Optimization Strategies
Learn how to optimize Atomix layout components for maximum performance. From basic optimization techniques to advanced performance monitoring and troubleshooting.
Layout performance is crucial for user experience. Poor layout performance can cause several issues:
Visual instability as content moves
Delayed paint and layout operations
Inconsistent frame rates
Accumulating DOM nodes and event listeners
Unnecessary CSS and JavaScript
Monitor these Core Web Vitals to measure and improve layout performance:
Visual stability score
Time to first rendered content
Time to largest content element
Time until page is fully interactive
Avoid expensive calculations on every render. Use memoization to optimize column size calculations.
1// ❌ Avoid: Expensive calculations on every render
2function SlowGrid({ items }) {
3 const getColumnSize = (index) => {
4 // Complex calculation on every render
5 return Math.floor(12 / Math.sqrt(items.length)) || 1;
6 };
7
8 return (
9 <Grid>
10 {items.map((item, index) => (
11 <GridCol key={item.id} md={getColumnSize(index)}>
12 {item.content}
13 </GridCol>
14 ))}
15 </Grid>
16 );
17}
18
19// ✅ Better: Memoized calculations
20import { useMemo } from 'react';
21
22function OptimizedGrid({ items }) {
23 const columnSize = useMemo(() => {
24 return Math.floor(12 / Math.sqrt(items.length)) || 1;
25 }, [items.length]);
26
27 return (
28 <Grid>
29 {items.map((item) => (
30 <GridCol key={item.id} md={columnSize}>
31 {item.content}
32 </GridCol>
33 ))}
34 </Grid>
35 );
36}Strategies to reduce Cumulative Layout Shift (CLS):
1<div className="u-ratio u-ratio-16x9">
2 <img
3 src="image.jpg"
4 alt="Description"
5 className="u-ratio-item"
6 loading="lazy"
7 />
8</div>For large datasets, use virtualization to render only visible items:
1import { VirtualizedGrid } from '@shohojdhara/atomix';
2
3<VirtualizedGrid
4 items={largeDataset}
5 itemHeight={200}
6 renderItem={(item) => (
7 <GridCol md={4}>
8 <Card>{item.content}</Card>
9 </GridCol>
10 )}
11/>Inline critical CSS for above-the-fold content to improve First Contentful Paint (FCP):
1<style>
2 /* Inline critical layout styles */
3 .container {
4 max-width: 1200px;
5 margin: 0 auto;
6 }
7 .Grid {
8 display: flex;
9 flex-wrap: wrap;
10 }
11 .col {
12 flex: 1;
13 padding: 0.75rem;
14 }
15</style>Use CSS containment to isolate expensive layout calculations and improve rendering performance:
1.expensive-component {
2 contain: layout style paint;
3}

5/* Benefits:
6 * - Isolates layout calculations
7 * - Prevents style recalculation
8 * - Improves paint performance
9 * - Reduces layout thrashing
10 */Memoize expensive calculations and component renders to avoid unnecessary recalculations.
Use proper image formats, lazy loading, and aspect ratios to prevent layout shifts.
For large datasets, use virtualization to render only visible items.
Regularly monitor Core Web Vitals to identify and fix performance issues.
