Some time ago, we worked on a project with ClojureScript. 9 | 10 | There are many benefits to this language, but today I want to focus on the feature called `hot-reload`. The idea is super simple, yet powerful: the web page is reloaded on file save. This small but useful feature saved me a few keystrokes and allowed me to stay focused in the editor while seeing immediate changes in the browser. 11 | 12 | As you can see above, without moving out from my editor, the page reloads and I can see the changes immediately! Now… let's replicate that behavior in Ruby on Rails 7. 13 | 14 | --- 15 | 16 | ### Let's quickly build a new Ruby on Rails app 17 | 18 | ```sh 19 | gem install rails 20 | rails new test-app --css tailwind 21 | cd test-app 22 | ./bin/dev 23 | ``` 24 | 25 | --- 26 | 27 | ### Then we need to do a few configuration changes: 28 | 29 | 1. **Edit `Gemfile` and add [`hotwire-livereload`](https://github.com/kirillplatonov/hotwire-livereload) gem:** 30 | 31 | ```ruby 32 | group :development do 33 | gem "hotwire-livereload" 34 | end 35 | ``` 36 | 37 | 2. **Install with bundler** 38 | 39 | ```sh 40 | bundle install 41 | ``` 42 | 43 | 3. **Run installation** 44 | 45 | ```sh 46 | rails livereload:install 47 | ``` 48 | 49 | 4. **Install Redis (macOS with Homebrew)** 50 | 51 | ```sh 52 | brew install redis 53 | ``` 54 | 55 | 5. **Run Redis** 56 | 57 | ```sh 58 | brew services restart redis 59 | ``` 60 | 61 | 6. **Run Rails** 62 | 63 | ```sh 64 | ./bin/dev 65 | ``` 66 | 67 | Edit the file and see the changes! 68 | 69 | No more switching windows, hitting F5! That's a live and time saver. 70 | 71 | --- 72 | 73 | Have fun and keep coding, 74 | 75 | [Grzegorz](http://www.grzegorz-smajdor.com), founder of [deliverists.io](http://www.deliverists.io) 76 | -------------------------------------------------------------------------------- /src/_includes/layouts/blog_index.njk: -------------------------------------------------------------------------------- 1 | {% extends "layouts/base.njk" %} 2 | {% block content %} 3 |

Fixing FormData issues." 5 | layout: post.njk 6 | --- 7 | 8 | Ruby on Rails is a fantastic framework. It’s easy to build your startup with, MVP product, and just enjoy ruby. However, it changes often, and it’s challenging to keep up with best practices. 9 | 10 | Currently, we have [turbo](https://github.com/hotwired/turbo-rails) built in, but I’m not fully up to date (yet!). 11 | 12 | Recently, I needed to make a simple AJAX request to check if a user exists. Turbo probably solves this, but I used the old approach — an HTML modal + [stimulus controller](https://github.com/hotwired/stimulus-rails) + [axios](https://axios-http.com/docs/intro): 13 | 14 | ### HTML modal 15 | ```html 16 |
17 | 18 |
19 | 20 |
21 |
22 | ``` 23 | 24 | ### Stimulus controller (check_user_email_controller.js) 25 | ```js 26 | import { Controller } from "@hotwired/stimulus" 27 | import axios from 'axios' 28 | 29 | export default class extends Controller { 30 | static targets = ['email', 'submit'] 31 | connect() { 32 | this.submitTarget.addEventListener('click', (e) => { 33 | e.preventDefault(); 34 | if (this.emailTarget.value.length === 0) { 35 | alert('Please provide an email.') 36 | } else { 37 | axios.get('api/users_by_emails', { 38 | params: { 39 | email: this.emailTarget.value 40 | }, headers: {'ACCEPT': 'application/json'} 41 | }).then(function (response) { 42 | // handle success 43 | }).catch(function (error) { 44 | // handle error 45 | }); 46 | } 47 | }); 48 | } 49 | } 50 | ``` 51 | 52 | I used `axios` for the AJAX GET request. 53 | 54 | To import axios (with importmaps): 55 | ```sh 56 | ./bin/importmap pin axios 57 | ``` 58 | 59 | And that’s it — or so I thought! 60 | 61 | ### Issue 62 | After installing the newest version (`axios@1.1.3`), AJAX stopped working and the console said: 63 | 64 | ![](https://miro.medium.com/v2/resize:fit:700/1*AEuzXh_Oy-p9gFByfQPf3w.png) 65 | 66 | ``` 67 | Failed to register controller: check-user-email (controllers/check_user_email_controller) TypeError: Cannot read properties of undefined (reading 'FormData') 68 | at index.js:162:32 69 | ``` 70 | 71 | Not sure why, but even StackOverflow couldn’t help. 72 | 73 | ### Fix 74 | You have to pin axios to version **0.27.2**: 75 | 76 | ```sh 77 | ./bin/importmap pin axios@0.27.2 78 | ``` 79 | 80 | Versions after 0.27.2 have the `FormData` issue. 81 | 82 | Not sure why newer versions break, or why Turbo could make this simpler (teach me in comments!). 83 | 84 | Happy coding! 85 | 86 | — Grzegorz 87 | -------------------------------------------------------------------------------- /src/blog/2022-hamburg-marathon-rookie-run.md: -------------------------------------------------------------------------------- 1 | --- 2 | title: "2022 — Hamburg Marathon Rookie Run" 3 | date: 2023-01-14 4 | description: "My first ever marathon in Hamburg, 2022.

