Scope

This document provides a structured architectural overview of the company microservice, detailing its configuration, data model, authorization logic, business rules, and API design. It has been automatically generated based on the service definition within Mindbricks, ensuring that the information reflects the source of truth used during code generation and deployment.

The document is intended to serve multiple audiences:

  • Service architects can use it to validate design decisions and ensure alignment with broader architectural goals.
  • Developers and maintainers will find it useful for understanding the structure and behavior of the service, facilitating easier debugging, feature extension, and integration with other systems.
  • Stakeholders and reviewers can use it to gain a clear understanding of the service's capabilities and domain logic.

Note for Frontend Developers: While this document is valuable for understanding business logic and data interactions, please refer to the Service API Documentation for endpoint-level specifications and integration details.

Note for Backend Developers: Since the code for this service is automatically generated by Mindbricks, you typically won't need to implement or modify it manually. However, this document is especially valuable when you're building other services—whether within Mindbricks or externally—that need to interact with or depend on this service. It provides a clear reference to the service's data contracts, business rules, and API structure, helping ensure compatibility and correct integration.

Company Service Settings Edit

Handles company profiles, company admin assignments, company following, and posting company updates/news. Enables professionals to follow companies, get updates, and enables admins to manage company presence..

Service Overview

This service is configured to listen for HTTP requests on port 3002, serving both the main API interface and default administrative endpoints.

The following routes are available by default:

  • API Test Interface (API Face): /
  • Swagger Documentation: /swagger
  • Postman Collection Download: /getPostmanCollection
  • Health Checks: /health and /admin/health
  • Current Session Info: /currentuser
  • Favicon: /favicon.ico

The service uses a PostgreSQL database for data storage, with the database name set to linkedin-company-service.

This service is accessible via the following environment-specific URLs:

  • Preview: https://linkedin.prw.mindbricks.com/company-api
  • Staging: https://linkedin-stage.mindbricks.co/company-api
  • Production: https://linkedin.mindbricks.co/company-api

Authentication & Security

  • Login Required: Yes

This service requires user authentication for access. It supports both JWT and RSA-based authentication mechanisms, ensuring secure user sessions and data integrity. If a crud route also is configured to require login, it will check a valid JWT token in the request query/header/bearer/cookie. If the token is valid, it will extract the user information from the token and make the fetched session data available in the request context.

Service Data Objects

The service uses a PostgreSQL database for data storage, with the database name set to linkedin-company-service.

Data deletion is managed using a soft delete strategy. Instead of removing records from the database, they are flagged as inactive by setting the isActive field to false.

Object Name Description Public Access
companyFollower Tracks when a user follows a company to receive updates. Append-only, deletes for unfollow. accessPrivate
companyUpdate A post/news update created by company admin and visible to followers depending on visibility. accessPublic
company Represents a company profile and brand presence/pages on the network. accessPublic
companyAdmin Tracks which users are assigned as admins for a company, allowing them to manage the company page and edits. accessPrivate

companyFollower Data Object

Object Overview

Description: Tracks when a user follows a company to receive updates. Append-only, deletes for unfollow.

This object represents a core data structure within the service and acts as the blueprint for database interaction, API generation, and business logic enforcement. It is defined using the ObjectSettings pattern, which governs its behavior, access control, caching strategy, and integration points with other systems such as Stripe and Redis.

Core Configuration

  • Soft Delete: Enabled — Determines whether records are marked inactive (isActive = false) instead of being physically deleted.
  • Public Access: accessPrivate — If enabled, anonymous users may access this object’s data depending on API-level rules.

Composite Indexes

  • companyFollowerUnique: [companyId, userId] This composite index is defined to optimize query performance for complex queries involving multiple fields.

The index also defines a conflict resolution strategy for duplicate key violations.

When a new record would violate this composite index, the following action will be taken:

On Duplicate: throwError

An error will be thrown, preventing the insertion of conflicting data.

Properties Schema

Property Type Required Description
userId ID Yes FK to auth:user who follows the company.
companyId ID Yes FK to company:company being followed.
followedAt Date Yes Timestamp when user followed company.
  • Required properties are mandatory for creating objects and must be provided in the request body if no default value is set.

Default Values

Default values are automatically assigned to properties when a new object is created, if no value is provided in the request body. Since default values are applied on db level, they should be literal values, not expressions.If you want to use expressions, you can use transposed parameters in any business API to set default values dynamically.

  • userId: '00000000-0000-0000-0000-000000000000'
  • companyId: '00000000-0000-0000-0000-000000000000'
  • followedAt: new Date()

Constant Properties

userId companyId followedAt

Constant properties are defined to be immutable after creation, meaning they cannot be updated or changed once set. They are typically used for properties that should remain constant throughout the object's lifecycle. A property is set to be constant if the Allow Update option is set to false.

