What type of software do you write at your workplace?
https://github.com/json-iterator/go an alternative JSON encoding package which allows to stream (flush out) encoded data as soon as it's able to (which is in contrast with the stock package which buffers everything until the encoding is known to be complete and OK).

Some Go(lang) tips
What to use Easyjson is about the top of the pack and it's straightforward. The downside of efficient tools is that they use code generation to create the code required to turn your structs into json to minimise allocations. This is a manual build step which is annoying. Interestingly json-iterator also uses reflection but it's significantly faster. I suspect black magic.

What are your favorite packages to use?
jsoniter for low level access to JSON encode and decode

What is the best solution to unique data in golang
I think you have to parse the json, if you dont know exactly what you are looking for and want some validation und prevent manual parsing errors. For parsing big json files it is recommend to read and decode it as stream. Here is an example. If you have serious performance criteria take a look at jsoniter. It can be used as 1 to 1 replacement for standard library.
Takes like 10 minutes to write and parses very efficiently. https://github.com/json-iterator/go looks like it can provide such simple parsing

OjG now has a tokenizer that is almost 10 times faster than json.Decode
Need to compare with https://github.com/json-iterator/go too!

What type of software do you write at your workplace?
https://github.com/mitchellh/mapstructure because we have JSON documents which contain rugged arrays ;-)

Help with mapstructure.Decode()
I've been using mapstructure.Decode to great effect, but currently can't figure out why a given mapping doesn't work. I'd appreciate it if someone could point out wtf I'm doing wrong or at least in the right direction:
-
map[string]interface{} decoder
What do you mean by "decode"? I've used https://github.com/mitchellh/mapstructure but that doesn't quite look like what you're doing.
-
Accessing multi-level nested items of a map[string]interface{}
You could use a library made to convert nested maps into structures. https://github.com/mitchellh/mapstructure
-
REST api - returning a field by name from a struct
This package (https://github.com/mitchellh/mapstructure) is similar to encoding/json but encodes/decodes into a map.
-
Go Struct Projection Library
you could also use https://github.com/mitchellh/mapstructure to convert your structs into auxiliary structs that declares the relevant data
- Yaml parsing - mapping to different structure based on property
-
Implement login user API that returns PASETO or JWT access token in Go
First, the TokenSymmetricKey of type string. We have to specify the mapstructure tag for it because viper uses mapstructure package to parse the config data. Please refer to the lecture 12 of the course if you don’t know how to use viper.
-
Unmarshalling json into a struct when a field is SOMETIMES a slice?
Use https://github.com/mitchellh/mapstructure where you can implement a custom field parser using DecodeFieldHook
What are some alternatives?
When comparing jsoniter and mapstructure you can also consider the following projects:
viper - Go configuration with fangs
easyjson - Fast JSON serializer for golang.
compare-go-json - A comparison of several go JSON packages.
go-json - Fast JSON encoder/decoder compatible with encoding/json for Go
go-serializer - :loop: Serialize any custom type or convert any content to []byte or string, for Go Programming Language
goprotobuf - Go support for Google's protocol buffers
gogoprotobuf - [Looking for new ownership] Protocol Buffers for Go with Gadgets
GJSON - Get JSON values quickly - JSON parser for Go
go-codec - idiomatic codec and rpc lib for msgpack, cbor, json, etc. msgpack.org[Go]
