill libraries: core-js, regenerator-runtime for API: Promise, Fetch, Intersection Observer.
Testing on emulators and real devices: BrowserStack, Sauce Labs - checking the starting time and rendering on iOS, Android and desktop.
Conclusion
Instant startup without loading is achieved by a set of measures: geo-distributed CDN, modern HTTP protocols, delayed loading of modules, caching on the client and container infrastructure on the server. Thanks to this, the casino platform guarantees instant access to any games - slots, roulette or live dealers - without installing additional software. This solution provides high speed, reliability and scalability as the audience grows.
Support for instant play means that the player can start any game right in the browser window in a split second - without installation, updates or long download. To ensure this speed and reliability, the platform relies on an advanced content delivery architecture, client code optimization, and dynamic communication protocols.
1. Content Delivery Architecture
CDN (Content Delivery Network):
- Geo-distributed points of presence (PoP) minimize the physical distance to the user.
- Caching static resources (scripts, styles, images) at the edge of the network.
- Automatically switch to the nearest server when load peaks or crashes.
HTTP/2 и HTTP/3 (QUIC):
- Multiplexing requests in one connection without head-of-line blocking.
- Header compression (HPACK/QPACK) and prioritization of critical resources.
- UDP-based HTTP/3 further reduces latency and accelerates packet loss recovery.
2. Optimizing Client Load
Code-splitting and dynamic import:
- Splitting code into modules by game sections.
- Loading the basic framework and engine first, game assets - on demand when choosing a specific slot or ru-lette.
Lazy-load resources:
- Delayed loading of images, sprites and audio files until the moment of real need.
- Intersection Observer API for connecting assets only when the element is visible.
Service Worker and caching:
- Preliminary cache of key files in the install event.
- Background Sync updates without interrupting gameplay.
- Stale-while-revalidate and cache-first strategies for instant access and parallel updating.
3. Minification and packaging of assets
Minification of JavaScript/CSS: Terser, cssnano - removing spaces, comments, shortening variable names.
Bundling: Webpack, Rollup - reduce the number of HTTP requests.
Image optimization: WebP and AVIF instead of PNG/JPEG, using SVG for icons.
Sprite sheets and texture atlases: Reduce the number of render frame loads.
4. Streaming and live games
WebSockets для real-time:
- Permanent connection for instant data exchange (rate ↔ result).
- Ping/pong mechanism for monitoring delay and reconnection.
WebRTC for video stream:
- Peer-to-peer or client-server streaming of live dealers with adaptive bitrate.
- Support for low-latency audio and video channels without plugins.
MSE (Media Source Extensions):
- Buffering and dynamic loading of video segments in the browser.
- Smoothing network jumps and speed drops.
5. Infrastructure and Deployment
Microservice architecture:
- Separate services for authentication, payments, game logic, statistics.
- Scales each component horizontally by load.
Containerization (Docker, Kubernetes):
- Quickly deploy new versions without downtime.
- Health-checks and automatic crash recovery.
CI/CD-pipeline:
- Automatic Builds, Tests and Deploy via Jenkins/GitLab CI/GitHub Actions.
- Canary releases and blue-green depletion for error-free updates.
6. Monitoring and analytics
Real User Monitoring (RUM): collection of TTFB, FCP, LCP, CLS metrics from real users.
Performance API and Lighthouse: regular scanning of the frontend to find bottlenecks in the load.
Server metrics: API response delay, average CPU/Memory load, WebSocket server response time.
