Sylius honkers.dev Bundle

Plug-and-play Sylius wrapper for the honkers.dev chatbot tool-server. Adds the default tools, data sources and shop widget on top of two lower layers, both pulled in automatically:

• fluffydiscord/honkers-sdk — the framework-agnostic core (tools, data sources, JSON-schema, DTOs).
• fluffydiscord/symfony-honkers-bundle — the vanilla Symfony bundle: the /chatbot/v1 endpoints, security, error format, locale rules, and how to write your own tools and sources.

Read the Symfony bundle README for the tool-server mechanics — this page covers only the Sylius pieces.

Requires PHP ^8.1 and Sylius ^1.14 || ^2.2 || ^2.3.

Requirements

The @alpha on sylius/sylius is only because 2.3 has no stable tag yet (v2.3.0-ALPHA.1); it drops once 2.3 ships stable.

On Sylius 1.14 the widget uses a deprecated hook. 1.14 runs on Symfony 6.4 with no Twig Hooks, so the widget is registered as a sylius_ui template block on sylius.shop.layout.javascripts — the only mechanism 1.14 offers, deprecated in that same release. The container build reports sylius/ui-bundle deprecations for it: expected, not a bug. Endpoints, data sources and catalog notifications are identical on both lines.

Installation

1. Composer

2. Register the bundles

Register both the vanilla Symfony bundle and this Sylius wrapper in config/bundles.php:

3. Routes

The routes are owned by the Symfony bundle. config/routes/fluffy_discord_honkers.yaml:

Keep the endpoints off the shop's _locale prefix — they live under /chatbot/v1 on the shop host.

4. Configuration

The connection and widget config belong to the Symfony bundle. config/packages/fluffy_discord_honkers.yaml:

• backend_url — the honkers.dev origin, used by the widget's backend-url attribute and the catalog notifier. Outside dev, a non-https backend_url is refused and nothing is sent.
• ingest_secret — the shop half of the catalog credential; the backend receives Authorization: Bearer <site_key>.<ingest_secret>.
• widget.cdn_url — where <script src> loads chat.js from. Set it to the Bunny CDN URL the backend publishes to via chatbot:widget:deploy (must equal the backend's BUNNY_CDN_PURGE_URL). Only the script bytes move to the CDN; every API call still goes to backend_url. Empty → falls back to {backend_url}/widget/v1/chat.js.
• widget.enabled — must be a literal boolean; the widget hook is registered at build time.

One site per channel

Map channel codes to site keys when each channel is its own site on the backend. config/packages/fluffy_discord_sylius_honkers.yaml:

• A channel's site key is channel_site_keys[<channel code>], else widget.site_key. An entry is authoritative: a channel mapped to an empty value has no site key and never falls back.
• widget.site_key is optional once channel_site_keys has an entry; it then only serves unmapped channels.
• Keys are channel codes, unnormalized (cz-web stays cz-web); values are strings, literal or %env()%.
• With channel keys set, disabled channels get no catalog notifications and notify-all --channel=<disabled> is refused.
• Empty channel_site_keys (the default) behaves like a single-site shop: channels are never consulted.

5. Security

Add the chatbot_api firewall (see the Symfony bundle README) to config/packages/security.yaml before the Sylius shop firewall — firewalls match in order and shop matches ^/:

Shipped tools

The backend calls these mid-conversation for live data:

• get_order_status — order state, payment and shipping state, tracking codes, item count and total; requires the order number and the customer e-mail (uniform "not found" otherwise).
• get_product_availability — price, currency and stock for up to 20 variant codes; returns a products block for the widget.

Add your own tool → Symfony bundle README.

