## Description
AIRport allows Distributed Applications to interoperate by providing an API
framework on top of a relational database. Data is stored in virual
Repositories with one Transaction Log per repository.
More documentation can be found at [Beyond Decentralized](https://github.comhttps://beyond-decentralized.world/documentation.html).
## How it works
* User navigates to a web page and saves/retrieves data.
* A new tab is opened in the background with AIRport framework in it
* AIRport contacts Transaction Log data hosts (Ex: IPFS), retrieves data,
puts into in-memory SqLite database, queries it, makes modifications to it,
writes the Transaction Log entries back to data hosts.
* Access to database is allowed only from App logic that runs in
domain-sanboxed IFrames (inside AIRport tab).
## Build instructions
If something isn't building and it really should, run 'rush update'
Check out [AIRroot](https://github.comhttps://github.com/beyond-decentralized/AIRroot) for framework build instructions.
## Entity Definitions
```typescript
@Entity()
export class Parent extends AirEntity {
value: string;
total: number;
@OneToMany({mappedBy: 'parent'})
children: Child[];
}
@Entity()
export class Child extends AirEntity {
value: string;
@ManyToOne()
parent: Parent;
}
```
## Queries
Apps can define entities which depend on entities in other
Apps, via @ManyToOne() relations. Apps can build joins that include
entities from other Apps.
## Data Access Objects (DAOs)
```typescript
@Injected()
export class ParentDao
extends BaseParentDao {
async findById(
parentUuId: string
): Promise
{
let p: QParent,
c: QChild
return await this._findOne({
SELECT: {
'*': Y,
children: {}
},
FROM: [
p = Q.Parent,
c = p.children.LEFT_JOIN()
],
WHERE: p.equals(parentUuId)
})
}
async updateInPlace(
parent: Parent
): Promise {
const p: QParent
await this._updateWhere({
UPDATE: p = Q.Parent,
SET: {
total: PLUS(p.total, 1)
},
WHERE: p.equals(parent)
})
}
}
```
## APIs
Public API methods are annotated with @Api() decorator. Apps can
invoke @Api() methods of other Apps. Apps can join across
application schemas but must call APIs of other Apps to modify
their data.
```typescript
@Injected()
export class ParentApi {
@Inject()
parentDao: ParentDao
@Api()
async save(
parent: Parent
): Promise {
await this.parentDao.save(parent)
}
@Api()
async findById(
parentUuId: string
): Promise {
return await this.parentDao.findById(parentUuId)
}
}
```
