koa-field-checker

Middleware to check a request body for specific fields and generate nicely formatted errors if any are missing. If a field is missing from the input list, a 401 Bad Request will be generated, otherwise the middleware will simply pass through.

Installation

yarn add koa-field-checker

Example

import Koa from 'koa'
import Router from 'koa-router'
import fields from 'koa-field-checker'

const app = new Koa()
const router = new Router()

app
  .use(router.routes())
  .use(router.allowedMethods())

router.get('/:id', fields(["username", "password"]), function async (ctx, next) {
  ...
})
