* IntelliJ Kotlin code generator for Retrofit2 and RxJava2 based on Swagger *

Protein is a plugin for intelliJ that automates the build of Retrofit "Interfaces" and "models" for Android in Kotlin. It generates the code for Retrofit based on a Swagger endpoint.

Background

Protein: A large molecule composed of one or more chains of amino acids in a specific order; the order is determined by the base sequence of nucleotides in the gene coding for the protein. Proteins are required for the structure, function, and regulation of the body’s cells, tissues, and organs, and each protein has unique functions. Examples are hormones, enzymes, and antibodies.

This scientific definition defines quite good the objective of this Plugin in an abstract way. For many time at Adevinta Spain we struggled with the idea of making a good and maintainable architecture for Android. It's been some time until we got one that fits with our needs but we still have a lot of errors and issues that human beings do every time we make manual work. That's were we came to the idea of automatization and make new components with all we need.

Protein is our approach to work better, be more productive and reliable.

NOTE: Protein is based on the library Retroswagger that is the core for the kotlin builder that parses swagger json and generates the kotlin code.

Features

Easy interface
Interface and Models auto-generated
Swagger integration: create code based on swagger documentation
IntelliJ and Android Studio compatible

Requirements

To use it you need a Swagger schema endpoint (example: http://petstore.swagger.io/v2/swagger.json).

Example

Retrofit2 + RxJava2 Interface generated in Kotlin

It will generate the interface and the models related to that interface.

package com.mycompany.mylibrary

import io.reactivex.Completable
import io.reactivex.Single
import retrofit2.http.DELETE
import retrofit2.http.GET
import retrofit2.http.PUT
import retrofit2.http.Path

interface componentNameApiInterface {
    @GET("/favorites")
    fun getFavorites(): Single<GetFavoritesResponse>

    @PUT("/favorites/{adId}")
    fun saveFavorite(@Path("adId") adId: String): Completable

    @DELETE("/favorites/{adId}")
    fun deleteFavorite(@Path("adId") adId: String): Completable
}
