Demonstration on how to use GraphQL with Node and Vue in bits

GraphQL is presented as a powerful alternative to REST for building APIs, offering a single route system that allows clients to request exactly what they need, thereby reducing unnecessary data transfer and making API evolution more manageable. Unlike REST, which requires multiple endpoints and HTTP verbs, GraphQL provides a complete description of the data, supports interactive API documentation, and does not necessitate API versioning. The article explores key components of GraphQL, such as types, queries, mutations, and resolvers, and demonstrates their implementation in a project using Apollo with Node.js and Vue.js. Authentication is handled at the resolver level, where JWT tokens are used to secure requests, while file uploads are facilitated through Apollo's built-in support. The article concludes by highlighting the ease of setting up, updating, and refactoring GraphQL compared to REST, emphasizing the importance of well-designed schemas to prevent recursive calls and redundant queries.