Auto Update Properties

userId companyId followedAt

An update crud API created with the option Auto Params enabled will automatically update these properties with the provided values in the request body. If you want to update any property in your own business logic not by user input, you can set the Allow Auto Update option to false. These properties will be added to the update API's body parameters and can be updated by the user if any value is provided in the request body.

Elastic Search Indexing

userId companyId

Properties that are indexed in Elastic Search will be searchable via the Elastic Search API. While all properties are stored in the elastic search index of the data object, only those marked for Elastic Search indexing will be available for search queries.

Database Indexing

userId companyId followedAt

Properties that are indexed in the database will be optimized for query performance, allowing for faster data retrieval. Make a property indexed in the database if you want to use it frequently in query filters or sorting.

Relation Properties

userId companyId

Mindbricks supports relations between data objects, allowing you to define how objects are linked together. You can define relations in the data object properties, which will be used to create foreign key constraints in the database. For complex joins operations, Mindbricks supportsa BFF pattern, where you can view dynamic and static views based on Elastic Search Indexes. Use db level relations for simple one-to-one or one-to-many relationships, and use BFF views for complex joins that require multiple data objects to be joined together.

  • userId: ID Relation to user.id

The target object is a parent object, meaning that the relation is a one-to-many relationship from target to this object.

On Delete: Set Null Required: Yes

  • companyId: ID Relation to company.id

The target object is a parent object, meaning that the relation is a one-to-many relationship from target to this object.

On Delete: Set Null Required: Yes

Filter Properties

userId

Filter properties are used to define parameters that can be used in query filters, allowing for dynamic data retrieval based on user input or predefined criteria. These properties are automatically mapped as API parameters in the listing API's that have "Auto Params" enabled.

  • userId: ID has a filter named userId

companyUpdate Data Object

Object Overview

Description: A post/news update created by company admin and visible to followers depending on visibility.

This object represents a core data structure within the service and acts as the blueprint for database interaction, API generation, and business logic enforcement. It is defined using the ObjectSettings pattern, which governs its behavior, access control, caching strategy, and integration points with other systems such as Stripe and Redis.

Core Configuration

  • Soft Delete: Enabled — Determines whether records are marked inactive (isActive = false) instead of being physically deleted.
  • Public Access: accessPublic — If enabled, anonymous users may access this object’s data depending on API-level rules.

Membership Settings

This data object is configured to support membership-based access control, allowing users to be associated with specific instances of this object. A companyAdmin data object is used to manage membership based acces to this object. The companyAdmin object contains entries that link users to this data object, enabling fine-grained access control based on user membership status. Note that this is not a user management system, but rather a way to associate users with specific instances of this object.

The companyId property in the membership object refers back to this data object, linking the membership entry to this object. The userId property in the membership object refers to the user who holds membership, typically linked to the user's session during authorization checks.

Properties Schema

Property Type Required Description
companyId ID Yes FK to company whose update this is.
content Text Yes Body/content of the update/news item.
authorUserId ID Yes FK to auth:user who authored the update (must be active admin at time of post).
attachmentUrls String No Array of URLs for update attachments (files, images, links).
visibility Enum Yes Update visibility: public (all) or private (followers only).
  • Required properties are mandatory for creating objects and must be provided in the request body if no default value is set.

Array Properties

attachmentUrls

Array properties can hold multiple values and are indicated by the [] suffix in their type. Avoid using arrays in properties that are used for relations, as they will not work correctly. Note that using connection objects instead of arrays is recommended for relations, as they provide better performance and flexibility.

Default Values

Default values are automatically assigned to properties when a new object is created, if no value is provided in the request body. Since default values are applied on db level, they should be literal values, not expressions.If you want to use expressions, you can use transposed parameters in any business API to set default values dynamically.

  • companyId: '00000000-0000-0000-0000-000000000000'
  • content: 'text'
  • authorUserId: '00000000-0000-0000-0000-000000000000'
  • visibility: public

Constant Properties

companyId authorUserId

Constant properties are defined to be immutable after creation, meaning they cannot be updated or changed once set. They are typically used for properties that should remain constant throughout the object's lifecycle. A property is set to be constant if the Allow Update option is set to false.

Auto Update Properties

companyId content authorUserId attachmentUrls visibility

An update crud API created with the option Auto Params enabled will automatically update these properties with the provided values in the request body. If you want to update any property in your own business logic not by user input, you can set the Allow Auto Update option to false. These properties will be added to the update API's body parameters and can be updated by the user if any value is provided in the request body.

Enum Properties

Enum properties are defined with a set of allowed values, ensuring that only valid options can be assigned to them. The enum options value will be stored as strings in the database, but when a data object is created an addtional property with the same name plus an idx suffix will be created, which will hold the index of the selected enum option. You can use the index property to sort by the enum value or when your enum options represent a sequence of values.

  • visibility: [public, private]
