@janiscommerce/api-session

api-session

A session manager for APIs

Installation

npm install @janiscommerce/api-session

API

The package exports two classes ApiSession and ApiSessionError.

ApiSession

• constructor(authorizationData) Receives an object with the following (optional) properties: { userId, clientId, clientCode, profileId, permissions }

ApiSession has the following getters:

• userId {string} The ID of the user or undefined in case there is no user
• clientId {string} The ID of the client or undefined in case there is no client
• clientCode {string} The code of the client or undefined in case there is no client
• profileId {string} The ID of the profile or undefined in case there is no profile
• permissions {array} The permission keys or undefined in case there are no permissions associated
• async client {object} Resolves to the client object with the getInstance() method injected. The properties depend on your client internal structure. The client is injected with a getInstance() method to propagate the session to other instances.

Settings

The package has some configurable parameters, which are loaded using @janiscommerce/settings

Setting	Description	Default value
clients.databaseKey	Indicates the DB key to use to fetch a session's client	'core'
clients.table	Indicates the table to use to fetch a session's client	'clients'
clients.identifierField	Indicates the field to use as a filter to fetch a session's client	'code'

Usage

const { ApiSession, ApiSessionError } = require('@janiscommerce/api-session');

	clientId: 2,
	clientCode: 'janis',
	profileId: 5,
	permissions: [
		'catalog:product:read',
		'catalog:product:write'
	]
});

console.log(`Session created for user ${session.userId} on client ${session.clientCode}.`);

const sessionInjectedModel = session.getSessionInstance(SomeModel);

console.log(`Session is propagated for user ${sessionInjectedModel.session.userId} on client ${sessionInjectedModel.session.clientCode}.`);

const client = await sessionInjectedModel.client;
