Music Generator

Introduction

The Music Generator is a tool that leverages Replicate's API to generate music based on the user prompt. Users can specify the genre, mood, and duration of the music to be generated.

Quickstart Guide

Installation

Clone the repository:
terminal
```
git clone https://github.com/1811-Labs-LLC/BuilderKit-Pro.git [YOUR_APP_NAME]
 
cd [YOUR_APP_NAME]
 
git checkout music-generator
```
Remove the origin remote to ensure that you can work locally without pushing the changes back to the original repository.
terminal
```
git remote remove origin
```
However, note that after removing the remote, you won't be able to switch between the branches, so you'll need to clone the repository again if you want to work on another branch.
Install dependencies:
terminal
```
npm install
```

Environment Variables:

Copy the required variables from .env.example to .env.local as mentioned and update the values.

terminal

cp .env.example .env.local

Or, manually create a .env.local file in the root directory with the following env variables (make sure to update the values with your actual keys):

.env.local

# Host
NEXT_PUBLIC_APP_URL=<your-app-url>
 
# Supabase
NEXT_PUBLIC_SUPABASE_URL=<your-supabase-url>
NEXT_PUBLIC_SUPABASE_ANON_KEY=<your-supabase-anon-key>
SUPABASE_SERVICE_ROLE_KEY=<your-supabase-service-role-key>
SUPABASE_STORAGE_BUCKET_NAME=<your-supabase-storage-bucket-name>
 
# Replicate
REPLICATE_API_TOKEN=<your-replicate-api-key>
 
# Replicate model to be used for music generation
# Available options: 'meta' | 'riffusion'
MODEL_IN_USE=<model-to-be-used-for-music-generation>
 
# Lemon Squeezy
LEMON_SQUEZY_BASE_URL=<your-lemonsqueezy-base-url>
LEMON_SQUEEZY_API_KEY=<your-lemonsqueezy-api-key>
LEMON_SQUEEZY_WEBHOOK_SECRET=<your-lemonsqueezy-webhook-scret>
 
# Stripe
STRIPE_SECRET_KEY=<your-stripe-secret-key>
STRIPE_WEBHOOK_SECRET=<your-stripe-webhook-secret>

NEXT_PUBLIC_GOOGLE_ANALYTICS_KEY=<your-google-analytics-key>

💡

Note: To switch beteen availables music generation models set the respective value for MODEL_IN_USE in env. Available options: meta | riffusion. If it is not set, by default "meta" will be used.

Setup Supabase

If you have not setup the supabase yet, go through the detailed documentation to set up the supabase for BuilderKit.ai. Make sure that you are creating the user table as mentioned in the supabase setup doc as it is required for the tool.

Create Music Generator Table in Supabase:

sql

-- Create a table for Music Generator
create table
music_generations (
   id uuid not null default uuid_generate_v4 (),
   created_at timestamp with time zone not null default now(),
   user_id uuid not null,
   prompt text not null,
   genre text not null,
   mood text not null,
   duration int not null,
   prediction_id text not null,
   music_url text null,
   error text null,
   constraint music_generations_pkey primary key (id),
   constraint music_generations_user_id_fkey foreign key (user_id) references users (id)
);
 
-- Set up Row Level Security (RLS)
alter table music_generations enable row level security;
 
create policy "Users can insert their own row." on music_generations for insert
with
check (auth.uid () = user_id);
 
create policy "Users can update own row" on music_generations
for update
using (auth.uid () = user_id);
 
create policy "Users can read own row" on music_generations for
select
using (auth.uid () = user_id);
 
-- Enable Realtime
alter publication supabase_realtime add table music_generations;

For Music Generator tool, we are enabling Supabase Realtime (last line of the script)

For all the tables, we enable the RLS policy by default with necessary permissions as mentioned in the script.

