It explains how port conflicts can come from Node running behind Yarn and recommends assigning Yarn a port so Node inherits it through the environment. ### Source excerpt Pizza courtesy of Pizza for Ukraine! Donate Now to Pizza for Ukraine As I've said, I build a lot of side projects and I really, really like the model of having: ALL MY APPS RUNNING CONCURRENTLY I may be a scattered, distracted developer trying to do too damn much but that's my damn right. And I have 64 gigs of RAM so why shouldn't I be this way. What I want is to be able to switch from app to app and make changes. This is important because some apps provide APIs which other apps rely on and having to figure out what thing is on what port, etc, is just plain distracting. Foreman and Procfile.dev is a way around this but there's a major hitch in your getalong (as my Texas wife might say). Here's a sample Procfile.dev for an app I'm building called Cartazzi which makes a developer's life easier: web: bin/rails server -p 5000 css: yarn build:css --watch js: yarn build --reload # docker: docker-compose up And here's a Profile.dev for another application called Poolwizard which helps you maintain your swimming pool: #web: bin/rails server -p $PORT web: bin/rails server -p 5700 css: yarn build:css --watch js: yarn build --reload # docker: docker-compose up worker: bundle exec sidekiq If you run Cartazzi and Poolwizard together then you're going to get crashes and here's the error: ❯ foreman start -f Procfile.dev 09:11:53 web.1 | started with pid 72877 09:11:53 css.1 | started with pid 72878 09:11:53 js.1 | started with pid 72879 09:11:53 worker.1 | started with pid 72881 09:11:53 js.1 | yarn run v1.22.5 09:11:53 css.1 | yarn run v1.22.5 09:11:53 css.1 | $ tailwindcss --postcss -i ./app/assets/stylesheets/application.tailwind.css -o ./app/assets/builds/application.css --watch 09:11:53 js.1 | $ node esbuild.config.js --reload 09:11:54 js.1 | node:events:371 09:11:54 js.1 | throw er; // Unhandled 'error' event 09:11:54 js.1 | ^ 09:11:54 js.1 | 09:11:54 js.1 | Error: listen EADDRINUSE: address already in use :::5200 09:11:54 js.1 | at Server.setupListenHandle [as _listen2] (no ## Setup a Monorepo with PNPM workspaces and speed it up with Nx!

It covers opening a server port, installing Soketi with npm or Yarn, configuring a Forge daemon, verifying the service, and updating a Laravel application to connect to Soketi through Laravel Echo. It also mentions optional drivers, SSL support, debugging, and environment-variable configuration. ### Source excerpt Soketi is a simple, fast and resilient open-source WebSockets server written in Typescript. It's fully compatible with the Pusher v7 protocol which makes it a great replacement to Pusher when using Laravel Echo. ## Rails 6 - Can't Find Application.js DevFeed: [Rails 6 - Can't Find Application.js]() Original publisher: [Read original article]() Author: Fuzzygroup Published: 2021-12-18T14:51:00Z Content type: tutorial Language: en Sources: [Scott Johnson]() Topics: [Rails](), [Yarn](), [Development]() Tags: [asset-pipeline](), [bash](), [command](), [compilation](), [foreman](), [git](), [js](), [rails](), [rake]() ### AI overview A troubleshooting note about a Rails 6 project where Webpacker cannot find application.js. It explains installing Webpacker and using bin/dev with Foreman so the JavaScript and CSS asset processes run. ### Source excerpt So I started fiddling about with a new Rails project and after finding a likely starting point, I immediately ended up with this: Webpacker can't find application.js in I'm old school Rails and I find the whole asset compilation situation, honestly, perplexing. The solution turned out to be: bundle exec rails webpacker:install after the normal: git clone foo bundle install bundle exec rake db:migrate I have no idea why the bundler install doesn't handle executing webpacker:install but cie la vie. The more things change, the more they stay the same ... Update: I kept at this and kept finding that I didn't have webpacker or some other portion of the rails stack running. I finally traced this down to things having changed. Traditionally I've always run rails as: bundle exec rails s -pXYZ And the new approach is to run: bin/dev which in turn contains: #!/usr/bin/env bash if ! command -v foreman &> /dev/null then echo "Installing foreman..." gem install foreman fi foreman start -f Procfile.dev "$@" and the Procfile.dev file contains: web: bin/rails server -p 3000 js: yarn build --watch css: yarn build:css --watch I was literally missing the yarn command so part of the overall asset pipeline just wasn't running. Old habits die hard. ## Setting Up Windows for JavaScript Development with WSL, Node.js, Yarn, VS Code, and Zsh DevFeed: [Setting Up Windows for JavaScript Development with WSL, Node.js, Yarn, VS Code, and Zsh]() Original publisher: [Read original article]() Author: Techno Tim Published: 2020-03-12T14:00:00Z Content type: tutorial Language: en Sources: [Techno Tim]() Topics: [Development](), [JavaScript](), [Windows](), [Windows Subsystem for Linux](), [Ubuntu](), [Zsh](), [npm](), [Yarn](), [Command-line interface](), [vs-code]() Tags: [coding](), [install](), [javascript](), [npm](), [tutorial](), [ubuntu](), [vs-code](), [windows](), [wsl]() ### AI overview A beginner tutorial for configuring a Windows machine for JavaScript development.

