📦 Install

Add wordpress_client to your pubspec.yaml:

dependencies:
  wordpress_client: ^9.2.0

Then run flutter pub get or dart pub get.

🔧 Quick start

Import and initialize:

import 'package:wordpress_client/wordpress_client.dart';

final client = WordpressClient.forSite(
  siteUrl: Uri.parse('https://example.com'),
  // or: baseUrl via WordpressClient(baseUrl: Uri.parse('.../wp-json/wp/v2'))
);

🧩 GraphQL (WPGraphQL)

If your site uses the WPGraphQL plugin (canonical), you can send GraphQL operations using the same client and auth.

final client = WordpressClient.forSite(
  siteUrl: Uri.parse('https://example.com'),
  bootstrapper: (b) => b
    .withDefaultAuthorization(
      WordpressAuth.appPassword(user: 'user', appPassword: 'xxxx-xxxx'),
    )
    .build(),
);

// Auto-resolves https://example.com/graphql from the REST base.
final result = await client.graphql.query<List<Map<String, dynamic>>>(
  document: '''
    query Posts($limit: Int!) {
      posts(first: $limit) {
        nodes { id title }
      }
    }
  ''',
  variables: { 'limit': 5 },
  parseData: (data) {
    final nodes = (data['posts']?['nodes'] as List<dynamic>? ?? const [])
        .cast<Map<String, dynamic>>();
    return nodes;
  },
  requireAuth: false, // set true for restricted queries/mutations
);

switch (result) {
  case WordpressSuccessResponse():
    print(result.data);
  case WordpressFailureResponse():
    print('GraphQL error: ${result.error}');
}

// Custom endpoint path if your site exposes a different GraphQL path
client.graphql.setEndpointPath('/custom-graphql');

Add an auth quickly (helpers available):

final client = WordpressClient.forSite(
  siteUrl: Uri.parse('https://example.com'),
  bootstrapper: (b) => b
    .withDefaultAuthorization(
      // Built-in helpers
      WordpressAuth.appPassword(user: 'user', appPassword: 'xxxx-xxxx'),
      // or: WordpressAuth.usefulJwt(user: 'user', password: 'pass', device: 'device-id')
      // or: WordpressAuth.basicJwt(user: 'user', password: 'pass')
    )
    .build(),
);

Enable caching via middleware (optional):

final client = WordpressClient(
  baseUrl: Uri.parse('https://example.com/wp-json/wp/v2'),
  bootstrapper: (b) => b
    .withCache(
      ttl: const Duration(minutes: 5),               // optional, default 1 minute
      // cache: MyCustomCacheManager(),              // optional custom store
      // clearOnWrite: false,                        // keep cache after POST/PUT/PATCH/DELETE
    )
    .build(),
);

📝 Notes: applies to GET requests; default store is in-memory (custom stores supported); cache clears by default on writes.

📩 Send a request

Retrieve 20 recent posts in ascending order:

final request = ListPostRequest(
  page: 1,
  perPage: 20,
  order: Order.asc,
);

final response = await client.posts.list(request);

// Dart 3 pattern matching
switch (response) {
  case WordpressSuccessResponse():
    final data = response.data; // List<Post>
    break;
  case WordpressFailureResponse():
    final error = response.error; // WordpressError
    break;
}

// Or use helpers
final posts = (await client.posts.list(ListPostRequest(perPage: 20))).map(
  onSuccess: (s) => s.data,
  onFailure: (f) => <Post>[],
);

final justPosts = (await client.posts.list(ListPostRequest(perPage: 20))).dataOrThrow();

Convenience extensions are available under client.<interface>.extensions for quick lookups and pagination:

final post = await client.posts.extensions.getById(123);
final allMedia = await client.media.extensions.listAll(perPage: 100);
