## Repo

| byGrok                | **Monolith**                  | **Monorepo**                           | **Polyrepo** (Multi-repo)    |
| --------------------- | ----------------------------- | -------------------------------------- | ---------------------------- |
| **Definition**        | Single deployable application | Single Git repository                  | Multiple Git repositories    |
| **Code organization** | One codebase, tightly coupled | Multiple projects/packages in one repo | One project/package per repo |

**Quick rule of thumb**

* **Monolith** → simple app, early stage
* **Monorepo** → many related projects that share a lot of code
* **Polyrepo** → independent projects/teams/services

## GraphQL

<http://graphql.org/\\>
a query language and execution engine tied to any backend service.

```
enum Episode { NEWHOPE, EMPIRE, JEDI }

interface Character {
    id: String
    name: String
    friends: [Character]
    appearsIn: [Episode]
}

type Human implements Character {
    id: String
    name: String
    friends: [Character]
    appearsIn: [Episode]
    homePlanet: String
}
```