Shipped sources

The backend pulls these in bulk and ingests them into its retrieval index:

• products — indexable channel products per locale with ProductMetadata (code, name, url, imageUrl, priceMinor, currency, inStock, taxons, taxonNames, attributes); taxons carries taxon codes, taxonNames their names in the requested locale (the backend builds each product's search card from them); the names and main taxon path also live in the document text.
• categories — enabled taxons of the channel tree per locale (code, name, path, url, productCount).
  • Tree = the channel's menu taxon subtree. A taxon is served only when every ancestor below the tree top is enabled, so a disabled branch never leaks its children.
  • The tree top (menu taxon, or tree root when there is none) never disqualifies what is beneath it. Disabling it empties the channel's menu without emptying this source.
  • The menu taxon is served as a category document; a bare tree root is not.
  • A channel with no menu taxon serves the shop's only taxon tree. With several trees it is refused 409 ambiguous_taxon_tree.
  • productCount counts the taxon's whole nested-set subtree, only products passing ProductIndexabilityInterface — so it agrees with the category page (include_all_descendants: true) and the chatbot.
• cms_pages — enabled Monsieur Biz CMS pages per locale (registered only when the plugin is installed).

Every absolute URL a source or tool emits is built on the resolved channel's hostname, not the request host. A read for channel=X returns links on X's domain; only the host is swapped.

• Channel hostname empty → the request host stands in.
• Sylius stores no per-channel scheme or port, so both come from the request context. Set router.request_context.scheme (and host) for notify-all — it runs outside a request and would otherwise emit http://. A shop on a non-standard port carries that port into every channel's URLs.
• imageUrl: a liip_imagine cache resolver in front of web_path memoises the finished absolute URL under a host-less key — the first channel read then feeds its host to every other channel. Keep the chatbot's image filter on a host-agnostic resolver.

Extension points

Both govern the products source; redefine the container alias in services.yaml to replace them:

Add your own source → Symfony bundle README.

Catalog change notifications

These keep the backend's ingested sources fresh. Saving a Product, ProductTranslation, Taxon or TaxonTranslation collects the changed external ids; one POST {backend_url}/api/v1/catalog/changes per (source, locale) is sent on kernel.terminate and ConsoleEvents::TERMINATE, synchronously and one at a time through the SDK's CatalogIngestClient (2 s timeout, 5 s max duration, max 500 ids per request). A failure is logged and swallowed — a dropped notification costs at most one nightly cycle of staleness, never a broken shop request.

What each change announces:

With backend_url or ingest_secret empty, or with neither widget.site_key nor any channel_site_keys entry set, nothing is sent and a warning names the missing key.

Which site receives a (source, locale):

With channel keys set: an enabled channel that serves a changed locale but resolves no key is skipped with a warning; a channel mapped to an empty value is skipped with a debug record; a locale no enabled channel serves is sent nowhere.

Re-announce everything

Re-announces the whole catalog in 500-id batches, pausing 2 s between batches and honouring Retry-After on a 429.

• Pass --channel when no channel can be resolved from the CLI context.
• Without --locale, locales come from the resolved channel, so each channel's catalog is paired with the locales it serves.
• Without channel keys the catalog goes to the widget.site_key site. With channel keys it goes to the resolved channel's site only — a disabled channel or one without a site key aborts the run; run it once per channel.
• --locale must be an ICU-known locale (any spelling); an unknown or unserved locale aborts the run.

Widget

When widget.enabled is true the bundle injects, via the sylius_shop.base#javascripts twig hook on Sylius 2 and the sylius.shop.layout.javascripts template block on Sylius 1.14:

site_key is resolved at render time by the fluffydiscord_chatbot_site_key(fallback) Twig function: the current channel's channel_site_keys entry, else the template's own site_key. The shop's ChannelContextInterface decides the channel; without a resolvable channel the fallback is used. When the resolved key is empty nothing renders — neither script nor element.

Include the template directly with a plain context — the channel key still applies:

widget_cdn_url defaults to {backend_url}/widget/v1/chat.js when widget.cdn_url is unset. The widget talks only to backend_url; it never calls /chatbot/v1 itself.
