# Data Client for GraphQL > @data-client/graphql: GraphQL endpoints and schemas for Reactive Data Client. Its full docs, with framework hooks, are in the framework llms.txt files. Package: @data-client/graphql. Using React? See https://dataclient.io/llms.txt Using Vue? See https://dataclient.io/vue/llms.txt To add Data Client to an app, run `npx skills add reactive/data-client --skill data-client-setup -y` from the project root, then read `.agents/skills/data-client-setup/SKILL.md` and follow it. If the app already has it, run `npx --no data-client-skills` from the project root to link the agent skills it ships into `.agents/skills`. ## GraphQL - [GraphQL Usage with Reactive Data Client](https://dataclient.io/graphql.md) - [GraphQL Authentication patterns for Reactive Data Client](https://dataclient.io/graphql/auth.md) ## GraphQL › GraphQL API - [GQLEndpoint](https://dataclient.io/graphql/api/GQLEndpoint.md) - [GQLEntity](https://dataclient.io/graphql/api/GQLEntity.md)
