1. Create new Express app.
`express`
2. Install Lockit and sessions via npm.
`npm install && npm install lockit cookie-session --save`
3. Use `lockit` and `cookie-session` in your Express `app.js`.
```js
var cookieSession = require('cookie-session');
var Lockit = require('lockit');
var lockit = new Lockit();...
app.use(cookieSession({
secret: 'my super secret String'
}));
app.use(lockit.router);
```4. Go to [localhost:3000/signup](http://localhost:3000/signup)
By default Lockit uses an in-memory SQLite database.
So you don't have to set up any db. Lockit will just work.
Check out the [default example](https://github.com/zemirco/lockit/tree/master/examples/default).For production use a persistent data store!
## Full installation
1. Install and require
`npm install lockit --save`
```js
var config = require('./config.js');
var Lockit = require('lockit');var app = express();
// express middleware
// ...
// sessions are required
app.use(cookieParser());
app.use(cookieSession({
secret: 'your secret here'
}));var lockit = new Lockit(config);
app.use(lockit.router);
// you now have all the routes like /login, /signup, etc.
// and you can listen on events. For example 'signup'
lockit.on('signup', function(user, res) {
console.log('a new user signed up');
res.send('Welcome!'); // set signup.handleResponse to 'false' for this to work
});
```2. Add styles
Views are built with [bootstrap](http://getbootstrap.com/).
You can use [your own ones](#custom-views) though!
Use Bootstrap CDN and add the following line to your `layout.jade````jade
link(rel='stylesheet', href='//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css')
```3. Install database adapter
`npm install lockit-[DB]-adapter` where `[DB]` can be
| Database | Command |
| --- | --- |
| [CouchDB](https://github.com/zemirco/lockit-couchdb-adapter) | `npm install lockit-couchdb-adapter` |
| [MongoDB](https://github.com/zemirco/lockit-mongodb-adapter) | `npm install lockit-mongodb-adapter` |
| [SQL (PostgreSQL, MySQL, MariaDB or SQLite)](https://github.com/zemirco/lockit-sql-adapter) | `npm install lockit-sql-adapter` |If you use a SQL database you also have to install the connector.
```
npm install pg # for postgres
npm install mysql # for mysql
npm install sqlite3 # for sqlite
npm install mariasql # for mariasql
```## Configuration
You need a `config.js` somewhere in your app.
### Database connection
Add the database connection string to your `config.js`.
```js
// database settings for CouchDB
exports.db = 'http://127.0.0.1:5984/'; // connection string for database// or if you want to use MongoDB
// exports.db = {
// url: 'mongodb://127.0.0.1/',
// name: 'test',
// collection: 'users' // collection name for MongoDB
// };// PostgreSQL
// exports.db = {
// url: 'postgres://127.0.0.1:5432/',
// name: 'users',
// collection: 'my_user_table' // table name for SQL databases
// };// MySQL
// exports.db = {
// url: 'mysql://127.0.0.1:3306/',
// name: 'users',
// collection: 'my_user_table'
// };// SQLite
// exports.db = {
// url: 'sqlite://',
// name: ':memory:',
// collection: 'my_user_table'
// };
```### Sending emails
By default the email service is stubbed and no emails are sent.
That means that you won't receive any signup and password reset tokens.
You have to look them up in your database and call the routes manually (e.g. `/signup/:token`).
To send emails you need an email server and you have to change the settings in your `config.js`:- `emailType` - usually `nodemailer-smtp-transport`
- `emailSettings` - see [nodemailer](https://github.com/andris9/Nodemailer) for more informationWith [mailgun](http://www.mailgun.com/pricing) you can send up to 10,000 emails per month for free.
```js
exports.emailType = 'nodemailer-smtp-transport';
exports.emailSettings = {
service: 'Mailgun',
auth: {
user: '[email protected]',
pass: 'secret-password'
}
};
```### Custom views
Lockit comes with built-in views which are based on Bootstrap.
If you want to use your own custom views you can. It is dead simple.Put them into your `views` folder, for example `views/lockit/myLogin.jade`.
Then edit your `config.js` and set the path to your custom view.```js
exports.login = {
route: '/login',
logoutRoute: '/logout',
views: {
login: 'lockit/myLogin.jade',
loggedOut: 'lockit/myLogoutSuccess.jade'
}
};
```The only thing you have to keep in mind is the structure. The `login.views.login` view, for example,
needs a form element with two input fields. The `method` has to be `POST` and `action` should point
to your `login.route`. The input fields have to have the names `login` and `password`. If something
went wrong during the login process you'll get an `error` variable that you can use in your template.Here is a minimalistic example for an alternative `myLogin.jade`.
