I have a ndjson (newline delimited JSON) file, I need to parse it and get the data for some logical operation. Is there any good method for parsing ndjson files using golang. A sample ndjson is given below
{"a":"1","b":"2","c":[{"d":"100","e":"10"}]}
{"a":"2","b":"2","c":[{"d":"101","e":"11"}]}
{"a":"3","b":"2","c":[{"d":"102","e":"12"}]}
The encoding/json Decoder parses sequential JSON documents with optional or required whitespace depending on the value type. Because newlines are whitespace, the decoder handles ndjson.
d := json.NewDecoder(strings.NewReader(stream))
for {
// Decode one JSON document.
var v interface{}
err := d.Decode(&v)
if err != nil {
// io.EOF is expected at end of stream.
if err != io.EOF {
log.Fatal(err)
}
break
}
// Do something with the value.
fmt.Println(v)
}
