Create migration

npm run knex -- migrate:make create-documents

// knex -> new script created
// -- -> signals that the flags used after knex are from knex not regular npm flags
// create-documents -> name of the migration file

Run migration all migrations that have not yet been run

npm run knex -- migrate:latest

After a migration has been sent to production, we must not edit it afterwards. We need to create a new migration to modify it.

If the migration has not been sent to production (it's only on your machine), you can rollback the change, modify the file, and run the migration again.

npm run knex -- migrate:rollback

timestamp

• MySQL => defaultTo('NOW()')
• SQLIte/postgres => defaultTo('CURRENT_TIMESTAMP')

These, don't allow the flexibity to work with any database. An alternative is to use knex.fn.now()

Functional requirements

• User must be able to create a new transaction

• User must be able to see a single transaction

Business logic

• A transaction can be either credit, adding to the total amount, or debit, subtracting the total amount
• [] It must be possible to identify the user between requests
• [] Users can only see the transaction they created

Non-Functional requirements

• TBD
