A Practical Beginner&#8217;s Tutorial<\/h1>\n<p>GraphQL is a query language and server-side runtime for APIs, released by Facebook in 2015. Instead of calling many fixed endpoints, a client sends one request describing exactly the fields it needs, and the server returns only that data. It is transport-agnostic and typically served over a single HTTP endpoint.<\/p>\n<h2>GraphQL vs. REST<\/h2>\n<p>REST exposes many URLs, each returning a fixed shape. That causes over-fetching (extra fields) or under-fetching (extra round trips). GraphQL exposes one endpoint backed by a typed schema, so clients ask for precisely what they want\u2014fewer requests and predictable responses.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/sumberlaba.com\/wp-content\/uploads\/2026\/10\/article-1792386057467.jpg\" alt=\"Article illustration\" style=\"display:block;margin:20px auto;max-width:100%;height:auto;border-radius:8px;\" \/><\/p>\n<h2>The Core Building Blocks<\/h2>\n<ul>\n<li><strong>Schema:<\/strong> a typed contract defining every query and type.<\/li>\n<li><strong>Query:<\/strong> a read request shaped like the response.<\/li>\n<li><strong>Mutation:<\/strong> a write operation.<\/li>\n<li><strong>Resolver:<\/strong> a function that fetches data for each field.<\/li>\n<\/ul>\n<h2>A Five-Minute Example<\/h2>\n<p>A simple query looks like <code>query { user(id: 1) { name posts { title } } }<\/code>. The server walks the resolvers, gathers the user and their posts, and returns JSON matching the query exactly.<\/p>\n<h2>When to Use It<\/h2>\n<p>GraphQL shines with mobile clients, fast-changing UIs, and multiple data sources. It adds complexity\u2014caching, rate limiting, and query depth limits need attention\u2014so simple CRUD APIs may still be better served by REST.<\/p>\n<h2>Conclusion<\/h2>\n<p>GraphQL is not a database or a REST replacement, but a flexible query layer. Start with one endpoint, define a small schema, and grow from there.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What Is GraphQL?
