Golang JSON Programs ». If you are like me and want to learn backend development, you probably came across JSON handling at one point. JSON is a very popular format for transferring data between the front and backend. Because it is such an essential feature in modern web development, Golang adds support for JSON in its encoding/json package. In late August 2022, Jonathan Amsterdam of the Go team initiated a discussion with the community about adding structured, log-level support for logging packages to the Go standard.

The json package offers NewEncoder and NewDecoder functions which would get us Encoder and Decoder types. These types can work with other objects that support io.Reader and io.Writer interfaces to offer streaming support. Streaming JSON from a File We can open a JSON file using the os.Open function and stream it using the json.NewDecoder function.

There are two steps when manipulating JSON with Go’s self-contained encode/json package. Define the mapping. That is, mapping the field from struct to the corresponding JSON.

Field int `json:"-,"`. The "string" option signals that a field is stored as JSON inside a JSON-encoded string. It applies only to fields of string, floating point, integer, or boolean types. This extra level of encoding is sometimes used when communicating with JavaScript programs: Int64String int64 `json:",string"`.. We can extend this approach and use the same encoders / decoders on a JSON file. However, since we'll need to read from a file, we can use the io/ioutil package too. Let's assume a simple file config.json, having the following content: 1 2 3 4 5 { "origin": "golangdocs.com", "user": "Vijay", "active": true }.
