Getting Started: index.js

const bodyparser = require('koa-body') // middleware

entix.use(bodyparser())
// load more global middleware here ...

Adding ErrorHandlers: index.js

const { ValidationError } = require('entixio').joi
const { UniqueViolationError } = require('entixio').objection
const { JsonWebTokenError } = require('jsonwebtoken')

const validationErrorHandler = async ({ctx, error}) => {
    if(error instanceof ValidationError){

        ctx.status = 422
        const { details, _original } = error
        error = { original: _original, details: {}}
        details.map(d => error.details[d.context.key] = d.message)
        return error

const databaseErrorHandler = async ({ctx, error}) => {

        const key = error.columns.pop()
        error = { original: ctx.request.body, details: {}}
        error.details[key] = `this ${key} is already taken`
        return error

}

const jwtErrorHandler = async ({ctx, error}) => {