9 | Marathon 10 |

11 | 12 |
Wow, we have already 2023, I finally decided to write about my first ever marathon run, which happened on 24th of April 2022. I will do my best to describe how and why I decided to run it, and what was happening with me, physically and mentally, during those 5 hours.
13 | 14 |

Btw, I’m signed up for next run — join me!

15 | 16 | ## Introduction 17 | I'm in my 40s, good health, software engineer, usually sitting at work—active for fun (running, walking, biking). Ran 10km sometimes, never did marathon prep, never followed a plan or diet. 18 | 19 | ## 1 week before the marathon 20 | April 17th, Hamburg. Saw a marathon poster—decided to run. Half marathon was booked, so I signed up for full. 21 | 22 | ## Preparation to run 23 | I rested a week before (sore calf). No other prep, just nerves! 24 | 25 | ## Marathon day 26 | Started in the last “K” block (estimate: 6h). Did quick math: “I’ll try for 5h!” 27 | 28 | **My kit:** 1 protein bar, phone, 2 Hot Wheel cars from my kids. 29 | 30 |

31 | Ready for the start 32 |

33 | 34 | ## Start + 5—10—15km 35 | Lots of cheering, crowded! I overtook people, picked somebody to follow, focused/locked in. Grabbed a banana and water for the first time while running. 36 | 37 | ## 17km — Snafu 38 | Got hungry—my pocket snack was missing (still in my backpack). Mini panic and “mental dip”. Spotted my pace-runner, snapped out of it. 39 | 40 | ## 20–25km — Family, then letdown 41 | Missed seeing my kids on the bridge. Second dip. Call with my wife: “see you at the finish line!” 42 | 43 | ## 28km — Struggling 44 | Hit the wall. Stopped running, walked. Leg pain. Grit. 45 | 46 |

47 | Not fun anymore! 48 |
Not fun anymore 49 |

50 | 51 | Still going, trying not to quit. 52 | 53 |

54 | I’m done! I will just walk. 55 |
I’m done! Walking mode. 56 |

57 | 58 | ## 30–40km — Pain and Push 59 | Grabbed bananas, gels, water at food stands. Tried short runs again. Sometimes pain was worse walking than running. Just moved forward, meter by meter. 60 | 61 |

62 | Head down. 1 meter more, just 1 meter more. 63 |
Head down. 1 meter more, just 1 meter more. 64 |

65 | 66 | ## The finish (42,195m) 67 | Saw the grandstand, finish line, finally waved at my family—hi-5s and tears. Crossed the line: 4h:53m! 68 | 69 |

