accountdown-basic

username/password authentication for accountdown using salted hashes

example

create an account

var accountdown = require('accountdown');
var level = require('level');
var db = level('/tmp/users.db');

var users = accountdown(db, {
    login: { basic: require('accountdown-basic') }
});

var user = process.argv[2];
var pass = process.argv[3];
var bio = process.argv[4];

var opts = {
    login: { basic: { username: user, password: pass } },
    value: { bio: bio }
};
users.create(user, opts, function (err) {
    if (err) console.error(err);
});

verify credentials

var accountdown = require('accountdown');
var level = require('level');
var db = level('/tmp/users.db');

var users = accountdown(db, {
    login: { basic: require('accountdown-basic') }
});

var creds = {
    username: process.argv[2],
    password: process.argv[3]
};
users.verify('basic', creds, function (err, ok) {
    if (err) console.error(err)
    else console.log('verified:', ok)
});

With these two programs, we can create an account and then verify the user/pass:

$ node example/create.js substack beepboop 'oh hello'
$ node example/verify.js substack beepboop
verified: true
$ node example/verify.js substack bleep
verified: false

without accountdown

Modules should be written to be useful on their own where possible. You can use this module without accountdown too:

var level = require('level');
var db = level('/tmp/users.db', {
    keyEncoding: require('bytewise'),
    valueEncoding: 'json'
});
var basic = require('../');
var batch = require('level-create-batch');

var b = basic(opts, [ 'login', 'basic' ]);

var user = process.argv[2];
var pass = process.argv[3];

var creds = { username: user, password: pass };
batch(db, b.create(user, creds));

methods

var basic = require('accountdown-basic')

var b = basic(db, prefix, opts)

Return a basic auth instance b given a database handle db and an array prefix prefix.

Optionally set an opts.key to use a different key as the identity than username.

b.create(id, creds)

Create a new login for the account identified by id with creds, an object with username and password properties.

Return an array of rows that can be fed into level-create-batch.

b.verify(creds, cb)

Verify creds, a username with username and password properties.

cb(err, success, id) fires with any errors or a boolean success and the account identifier id.

install

With npm do:

npm install accountdown-basic
