  • colorls

    A Ruby gem that beautifies the terminal's ls command, with color and font-awesome icons. :tada:

    Project mention: Command Line Tools for Productive Developers | | 2022-04-09

    colorls: Colorizes the ls output with color and icons (requires gem). Includes many useful flags, such as --gs for Git status, or -t for a tree view: I use an alias to replace ls with colorls:

  • bootsnap

    Boot large Ruby/Rails apps faster

    Project mention: Acelerando o boot da sua aplicação Rails | | 2022-05-03
  • InfluxDB

    Build time-series-based applications quickly and at scale.. InfluxDB is the Time Series Data Platform where developers build real-time applications for analytics, IoT and cloud-native services in less time with less code.

  • wordmove

    Multi-stage command line deploy/mirroring and task runner for Wordpress

    Project mention: How To Migrate A WordPress Site (Step-By-Step) | | 2022-08-07

    If you are comfortable using a terminal i would recommend wordmove. Setting it up can be tricky but after that its probably the fastest way to sync websites.

  • counter_culture

    Turbo-charged counter caches for your Rails app.

    Project mention: counter_culture VS activerecord-slotted_counters - a user suggested alternative | | 2022-11-29
  • premailer-rails

    CSS styled emails without the hassle.

    Project mention: How to Send Tailwindcss-Styled Emails With Ruby on Rails 7 | | 2022-11-14

    But this won't work in Rails out of the box. Unless you create your layouts using HTML tables and use something like the premailer-rails gem to inline your CSS (I haven't tried this approach).

  • Lol DBA

    lol_dba is a small package of rake tasks that scan your application models and displays a list of columns that probably should be indexed. Also, it can generate .sql migration scripts.

  • Goldiloader

    Just the right amount of Rails eager loading

    Project mention: Proof of Concept: auto-preloading in ActiveRecord | | 2022-10-31

    There are many gems doing this. I use this one :

  • Zigi

    Close all those tabs. Zigi will handle your updates.. Zigi monitors Jira and GitHub updates, pings you when PRs need approval and lets you take fast actions - all directly from Slack! Plus it reduces cycle time by up to 75%.

  • dry-validation

    Validation library with type-safe schemas and rules

  • colorize

    Ruby string class extension. It add some methods to set color, background color and text effect on console easier using ANSI escape sequences.

    Project mention: Terminal Colors Using Ruby | | 2022-09-22

    So you want to add color to your terminal app? Since you're a programmer, the first thing you do is go straight to Google. This generally leads people to two ideas. One is the popular Colorize gem, which is an easy and super convenient way to get color functionality into your app. You just install the gem, require it into whatever file(s) you wish to use it in, and then you'll have several color utility functions added onto the String class. Other things people often run into are Stack Overflow posts like this one, which essentially peel back the curtain on how the Colorize gem works. When we want to add colors to a string, we wrap the string in an ANSI escape code that signals how your terminal emulator should style the text.

  • dip

    Development-environment CLI program providing the native-like interaction with a Dockerized application.

    Project mention: Dockerizing a Ruby on Rails Application | | 2022-05-10

    And then also add dip to get rid of these lengthy docker compose run prefixes from the every command typed in your console.

  • render_async

    render_async lets you include pages asynchronously with AJAX

    Project mention: how would i create a progress bar in rails front-end using jquery and bootstrap with ajax calls to another rails server, which returns progress statistics in api | | 2022-11-09

    If it were a more simple rails app you could use

  • BatchLoader

    :zap: Powerful tool for avoiding N+1 DB or HTTP queries

    Project mention: N+1 problem will never be an issue with N1Loader gem | | 2022-01-22

    Interesting, I've just been researching Dataloader implementations for Ruby and have between trying to decide between GraphQL::Dataloader, graphql-batch and BatchLoader. I'll give this a look as well. Can you also make API calls inside the loaders?

  • Ruby Facets

    Ruby Facets

  • rainbow

    Ruby gem for colorizing printed text on ANSI terminals (by sickill)

    Project mention: Where to put custom methods that are accesible anywhre in the application. | | 2022-08-14

    You can add methods to every object but again, usually not the best way. If you need this very often in a class / file and want to avoid a lot of repetition of calling a method on a utility class you can use Refinements to alter e.g. String for that class / file. example in Rainbow

  • Coltrane

    Project mention: Open source reverse guitar chord/key/scale finder? | | 2022-04-16
