## Getting Started
umzug-hyper-storage is a zero-dependency Storage Adapter for
Umzug that uses a
Hyper Data Service to track
migrations.
It works great as a tool to track and run migrations of your data stored in a
Hyper Data Service. It's also a great generalized script runner, not just for
running migrations.
To instantiate, provide an instance of
[`hyper-connect`](https://github.com/hyper63/hyper/tree/main/packages/connect)
that connects to your data service you would like to use to track your scripts.
```ts
import { Umzug } from 'umzug'
import { HyperStorage } from 'umzug-storage-adapter'
import { connect } from 'hyper-connect'
const hyper = connect(process.env.HYPER)
const umzug = new Umzug({
storage: new HyperStorage({ hyper }),
// optionally pass a hyper-connect instance to each of your scripts
context: {
hyper
}
...
})
await umzug.up() // run migrations
```
This will create a document in your Hyper Data Service in the follow shape:
```js
{
_id: 'hyper-scripts-meta',
type: '__scripts',
migrations: [
// array of scripts that have been ran
],
createdAt: '2022-04-27T20:30:40.688Z',
updatedAt: '2022-04-27T20:30:40.688Z'
}
```
As scripts are ran, their names are appended to the `migrations` array in this
document. If scripts are rolled back, their names are removed from the
`migrations` array, following normal `Umzug` rules.
This is how `Umzug` will track which scripts to run, rollback, or have been
previously executed.
## Documentation
See [Umzug Docs](https://github.com/sequelize/umzug) for Umzug usage.
A [`hyper-connect`](https://github.com/hyper63/hyper/tree/main/packages/connect)
instance connecting to your Hyper Data Service is required upon instantiation.
You may also pass a `doc` argument which dictates the shape of the document
added to hyper data service:
```ts
interface HyperStorageDocArgs {
// the _id of the meta document. Defaults to 'hyper-scripts-meta'
id?: string;
// the type of the meta document. Defaults to '__scripts'
type?: string;
/**
* the field on the meta document to use to store the document type
* ie. 'docType'. Defaults to 'type'
*/
typeField?: string;
/**
* the field on the meta document to store the time
* the meta document was created. Defaults to 'createdAt'
*/
createdField?: string;
/**
* the field on the meta document to store the time
* the meta document was last updated. Defaults to 'updatedAt'
*
* This field is updated each time migrations are ran or rolled back
*/
updatedField?: string;
}
```
### Example using `doc`
```ts
import { Umzug } from 'umzug'
import { HyperStorage } from 'umzug-storage-adapter'
import { connect } from 'hyper-connect'
const hyper = connect(process.env.HYPER)
const umzug = new Umzug({
storage: new HyperStorage({
hyper,
doc: {
type: 'umzug-scripts',
createdField: 'created_at',
updatedField: 'updated_at'
}
}),
...
})
```
### Passing `hyper-connect` to your `Umzug` scripts
Chances are you are running scripts against a Hyper Data Service or
[Hyper Cloud Application Services](https://docs.hyper.io/applications). You can
use [Umzug context](https://github.com/sequelize/umzug#minimal-example) to pass
an instance of `hyper-connect` to each script ran.
By using `context` to _inject_ `hyper-connect`, this will make your scripts
easier to unit test.
```ts
import { Umzug } from 'umzug'
import { HyperStorage } from 'umzug-storage-adapter'
import { connect } from 'hyper-connect'
const hyper = connect(process.env.HYPER)
const umzug = new Umzug({
storage: new HyperStorage({ hyper }),
context: { hyper }
...
})
// then in your script:
const migration = {
name: '01-awesome-migration',
async up ({ context: { hyper }}) {
... // use hyper-connect to perform migration
},
async down ({ context: { hyper }}) {
... // use hyper-connect to perform rollback
}
}
```
