when using go for web development, orm can establish mappings between business objects and databases, but there is no library similar to dto in java, which can make a layer of isolation between the presentation layer and business objects.
for example, if I want to query all candidate and return it to the front end as json, then I must do this:
type Candidate struct {
Address string `bson:"address" json:"address"` // owner
PubKey string `bson:"pub_key" json:"pub_key"`
Shares int64 `bson:"shares" json:"shares"`
VotingPower uint64 `bson:"voting_power" json:"voting_power"` // Voting power if pubKey is a considered a validator
Description Description `bson:"description" json:"description"` // Description terms for the candidate
}however, this is coupling the UI object with the business object, which is somewhat unreasonable in terms of design and development. So, I would like to ask if there is a library similar to dto in the go language to do a layer of separation?
