v4.2.x to v4.3.x migration guide

The Strapi v4.2.x to v4.3.x migration guide upgrades versions of v4.2.x and above to v4.3.x. This migration guide is needed for all TypeScript users who are using the default SQLite database configuration in their application. The migration to 4.3.3 consists of 3 steps:

  • Upgrading the application dependencies
  • Updating the database configuration script
  • Reinitializing the application

Upgrading the application dependencies to 4.3.x​

Stop the server before starting the upgrade. At the time of writing this, the latest version of Strapi is v4.3.3.

  1. Upgrade all of the Strapi packages in the package.json to 4.3.3 or higher:
path: ./package.json

{
  // ...
  "dependencies": {
    "@strapi/strapi": "4.3.3",
    "@strapi/plugin-users-permissions": "4.3.3",
    "@strapi/plugin-i18n": "4.3.3",
    // ...
  }
}

  1. Save the edited package.json file.

Updating the database configuration script​

This step is only required if you use the default SQLite database configuration in a TypeScript project.

To make sure you don't lose your data every time the development server restarts, you need to make a modification to the ./config/database.ts file. This modification tells Strapi to use the correct file for your database.

To change the script:

  1. In the ./config/database.ts file, Identify the default SQLite database configuration.
  2. Copy and paste the following line to the replace the filename key of the SQLite configuration:
path: ./config/database.ts
filename: path.join(__dirname, '..', '..', env('DATABASE_FILENAME', '.tmp/data.db')),

Rebuild the application​

Restart the application​
