Just-auth NPM | npm.io

just-auth

Simple SPA focused token based authentication for Express.js This library follows convention over configuration, but configuration is available :wink:.

Installation

Download node at nodejs.org and install it, if you haven't already.

npm install just-auth --save

Usage

const express = require('express');
const justAuth = require('just-auth');
const app = express();
const auth = justAuth({
  secret: 'c47sRfunny101',

  getUser(email, callback) {
    // if error: callback({ myerror: 'failure' });
    // if success: callback(undefined, { email: 'my@email', passwordHash: '%asdaq42ad..' });
  },

  // Default behavior (don't specify if this suites you)
  configureToken(user) {
    // user without passwordHash
    return user;
  }
});

app.use('/auth', auth.router);

// Can also use `succeeded()` and `failed()` for redirects, etc.
// See https://www.npmjs.com/package/express-authentication
app.use('/api/admin', auth.middleware.required());

app.listen(80);

POST to /auth/login with { email: 'my@email', password: 'bacon' }. Result will be JSON, e.g. { token: '2mkql3...' }.

Note: To use the built in password utilities, you can use the following:

const passUtils = require('just-auth/lib/password');

const isValid = passUtils.validate(pass, hash);

passUtils.hash(pass, function (err, hash) {
  // error or hash
});
