Tell about your experience using GraphQL in projects.

In Android projects, I used GraphQL to optimize server interactions and reduce the amount of data transmitted. Instead of traditional REST requests, which often retrieve redundant information, GraphQL allows requesting only the fields needed.

For example, when loading a list of users, you can request only the name and avatar without loading unnecessary data:

query {
  users {
    id
    name
    avatarUrl
  }
}

For integration into an Android app, I used the Apollo Client library, which generates type-safe Kotlin code. This simplifies working with requests and responses, and also helps avoid errors during compilation.

GraphQL is also well-suited for projects with frequently changing data requirements, as it allows quickly adapting queries without modifying the server API.
