Description: Authentication library for Vue.js

# @simbachain/vue-authenticate

Fork of [vue-authenticate](https://github.com/dgrubelic/vue-authenticate) adding support for refresh tokens and PKCE auth code flow.

**vue-authenticate** is easily configurable solution for [Vue.js](https://vuejs.org/) that provides local login/registration as well as Social login using Github, Facebook, Google and other OAuth providers.



The best part about this library is that it is not strictly coupled to one request handling library like [vue-axios](https://github.com/imcvampire/vue-axios). You will be able to use it with different libraries. 

For now it is tested to work with  [vue-resource](https://github.com/pagekit/vue-resource) and [axios](https://github.com/mzabriskie/axios) (using [vue-axios](https://github.com/imcvampire/vue-axios) wrapper).

**WARNING:** From version 1.3.0 default request library is `axios` using `vue-axios` wrapper plugin.

This library was inspired by well known authentication library for Angular called [Satellizer](https://github.com/sahat/satellizer) developed by [Sahat Yalkabov](http://sahatyalkabov.com). They share almost identical configuration and API so you can easily switch from Angular to Vue.js project.

## Installation
```bash
npm install vue-authenticate
```

## Usage
```javascript
import Vue from 'vue'
import VueAxios from 'vue-axios'
import VueAuthenticate from 'vue-authenticate'
import axios from 'axios';

Vue.use(VueAxios, axios)
Vue.use(VueAuthenticate, {
  baseUrl: 'http://localhost:3000', // Your API domain
  
  providers: {
    github: {
      clientId: '',
      redirectUri: 'http://localhost:8080/auth/callback' // Your client app URL
    }
  }
})
```

### Email & password login and registration
```javascript
new Vue({
  methods: {
    login: function () {
      this.$auth.login({ email, password }).then(function () {
        // Execute application logic after successful login
      })
    },

    register: function () {
      this.$auth.register({ name, email, password }).then(function () {
        // Execute application logic after successful registration
      })
    }
  }
})
```

```html
<button @click="login()">Login</button>
<button @click="register()">Register</button>
```

### Social account authentication

```javascript
new Vue({
  methods: {
    authenticate: function (provider) {
      this.$auth.authenticate(provider).then(function () {
        // Execute application logic after successful social authentication
      })
    }
  }
})
```

```html
<button @click="authenticate('github')">auth Github</button>
<button @click="authenticate('facebook')">auth Facebook</button>
<button @click="authenticate('google')">auth Google</button>
<button @click="authenticate('twitter')">auth Twitter</button>
```

### Vuex authentication

#### Import and initialize all required libraries

```javascript
// ES6 example
import Vue from 'vue'
import Vuex from 'vuex'
import VueAxios from 'vue-axios'
import { VueAuthenticate } from 'vue-authenticate'
import axios from 'axios';

Vue.use(Vuex)
Vue.use(VueAxios, axios)

const vueAuth = new VueAuthenticate(Vue.prototype.$http, {
  baseUrl: 'http://localhost:4000'
})
```

```javascript
// CommonJS example
var Vue = require('vue')
var Vuex = require('vuex')
var VueAxios = require('vue-axios')
var VueAuthenticate = require('vue-authenticate')
var axios = require('axios');

Vue.use(Vuex)
Vue.use(VueAxios, axios)

// ES5, CommonJS example
var vueAuth = VueAuthenticate.factory(Vue.prototype.$http, {
  baseUrl: 'http://localhost:4000'
})
```

Once you have created VueAuthenticate instance, you can use it in Vuex store like this:

```javascript
export default new Vuex.Store({
  
  // You can use it as state property
  state: {
    isAuthenticated: false
  },

  // You can use it as a state getter function (probably the best solution)
  getters: {
    isAuthenticated () {
      return vueAuth.isAuthenticated()
    }
  },

  // Mutation for when you use it as state property
  mutations: {
    isAuthenticated (state, payload) {
      state.isAuthenticated = payload.isAuthenticated
    }
  },

  actions: {

    // Perform VueAuthenticate login using Vuex actions
    login (context, payload) {

      vueAuth.login(payload.user, payload.requestOptions).then((response) => {
        context.commit('isAuthenticated', {
          isAuthenticated: vueAuth.isAuthenticated()
        })
      })

    }
  }
})
```

