The opinionated engine for extension developers who want to skip the boilerplate and ship faster.
Just link your project directory to the Epos and start coding. It manages the runtime environment and live-reloading without a manual build step.
State management that feels like magic. Modify a JavaScript object, and the changes are automatically persisted and synchronized across all extension contexts.
10x better than standard APIs. Forget tracking Tab IDs or proxying messages. With epos.bus, you send a message once and it’s delivered to every listener across your entire extension ecosystem—no matter where they are.
Access extension capabilities from anywhere. Epos wraps standard Chrome APIs so they can be called from content scripts or web pages without the usual restrictions.
Simplified cross-context storage. Epos wraps IndexedDB with a straightforward key-value API that works seamlessly across all extension contexts—no setup required.
