Installation

Instructions for installing Fireactjs SaaS packages and creating your Reactjs SaaS application with the Fireactjs packages.

Create Reactjs App with Fireactjs Core

Before installing the Fireactjs SaaS packages, you must set up your Reactjs application with the Fireactjs Core package for user authentication. Read Fireactjs Installation Guide.

Install from NPM

The Fireactjs SaaS project comes with two packages: @fireacjts/saas for the Reactjs front-end and @fireactjs/saas-cloud-functions for the server-side Firebase Cloud Functions.

In your Reactjs app root folder, use the following command to install the @fireactjs/saas package:

npm i @fireactjs/saas

In your /functions folder where your Firebase Cloud Functions are located, use the following command to install the @fireactjs/saas-cloud-functions package:

npm i @fireactjs/saas-cloud-functions

Setup Payment Plans

Fireactjs SaaS integrates with Stripe to handle subscription payments. You must have a Stripe account to enable the integration.

In Stripe, create a product for your SaaS. You can have multiple subscription plans, including both free and paid plans. Create a price plan under your subscription product for each plan. Stripe will create a price_id for each price plan.

Create a JSON file called plans.json in the /src folder and the /functions folder to describe the subscription plans of your SaaS product as the example shows below. The plans will be shown in the pricing table as the property values in the Reactjs application and will be used for the subscription process in the cloud functions. It’s important that the priceId property value of each plan matches the plan’s price_id in Stripe.

[
    {
        "title": "Free",
        "popular": false,
        "priceId": "price_1...",
        "currency": "$",
        "price": 0,
        "frequency": "week",
        "description": [
            "10 users included",
            "2 GB of storage",
            "Help center access",
            "Email support"
        ]
    },
    {
        "title": "Weekly",
        "popular": true,
        "priceId": "price_2...",
        "currency": "$",
        "price": 10,
        "frequency": "week",
        "description": [
            "20 users included",
            "10 GB of storage",
            "Help center access",
            "Priority email support"
        ]
    },
    {
        "title": "Daily",
        "popular": false,
        "priceId": "price_3...",
        "currency": "$",
        "price": 5,
        "frequency": "day",
        "description": [
            "50 users included",
            "30 GB of storage",
            "Help center access",
            "Phone & email support"
        ]
    }
]

Setup Stripe Integration

For the cloud functions to receive data from Stripe, you will need to create a webhook endpoint with the cloud function webhook URL https://firebse-location-project-id.cloudfunctions.net/fireactjsSaas-stripeWebHook. Please make sure you replace the domain with your actual Firebase project cloud function domain. Once the webhook is created, you will get an endpoint secret which is needed in the configuration file.

The following Stripe events need to be sent to the endpoint:

customer.subscription.updated
customer.subscription.trial_will_end
customer.subscription.pending_update_expired
customer.subscription.pending_update_applied
customer.subscription.deleted
customer.subscription.created
invoice.created
invoice.deleted
invoice.finalized
invoice.marked_uncollectible
invoice.paid
invoice.payment_action_required
invoice.payment_failed
invoice.payment_succeeded
invoice.sent
invoice.updated
invoice.voided

Create /src/config.json File

Create a file called config.json in the /src folder as the example shows below store the configuration settings.

To integrate with Stripe, the Stripe public API key is required for the stripe.pubblic_api_key property.

The Reactjs application needs the price_id from Stripe to integrate with the Stripe payment plans. The plans will be shown in the pricing table as the property values in the JSON plans. It’s important that the priceId property value of each plan matches the plan’s price_id in Stripe.

{
    "stripe": {
        "public_api_key": "pk_test_..."
    },
    "plans": [
        {
            "title": "Free",
            "popular": false,
            "priceId": "price_1...",
            "currency": "$",
            "price": 0,
            "frequency": "week",
            "description": [
                "10 users included",
                "2 GB of storage",
                "Help center access",
                "Email support"
            ]
        },
        {
            "title": "Weekly",
            "popular": true,
            "priceId": "price_2...",
            "currency": "$",
            "price": 10,
            "frequency": "week",
            "description": [
                "20 users included",
                "10 GB of storage",
                "Help center access",
                "Priority email support"
            ]
        },
        {
            "title": "Daily",
            "popular": false,
            "priceId": "price_3...",
            "currency": "$",
            "price": 5,
            "frequency": "day",
            "description": [
                "50 users included",
                "30 GB of storage",
                "Help center access",
                "Phone & email support"
            ]
        }
    ],
    "permissions": {
        "access": {
            "default": true,
            "admin": false
        },
        "admin": {
            "default": false,
            "admin": true
        }
    },
    "subscription": {
        "singular": "project",
        "plural": "projects"
    }
}

Create /functions/config.json File

In the /functions folder, create a config.json file as the example shows below.

