@universal-packages/express-controllers-session NP

Express controllers session

Express session for universal controllers.

Install

npm install @universal-packages/express-controllers-session

npm install express
npm install @universal-packages/express-controllers

Global middleware

By installing this package a global middleware is going to be loaded automatically by the ExpressControllers.

Global methods

`initialize([options: ExpressSessionOptions])`

Set up the global middleware session options before loading the ExpressControllers.

import { initialize } from '@universal-packages/express-controllers-session'
import { RedisEngine } from '@universal-packages/universal-token-registry-redis'

initialize({ engine: 'redis', engineOptions: { host: 'localhost' }  })

await expressControllers.prepare()

Options

Same options as express-session.

Decorators

`@AuthenticateAction()`

You can use @AuthenticateAction to quickly end request when no session is present at action level.

import { BaseController, Controller, Get, Post } from '@universal-packages/express-controllers'
import { AuthenticateAction } from '@universal-packages/express-controllers-session'

@Controller('good')
export default class GoodController extends BaseController {
  @Get()
  @AuthenticateAction()
  async action() {
    this.request.parameters
  }
}

`@AuthenticateController()`

You can use @AuthenticateController to quickly end request when no session is present for every action in a controller.

import { BaseController, Controller, Get, Post } from '@universal-packages/express-controllers'
import { AuthenticateController } from '@universal-packages/express-controllers-session'

@Controller('good')
@AuthenticateController()
export default class GoodController extends BaseController {
  @Get()
  async action() {
    this.request.parameters
  }
}

Create your own

Creating your own decorator enables you to not only end the request but also make the request richer with additional data.

import { ActionUse, ControllerUse } from '@universal-packages/express-controllers'

async function authenticateRequest(request, response, next) {
  if (request.session.authenticated) {
    request.currentUser = await User.findById(request.session.authenticatableId)

    next()
  } else {
    response.status(401).end()
  }
}

export function AuthenticateAction() {
  return ActionUse(authenticateRequest)
}

export function AuthenticateController() {
  return ControllerUse(authenticateRequest)
}
