jsonquery is a Go library that allows you to parse and extract data from JSON documents using JSONPath expressions. JSONPath is similar to XPath, but it is designed specifically for working with JSON documents.

The jsonquery library allows you to traverse the JSON tree structure and extract values using JSONPath expressions. It provides a simple and intuitive API for querying the JSON data, and it is built on top of the popular jsoniter library.

Example Use


package main

import (
  "fmt"
  "log"

  "github.com/antchfx/jsonquery"
)

func main() {
  // Parse the JSON string
  doc, err := jsonquery.Parse([]byte(`
    {
      "name": "John Doe",
      "age": 30,
      "address": {
        "street": "Main St",
        "city": "Anytown",
        "state": "CA",
        "zip": "12345"
      },
      "phones": [
        "555-555-5555",
        "555-555-5556"
      ]
    }
  `))
  if err != nil {
    log.Fatal(err)
  }

  // Extract the name
  name := jsonquery.FindOne(doc, "name")
  fmt.Println(name.InnerText())  // "John Doe"

  // Extract the city
  city := jsonquery.FindOne(doc, "address.city")
  fmt.Println(city.InnerText())  // "Anytown"

  // Extract all phone numbers
  phones := jsonquery.Find(doc, "phones[*]")
  for _, phone := range phones {
    fmt.Println(phone.InnerText())
  }
  // "555-555-5555"
  // "555-555-5556"
}
