jsons is a Go library to work with JSONS/NDJSON files.
JSONS files contain JSON objects, one per line. This storage format is more efficient than storing an array of objects since it doesn’t need to be loaded in memory when reading/writing it.
go get github.com/bfontaine/jsons
func read() {
j := jsons.NewFileReader("foo.jsons")
if err := j.Open(); err != nil {
log.Fatal(err)
}
defer j.Close()
for {
var m map[string]string
if err := j.Next(&m); err != nil {
if err == io.EOF {
break
}
log.Fatal(err)
}
log.Printf("got %+v", m)
}
}func write() {
j := jsons.NewFileWriter("foo.jsons")
if err := j.Open(); err != nil {
log.Fatal(err)
}
defer j.Close()
j.Add(map[string]string{
"foo": "bar",
"qux": "abc",
})
j.Add(map[string]string{
"foo": "def",
"ghi": "jkl",
"mno": "qpr",
})
