Koa 2 usage

[nicolasparada]

How can I use this with Koa 2?
I tried using koa-convert, but because it is injected into this and no ctx, I cannot use it yet...

Well, I could use convert when I'm using it as well too, but almost all endpoints needs validations, so I wanna avoid using convert all over the place.

I mean, right now I'm doing it like so:
router.js

import convert from 'koa-convert'
import jsonBody from 'koa-json-body'
import validation from 'koa-validation'
import * as TokensController from './controllers/tokens'
/* ... */
router.use(jsonBody())
router.use(convert(validation()))

router.post('/tokens', ...TokensController.store)

controllers/tokens.js

import convert from 'koa-convert'

export const store = [
  convert(function *(next) {
    yield this.validateBody({
      email: 'required|email',
      password: 'required|minLength:6'
    }, null, {
      before: {
        email: 'trim|lowercase'
      }
    })

    if(this.validationErrors)
      this.throw(this.validationErrors, 422)
    else
      yield next
  }),

  function(ctx) {
    ctx.body = { message: 'POST /tokens' }
  }
]

---

While, it should be:
router.js

import jsonBody from 'koa-json-body'
import validation from 'koa-validation'
import * as TokensController from './controllers/tokens'
/* ... */
router.use(jsonBody())
router.use(validation())

router.post('/tokens', ...TokensController.store)

controllers/tokens.js

export const store = [
  async function(ctx, next) {
    await ctx.validateBody({
      email: 'required|email',
      password: 'required|minLength:6'
    }, null, {
      before: {
        email: 'trim|lowercase'
      }
    })

    if(ctx.validationErrors)
      ctx.throw(ctx.validationErrors, 422)
    else
      await next()
  },

  function(ctx) {
    ctx.body = { message: 'POST /tokens' }
  }
]

It would also be nice to see some example with async/await so people not interested in generators don't have to reach to issues :)

I guess this module has joined the rest at the bottom of an ocean? No response for over a year makes me worried it’s no longer supported.
