Core Utilities Overview

The Core Utility (`util-core`) is a standard library of utility functions designed to simplify and accelerate Rule development on the Fluent Commerce platform. It provides a foundational set of helper classes that address common development challenges - such as safely handling event attributes, retrieving and converting settings, logging consistently, and minimizing boilerplate code when forwarding events or querying data.PrerequisitesThese articles assumes you're familiar with:

Java
Maven
JUnit

Create Comment

The `createComment` Mutation allows the creation of a Comment against a known Entity.
PrerequisitesSpecific Permissions are required for creating Comments:

`COMMENT_CREATE`
`COMMENT_VIEW`

Create or Update Sourcing Profile

The `createSourcingProfile` mutation creates a Sourcing Profile (or its newer version, i.e., updates) for a Retailer:

If the provided `ref` is unique, it creates the first version with `ACTIVE` status
If a `SourcingProfile` with the same `ref` already exists, it creates a new version with `DRAFT` status

Dynamic Mutations

`DynamicUpdateMutation` automatically derives the correct update Mutation for the primary Entity based on the `RulesetContext` and then performs the update on one or more fields.

Dynamic Pagination

`DynamicConnectionQuery` automatically derives the Connection fields (arrays) for the primary Entity based on the `RulesetContext` and can dynamically load all connection items, with pagination handled internally.

Dynamic Queries and Utils

Edited 91 days ago

`DynamicEntityQuery`, with the help of the `DynamicUtils` class, automatically derives the correct GraphQL query operation for the primary Entity from the `RulesetContext`. It dynamically retrieves fields related to that Entity, removing the need for pre-compiled queries while preserving type safety and performance.

Dynamic Utilities Overview

Edited 92 days ago

The `util-dynamic` library is a collection of utility functions that allow you to generate GraphQL queries and mutations at runtime. This enables the creation of highly configurable and reusable rules that can adapt to different needs without requiring code changes.PrerequisitesThese articles assumes you're familiar with:

Java
Maven
JUnit

Event Utilities

The `EventUtils` class in the `util-core` bundle provides a set of essential helper methods to simplify event creation, modification, and forwarding.

The Responsive Sourcing Framework is a configurable, scalable alternative to custom Workflows and Rules for managing sourcing strategies. You’ll learn how to define and optimize sourcing logic using Sourcing Profiles, Strategies, Conditions, and Criteria. The Framework empowers both technical and business users with faster implementation, greater control, and transparency into how sourcing decisions are made and why.

Rule Context Generator

The `RuleContextGenerator` is the underlying class that the `RuleExecutor` and `WorkflowExecutor` use to construct a mock `Context` for your tests. While you will most often interact with it through the executors, you can also use it directly to manually create a `Context` object.This is particularly useful when you are unit testing a helper or utility class that requires a `Context` object as a parameter, but you don't need to execute a full rule.

Rule Executor

The `RuleExecutor` is the primary tool in the `util-test` library for unit testing a single rule in isolation. It provides a builder-style interface for setting up a mock `Context`, executing your rule's `run` method, and asserting the results.

Rule Utilities

The `RuleUtils` class in the `util-core` bundle provides helper methods to streamline the process of retrieving and validating Rule properties. Using these utilities helps ensure that your Rules are configured correctly and reduces the risk of runtime errors caused by missing or invalid parameters.

Search Sourcing Profiles

The `sourcingProfiles` query retrieves existing Sourcing Profiles. It supports multiple filters and pagination.

Setting Utilities

The `SettingUtils` class in the `util-core` bundle provides a robust set of tools for retrieving configuration settings from the Fluent Commerce API. A key feature of this utility is that it automatically respects the platform's setting hierarchy, ensuring that the most specific setting value is always returned.