70 | Finish line! 71 |

72 | 73 | ## Reflections 74 | Finishing was wild—never dreamed I could do it. “Average person, not athlete.” If you care, commit, and keep going, you’ll surprise yourself. 75 | 76 | — [Grzegorz](http://www.grzegorz-smajdor.com) 77 | -------------------------------------------------------------------------------- /src/blog/rails-7-with-bootstrap-css.md: -------------------------------------------------------------------------------- 1 | --- 2 | title: "Rails 7 with Bootstrap CSS" 3 | date: 2022-01-05 4 | layout: post.njk 5 | description: "Step-by-step guide to setting up Rails 7 with Bootstrap CSS and JS, and adding custom styles. Originally published on Medium." 6 | --- 7 | 8 |

9 | Rails 7 with Bootstrap CSS 10 |

11 | 12 | Recently the Rails 7 went out and it includes a lot of changes and new features. What I want to focus on is generating a new Rails 7 app with Bootstrap CSS and Bootstrap JS. 13 | 14 | If you don’t want to read the article you can watch it here. 15 | 16 | **Disclaimer:** The commands with a `:` prefix are run from inside Vim. To understand how I use Vim with Rails, check my Ruby on Rails with Vim article. 17 | 18 | ## Create new app with Bootstrap 19 | 20 | Create a new Rails app using: 21 | 22 | ``` 23 | $ rails new app-with-bootstrap --css bootstrap 24 | ``` 25 | 26 | This will generate a new Rails app and download Bootstrap CSS and JS for you. 27 | 28 | ## Run app 29 | 30 | In Rails 7, the new way of running the server is: 31 | 32 | ``` 33 | $ ./bin/dev 34 | ``` 35 | 36 | This spins up a few processes, including the server and a watcher for CSS and JS files. 37 | 38 | ## Prepare a URL path 39 | 40 | The goal is to test Bootstrap CSS and JS on http://localhost:3000/home. To do this, edit `routes.rb` and configure it: 41 | 42 | ``` 43 | :Einitializer 44 | ``` 45 | 46 | Add: 47 | 48 | ``` 49 | root 'home#index' 50 | ``` 51 | 52 | After reloading, you’ll get an exception because `home_controller` isn’t defined yet. Let’s fix that. 53 | 54 | ## Generate controller home 55 | 56 | Generate the controller: 57 | 58 | ``` 59 | :Generate controller home 60 | ``` 61 | 62 | After refreshing, you’ll see an exception that the `index` action is missing. Add: 63 | 64 | ```ruby 65 | def index 66 | end 67 | ``` 68 | 69 | to `home_controller.rb`. 70 | 71 | Now, after refreshing, you’ll be missing the `index.html.erb` template. Create it: 72 | 73 | ``` 74 | :Eview home/index.html.erb 75 | ``` 76 | 77 | Add some text to it. When you refresh, you should see your template rendered. 78 | 79 | ## Verifying Bootstrap CSS and JS 80 | 81 | To verify Bootstrap is working, copy the modal HTML code from the Bootstrap page and paste it into your `home/index.html.erb` file. Refresh the page and click the "Launch demo modal" button—you should see the modal. 82 | 83 | ## Add custom styles 84 | 85 | To add custom styles, put your CSS in: 86 | 87 | ``` 88 | app/assets/stylesheets/custom.css 89 | ``` 90 | 91 | Then add the asset name to the Rails pipeline by editing `app/assets/config/manifest.js`: 92 | 93 | ```js 94 | //= custom.css 95 | ``` 96 | 97 | Finally, apply the styles in your application layout by editing `application.html.erb` and adding: 98 | 99 | ```erb 100 | <%= stylesheet_link_tag "custom", "data-turbo-track": "reload" %> 101 | ``` 102 | 103 | After refreshing, your modal should look different with your custom styles. 104 | 105 | --- 106 | 107 | This small tutorial guided you step by step on how to have a fully fledged Rails 7 app with Bootstrap CSS, Bootstrap JS, and your own custom styles. 108 | 109 | Watch the video version here. 110 | 111 | Have fun, 112 | 113 | Grzegorz 114 | -------------------------------------------------------------------------------- /profile.txt: -------------------------------------------------------------------------------- 1 | Contact 2 | grzegorz.smajdor@gmail.com 3 | www.linkedin.com/in/ 4 | grzegorzsmajdor (LinkedIn) 5 | grzegorz-smajdor.com (Personal) 6 | github.com/gs/watircuke (Other) 7 | github.com/maltize/sublime-text-2- 8 | ruby-tests (Other) 9 | Top Skills 10 | Training 11 | Engineering 12 | Mentoring 13 | Languages 14 | Polish (Native or Bilingual) 15 | English (Full Professional) 16 | German (Limited Working) 17 | Certifications 18 | Co-Active Coaching Fundamentals 19 | Grzegorz Smajdor 20 | Co-Founder / Mentor / Software Developer 21 | Greater Hamburg Area 22 | Summary 23 | Love to build great products and deliver value to the market. 24 | Experience 25 | Yelp 26 | Software Engineer 27 | November 2012 -