Later in Vue component, you can dispatch Vuex state action like this

```javascript
// You define your store logic here
import store from './store.js'

new Vue({
  store,

  computed: {
    isAuthenticated: function () {
      return this.$store.getters.isAuthenticated()
    }
  },

  methods: {
    login () {
      this.$store.dispatch('login', { user, requestOptions })
    }
  }
})
```

### Custom request and response interceptors

You can easily setup custom request and response interceptors if you use different request handling library.

**Important**: You must set both `request` and `response` interceptors at all times.

```javascript

/**
* This is example for request and response interceptors for axios library
*/

Vue.use(VueAuthenticate, {
  bindRequestInterceptor: function () {
    this.$http.interceptors.request.use((config) => {
      if (this.isAuthenticated()) {
        config.headers['Authorization'] = [
          this.options.tokenType, this.getToken()
        ].join(' ')
      } else {
        delete config.headers['Authorization']
      }
      return config
    })
  },

  bindResponseInterceptor: function () {
    this.$http.interceptors.response.use((response) => {
      this.setToken(response)
      return response
    })
  }
})

```

### SSR Support

You can use this library on the server side without problems by following the steps below.

1. You must configure the storage as 'cookieStorage', adding to your VueAuthenticate configuration `storageType:' cookieStorage'`.
2. You have to stop using Vue.use(VueAuthenticate) globally, instead, you have to use `VueAuthenticate.factory()`
3. On the server you have to build your own storage (cookie storage will not work) or use the StorageMemory.
4. You have to consider having an instance of axios for each of the requests.

Here an example with plugins of [!UVue](https://github.com/universal-vue/uvue)

Axios Plugin:

```javascript
import axios from 'axios';

import cookies from 'js-cookie'; // only browser

/**
 * This plugin create an axios HTTP client to do request.
 */

export default {
  async beforeCreate(context, inject) {
    // Create axios client
    const httpClient = axios.create({ 
      // Change API url: depends on server side or client side
      baseURL: '/api/v1',
    });

    // Inject httpClient eveywhere
    inject('http', httpClient);
    inject('axios', httpClient);

    // You can use it everywhere in your app:
    // - In UVue context: `context.$http.get(...)`
    // - In your components: `this.$http.get(...)`
    // - In your store actions: `this.$http.get(...)`
  },
};

```

VueAuthenticate Plugin

```javascript
import VueAuthenticate from 'vue-authenticate/dist/vue-authenticate';

const vueAuthenticateConfig = {
  // ... 
  tokenPrefix: undefined,
  tokenName: 'token',
  storageType: 'cookieStorage', // Important.
  // ...
};

export default {
  async beforeCreate(context, inject) {
    let vueAuthInstance;
    if (process.client) { // browser
      vueAuthInstance = VueAuthenticate.factory(context.$http, vueAuthenticateConfig);
    } else { // server
      const vueConfig = { ...vueAuthenticateConfig, storageType: 'memoryStorage' }; // Override with memory storage
      const { tokenName } = vueConfig; // get the token name
      const accessToken = context.req.cookies[tokenName]; // Get the access token from request

      vueAuthInstance = VueAuthenticate.factory(context.$http, vueConfig);
      vueAuthInstance.storage.setItem(tokenName, accessToken); // set the current access token 
    }

    inject('auth', vueAuthInstance); // Inject auth eveywhere

    // You can use it everywhere in your app:
    // - In UVue context: `context.$auth.isAuthenticated(...)`
    // - In your components: `this.$auth.isAuthenticated(...)`
    // - In your store actions: `this.$auth.isAuthenticated(...)`
  },
};
```
