# graphql-nodejs-concept
Understanding GraphQL sometimes hard and confusing. That's why I create this simple project (using minimal framework and using array to represent a database). The goal is simple, to get idea about what is GraphQL and what GraphQL can do.
In this imaginary project let say we have data of `artists` and `songs`. Songs have relation to artists.
All logic is on `index.mjs` file, so it should be simple.
After we understand about GraphQL, I think will be easy later if we want to replace the data layer with real connection to database.
## Libraries and tools used (see on `package.json`)
- `graphql`, as JS reference implementation for GraphQL.
- `graphql-yoga`, as GraphQL server.
- `nodemon`, just a tool that helps develop Node.js based applications by automatically restarting the node application when file changes in the directory are detected.
## Sample data
```js
const dataArtists = [
{ id: 1, name: "Peter Cetera" },
{ id: 2, name: "Dewa 19" },
{ id: 3, name: "Tito Soemarsono" },
{ id: 4, name: "Natalie Imbruglia" },
{ id: 5, name: "David Foster" },
{ id: 6, name: "Kahitna" },
]
const dataSongs = [
{ id: 1, title: "One Clear Voice", artistId: 1 },
{ id: 2, title: "Kangen", artistId: 2 },
{ id: 3, title: "Diam-diam", artistId: 3 },
{ id: 4, title: "Torn", artistId: 4 },
{ id: 5, title: "The Best of Me", artistId: 5 },
{ id: 6, title: "Cantik", artistId: 6 },
{ id: 7, title: "Cerita Cinta", artistId: 6 },
]
```
## Query methods
- `songs`, to get all songs
- `song`, to get particular song by id
- `artists`, to get all artists
- `artist`, to get particular song by id
## Mutation methods
- `addSong`, to add new song to array
- `updateSong`, to update particular song by id
- `deleteSong`, to delete particular song by id
- `addArtist`, to add new artist to array
- `updateArtist`, to update particular artist by id
- `deleteArtist`, to delete particular artist by id
## Screenshot
## How to run?
- Clone the repository
- Go to the project folder
- Run `npm install`
- Run `npm run dev`
A web server will run on `localhost:5000`.
You can go to `http://localhost:5000/graphql` it will show the GraphiQL Yoga screen. You can try query there, let type the sample below.
```graphql
query {
artists {
id
name
songs {
id
title
}
}
}
```
It will get list of all `artists` data.
