Database migrations

Those migrations are very similar to the env migrations. The difference is that the data about the migrations are stored in each target databases.

Create migrations

To set up some database migrations in your project, create a migration/db folder at the root of the project. Then you can create any number of JS files in this folder that exports an up function:

// migration/db/201908230224-users.js

// Migration
exports.up = async (context) => {
  // ...

// Rollback
exports.down = async (context) => {
  // ...

The migration functions gets the context as argument.

The migrations will be executed depending on the file name in alphabetical order. Thus it is recommended to use a timestamp as the start of the file name. For example:


Migrations will be applied automatically during any Maintenance.

See an example migration with Knex.