⚠️

Sync Supabase Types: It is mandatory to sync your updated supabase table with your application, otherwise you will get typescript error while deploying the application. To sync the supabase table schema with your project follow the steps here (opens in a new tab).

Configure Payments & Webhook

BuilderKit supports both Lemon Squeezy & Stripe as the payment method. You can either use both (current state) or use any specific payment method as per your requirements.

Set the required environment variables in your .env file:

Replace the placeholder values with your actual Lemon Squeezy credentials:

.env

LEMON_SQUEZY_BASE_URL=your_lemon_squeezy_base_url
LEMON_SQUEEZY_API_KEY=your_lemon_squeezy_api_key
LEMON_SQUEEZY_WEBHOOK_SECRET=your_lemon_squeezy_webhook_secret

Update the src/config.ts file with your Lemon Squeezy configuration details:

src/config.ts

const config = {
  // ...
  lemonSqueezy: {
    baseUrl: "https://builderkit.lemonsqueezy.com/buy",
    emailParam: "checkout[email]",
    discountParam: "checkout[discount_code]",
    variant: {
      standard: {
        monthly: "81395ea4-4049-49a7-a11e-3ccdf620ce7e",
        annually: "feb7cf4b-d0e0-4f04-a4e9-55d4415824ff",
      },
      premium: {
        monthly: "eb0503cb-a58a-4a30-8fdf-86fa977bd3cb",
        annually: "cde373b7-1619-4788-9e6b-664ba048f693",
      },
    },
    plan: {
      245697: "standard",
      245701: "premium",
    },
  },
  // ...
};

baseUrl: The base URL for Lemon Squeezy checkout sessions.
emailParam: The parameter used to prefill the email input in the checkout form.
discountParam: The parameter used to prefill a discount code in the checkout form (optional).
variant: Mapping of product tiers and frequencies to Lemon Squeezy variant IDs.
plan: Mapping of Lemon Squeezy product IDs to subscription types.

Adjust the variant and plan mappings based on your Lemon Squeezy product setup.

BuilderKit includes a webhook handler for processing Lemon Squeezy subscription events. The webhook route is defined in src/app/api/webhooks/lemon-squeezy/route.ts.

⚠️

Make sure to configure the webhook endpoint in your Lemon Squeezy dashboard to point to the appropriate URL - https://your-domain.com/api/webhooks/lemon-squeezy (opens in a new tab). Replace your-domain with your project's domain.

Running the Application

Run the development server:
terminal
```
npm run dev
```
This will start the development server on http://localhost:3000 (opens in a new tab).
Build for production:
terminal
```
npm run build
```
This command compiles the application for production usage.
Start the production server:
terminal
```
npm start
```
This will start the application in production mode.

Additional Scripts

Prepare Husky for Git hooks:

This script sets up Husky, which enables Git hooks in the project. Git hooks allow you to run scripts automatically before certain Git events (like committing code), which helps maintain code quality by enforcing checks before code is committed.
terminal
```
npm run prepare
```
Validate the code with Linting, Formatting & Typecheck:

This script runs linting, formatting checks, and type checking in a single command. It's a convenient way to ensure your code meets the project's quality standards before pushing changes or deploying.
terminal
```
npm run validate
```

Creating a Public URL for Local Webhook Testing

This app uses a webhook to handle responses from the AI server. Since the server cannot recognize a localhost URL (http://localhost:3000 (opens in a new tab)), we need to set up a tunnel to create a public URL that can accept webhook requests from the server and redirect them to your localhost URL for testing purposes.

We will use ngrok (opens in a new tab) to create this tunnel. The public URL generated by ngrok will redirect all external requests to your configured localhost URL. Follow the steps to set up ngrok and create the public URL here: https://ngrok.com/docs/getting-started (opens in a new tab).

Once ngrok is set up, test your project using the ngrok public URL instead of http://localhost:3000 (opens in a new tab).

Deployment

To deploy the application to a live environment, follow this comprehensive deployment guide.
