Image optimization service

Development

• Use current node version from .nvmrc file $> nvm install, or make sure you've at least Node 12.x installed
• Next run $> npm install
• Start Dev server with $> npm run dev
• Open the sample HTML example in browser. examples/frontend/simple-resize.html
• For Production ready build: $> npm run build && npm start

API

• In HTML; use

<img src="http://image-optimizer-service/widthxheight/https://path-to-hosted-image.jpg" >

• HTTP request:

$> curl --request GET -sL \
     --url 'http://image-optimizer-service/widthxheight/https://path-to-hosted-image.jpg' \
     --output './path/to/file'

Roadmap

• NodeJS API-first microservice; created using personal template repository
• Health check endpoints
• CI checks for build
• Happy scenario image fetching and resizing API using Sharp
• Dockerfile
• Added security layer (with URL tokens and/or hashing)
• Usage patterns: (e.g with CDN, with caching layer and proxy-server, serverless approach)
• Telemetry support
• Logging Middleware
• API versioning
• Deployment descriptors
• Continuous Deployments support

Caveats

TBD

On the shoulders of Giants

This NodeJS implementation is far from done. It's inspired by years of working and tinkering with other solutions such as:

• thumbor
• imgproxy
• ImageMagick
