phx.gen.solid

A Phoenix generator for Handlers, Services, Finders, and Values.

Still early in development, some features may be missing. Expect bugs.

Overview

mix phx.gen.solid exists to generate the boilerplate usually required when utilizing the SOLID principles, outlined below. By default it provides fairly general templates for each of the handlers(WIP), services(WIP), finders(WIP), and values. However, all of the templates are completely overrideable.

Installation

After running mix phx.new, cd into your application's directory (ex. my_app).

Basic Installation

1. Add phx_gen_solid to your list of dependencies in mix.exs

   def deps do
     [
       {:phx_gen_solid, "~> 0.3", only: [:dev], runtime: false}
       ...
     ]
   end

2. Install and compile dependencies

   $ mix do deps.get, deps.compile
   

Running the generators

From the root of your phoenix app, you can run the following generators

mix phx.gen.solid.value

This generator will build you a simple Value

$ mix phx.gen.solid.value Accounts User users id slug name

This creates a Value in MyApp.Accounts.Value.User. By default the allowed fields for this value will be the arguments you passed into the generator, in this case, @valid_fields [:id, :slug, :name].

To generate the helpers along with the value:

$ mix phx.gen.solid.value Accounts User users id slug name --helpers

In addition to what gets created above, this will also generate the helpers context with a default name of MyApp.Value.

To override the name of the module where the helpers exist:

$ mix phx.gen.solid.value Accounts User users id slug name --value-context MyApp.Helpers.Value

This will override the name used in the generated value to alias the module given.

mix phx.gen.solid.service

Generates CRUD Services for a resource.

$ mix phx.gen.solid.service Accounts User users id slug name

The first argument is the context module followed by the schema module and its plural name.

This creates the following services:

• MyApp.Accounts.Service.CreateUser
• MyApp.Accounts.Service.UpdateUser
• MyApp.Accounts.Service.DeleteUser
