Pretty-print GraphQL queries, mutations and schemas: the parser understands the GraphQL syntax (fields, arguments, variables, fragments, directives, type definitions) and re-emits them with consistent indentation.
Unlike a JSON formatter, GraphQL is not nested braces — its layout conventions (inline arguments, named fragments, block strings) need a grammar-aware printer, which is what this runs.
Frequently asked questions
Does it validate the query?
It parses, so syntax errors are caught and reported at their position; semantic validation (does the field exist on that type) needs the schema, which stays on your server.
Will reformatting change my query?
No — only whitespace and line breaks. The printed query is semantically identical to the pasted one, character for character where it matters.
中文说明
美化 GraphQL 查询、变更与 schema：解析器理解 GraphQL 语法（字段、参数、变量、片段、指令、类型定义），按一致的缩进重新输出。
与 JSON 格式化不同，GraphQL 不是嵌套大括号——它的排版惯例（内联参数、命名片段、块字符串）需要感知语法的打印机，本工具运行的就是它。
常见问题
它校验查询吗？
它做解析，语法错误会被捕获并指出位置；语义校验（某类型上是否存在该字段）需要 schema，那留在你的服务器上。
重新排版会改变查询吗？
不会——只改空白与换行。输出的查询与粘贴的语义完全一致，关键处逐字符相同。
