Create Backend Module

Prerequisites

• Entity Name: CamelCase (e.g., MalwareAnalysis).
• Entity Type: Constant (e.g., ENTITY_TYPE_MALWARE_ANALYSIS).
• Parent/Category: e.g., ABSTRACT_STIX_DOMAIN_OBJECT.

Procedure

Step 1 — Create Directory Structure

Create opencti-platform/opencti-graphql/src/modules/<entityName>.

Step 2 — Create Schema File (<name>.graphql)

Define the Input, Type, Queries, and Mutations.

Step 3 — Create Type Definition (<name>-types.ts)

Define TypeScript interfaces for StixObject, StoreEntity, and internal representations. Export the ENTITY_TYPE_X constant here.

Step 4 — Create Converter (<name>-converter.ts)

Implement convert<Name>ToStix function to map StoreEntity to StixObject.

Step 5 — Create Domain Logic (<name>-domain.ts)

Implement CRUD functions: findAll, findById, add<Name>, delete<Name>. Use listEntities and createEntity from database/middleware.

Step 6 — Create Resolvers (<name>-resolvers.ts)

Map the GraphQL Query/Mutation fields to the functions in <name>-domain.ts.

Step 7 — Create Module Definition (<name>.ts)

Implement ModuleDefinition interface. Define attributes, relations, and register the definition using registerDefinition. If the module is behind a feature flag, set featureFlag: <FLAG_CONSTANT> on each attribute and nested mapping — see the add-feature-flag skill.

Step 8a — Create GraphQL Registration File (<name>-graphql.ts)

Create a <name>-graphql.ts file in the module folder that imports the module schema/resolvers and calls registerGraphqlSchema(...).

Step 8b — Register Module in src/modules/index.ts

Add two distinct imports in src/modules/index.ts:

1. In the region registration modules section, import ./<entityName>/<entityName> (module definition registration).
2. In the region graphql registration section, import ./<entityName>/<entityName>-graphql (GraphQL endpoint registration).

Step 8c — Update GraphQL Unions (if applicable)

If the entity belongs to a STIX union type (e.g., StixObject, StixDomainObject), add it to the relevant unions in src/schema/opencti.graphql.

Step 8d — Regenerate Schema Types

Run yarn build:schema to regenerate TypeScript types from the updated schema.
