EdgeJS

Cache key normalization
Cache splitting
GraphQL caching
Multiple backends on one domain
Iterative migration away from legacy backend

CDN config that you’ll actually use

For the first time ever, control the edge in JavaScript in your router to ensure high cache hit rates for your page URLs. EdgeJS is convenient, expressive, and reliable because it goes through the local development → peer review → QA → Release cycle like the rest of your code does.

CDN config that you’ll actually use

For the first time ever, control the edge in JavaScript in your router to ensure high cache hit rates for your page URLs. CDN-as-JavaScript is convenient, expressive, and reliable because it goes through the PR => Review => Test => Release cycle like the rest of your code does.

Stream data to the browser before it’s needed

EdgeJS service worker intelligently fetches your dynamic pages before your visitor taps on a link. Our network and monitoring tools ensure that that dynamic data is cached at least 95% of the time, shielding your database from the extra requests created by prefetching.

Develop CDN rules locally

Run CDN rules and other edge logic on developers’ local machines. Never deploy to staging just to test your CDN rules. This is especially useful when developing split tests and running multiple backends.

Cache clearing on steroids

Clear the cache globally in seconds for a specific URL, by regex, by surrogate key, or for the entire site. Clear cache via console, API, or CLI. And coming soon, we will listen to changes in your database and automatically clear only the objects that have changed. Everything about your site's data is under your control with EdgeJS.

Enhance your CDN

Layer0's EdgeJS can replace everything you get from your current CDN and has all the web security features you need at the edge. Or keep your CDN, Layer0's EdgeJS can sit behind or alongside it—it won’t slow down your sub-second website.
