xo-patcher

Xo patcher is a tool used to generate sql script for bulk data migration.

How it works

• XO : Given the databse connection, we will read all your database schema, And create entites, and repositories for each table.
• Patcher: Write your migration code in golang using entities and repositories created by XO, we will output .sql file containing all your mutation(update/insert) quries.

How to use:

• cd patcher && go mod tidy Install dependencies.
• cp .env.template .env Then update enviroments according to you.
• bash do.sh xo This will generate entities and repositories by reading sql database given in .env file.
• bash do.sh goimports This will fix imports for generated code.
• bash do.sh wire This will perform dependency injection on the generated code.
• touch patches/my-patch.go In this file you can write your patch.
• If you are using vscode type init to use the starup snippet.
• Register the patch in wire_app/wire.go so the patch can be injected in patchManager to be executed.
• bash do.sh runlocal <patch_name> to run the patch, generated .sql file will be placed in \patches_gen.
