Technical Details

Form Migration Strategy

Instead of using another form builder package, we opted for standard Laravel Blade forms
with Tailwind styling because:

• No additional dependencies required
• Full control over markup and styling
• Better long-term maintainability
• Follows Laravel best practices
• Lighter weight solution

Error Resolution

• Fixed "Class 'Galahad\Aire\Support\AireServiceProvider' not found" error by:
  • Clearing Laravel configuration cache
  • Regenerating Composer autoload files
  • Removing cached bootstrap files

Testing Performed

• ✅ Verified responsive behavior at all breakpoints
• ✅ Tested mobile menu functionality
• ✅ Confirmed Slack buttons display correctly on all screen sizes
• ✅ Validated Alpine.js functionality on calendar-feed page
• ✅ Checked all migrated pages match original styling
• ✅ Verified build process works without errors
• ✅ Confirmed no Bootstrap classes remain in active use
• ✅ Tested both contact and Slack sign-up forms for proper functionality
• ✅ Verified form validation and error display
• ✅ Confirmed HCaptcha integration still works

Breaking Changes

None - all changes maintain backward compatibility and visual parity.

Migration Checklist

• All pages migrated from Bootstrap to Tailwind CSS
• All Bootstrap dependencies removed
• Build system updated to use plain CSS instead of SASS
• Alpine.js properly integrated
• All forms converted from aire to standard Laravel forms
• All backup files removed
• Application starts without errors
• All forms functional with proper validation

Notes

• PHP version requirement remains 8.1-8.3 (documented in PHP_VERSION_REQUIREMENT.md)
• The codebase is now fully on Tailwind CSS with no Bootstrap or aire dependencies
• Forms use standard Laravel/Blade patterns for better long-term maintainability

Update 8/8/25:

1. Aire Forms Restoration

• Installed and configured glhd/aire package with Tailwind
  CSS classes
• Restored forms in /contact and /join-slack pages with
  cleaner, more maintainable syntax
• Published Aire vendor views for customization
• Configured validation states in config/aire.php

2. Validation Strategy

• Disabled HTML5 validation with novalidate() attribute to
  allow custom validation
• Implemented client-side validation for simple fields
  (name, email, checkbox)
• Server-side validation handles complex fields (textareas)
  for reliability
• Added real-time submit button state management based on
  field validity

This is my first run-through of questions.

[beetz12]

I just resolved the merge conflicts

[allella]

@beetz12 Overall, this looks good with no major issues that I see.

I did a first pass through with the live database imported on localhost, and here are minor styling items of note.

Underlining of Linked Buttons

type="button"

These tags with type="button" show an underlined styling of the text, which differs from the current site.

On the /hg-night page, the "Submit a Talk" and "Join our Meetup Group" buttons.

The "Recap" and "Videos"

Other Buttons Impacted

This underlining also happens on the "Subscribe" button on the /events and /calendar pages, though it doesn't use the same type="button".

HG Nights Page Call to Action Box Width

On the /hg-nights page, the two call to action boxes at the top aren't as wide as the event summary boxes below, which creates an odd appearance in the web browser.

Homepage Timeline

On the homepage, the timeline of "Upcoming Events" shows a green calendar icon which does not show in the Bootstrap theme, but that's because the code, oddly, uses a "display:none" to hide it. I don't think we need the green icon there, so unless it's going to mess up some other part of the site, we could remove the following from the view / Blade file.

<div class="timeline-badge bg-success">
    <i class="fa fa-calendar"></i>
</div>

Homepage Timeline Vertical Line Positioning

On the same homepage timeline, there's a stylized vertical line that's showing to the left of the timeline on the Bootstrap site. This appears to be a CSS styling using .timeline:before

On the Tailwind version the vertical line is showing to the right side and is overlapping other elements of the timeline.

Footer Icon Alignment

The "Links" and "Other Links" in the footer had left alignment in Bootstrap and appear to have a center alignment in the new Tailwind version. The left alignment feels more appropriate in my opinion.

Missing Jumbotron Image on HG Labs Page

The div id="#jumbotron-image" in Bootstrap had a CSS background image. This is missing in Tailwind.

