Chanson

Package chanson provides a flexible way to construct JSON documents. As chanson populates Arrays and Objects from functions, it's perfectly suitable for streaming jsons as you build it. It is not an encoder itself, by default it relies on json.Encoder but its flexible enough to let you use whatever you want.

Example

package main

import (
	"bytes"
	"fmt"

	"github.com/gchaincl/chanson"
)

func main() {
	ch := make(chan int)
	go func() {
		ch <- 1
		ch <- 2
		ch <- 3
		ch <- 4
		close(ch)
	}()

	buf := bytes.NewBuffer(nil)
	cs := chanson.New(buf)
	cs.Array(func(a chanson.Array) {
		for i := range ch {
			a.Push(i)
		}
	})

	fmt.Printf("%v", buf.String())
}
