Relay Result is a tiny layer on top of Relay's libraries to add type-safe payloads for GraphQL mutations.
Relay Result is a tiny layer on top of Relay's libraries to add type-safe payloads for GraphQL mutations.
Example of the generated types:
union UserLoginPayload = UserLoginSuccess | UserLoginError
type UserLoginSuccess {
user: User!
clientMutationId: String
}
type UserLoginError {
error: String!
clientMutationId: String
}
input UserLoginInput {
"""
Email of the user attempting to log in
"""
email: String!
"""
Password of the user attempting to log in
"""
password: String!
clientMutationId: String
}
