Notes: ## Introduction - Web rendering includes steps from user opening a site to full page display - Key steps: DNS lookup, HTTP request, HTML parsing, CSS parsing, JavaScript execution - Different rendering approaches exist due to varied site requirements ## Key Metrics 1. Time to First Byte (TTFB): Time between clicking a link and first content byte loading 2. First Contentful Paint (FCP): Time when any part of page content is rendered 3. Largest Contentful Paint (LCP): Time until largest image/text block is rendered 4. Total Blocking Time (TBT): Measures main thread blocking during page load ## Business Considerations - Types of applications: - B2B (Business-to-Business) - B2C (Business-to-Consumer) - Internal Tools - Profit Centers vs. Cost Centers ## Rendering Patterns ### 1. Server-Side Rendering (SSR) - Types: Dynamic SSR, Static Site Generation (SSG) - Advantages: - Fast time to content - Good SEO - Improved Core Web Vitals - Disadvantages: - Full page reloads - Increased server load - More complex server configuration ### 2. Static Site Generation (SSG) - Generates static HTML files during build time - Advantages: - Fast load times - Reduced server load - Good SEO - Disadvantages: - Limited to static content - Frequent rebuilds for content updates ### 3. Client-Side Rendering (CSR) - Renders content in the browser using JavaScript - Advantages: - Smooth user experience - Easier development and maintenance - Reduced server load - Disadvantages: - Poor SEO (if not mitigated) - Slower initial load - Performance issues on low-power devices ### 4. Hydration - Process of making server-side rendered static HTML interactive - Types: - Full Hydration - Partial/Selective Hydration - Progressive Hydration - Island Architecture - Challenges: - Uncanny Valley effect - "One app for the price of two" problem ### 5. Resumability - Recovers application state without re-executing components on client-side - Implemented in Qwik framework - Solves "one app for the price of two" problem ### 6. Pre-rendering - Creates SEO-friendly single-page applications - Serves different versions for users and web crawlers - Advantages: - Good SEO for SPAs - Smooth single-page experience - Disadvantages: - More complex setup - Higher server load ## Advanced Techniques 1. Code Splitting 2. Preloading 3. Lazy Loading 4. Application Shell Architecture 5. Trimorphic Rendering (combines SSR, CSR, and Service Workers) ## Choosing the Right Approach Consider: - Website vs. Web Application - Static vs. Dynamic content - SEO requirements - Initial loading time importance - UI responsiveness needs - Budget constraints - Offline support requirements Use the decision tree provided in the lecture to guide your choice. ## Use Cases 1. Social Network: SSR with Hydration (Progressive/Island Architecture) 2. Dashboard: Client-Side Rendering with optimization techniques 3. Marketplace (e.g., Amazon): SSR or SSR with Hydration Remember to always consider specific project requirements and constraints when choosing a rendering pattern.
brother i cannot express my love ♥for watching and gaining so much of knowledge from this YT channel, eagerly wait for your videos tbh. Lots of love and keep bringing more content
thanks a lot man, really i owe you alot , the way you are providing content is very usefull for senior and lead level and manager level thank you once again keep going

## Introduction
- Web rendering includes steps from user opening a site to full page display
- Key steps: DNS lookup, HTTP request, HTML parsing, CSS parsing, JavaScript execution
- Different rendering approaches exist due to varied site requirements
## Key Metrics
1. Time to First Byte (TTFB): Time between clicking a link and first content byte loading
2. First Contentful Paint (FCP): Time when any part of page content is rendered
3. Largest Contentful Paint (LCP): Time until largest image/text block is rendered
4. Total Blocking Time (TBT): Measures main thread blocking during page load
## Business Considerations
- Types of applications:
- B2B (Business-to-Business)
- B2C (Business-to-Consumer)
- Internal Tools
- Profit Centers vs. Cost Centers
## Rendering Patterns
### 1. Server-Side Rendering (SSR)
- Types: Dynamic SSR, Static Site Generation (SSG)
- Advantages:
- Fast time to content
- Good SEO
- Improved Core Web Vitals
- Disadvantages:
- Full page reloads
- Increased server load
- More complex server configuration
### 2. Static Site Generation (SSG)
- Generates static HTML files during build time
- Advantages:
- Fast load times
- Reduced server load
- Good SEO
- Disadvantages:
- Limited to static content
- Frequent rebuilds for content updates
### 3. Client-Side Rendering (CSR)
- Renders content in the browser using JavaScript
- Advantages:
- Smooth user experience
- Easier development and maintenance
- Reduced server load
- Disadvantages:
- Poor SEO (if not mitigated)
- Slower initial load
- Performance issues on low-power devices
### 4. Hydration
- Process of making server-side rendered static HTML interactive
- Types:
- Full Hydration
- Partial/Selective Hydration
- Progressive Hydration
- Island Architecture
- Challenges:
- Uncanny Valley effect
- "One app for the price of two" problem
### 5. Resumability
- Recovers application state without re-executing components on client-side
- Implemented in Qwik framework
- Solves "one app for the price of two" problem
### 6. Pre-rendering
- Creates SEO-friendly single-page applications
- Serves different versions for users and web crawlers
- Advantages:
- Good SEO for SPAs
- Smooth single-page experience
- Disadvantages:
- More complex setup
- Higher server load
## Advanced Techniques
1. Code Splitting
2. Preloading
3. Lazy Loading
4. Application Shell Architecture
5. Trimorphic Rendering (combines SSR, CSR, and Service Workers)
## Choosing the Right Approach
Consider:
- Website vs. Web Application
- Static vs. Dynamic content
- SEO requirements
- Initial loading time importance
- UI responsiveness needs
- Budget constraints
- Offline support requirements
Use the decision tree provided in the lecture to guide your choice.
## Use Cases
1. Social Network: SSR with Hydration (Progressive/Island Architecture)
2. Dashboard: Client-Side Rendering with optimization techniques
3. Marketplace (e.g., Amazon): SSR or SSR with Hydration
Remember to always consider specific project requirements and constraints when choosing a rendering pattern.
Easily the best FE systems design content creator, thank you!
Hello Dmitriy, Love 💖from Tamilnadu and Tamil Eelam. Thanks for saving me with helpful contents.
Dang, This is gold! Going to binge watch all these this weekend!
About to start reactjs and i found the goldmine I guess. as soon as I complete reactjs ill study from you. keep them coming
You gave the great explanation of rendering patterns and I am fortunate I found this channel in recommendations
Your explanation is clear as crystal! Thank you❤
brother i cannot express my love ♥for watching and gaining so much of knowledge from this YT channel, eagerly wait for your videos tbh. Lots of love and keep bringing more content
thanks a lot man, really i owe you alot , the way you are providing content is very usefull for senior and lead level and manager level thank you once again keep going
Thank you! Very useful. Important topic and unique content
Superb content.. thanks for clearing the gaps..🎉
Thank you! I've been waiting for it ❤
thank you , great video
great video
Gem channel.
subed man. Thank you :)
Great explanation. Is it possible to get the slides of the video
Great video, thank you. Just one small advice, in your next videos speak slower ❤
can you please share the slides that you have used in the video.
Thanks for free knowledge.
can you provide a link for the slides please?, i want to review them later
in 17:40 I think the build-time definition is not quite right. build time is the process before the project is served to the server not to the client.
Is there a way to filter out the breathing noise? It's hurting my ears. :'(
