On this tale, I wish to display you find out how to deliver your Ruby on Rails building to the following stage.
Like regularly in programming, all it takes is automating repetitive stuff.
One job that begs for automation within the Ruby on Rails building is beginning new tasks.
If from day one you care about:
- Code high quality,
- Simple upkeep,
- Just right functionality,
- Code that is delightful to paintings with,
then you could have come to the fitting position – let’s examine why.
All these things we want…
Starting new Ruby on Rails undertaking is like:
No, significantly – such a lot stuff to do:
- Set up the newest strong Ruby model – take a look at.
- Set up the newest strong Ruby on Rails model – take a look at.
- Set up the newest strong database model: MySQL, PostgreSQL, you identify it – take a look at.
- Get ready : Rails credentials, Dotenv, Figaro – take a look at.
- Create a brand new git faraway repository: , , Bitbucket – take a look at.
- Set up the newest strong Redis model – take a look at.
- in building to – take a look at
- Async code execution, like Sidekiq – take a look at.
- Create a brand new undertaking on the tracking cloud: , , Honeybadger, Bugsnag, Airbrake, Skylight – take a look at.
- – take a look at.
- – take a look at.
- – take a look at.
- , and take a look at now not forgetting any of the next: DatabaseCleaner, FactoryBot, TimeCop, Rspec Sidekiq Trying out, VCR – take a look at.
- Oh yeah, code protection with SimpleCov and Coveralls – yeah, I forgot when speaking about RSpec – take a look at.
- , Fasterer, Brakeman, Dawnscanner, Package Audit, Rails Perfect Practices – take a look at.
- Arrange this entire standardized-code-Third-reich within the Steady Integration – Github Movements, , Bamboo, , Travis – take a look at.
Rattling, that is a handful.
Now, take a look at for instance not to stay the bar up from the primary devote, and any person will take a crap in the midst of your code base – thankfully.
, yeah I heard”.
Or, let’s skip logging mistakes and depart the default logger handiest. Then sign up the MVP blindfolded.
And.. have you ever spotted? Now not a phrase but about:
- Deployment, to not point out a Steady Supply and
Do not get me improper, I really like Ruby on Rails, it is nonetheless my favourite – such a lot stuff out of the field.
Simply all this configuration is what, like two, three workdays?
Default Ruby on Rails choices
, we’re in a position to inform Rails to do / don’t use sure portions of the framework.
And there is a handful to keep in mind, as you’ll be able to see.
In the event you already constructed some Ruby on Rails apps, if in case you have a listing of choices you do not like, or you are within the PostgreSQL or MySQL camp.
If that is the case, you’ll be able to outline the magic ~/.railsrc record in your house listing, with initialization flags that you simply at all times use.
contact ~/.railsrc vi ~/.railsrc
For instance, my seems like this:
--database=postgresql --skip-spring --skip-test --webpack=react --template=https://hixonrails.com/template.rb
command on my gadget:
- pass Postgres!
- nope Spring
- nope MiniTest, I would like RSpec
- pass React!
Ruby on Rails – Application Template
You’ll be able to upload stuff to the new Ruby on Rails undertaking – initializers, gemstones, rake duties – you identify it.
rails new undertaking --template /trail/to/template.rb rails new undertaking --template https://instance.com/template.rb
Easy, but so robust.
The template code runs after the preliminary Rails configuration, and prior to the package installs.
That signifies that you’ll be able to:
- Override each and every record generated
- Upload any gemstones you need
- Create new recordsdata
- Create database tables
On best of that, you’ll be able to run any shell command.
For instance: create a faraway git repository by means of Github or Gitlab API.
Afterwards upload the git faraway to the undertaking.
Let’s now take a snappy glance what we will do the usage of Rails App Template explicit language:
- Set up and crew gemstones through environments with
- Claim gem resources with
- Write to declared
- Acquire consumer enter with
strategies and run different stuff conditionally
- Release rails
for scaffold, migration, fashion, controller, no matter
- Explicitly run decided on code
- Execute shell instructions with the
That is numerous helpful stuff proper right here, so let’s examine it in motion.
Rails Application Template with static code research
Let’s give one of the most application template strategies a spin through putting in a truly easy Rails Application Template, that:
- Installs and makes use of RuboCop through default
- Installs and calls for RuboCop Efficiency extension
- Installs and calls for RuboCop Rails extension
So here is how to try this.
First, let’s create our template.rb record and open it with a textual content editor.