I have to admit that after this time, I feel much lighter (not just because I’ve lost ~5kg) but because my brain is sharper, and my taste and smell got more sensitive. I was journaling during this time and decided to share my experience. 9 | 10 | --- 11 | 12 | ## Day 1 13 | 14 | Starting strong, from morning, no food, just water… after a few hours I was hit by a big headache, even a migraine because of lack of caffeine. It was hard to focus on any mental activities so I had to do something physical and keep myself busy. I decided to do some cleaning and re-arrangement at home. 15 | Then cooking time came, I was cooking for family… the worst moment was that I couldn’t check how it tasted! I really, badly wanted to taste it… but NO! Luckily, the food was eatable — but not by me… :) 16 | When evening came, I got hungry… really hungry… everything was tempting, smelled nicely. However, the good thing was that the headache was gone! 17 | 18 | During 1st day, I think I drank 5–6 glasses of water 19 | Weight: 60.50 20 | 21 | --- 22 | 23 | ## Day 2 24 | 25 | I woke up as usual, ~5:30, there was a headache but much lighter than yesterday. I felt quite OK, but a little cold. Had to warm up some water and drink it to get warmer. 26 | All the food around me was tempting. Usually every 2nd day I run to the bakery in early morning for fresh bread and buns and prepare breakfast for kids to school. And… they smelled so nicely and tempting, but NO means NO! I drank a glass of hot water, it helped a lot. Afternoon, I was starving and would eat everything around. Evening cleaning after meals was also a pain — I would eat all the leftovers! 27 | I felt hungry during the whole day, although pretty stable. Headache was gone! Which was a great relief, however I was sweating a little bit. 28 | 29 | During 2nd day, I drank 5–6 glasses of warm water 30 | Weight: … did not check 31 | 32 | --- 33 | 34 | ## Day 3 35 | 36 | I got up this morning at 5:30am, quite refreshed. Did some meditation and around 6:15am went for a small morning run, small, as I got tired quickly and just decided to walk, as I got quickly out of breath. 37 | No headache. The whole day was pretty steady — no energy spikes. Quite calm. I have joint (knee) pain but it is not very bothersome. I felt a little revolution in my gut… but nothing serious. The energy level was steady, I did not feel any ups and downs. 38 | 39 | During 3rd day, I drank 5–6 glasses of warm water 40 | Weight: 58.7 41 | 42 | --- 43 | 44 | ## Day 4 45 | 46 | Morning quite OK, woke up ~6am this time, did some meditation. And went for a cup of warm water. Overall energy level is OK and I feel stable, but my head is playing tricks on me (I was dreaming about burger!). Basically, today I would eat everything that I can see! I have little doubts… ‘why am I doing this’, ‘what for’… as there is so much delicious food around me! I could just simply enjoy it. The most surprising thing was that I did not feel attracted to coffee. That was a BIG win! 47 | 48 | During 4th day, I drank 5–6 glasses of warm water 49 | Weight: 58.6 50 | 51 | --- 52 | 53 | ## Day 5 54 | 55 | Morning same as yesterday, same routine and interesting, feeling a lot of energy in the morning. Don’t feel like I need sleep anymore. Super light. During the day, all stable nothing special. The energy level low for physical activities but brain is working sharply. I did not feel hungry and had no urge to eat. 56 | 57 | Water: 5–6 glasses of warm water 58 | Weight: 58.40 59 | 60 | --- 61 | 62 | ## Day 6 63 | 64 | Well, 5:30am today, waking up seemed pretty easy and I got up fresh and recharged. I’m surprised how easy the wake up is. Today I feel a little cold and get chills over my skin. My hands have become quite dry and still the physical activities are quickly exhausting, but my mind is clear and I am getting a lot of tasks done, the focus and concentration are improving. 