This information is crucial because it allows you to make informed decisions to improve your website. Google Analytics is a great choice but there could be data privacy as well as GDPR compliance concerns. When choosing an analytics tool, it's important that it: - is free (open source) - allows self hosting (no vendor lock in) - is GDPR compliant - is light weight & fast Umami Analytics checks all these boxes. ### Umami Analytics : An open source analytics solution [Umami Analytics](https://umami.is/docs) is a simple, fast, and privacy-focused tool that lets you track website usage without compromising user privacy. It is an open-source alternative to Google Analytics. A big plus is that Umami analytics is GDPR (General Data Protection Regulation) compliant. There are two options to use UMAMI analytics - use UMAMI cloud solutions (paid with free tier plan) - Self host on your server In this article we are going to explore self hosting option. We are going to use Supabase (free tier plan) for database (postgres) and Vercel (free tier/hobby plan) for hosting Umami. Let us dive into how to self host Umami analytics using Vercel + Supabase for free ### 1\. Create new project in Supabase - Create a new account (if you don’t already have one) with Supabase and create new project by pressing `+ New Project` - Provide project name as you like (eg. `your_app_name-analytics`) - Don’t forget to store password somewhere, it would be needed later. - Select a region nearest to the location of hosting server. ### 2\. Initial Configuration for Supabase - Select the project, navigate to SQL editor - Copy the SQL scripts provided in the [github](https://github.com/umami-software/umami/blob/master/db/postgresql/migrations/01_init/migration.sql) repo - Paste it on the SQL editor and click on run - You’ll be able to see newly created tables on `Table Editor` option - Navigate to Project Settings → Database → Connection String → Copy Connection URL ### 3\. Fork UMAMI on github - Fork the [https://github.com/umami-software/umami](https://github.com/umami-software/umami) project to your GitHub account. - Edit `db/postgresql/schema.prisma` file (add directUrl) ``` datasource db { provider = "postgresql" url = env("DATABASE_URL") directUrl = env("DIRECT_DATABASE_URL") //add this line relationMode = "prisma" } ``` ### 4\. Deploy on Vercel - Go to Dashboard on Vercel and create new project - From the dashboard page click Import Project then specify the URL to your fork of the project on GitHub. - Before clicking on Deploy add the following environment variables ``` DATABASE_URL = postgres://[user]:[password]@aws-0-[aws-region].pooler.supabase.com:6543/postgres?**pgbouncer=true&connection_limit=1** DIRECT_DATABASE_URL = postgres://[user]:[password]@aws-0-[aws-region].pooler.supabase.com:**5432**/postgres ``` Enter fullscreen mode Exit fullscreen mode ### Important!! 💡 DATABASE\_URL is same as the Connection Url copied from supabase (in step 2) but you have to add **`?pgbouncer=true&connect_timeout=1`** at the end of Url 💡 DATABASE\_URL is same as the Connection Url copied from supabase (in step 2) but you have to replace the port from `6543` to `5432` - After that click on deploy ### 5\. Resolving Error “The database Schema is not empty” - In step two we did run a sql script in Supabase which created few tables in the database. Now when script is run during deployment it throws an error with error code `P3005` saying `Database schema is not empty` - To resolve this, clone your forked repository in your local and add the same environment variables as mentioned above (in step 4) - Now run the following commands (to install dependencies and setup db connection) ``` yarn install yarn build-db ``` - Then we would create a [baseline migration](https://www.prisma.io/docs/orm/prisma-migrate/workflows/baselining) by following below steps 1. If you have a prisma/migrations folder, delete, move, rename, or archive this folder. 2. Run the following command to create a `migrations` directory inside with your preferred name. This example will use `01_init` for the migration name: ``` mkdir -p prisma/migrations/01_init ``` 3. Generate a migration and save it to a file using `prisma migrate diff` ``` npx prisma migrate diff \ --from-empty \ --to-schema-datamodel prisma/schema.prisma \ --script > prisma/migrations/01_init/migration.sql ``` 4. Run the `prisma migrate resolve` command for each migration that should be ignored: ``` npx prisma migrate resolve --applied 01_init ``` This command adds the target migration to the `_prisma_migrations` table and marks it as applied. When you run `prisma migrate deploy` to apply new migrations, Prisma Migrate: 1. Skips all migrations marked as 'applied', including the baseline migration 2. Applies any new migrations that come after the baseline migration - You will be able to successfully deploy the app on Vercel server after this. The URL of your analytics app would be available under `project` tab of Vercel app. ### 6\. Login to Umami - The default credentials for login is ``` username : admin password : umami ``` Enter fullscreen mode Exit fullscreen mode - To change the default credentials navigate to settings → users → admin → edit - Enter your new password and click on save. ### 7\. Configure your website for analytics tracking - navigate to settings → websites → `+ Add website` ``` Name : provide any name of your choice Domain : your [website](https://www.invoizly.com) domain (eg. invoizly.com) ``` Enter fullscreen mode Exit fullscreen mode - Once website is added navigate to settings → website → your website name → edit → tracking code. Copy the tracking code. ### 8\. Add tracking code to your project In Next.JS projects to load a [third-party script](https://nextjs.org/docs/app/building-your-application/optimizing/scripts) for multiple routes, import `next/script` and include the script directly in your layout component: ``` import Script from 'next/script' export default function Layout({ children, }: { children: React.ReactNode }) { return ( {children}
