+# Assignment: Graphql Service
+
+## Description
+
+Imagine we have a couple of microservices that is created for the service Musicify, a new wikipedia for Music. We need to provide a confortable and convinient service for our users for managing and retrieving data for different entities.
+
+The following entities exists:
+
+```typescript
+interface Artist {
+    _id: string;
+    firstName: string;
+    secondName: string;
+    middleName: string;
+    birthDate: string;
+    birthPlace: string;
+    deathDate: string;
+    deathPlace: string;
+    country: string;
+    bandsIds: string[]
+    instruments: string[];
+    pseudonims: string[]
+    labels: string[];
+}
+```
+
+```typescript
+interface User {
+    _id: string;
+    firstName: string;
+    secondName: string;
+    middleName: string;
+    password: string;
+    email: string;
+}
+```
+
+```typescript
+interface Band {
+    _id: string;
+    name: string;
+    origin: string;
+    yearsActive: string[];
+    labels: string[];
+    membersIds: string[];
+    pastMembers: string;
+    website: string;
+    genresIds: string[];
+    logo: string;
+}
+```
+
+```typescript
+interface Genre {
+    _id: string;
+    name: string;
+    description: string;
+    country: string;
+    year: string;
+    subGenresIds: string[];
+}
+```
+
+```typescript
+interface Track {
+    _id: string;
+    artists: Artist[];
+    bands: Band[];
+    year: number;
+    albumId: string;
+    name: string;
+    description: string;
+    lyrics: string;
+    length: number;
+    authorsIds: number; 
+}
+```
+
+
+**Details:**
+
+1. For each entity there is a separate microservice, you can find all microservices in corresponding repositories:
+
+    - Artists service
+    - Users service
+    - Bands service
+    - Genres service
+    - Tracks service
+    - Favourites service
+
+The instruction how to launch it you can find in service readme.md.
+
+2. The Following types should be created:
+
+```graphql
+type Artist {
+    id: ID!
+    firstName: String
+    secondName: String
+    middleName: String
+    birthDate: String
+    birthPlace: String
+    deathDate: String
+    deathPlace: String
+    country: String
+    bands: String
+    instruments: String
+    pseudonims: String
+    labels: String
+}
+
+```
+```graphql
+type Artist {
+    id: ID!
+    name: String
+    origin: String
+    yearsActive: String
+    labels: String
+    members: [Member]
+    pastMembers: String
+    website: String
+    genres: String
+    logo: String
+}
+
+```
+```graphql
+type Genre {
+    id: ID!
+    name: String
+    description: String
+    country: String
+    year: Int
+    subGenres: [Genre]
+}
+
+```
+
+type Favourites {
+id: ID!
+name: String
+description: String
+country: String
+year: Int
+subGenres: [Genre]
+}
+
+3. The following queries ahould be created:
+
+- artist
+- artists
+- genre
+- genres
+- track
+- tracks
+- band
+- bands
+- favourites (available only for logged in user)
+
+The following mutation should be created:
+
+- createArtist
+- deleteArtist
+- updateArtist
+- createGenre
+- deleteGenre
+- updateGenre
+- createBand
+- deleteBand
+- updateBand
+- createTrack
+- deleteTrack
+- updateTrack
+- addTrackToFavourites
+- addBandToFavourites
+- addArtistToFavourites
+- addGenreToFavourites
+
+**Mutation requests must be available only for logged in users.**
+
+4. Service port should be configured through env variable.
+
+5. Each entity must have a separate module.
+
+```
+- app
+    -modules
+        - bands
+        - artists
+        - tracks
+        - genres
+        - favourites
+```