This blog post walks through the commands we used today and explains them. If you're an old hat at this, just move on but if you're starting out, I suspect this may be quite helpful. Navigate to the Right Starting Directory cd /Users/sjohnson/Sync/coding/rails/ Make Sure Rails is Ok rails --version Set the Ruby Version rvm use 2.7.0 Find a Rails New Command from my History history | grep 'rails new' Create a New Rails App rails new dev_home_page --database=mysql Change Into The Directory cd dev_home_page Run Bundle Install bundle install Start a Web Server bundle exec rails s -p3096 Open the web server in your browser with: http://localhost:3096/ Close Web Server with Ctrl+C and Edit config/database.yml mate config/database.yml You need to set the user and password on your database server in the first configuration block within the database.yml file. Create the Database Itself bundle exec rake db:create Run rake db:migrate bundle exec rake db:migrate Start Two More Terminal Panes I run iTerm and I'm a firm believer in the "The Trininty of Terminal Windows for Rails Development" so I right click in my terminal window and select Split Pane Horizontally twice giving me 3 terminal windows in one. I then go back to my first terminal window and get the current directory. Note 1: The trinity of terminal windows is Web Server, Rails Console and a Command Line for git commits / whatever else. Note 2: The same result can be done with 3 tabs in standard OSX Terminal. I just adore iTerm; it has made my life better. Note 3: Start your Rails Console in the middle pane with: bundle exec rails c Get the Current Directory and Set all Terminal Panes to this Directory pwd and then in each other terminal pane, do: cd /Users/sjohnson/Sync/coding/rails/dev_home_page This is the directory that pwd displayed or you. Install Yarn curl -o- - ## Jumpstart Rails Tutorial 01 - Bringing an Existing Codebase In DevFeed: [Jumpstart Rails Tutorial 01 - Bringing an Existing Codebase In]() Original publisher: [Read original article]() Author: Fuzzygroup Published: 2020-01-02T00:00:00Z Content type: tutorial Language: en Sources: [Scott Johnson]() Topics: [Rails](), [Tutorial](), [repo](), [Code](), [Deployment](), [Databases](), [Yarn](), [GitHub]() Tags: [code](), [database](), [deployment](), [development](), [getting-started](), [github](), [how-to](), [jumpstart](), [rails](), [repo](), [tutorial]() ### AI overview This tutorial series documents porting an existing Rails application into the Jumpstart Rails application framework. The first article covers cloning the licensed repository, installing dependencies with Yarn, updating database.yml, and adding the local codebase to GitHub. ### Source excerpt Updated: 5/5/2020 It is the second day of the New Year - welcome to 2020 - and I have still failed to launch my side project that I started midway through 2019. Sigh. I find myself fundamentally regretting this but, well, life: New Job Wife in Hospital Son and Schooling Issues Etc So my New Year's Resolution(s) is: Launch by end of Q1, 2020 Not have deployment eat my brain Launch with Something that I'm Visually Proud Of Launch with SAAS billing features from day 1 and Get paying Customers That last item, SAAS billing features, is a sticky point. I've actually implemented this myself before - I wrote all the back end code for the AppData SAAS engine which successfully processed over 3.1 million dollars in revenue over a 5 year period (BrainTree api). And I really, really, really don't want to rewrite that. Nor do I want to use a third party service and lose another percentage chunk over baseline Stripe fees. And all of this means that I need to use the Jumpstart Rails application framework. I already have a license for it anyway and the issue is that I need to port an existing, almost complete Rails app into it. All of the blog posts starting with Jumpstart Rails Tutorial nn will cover this process. While there is good documentation for Jumpstart Rails, it is reference material rather than how to material. Note: If anything I write during this series comes off as critical of Chris Oliver, the man behind Jumpstart Rails, it isn't. I am an unabashed fan of the damn fine work that Chris Oliver does. Step 1 - Getting Started with Jumpstart Rails - Clone the Repo The first step is to purchase an actual license for Jumpstart Rails. This will get you added onto the Jumpstart Rails git repo: https://gitlab.com/gorails/jumpstart-pro What you need to do is begin by cloning this repo down to your local system: git clone git@gitlab.com:gorails/jumpstart-pro.git web_change_me_now2 You notice that I changed the name of this to: web_change_me_now2 I changed it since my previous re ## Add Mocha reporter for Karma unit tests to your Angular CLI project DevFeed: [Add Mocha reporter for Karma unit tests to your Angular CLI project]() Original publisher: [Read original article]() Published: 2018-02-13T00:00:00Z Content type: tutorial Language: en Sources: [Juri Strumpflohner]() Topics: [Angular](), [Angular CLI](), [Mocha](), [test](), [npm](), [Yarn](), [Command-line interface]() Tags: [angular](), [cli](), [how-to](), [install](), [npm](), [tests](), [unit-tests](), [video]() ### AI overview This tutorial explains how to replace Karma's default progress reporter with the Karma Mocha reporter in an Angular CLI project.
