How to use Supabase in a monorepo?

 

Step 1: Setting Up a Monorepo Structure

 

To use Supabase in a monorepo, start by setting up a monorepo structure. A common tool for setting up monorepos is Nx or Lerna. Here is an example using Nx.

npx create-nx-workspace@latest supabase-monorepo

Follow the prompts to set up your workspace. Choose a package-based setup if prompted, so you can manage multiple projects more effectively.

 

Step 2: Adding a Supabase Project

 

Once your monorepo is ready, you can add a Supabase project. First, sign up and log in to Supabase and create a new project. Note your project's URL and API key as you'll need these to connect your application to Supabase.

 

Step 3: Installing the Supabase Client Library

 

Navigate to the package where you'll be using Supabase. Usually, this will be a frontend or backend service in your monorepo. Then install the Supabase client library using your package manager.

cd packages/your-app
npm install @supabase/supabase-js 

 

Step 4: Setting Up Environment Variables

 

Inside the package where you installed Supabase, create an .env file at the root and add your Supabase project's URL and API key.

SUPABASE\_URL=https://xyzcompany.supabase.co
SUPABASE_ANON_KEY=your-anon-public-key

Make sure to add this .env file to your .gitignore to avoid exposing your API keys.

 

Step 5: Initializing Supabase Client

 

Now, create a service file to initialize the Supabase client. This makes it easy to use across your application.

import { createClient } from '@supabase/supabase-js'

const supabaseUrl = process.env.SUPABASE\_URL
const supabaseAnonKey = process.env.SUPABASE_ANON_KEY

const supabase = createClient(supabaseUrl, supabaseAnonKey)

export default supabase

 

Step 6: Using Supabase in Your Application

 

Import the configured Supabase client into your application code where you need to interact with your database.

import supabase from './path-to-your-supabaseServiceFile'

// Example function to get data from a table
async function getData() {
  let { data, error } = await supabase
    .from('your-table')
    .select('\*')

  if (error) console.error('Error fetching data: ', error)
  else console.log('Data: ', data)
}

You can call the getData() function within your application wherever you need to fetch the data.

 

Step 7: Contributing and Collaboration in a Monorepo

 

A key advantage of a monorepo is streamlined collaboration. Use your version control system, such as Git, to branch and manage changes. Others on your team can do the same, allowing for easier code reviews and project management.

 

By following these steps, you'll efficiently set up and utilize Supabase in a monorepo, leveraging all its capabilities with a structured approach.
