How Can I Include Lowercase Struct Fields in CouchDB and JSON Using Go?

Exposing Struct Fields in CouchDB and JSON

While utilizing a Go library to access CouchDB, users have encountered an issue where only struct fields starting with capital letters are added to the database or serialized into JSON.

This behavior stems from the Go language's visibility rules. Fields in a struct are only exported, meaning accessible outside the current package, if they begin with capital letters. In the case of JSON encoding and decoding, only exported fields are recognized.

However, it is possible to access non-capitalized fields using JSON tags. By adding tags to a struct field, you can specify the desired JSON key name. For example:

type Sample struct {
    Name string `json:"name"`
    age  int    `json:"age"`
}

In this case, both the "Name" and "age" fields will be serialized into JSON with the keys "name" and "age" respectively. This allows you to have lowercase fields within your struct while still being able to include them in database operations or JSON serialization.
