custom http code

Currently koa seems to only handle standard code.

When i use a code like 420 with ctx.throw('custom message', 420) , koa replace it by a 500. When i use …

const err = new Error('custom message');
err.status = 420;
err.expose = true;
throw err;

… koa throw the error invalid status code: 420

I need to use custom code. Is there a way to add custom code to koa ?

so good answer is

let statuses = require('koa/node_modules/statuses')
statuses['700'] = 'custom status';
ctx.throw(700);

Would be usefull to give access to statuses in app

Look at the tests here: https://github.com/koajs/koa/blob/master/test/response/status.js

statuses['700'] = 'custom status';
