Overview of this book

If you're writing applications that move structured data from one place to another, this book is for you. This is especially true if you've been using XML to do the job because it's entirely possible that you could do much of the same work with less code and less data overhead in JSON. While the book's chapters make some distinction between the client and server sides of an application, it doesn't matter if you're a frontend, backend, or full-stack developer. The principles behind using JSON apply to both the client and the server, and in fact, developers who understand both sides of the equation generally craft the best applications.

Introduction


One of the biggest strengths of XML is XPath, the query-oriented language to query subsections of an XML document. Stefan Goessner proposed the JSONPath query language, a language with features similar to XPath that lets you extract just the bits of a JSON document your application needs.

Note that something's still doing the parsing: you don't get something for nothing, and JSONPath implementations require JSON parsing with at least similar memory and runtime characteristics. However, if there's a JSONPath library for the platform you're developing, JSONPath can lead to more readable code, as you don't need to mock entire classes only to extract a field or two or summarize a field across a collection of JSON values.

If you're used to developing for Microsoft platforms, you're certainly aware of Microsoft's Language Independent Query (LINQ) language that lets you use write declarative queries on enumerable data structures. While the .NET implementations of JSON parsing provide...
