logion-rest-api-core

This library provides the core functionlities that all logion REST-based off-chain services have in common:

• The Authentication controller exposing the REST resources for authentication
• A service maintaining a singleton connection to a logion node
• OpenAPI helpers
• TypeORM helpers
• Dinoloop helpers
• Inversify helpers
• Test helpers
• Various utilities

Usage

Configuring OpenAPI

Below call adds the authentication-related elements to an OpenAPI V3 document.

const spec: OpenAPIV3.Document = ...;
configureOpenApi(spec);

Configure Dinoloop

Below call registers the authentication controller as well as the default application error controller and a JSON response middleware.

const dino: Dino = ...;
configureDinoloop(dino);

Configure Inversify

Below call binds all provided services in the container.

const container: Container = ...;
configureContainer(container);

TypeORM

Simply import the app's data source:

import { appDataSource } from "@logion/rest-api-core";

The returned data source is configured using ormconfig.json file and TYPEORM_* environment variables. This is essentially a re-implementation of the way TypeORM used to be configured before the introduction of the multiple data source feature.

The returned data source is ready to be used with a transaction context. DefaultTransactional method decorator can be used to set a transaction context with default settings. typeorm-transactional's Transactional decorator may also be used safely.
