Go Programming - JSON Encoding & Decoding in Golang

In this video, we look at the utilities offered by Go to work with JSON data.

We'll look at how how to decode JSON data from an API into a Go struct, and we'll also see how to encode a struct to JSON data.

In the video, we'll cover some additional topics, such as the DisallowUnknownFields function, excluding struct fields from being encoded to JSON, and omitting empty values from the encoded JSON data.

Your videos are snappy, clearly delivered, and contain exactly the right amount of additional “extras” like the verbose way to do something and a succinct way to do it. Thank you very much for your quality videos!

wow go is an amazing language and so are your tutorials

It would be nice to see how to store todos in JSON to a NoSql database like clover. And then how to retrieve them.

to clarify: no, when your application exits without you having called defer body.close() you do not have a memory leak (because the application exited so the OS cleans up the resources).

I don't know Go, but always wonder: why not write "if err {" instead of "if err != nil {"
?
