koa-basic-auth

Blanket basic auth middleware for koa

koa-basic-auth

Add simple "blanket" basic auth with username / password. If you require anything more specific just use the basic-auth module.

$ npm install koa-basic-auth

Password protect downstream middleware:

var auth = require('koa-basic-auth');
var koa = require('koa');
var app = koa();
 
// custom 401 handling 
 
app.use(function *(next){
  try {
    yield next;
  } catch (err) {
    if (401 == err.status) {
      this.status = 401;
      this.set('WWW-Authenticate', 'Basic');
      this.body = 'cant haz that';
    } else {
      throw err;
    }
  }
});
 
// require auth 
 
app.use(auth({ name: 'tj', pass: 'tobi' }));
 
// secret response 
 
app.use(function *(){
  this.body = 'secret';
});
 
app.listen(3000);
console.log('listening on port 3000');

Example request:

$ curl -H "Authorization: basic dGo6dG9iaQ==" http://localhost:3000/ -i
HTTP/1.1 200 OK

Using the mount middleware you may specify auth for a given prefix:

var mount = require('koa-mount');
var auth = require('koa-basic-auth');
 
app.use(mount('/admin', auth({ name: 'tobi', pass: 'ferret' })));
