How PIXGet Streamlines Your Image Workflow

Getting Started with PIXGet — Installation & TipsPIXGet is a lightweight image retrieval library designed to simplify fetching, caching, and displaying images in web and mobile applications. This guide walks you through installation, basic usage, configuration options, performance tips, and troubleshooting so you can integrate PIXGet quickly and reliably.

---

What PIXGet does (brief overview)

PIXGet fetches images efficiently, handles caching, and exposes simple APIs for transformation and lazy loading. It supports both browser and Node environments and integrates with popular frameworks (React, Vue, Angular) as well as native mobile bridges.

---

Prerequisites

• Basic knowledge of JavaScript/TypeScript.
• Node.js >= 14 for development/build tools (if using bundlers or server-side rendering).
• A modern web browser for client-side usage or a compatible mobile runtime for native bridges.

---

Installation

PIXGet is available via npm and CDN.

• npm (recommended for most projects):

npm install pixget 

• Yarn:

yarn add pixget 

• CDN (quick test or simple pages):

<script src="https://cdn.example.com/pixget/latest/pixget.min.js"></script> 

After installing, import PIXGet into your project:

// ES module import PIXGet from 'pixget'; // CommonJS const PIXGet = require('pixget'); 

---

Basic usage

The simplest pattern is to create a PIXGet client and request an image URL:

const client = new PIXGet(); async function loadImage(url) {   try {     const result = await client.get(url);     // result.data is a Blob (browser) or Buffer (Node)     const objectUrl = URL.createObjectURL(result.data);     document.getElementById('img').src = objectUrl;   } catch (err) {     console.error('PIXGet error:', err);   } } 

PIXGet supports requesting transformations declaratively:

const transformed = await client.get(url, {   resize: { width: 800, height: 600 },   format: 'webp',   quality: 80 }); 

---

Integration with frameworks

React

Use PIXGet inside components and hooks. Example with a custom hook:

import { useEffect, useState } from 'react'; import PIXGet from 'pixget'; const client = new PIXGet(); function usePixImage(url, opts) {   const [src, setSrc] = useState(null);   useEffect(() => {     let canceled = false;     client.get(url, opts).then(res => {       if (!canceled) setSrc(URL.createObjectURL(res.data));     }).catch(() => {});     return () => { canceled = true; };   }, [url, JSON.stringify(opts)]);   return src; } 

Vue

Provide PIXGet via plugin or import per-component. Example:

<template>   <img :src="src" alt="pixget image"/> </template> <script> import PIXGet from 'pixget'; const client = new PIXGet(); export default {   props: ['url'],   data: () => ({ src: '' }),   async mounted() {     const res = await client.get(this.url);     this.src = URL.createObjectURL(res.data);   } } </script> 

---

Configuration options

Common options when calling client.get(url, options):

• cache: ‘memory’ | ‘disk’ | ‘none’ — choose caching layer.
• ttl: milliseconds — time-to-live for cached items.
• resize: { width, height } — server/client side resize hint.
• format: ‘jpeg’ | ‘png’ | ‘webp’ — desired output format.
• quality: 0–100 — lossy compression quality.
• placeholder: boolean/string — use a low-res placeholder or SVG.
• retry: { attempts, delay } — retry policy for transient errors.

Example:

client.get(url, {   cache: 'memory',   ttl: 1000 * 60 * 10,   resize: { width: 1200 },   format: 'webp',   quality: 85 }); 

---

Lazy loading & placeholders

Combine IntersectionObserver with PIXGet for efficient lazy loading:

const observer = new IntersectionObserver(entries => {   entries.forEach(entry => {     if (entry.isIntersecting) {       loadImage(entry.target.dataset.src);       observer.unobserve(entry.target);     }   }); }); document.querySelectorAll('img[data-src]').forEach(img => {   observer.observe(img); }); 

Use a tiny blurred placeholder initially (either generated by PIXGet or a base64-encoded SVG) and swap it when the full image loads.

---

Caching strategies

• Memory cache for short-lived items (fast lookups).
• Disk cache for larger or persistent assets (service workers or IndexedDB in browsers).
• CDN + client cache: serve transformed images from CDN to reduce origin load.

For service-worker caching:

self.addEventListener('fetch', event => {   const url = new URL(event.request.url);   if (url.pathname.startsWith('/images/')) {     event.respondWith(caches.open('pixget-images').then(cache =>       cache.match(event.request).then(resp =>         resp || fetch(event.request).then(r => { cache.put(event.request, r.clone()); return r; })       )     ));   } }); 

---

Performance tips

• Prefer modern formats (WebP/AVIF) for smaller payloads.
• Resize images server-side to required display size.
• Use responsive srcset/picture elements for different viewport sizes.
• Enable HTTP/2 or HTTP/3 to improve multiple asset loading.
• Use CDN edge caching for transformed images.

---

Error handling & retries

Handle network and decoding errors gracefully:

try {   const res = await client.get(url, { retry: { attempts: 3, delay: 500 } }); } catch (err) {   // show fallback image } 

Log errors with context (URL, options, timestamp) to help debugging.

---

Security considerations

• Validate external URLs to avoid SSRF.
• Sanitize any transformation parameters if they’re user-provided.
• Limit allowed formats and sizes to prevent resource exhaustion.

---

Troubleshooting

• Blank image: check response blob type and URL.createObjectURL lifecycle.
• Slow loads: verify cache headers and CDN configuration.
• Corrupted image: check transformation pipeline and source integrity.

---

Example full workflow (summary)

1. Install PIXGet.
2. Create client and choose cache strategy.
3. Integrate with your UI (lazy loading + placeholder).
4. Serve transformed images via CDN.
5. Monitor performance and errors; tune options.

If you want, I can: provide a ready-to-use React component using PIXGet; generate service-worker code tuned for your needs; or write an integration guide for a specific backend/CDN.
