Pika
Accelerate web performance with ESM-powered tools and services
About Pika
Pika is a mission-driven project dedicated to making the web 90% faster by leveraging ES module syntax (ESM). By enabling efficient module loading, caching, and sharing across sites, Pika aims to reduce redundant downloads of third-party libraries like React, Lodash, and jQuery. Explore tools like Snowpack for faster builds and Skypack for direct npm package loading in the browser.
FAQ
ESM (ES module syntax) is JavaScript's native module system, introduced in 2015. It uses a more compact import/export syntax that results in smaller, faster JavaScript. ESM allows modules to be indexed and cached universally, meaning only changed files need to be fetched, improving performance by avoiding full bundle downloads.
ESM enables cross-origin caching, so third-party libraries (like React or Lodash) can be shared across sites. This means users may already have dependencies cached from other sites, reducing redundant downloads and improving load times significantly.
There are still open questions, such as cache fingerprinting risks, web packaging for multi-origin sharing, and security considerations. While progress is being made, full implementation may take a few more years.
You can follow Pika on Twitter or support them on Patreon to help advance ESM-focused tools and services for faster web development.