65 | 66 | Water: 5–6 glasses of warm water 67 | Weight: 56.40 68 | 69 | I’ve lost 2kg within 1 day! Could not believe that. 70 | 71 | --- 72 | 73 | ## Day 7 74 | 75 | Morning, easy at 5:40. Feeling stable and well. Body is functioning but I need to avoid activities. I get tired quickly. I’m not hungry at all, I just know that I will drink water and that will be enough for me. 76 | 77 | Water: 5–6 glasses of warm water 78 | Weight: … did not check 79 | 80 | --- 81 | 82 | ## Last day, the 8th day 83 | 84 | Great morning, 5:30 and I feel very good and full of energy. Basically daily habit, water, the same energy, no drops, no headache, no need for caffeine. All good. 85 | 86 | I know, that’s it, I’m done with fasting today and I’m going to eat. So my taste buds are starting to salivate — interesting, as I did not have this for 4 days. 87 | At noon, I decided to start my meal. This is shake made from boiled broccoli with carrots. Wow, delicious! Just one cup, not too much as my stomach had no food for 7 days. During the day drinking more glasses of warm water and the dinner same as lunch. 88 | 89 | Water: 5–6 glasses of warm water 90 | Weight: 54.80 91 | 92 | --- 93 | 94 | ## Conclusions 95 | 96 | In conclusion, I’m surprised that I was able to survive without food such a long time drinking just water. Usually I get hungry a lot and have to eat. But… this was different, firstly when I got hungry I drank water, but later in fasting I was just drinking not because I was hungry, but just I did not want to be dehydrated. You have to be careful not to starve yourself. 97 | 98 | I usually drank 2–3 coffees per day as I thought I can’t live without it, but during that time I proved myself that it’s not needed and my body is more stable without it. But still… will I be back to coffee…? ;) 99 | 100 | What is more, I’ve lost over 5 kg in a week. Mind got more clear and much easier to force myself to act, plan and execute. Got more focused. 101 | 102 | However, you have to be careful with physical activities because I quickly became breathless and could not exercise. So I gave up my morning run and cold showers. 103 | 104 | Now I will slowly get back to normal meals. For a few more days I will limit myself to cooked vegetables as soup. But I will also add avocado to them. For breakfast I plan to drink a low sodium broth (with turmeric, ginger and cinnamon) for 2–3 days. 105 | 106 | If you have any questions feel free to contact me! I wish you good luck! 107 | 108 | --- 109 | 110 | ## Disclosure 111 | 112 | Be aware, I did this fasting without any medical consultation, I did not prepare for it. I just thought about it and started the next day. Please check your health condition with your doctor before doing that. 113 | 114 | Wish you all the health, 115 | 116 | Grzegorz 117 | -------------------------------------------------------------------------------- /src/index.html: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 13 | 14 | 15 | 16 | 17 | 18 | Grzegorz Smajdor - Founder, CTO, Software Developer, Mentor, Consultant 19 | 20 | 21 | 28 | 29 | 30 |
