Changing Databases: From SQLite to PostgreSQL

A lot of us, myself included, start off with SQLite for its simplicity and ease of setup. However, migrating to PostgreSQL often becomes necessary as projects grow in complexity. Here’s a step-by-step approach on how you can do this conversion seamlessly.

Understanding the Migration Necessity

First, it’s important to understand why you might want to change your database. PostgreSQL offers improvements over SQLite, such as:

• Scalability: Handles larger volumes of data more efficiently.
• Concurrency: Better support for concurrent transactions.
• Data Integrity: Advanced features for maintaining data accuracy.

Step-by-Step Migration Process

Now, let me share the steps I used to move from SQLite to PostgreSQL:

1. Back Up Your SQLite Data: Use a tool like sqlite3 to back up your current data.

   sqlite3 mydatabase.db .dump > dump.sql

   1 2 3 4

   sqlite3 mydatabase.db .dump > dump.sql

2. Set Up PostgreSQL: Create a new database on your PostgreSQL server.

3. Install Required Packages: You may need additional packages to support PostgreSQL in Strapi:

   npm install pg pg-hstore

   1 2 3 4

   npm install pg pg-hstore

4. Configure Database Settings: Update your database.js configuration file in Strapi’s config folder.

   module.exports = { defaultConnection: 'default', connections: { default: { connector: 'bookshelf', settings: { client: 'postgres', host: 'localhost', port: 5432, database: 'mydb', username: 'myuser', password: 'mypassword', }, options: { ssl: false, }, }, }, };

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

   module.exports = {   defaultConnection: 'default',   connections: {     default: {       connector: 'bookshelf',       settings: {         client: 'postgres',         host: 'localhost',         port: 5432,         database: 'mydb',         username: 'myuser',         password: 'mypassword',       },       options: {         ssl: false,       },     },   }, };

5. Migrate Data: Convert your SQLite data to PostgreSQL using a specialized tool or script. There are several online converters or scripts that can assist in this task.

6. Rebuild the Project: Run the following command to apply the new database configuration.

   strapi start

   1 2 3 4

   strapi start

This process might seem overwhelming, but taking it step-by-step really breaks down the complexity.
