keq-exception v2.1.0

keq-exception

The keq-exception module is a package that can be used to throw and catch exceptions in keq-request.

Usage

import { request } from 'keq'
import { throwException, catchException, RequestException } from 'keq-exception'


request
  .use(catchException(err => {
    if (err instanceof RequestException) {
      context.redirect('/login')
    }

    context.redirect('/login')
    throw err
  }))
  .use(throwException({
    // there is the default options
    // wether or not to redirect to throw request exception
    condition: () => ctx => ctx.response && ctx.response.status >= 400,
    // the status code of request exception
    statusCode: ctx => ctx.response.status,
    // the message of request exception
    message: ctx => ctx.response.text(),
  }))

The order of keq middleware is important(like an onion).