You will need to put in the stripe secret API key and the endpoint secret in the configuration file to integrate the cloud functions with Stripe.

Plans are also needed for the cloud functions similar to the Reactjs application.

For sending new user invites, the mailgun JSON is needed. The details are covered in the next section.

{
    "brand": "My Brand",
    "site_name": "My SaaS App",
    "site_url": "https://app.mydomain.com",
    "sign_in_url": "https://app.mydomain.com/sign-in",
    "sign_up_url": "https://app.mydomain.com/sign-up",
    "stripe": {
        "secret_api_key": "sk_test_...",
        "end_point_secret": "whsec_..."
    },
    "plans": [
        {
            "title": "Free",
            "popular": false,
            "priceId": "price_1...",
            "currency": "$",
            "price": 0,
            "frequency": "week",
            "description": [
                "10 users included",
                "2 GB of storage",
                "Help center access",
                "Email support"
            ]
        },
        {
            "title": "Weekly",
            "popular": true,
            "priceId": "price_2...",
            "currency": "$",
            "price": 10,
            "frequency": "week",
            "description": [
                "20 users included",
                "10 GB of storage",
                "Help center access",
                "Priority email support"
            ]
        },
        {
            "title": "Daily",
            "popular": false,
            "priceId": "price_3...",
            "currency": "$",
            "price": 5,
            "frequency": "day",
            "description": [
                "50 users included",
                "30 GB of storage",
                "Help center access",
                "Phone & email support"
            ]
        }
    ],
    "permissions": {
        "access": {
            "default": true,
            "admin": false
        },
        "admin": {
            "default": false,
            "admin": true
        }
    },
    "mailgun": {
        "api_key": "...",
        "domain": "app.mydomain.com",
        "from": "No Reply <[e-mail]>",
        "templates":{
            "invite_email": "invite"
        }
    }
}

Setup Mailgun Integration (optional)

The framework integrates with Mailgun to send invite emails when users are invited to join subscription accounts. To setup the integration, retrieve the API key from Mailgun and create a file called mailgun.json under the src folder as the example below shows.

{
    "api_key": "...",
    "domain": "app.mydomain.com",
    "from": "No Reply <[e-mail]>",
    "templates":{
        "invite_email": "invite"
}

In Mailgun, you will need a template for the invite emails. Create a template called invite with the subject line below.

{{sender}} invited you to {{site_name}}

In the template body, use the following copy.

Hi {{name}},

You received this invite because {{sender}} invited you to join {{site_name}}. Please sign in ({{sign_in_url}}) to accept the invite.

If you don't have a user account yet, please sign up ({{sign_up_url}}) here.

Best regards,

The {{site_name}} team

The invite template supports the following variables:

• {{sender}} - the name of the person who sends the invite
• {{site_name}} - the name of your web application defined in the cloud function configurations
• {{name}} - the name of the new user who is invited by the sender
• {{sign_in_url}} - the URL to the sign-in page which is defined in the cloud function configurations
• {{sign_up_url}} - the URL to the sign-up page which is defined in the cloud function configurations

Note: The invite email is optional for the invite process. You can skip this step but the new users will need to be informed by other methods so that they know where to sign up and sign in to accept the invites.

Update Firestore Rules

The SaaS package uses Firestore database to store and manage the subscription data. To secure the data, the following Firestore rules need to be added to your Firestore database rules.

match /users/{userId}/paymentMethods/{paymentMethodId} {
    allow read, update, create, delete: if request.auth.uid == userId;
}
match /subscriptions/{subscriptionId} {
    allow read: if request.auth.uid != null && request.auth.uid in resource.data.permissions.access;
    allow update: if request.auth.uid != null && request.auth.uid in resource.data.permissions.admin && (!request.resource.data.diff(resource.data).affectedKeys()
        .hasAny(['currency', 'ownerId', 'paymentCycle', 'paymentMethod', 'plan', 'price', 'stripePriceId', 'stripeSubscriptionId', 'subscriptionCreated', 'subscriptionCurrentPeriodEnd', 'subscriptionCurrentPeriodStart', 'subscriptionEnded', 'subscriptionStatus']));
}
match /subscriptions/{subscriptionId}/invoices/{invoiceId} {
    allow read: if request.auth.uid != null && request.auth.uid in get(/databases/$(database)/documents/subscriptions/$(subscriptionId)).data.permissions.admin;
}
match /invites/{inviteId} {
    allow read, delete: if request.auth.uid != null && request.auth.token.email == resource.data.email;
}

Modify /src/App.js

Replace the code in your src/App.js with the code below.
