@browser-compat/core

Core types, manifest validation, and compatibility decisions for the Browser Compat toolkit.

Browser Compat helps applications generate browser compatibility manifests from their own browserslist targets, check those manifests in CI, and use the result at runtime through small framework adapters.

What This Package Does

@browser-compat/core contains the shared logic used by the CLI, runtime, and framework adapters:

• compatibility manifest types
• manifest creation and validation
• runtime feature extraction
• manifest freshness checks against current browser targets
• compatibility status decisions

This package has no DOM or React dependency.

Most applications use it indirectly through @browser-compat/cli, @browser-compat/runtime, or @browser-compat/react.

Installation

npm install @browser-compat/core

Usage

import { validateCompatManifest } from "@browser-compat/core";

const result = validateCompatManifest(manifest);

if (!result.ok) {
  console.error(result.errors);
}
