# Express Auth DB
## Usage
```js
const express = require('express');
const cookieParser = require('cookie-parser');
const crypto = require('crypto');
const {
setup,
authenticate,
login,
logout,
checkAuthenticated,
checkNotAuthenticated
} = require('express-auth-db');
// models
const Auth = require('./models/auth');
const User = require('./models/user');
const app = express();
const PORT = process.env.PORT || 3000;
setup({
cookieName: 'key',
authUserIdField: 'userId',
createAuth: (userId, key) => Auth.create({ userId, key, })
checkAuth: (key) => {
return Auth.findOne({
key,
expiresAt: {
$gt: Date.now()
}
}, {
userId: 1
});
},
deleteAuth: (key) => Auth.deleteOne({ key }),
getUser: (id) => User.findById(id),
setCookie: (res, key) => {
res.cookie('key', key, {
expires: new Date(Date.now() + 3155695200000) // 100 years
});
},
randomKey: () => {
return new Promise((resolve, reject) => {
crypto.randomBytes(64, (e, buf) => {
if (e) return reject(e);
resolve(buf.toString('hex'));
}
}));
},
redirectAuthenticated: '/profile',
redirectUnauthenticated: '/login',
});
app.use(cookieParser());
app.use(authenticate);
app.post('/login', checkNotAuthenticated, async (req, res) => {
const user = await User.findOne({ username: req.body.username });
if (user && user.checkPassword(req.body.password)) {
await login(user._id, res);
res.send('ok');
} else {
res.send('error');
}
});
app.post('/logout', checkAuthenticated, (req, res) => {
await logout(req, res);
res.redirect('/');
});
app.get('/check', (req, res) => {
if (req.isAuthenticated) {
res.send(':)');
} else {
res.send(':(');
}
});
app.get('/profile', checkAuthenticated, (req, res) => {
res.send(`name: ${req.user.name}`);
});
app.listen(PORT, () => {
console.log(`Server is running at https://localhost:${PORT}`);
});
```