# frozen_string_literal: true gem_group :building, :verify do gem 'rubocop' gem 'rubocop-performance' gem 'rubocop-rails' finish
Now that we have got the ones in position, let’s inform Rails so as to add the .rubocop.yml record, so we will unfastened up those Ruby nazi a bit.
Upload the next code.
record '.rubocop.yml', <<-CODE require: - rubocop-rails - rubocop-performance AllCops: Exclude: - node_modules/**/* - db/** - db/migrate/** - bin/** - dealer/**/* Format/LineLength: Max: 120 Metrics/BlockLength: Exclude: - config/**/* Taste/Documentation: Enabled: false CODE
That is going to jot down our RuboCop configuration record within the root of the brand new Ruby on Rails application initialized with the template.
The very last thing is to scrub up the default Rails code with RuboCop after the undertaking initializes, and when all RuboCop gemstones are to be had.
Trace: after package installs.
Upload the next code:
after_bundle do run 'package exec rubocop --auto-correct' finish
On the level of writing this newsletter, with Rails 22.214.171.124, it fastened 75 of 78 offenses robotically, so I had to perform a little paintings manually.
$ package exec rubocop Analyzing 31 recordsdata .............C...............CC Offenses: config/environments/building.rb:19:6: C: Rails/FilePath: Please use Rails.root.sign up for('trail/to') as a substitute. if Rails.root.sign up for('tmp', 'caching-dev.txt').exist? ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ verify/channels/application_cable/connection_test.rb:5:7: C: Taste/ClassAndModuleChildren: Use nested module/magnificence definitions as a substitute of compact taste. magnificence ApplicationCable::ConnectionTest < ActionCable::Connection::TestCase ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ verify/test_helper.rb:7:7: C: Taste/ClassAndModuleChildren: Use nested module/magnificence definitions as a substitute of compact taste. magnificence ActiveSupport::TestCase ^^^^^^^^^^^^^^^^^^^^^^^ 31 recordsdata inspected, 3 offenses detected
Now not such a lot despite the fact that.
, despite the fact that it not too long ago stopped to mend the lacking
and would require you to manually upload it to each and every record – and it is value it.
For the ones chickens who do not like code that writes code, there is a light-weight choice that’ll level to all of the violated traces within the particular .rubocop_todo.yml record.
after_bundle do run 'package exec rubocop --auto-gen-config' finish
It does two issues:
- Launches a dry run of RuboCop, that writes .rubocop_todo.yml with violated recordsdata excluded from the following RuboCop runs
- Edits .rubocop.yml record, telling it to thoughts the exclusions
This manner you’ll be able to make certain that RuboCop’s auto-correction does now not beak the rest, through solving all of it one through one, through hand. No YOLO despite the fact that.
Now all that is left to be achieved is launching the Rails installer pointing to our new template record:
rails new project_name --template=/trail/to/native/template.rb
Sit down again and loosen up – all of it occurs robotically. Cool, huh?
When to make use of Rails Application Template
Everytime, truly, reason why the hell now not.
However for some this can be a goldmine:
Tool Properties: shall we say one undertaking per week, doing all these things – I will be able to handiest believe that there is this one go-to man, most definitely mid to senior stage, that units the stuff up, for one to three running days.
I consider my co-worker telling me a tale about any person, who labored at a Tool Area and as soon as consistent with two weeks he used to be actually putting in the similar gemstones in a subsequent new undertaking all over the place once more.
Subsequent, Freelancers: for those who occur to take on some paintings and code in Ruby on Rails, it is an effective way to hurry up the method.
Closing, Companies, or any micro products and services freaks, even smaller firms.
I would say that for those who:
- Deal with round five Ruby on Rails tasks already,
- Stay sure coding requirements for your building group,
it is time to extract the repeatedly used stuff to the template prior to beginning the following undertaking.
In the event you love to compartmentalize stuff into small Ruby on Rails items, Application Templates are methods to pass.
What is the downside with Rails Application Template?
Upkeep. You will not use it that regularly.
Rails itself, similar as numerous gemstones that you simply thankfully use, evolve.
You’ll be able to lock the gemstones variations, however it isn’t the most efficient thought – it is higher to make use of the newest strong variations to be had, for a safety causes if now not for the rest.
Simply get to the purpose and put into effect trade common sense after finishing a brief wizard within the CLI. Painlessly, easy as that.
So, how do you prefer the concept that of automating Ruby on Rails tasks initialization?
Do you be mindful the rest that might be so cool to enter the Rails Application Template?
Possibly you already use templates your self, and I have ignored one thing?
I would love your comments – please, inform me in feedback!
