This module use Nuxt auth module https://auth.nuxtjs.org for bearer authentication.
$auth is automatically injected by this module, and it'll be used for handling user authentication.
It must be installed and setup before using it.

yarn add @nuxtjs/axios

// nuxt.config.js
{
    modules: [
        '@nuxtjs/axios',
        '@nuxtjs/auth-next'
    ], 
    auth: {
        strategies: {
            roadiz: {
                provider: require.resolve('./node_modules/@roadiz/nuxt-realm/dist/auth-provider.js'), 
                baseURL: 'https://api.example.com' // optional
            }
        },
        // i18n (optional)
        plugins: [require.resolve('./node_modules/@roadiz/nuxt-realm/dist/auth-i18n.js')]
    }
}

The RoadizRealm component

The module comes with a built-in component <RoadizRealm> for display a Roadiz realm.
It's a renderless component, it can wrap only one root component.

<template>
    <roadiz-realm :response="myRoadizWebResponse">
      <div> // or any other tag / component
        // ... 
      </div>
    </roadiz-realm>
</template>

This component provides methods and properties for handling realm state.

export interface RoadizRealmProvide {
    realm?: RoadizSecureRealm // active realm
    realmAuthWithPassword(password: string): Promise<void> // authenticate with password
    realmHasPassword(): boolean // is there already a filled password for this realm
    realmIsBearerScheme: boolean // bearer authentication scheme 
    realmIsPasswordScheme: boolean // plain password authentication scheme 
    realmIsAuthenticated(): boolean // is the current realm already authenticated (with user for bearer scheme or password for password scheme) 
}

These methods and properties can be injected into any child component.

Active realm

export default Vue.extend({
    inject: ['realm'],
})

Testing authentication scheme

<template>
    <login-form v-if="realmIsBearerScheme && !$auth.loggedIn" />
</template>

export default Vue.extend({
    inject: ['realmIsBearerScheme'],
})

Authenticate with plain password (password scheme)

<template>
    <form @submit="submit">
      <input type="password" v-model="password" />
      // ...
    </form>
</template>

export default Vue.extend({
    inject: ['realmAuthWithPassword'],
    data() {
        return {
            password: ''
        }
    },
    methods: {
        submit(event: Event) {
            event.preventDefault()
            
            this.realmAuthWithPassword(this.password)
        }
    }
})

Testing if active realm has a stored password

<template>
    <password-form v-if="!hasPassword" />
</template>

export default Vue.extend({
    inject: ['realmHasPassword'],

    computed: {
        hasPassword(): boolean {
            return this.realmHasPassword() // use a computed prop with a getter for using data reactivity
        }
    }
})

Authenticate with user (bearer scheme)

<template>
    <form @submit="submit">
      <input type="username" v-model="login.username" />
      <input type="password" v-model="login.password" />
      // ...
    </form>
</template>

export default Vue.extend({
    data() {
        return {
            login: {
                username: '',
                password: ''
            }
        }
    },
    methods: {
        submit(event: Event) {
            event.preventDefault()

            this.$auth.loginWith('roadiz', { data: this.login })
        }
    }
})