The CSS for that image targeted a /img/labs.png as seen in resources/sass/labs.scss

    min-height: 30em;
    background-color: white;
    background: url(img/labs.png) no-repeat top left;
    background-position-x: 0;
    position: relative;
}

Bulleted List Margin on About Page

The Bootstrap site had a 2em margin on the <li> elements. The Tailwind has no margin. It seems a 1em margin would be a good middle-ground.

Contribute Page Call to Action Alignment

The top section was previously left aligned in the Bootstrap site and is center aligned in Tailwind. Since the other pages primarily use left alignment in this section, maintaining left aligning on /contribute seems appropriate.

[irby]

I will confirm many of the findings from @allella. In particular, seeing several styling inconsistencies. The largest one being the calendar alignment issue on the homepage that @allella posted above.

I'm seeing the About Us page has some changes in the Tailwind update as well, with links previously with no underline and green highlight are now showing with gray text and an underline, with some changes to the size of the headers.

I'm also seeing the active page is not being highlighted in the Tailwind version.

A positive improvement I see is on the /hg-nights page, where the new Tailwind version does look better than the Bootstrap version. I really like this change.

One last thing I have is that I needed to use yarn add alpinejs to upgrade alpinejs to ^3.15.2 in my package.json in order for yarn build to succeed. Otherwise, when I tried to access http://localhost:80 I got an issue with my build.

But, I will agree with Jim that this is excellent work and overall this looks really good, there's some regressions with the stylings I would like to see resolved but I appreciate the hard work put into this PR!

[allella]

@irby we had to run yarn install on dev, and in a stage test, so that may be a deployment gotcha note if the deploy process doesn't do the trick.

[beetz12]

@allella thanks for the detailed review. I'll get these resolved this week!

[beetz12]

@allella I just updated the site with the changes. Please review and let me know if you need anything else.

[allella]

@beetz12 Things look good on the browser side related to the suggestions I shared.

Matt's suggestion to highlight the main header .nav-link active navigation in #FFF color is the main thing I see left that isn't minor text changes that looks to be worth the time.

I've asked Zach Robichaud to give the PR a technical review.

As a side note, I also like the wider "hero" image on the new /hg-nights page.

This could be another PR, but having the same header on the /labs page would be nice for consistency, as the two pages have always been inconsistent.

I can find a higher resolution photo of that existing image, or something comparable, if we want to add that sort of change into this PR.

Thanks

[beetz12]

@allella thanks for the update! Sorry for the late response, it's been a busy week.

No problem, I'll add highlighting for the main header .nav-link active navigation in #FFF.

I'm not sure if I understand the "wider "hero" image on the new /hg-nights page.", In my PR, I made the /labs page and home page look the same as our current pages. I do think it's a great idea to make them look consistent, and I'm happy to help.

But I would prefer if we create a new PR for this feature - it would be great to look back on this PR in the future and know that all changes are related to the Tailwind migration. Thoughts?

[allella]

@beetz12 we can leave the wider image change to a future issue.

Though, @zach2825 comments on the other, now closed, PR about remaining Bootstrap classes may still apply.

#590 (review)

I ran the suggested grep command on this PR and it did come up with a number of matches.

[beetz12]

@allella @zach2825 I just remove the remaining references to bootstrap styles and added "highlight the main header .nav-link active navigation in #FFF color". I also made some responsive layout fixes to the header and the /labs page. Please review, and let me know if you want to make any other changes.

[allella]

Thanks @beetz12

It still looks good on localhost with production data testing.

I think the main thing now is getting our new stage and production server setup on Railway.

I'll ping Bogdan to see if we're close to getting that finalized, or if we need to go find a middle-ground to keep things moving.

[beetz12]

That's great @allella. I'll defer to you and Bogdan on the server setup. Just FYI, I'm also experienced with railway and I could also help with setup if needed. I'll be at to Openworks most days now so we could meet there to knock it out.

[zach2825]

👍🏻 looks great 💯

[beetz12]

@zach2825 great, thanks for the review!
