Over time any software project will get larger, and with laravel projects this often means that the migrations folder can get very large. In laravel 8 the schema:dump command was introduced to clean this up a bit, and instead of running possibly hundreds of migration files when migrating using migrate:fresh, the schema:dump command can run just 1 schema file containing the schema of all the migrations up until that point. You will need the mysqldump command available as an environment variable as a prerequisite.
First run the schema:dump command: You sh ould now see in /database/schema there is a new file called mysql-schema.sql.
You could run the command again to delete all these unnecessary migration files now: Now you have a new starting point for your migrations, any new migrations will first run the mysql-schema.sql file, and then run all the migrations that came after.