```jade
extend /layoutblock content
h1 Login
form(action="/login", method="POST")
div
label(for="login") Email or Username
input(type="text", id="login", name="login", placeholder="Your email or username")
div
label(for="password") Password
input(type="password", id="password", name="password", placeholder="Your password")
if error
p #{error}
input(type="submit", value="Login")
```For more information about each view see the `views` folder inside the different repositories.
Make sure your view extends `/layout` which is different to your normal views. They extend `layout`
without the slash. This is required to find the view.## Events
Lockit emits the most important events for user authentication. Those are
- `signup`
- `login`
- `logout`
- `delete`You can use these events to intercept requests and implement some custom logic,
like getting the gravatar before sending a response to the client.##### `signup`
A new user signed up. The callback function has two arguments.
- `user` is an object and contains information about the new user, like `user.name` or `user.email`.
- `res` is the standard Express.js `res` object with methods like `res.render` and `res.send`.
If you've set `signup.handleResponse` to `false` Lockit will not handle the response for you.
You therefore have to send the response back to the client manually or otherwise it will wait forever.```js
lockit.on('signup', function(user, res) {
// ...
});
```##### `login`
A user logged in. Callback function this time has three arguments.
- `user` is again the JSON object containing info about that particular user.
- `res` is the normal Express.js response object with all properties and methods.
- `target` is the redirect target route after a successful login, i.e. `/settings````js
lockit.on('login', function(user, res, target) {
// ...
});
```##### `forgot::sent`
A user forgot the password and an email has been sent.
Callback function has two arguments.- `user` is again the JSON object containing info about that particular user.
- `res` is the normal Express.js response object with all properties and methods.```js
lockit.on('forgot::sent', function(user, res) {
// ...
});
```##### `forgot::success`
User has created a new password. Callback function has two arguments.
- `user` is again the JSON object containing info about that particular user.
- `res` is the normal Express.js response object with all properties and methods.```js
lockit.on('forgot::success', function(user, res) {
// ...
});
```##### `logout`
A user logged out. Same as above without the `target` string.
```js
lockit.on('logout', function(user, res) {
// ...
});
```##### `delete`
A user deleted an account. Same callback as above.
```js
lockit.on('delete', function(user, res) {
// ...
});
```## REST API
In a single page application (SPA) all routing and template rendering is done on the client.
Before version 0.5.0 Lockit caught relevant routes, like `/login` or `/signup`,
and did the entire rendering on the server.Starting with version 0.5.0 you're able to use Lockit as a REST API and communicate via JSON.
All you have to do is set `exports.rest` in your `config.js`.```js
exports.rest = {
// set starting page for single page app
index: 'public/index.html',// use view engine (render()) or send static file (sendfile())
useViewEngine: false
}
```With REST enabled all default routes get a `/rest` prefix so you can catch `/login`
on the client. To allow for true page refreshes (i.e. user is at `/login` and refreshes the page)
all routes on the server, like `/login` and `/signup`, send the `rest.index` view
to the client. From there your SPA has to take over.Here is a short example how the process works.
1. User sends GET request for `/login`
2. Server has a route handler for this request and sends `index.html` back
3. Client router takes over and renders `/login` page
4. User enters credentials and submits the form
5. Client controller catches submit and sends POST via AJAX request to `/rest/login`
6. Server handles POST request and validates user credentials
7. Server sends status code `200` or some JSON with error message
8. Client reacts to JSON from server and redirects on success or shows errorI've built a [simple example](https://github.com/zemirco/lockit/tree/master/examples/angular)
using AngularJS on the client side.## Sample config
If you want to go crazy and customize all the things you can:
```js
// name for subject and email content
exports.appname = 'lockit - Test App';// url for proper link generation
exports.url = 'http://localhost:3000';// email settings (same as nodemailer)
exports.emailType = 'nodemailer-stub-transport';
exports.emailSettings = {
service: 'none',
auth: {
user: 'none',
pass: 'none'
}
};// whenever a library uses request under the hood (like nano in lockit-couchdb-adapter)
// the following values will be used
exports.request_defaults = {
// proxy: 'http://someproxy'
};// email template from npm
exports.emailTemplate = 'lockit-template-blank';// render views or json for single page apps
exports.rest = false;// or if you want to use rest
// exports.rest = {
//
// // set starting page for single page app
// index: 'public/index.html',
//
// // use view engine (render()) or send static file (sendfile())
// useViewEngine: false
//
// }// signup settings
exports.signup = {

signedUp: '', // message email has been sent => check your inbox
resend: '' // input field 'email' | local variable 'error' | POST /'signup.route'/resend-verification
},
handleResponse: true // let lockit handle the response after signup success
