@wpkernel/core / CapabilityAdapters

Type Alias: CapabilityAdapters

type CapabilityAdapters = object;

Adapters that capability rules can leverage when evaluating capabilities.

Adapters provide standardized interfaces for capability checking across different systems (WordPress core, REST APIs, custom backends). The capability runtime auto-detects and injects wp.data.select('core').canUser() when available.

Examples

// Using WordPress adapter in capability rule
const capability = defineCapability({
  map: {
    'posts.edit': async (ctx, postId: number) => {
    // ctx.adapters.wp is auto-injected
    const result = await ctx.adapters.wp?.canUser('update', {
      kind: 'postType',
      name: 'post',
      id: postId
    });
    return result ?? false;
  }
});

// Custom adapter for REST endpoint probing
const capability = defineCapability({
  map: rules,
  options: {
    adapters: {
      restProbe: async (key) => {
        const res = await fetch(`/wp-json/acme/v1/capabilities/${key}`);
        return res.ok;
      }
    }
  }
});

// Use in rule
'feature.enabled': async (ctx) => {
  return await ctx.adapters.restProbe?.('advanced-features') ?? false;
}
