Simple library to manage database migrations in-memory:

- migration must have a name

- migrations are applied in order, by name (using String.localeCompare to order)

```

npm i migrations-engine --save

```

```ts

import { up, down } from 'migrations-engine';

const all = [

  // these are all available migrations

  {

    name: 'A',

  },

  {

    name: 'B',

  },

];

const applied = [

  // these are all applied migrations so far

  {

    name: 'A',

  },

];

const migrationsToApply = up(applied, all); // [{ name: 'B' }]

// apply migrations

```

The storage and applying of migrations is up to you.
