- Removes `rootDirs` so all imports will be relative in the frontend
- Updates (and unifies) imports to be `../types/...` etc instead of
relying on "types" being in the rootDir for the frontend.
- Fixes one type that was being picked up from `lib` in the frontend.
- Adds a precommit hook to check in future
Paves the way to writing _unit_ tests for the frontend for the subset of
the frontend code we can import from `node` (which might be a lot of
it!)
## Summary
Fixes `TypeError: Cannot read properties of undefined (reading
'content')` in `findConfig()` when URL parsing fails and no saved state
is available.
## Root Cause
This error occurs when:
1. `url.deserialiseState()` throws an exception due to
malformed/corrupted URLs
2. No saved state exists in localStorage
(`sessionThenLocalStorage.get('gl', null)` returns `null`)
3. Code attempts to access `config.content` when `config` is still
`undefined`
The error happens legitimately from truncated URLs, corrupted bookmarks,
or URL shortener issues.
## Changes
- Changed `if (!config.content || config.content.length === 0)` to use
optional chaining: `if (!config?.content || config.content?.length ===
0)`
- This gracefully handles the null/undefined case and falls back to
default config as intended
## Impact
- Maintains existing user experience (fallback to default config when
URL parsing fails)
- Prevents crash with 1430+ reported occurrences
- No behavioral changes for valid URLs

Fixes issues with missing components (e.g. from beta, 'explain')
The issue was that the exceptions are thrown in `initLayout`, not in the
constructor.

This PR completes the migration from Bootstrap 4 to Bootstrap 5.3.5
following the plan outlined in
[docs/Bootstrap5Migration.md](https://github.com/compiler-explorer/compiler-explorer/blob/mg/bootstrap5/docs/Bootstrap5Migration.md).
## Migration Process
We followed a phased approach as documented in the migration plan:
1. **Phase 1: Dependency Updates and Basic Setup**
- Updated Bootstrap from 4.6.2 to 5.3.5
- Added @popperjs/core dependency (replacing Popper.js)
- Updated Tom Select theme from bootstrap4 to bootstrap5
2. **Phase 2: Global CSS Class Migration**
- Updated directional utility classes (ml/mr → ms/me)
- Updated floating utility classes (float-left/right → float-start/end)
- Updated text alignment classes (text-left/right → text-start/end)
3. **Phase 3: HTML Attribute Updates**
- Updated data attributes to use Bootstrap 5 prefixes (data-bs-toggle,
data-bs-target, etc.)
- Fixed tab navigation issues
4. **Phase 4: JavaScript API Compatibility Layer**
- Created bootstrap-utils.ts compatibility layer
- Updated component initialization for modals, dropdowns, popovers, etc.
5. **Phase 5: Component Migration**
- Updated and tested specific components (modals, dropdowns, toasts,
etc.)
- Fixed styling issues in cards and button groups
6. **Phase 6: Form System Updates**
- Updated form control classes to Bootstrap 5 standards
- Updated checkbox/radio markup patterns
- Simplified input groups
7. **Phase 7: Navbar Structure Updates**
- Updated navbar structure with container-fluid
- Fixed responsive behavior
8. **Phase 8: SCSS Variables and Theming**
- Added custom CSS fixes for navbar alignment
- Verified theme compatibility
9. **Phase 9: Accessibility Improvements**
- Updated sr-only to visually-hidden
- Added proper ARIA attributes
- Enhanced screen reader support
## Key Changes
- No more jQuery dependency in Bootstrap 5
- New prefix for data attributes (data-bs-*)
- Improved accessibility with ARIA attributes
- Updated positioning classes (start/end instead of left/right)
- Simplified input group structure
## Test Plan
1. **Navigation Testing**
- Verify all dropdown menus open and close properly
- Test mobile menu responsiveness
- Check tab navigation in settings dialog
2. **Component Testing**
- Verify all modals open and close correctly (settings, share,
load/save)
- Test tooltips and popovers
- Check form controls in different dialogs
3. **Layout Testing**
- Test responsiveness on different screen sizes
- Verify proper alignment of elements
- Check dark mode compatibility
4. **Specific Features to Test**
- Compiler selection and options
- Share dialog functionality
- Settings dialog
- Tree view (IDE mode)
- Font selection dropdown
5. **Browser Testing**
- Test in Chrome, Firefox, Safari
- Test in mobile browsers
## Note on Further Improvements
After this migration is stable, we could consider Phase 12: removing
jQuery dependency entirely, as Bootstrap 5 no longer requires it. This
would be a separate effort.

When settings are set to emit-short-link upon ctrl+S, managing the logic
in `Editor` is problematic since the editor may lose focus and not
receive the event.
Also logically this is a cross-site event, and doesn't belong in any
particular editor (there can be multiple).

IT
Thanks for taking the time to improve CE. We really appreciate it.
Before opening the PR, please make sure that the tests & linter pass
their checks,
by running `make check`.
In the best case scenario, you are also adding tests to back up your
changes,
but don't sweat it if you don't. We can discuss them at a later date.

Fix#6464, following the discord discussion.
2 protections are added here:
(1) Make the first code editor non-closable, to avoid an empty layout,
(2) If a loaded config has empty layout - fallback to the default
config.
In conversation with @mknejp he pointed out that it can be frustating
when having a browser loaded up with many tabs of CE links, then
reloading the browser (e.g. a reboot, or open/closing the tabs), that
upon reload all the tabs will have the same, shared state (corresponding
to whichever saved to local storage last).
This change:
- stores state in _both_ session and local storage
- removes from both on UI reset
- loads first from session storage and then falls back to local storage
The net result is:
- tabs reopened with "ctrl-shift T" will regain their prior state, as do
any other tabs for which the browser thinks are part of the same session
(like on a "reopen tabs" plugins etc)
- newly-opened tabs still have the prior behaviour of using whatever the
most recently opened tab had as its starting state

This PR refactors some common utilities out of lib/ and into shared/ and
eliminates some use of underscore.js, as well as general type
improvements done along the way.
Makes the Compiler Explorer app, and all the tooling ESM compatible.
Things that have been done:
1. The package.json has `type: module` now
2. All relative imports have a .js ending
3. All directory imports are now directory/index.js to comply with ESM
standards
4. Dependency node-graceful is now imported into tree, because the
package is broken under esm
5. Dependency p-queue has been bumped to 7.x with ESM support
6. Dependency profanities has been bumped to 3.x with ESM support
7. Webpack config is now both ESM and CommonJS compatible
8. Non-ESM compatible imports have been rewritten
9. ESLint configuration has been tweaked to not fail on .js imports
10. Mocha is now hacked together and ran with ts-node-esm
11. Webpack is now hacked together and ran with ts-node-esm
12. Webpack config is now ESM compatible, so that it can be used in the
dev server
13. Cypress code still runs commonjs, and has been excluded from the
tsconfig
14. All sinon mock tests have been commented out, because sinon module
mocks do not work with ESModules (because ESModules are immutable)
A lot of tests are now giving warnings/errors to stdout, yet still pass.
Docenizer codegenerator scripts have been updated, but I did not re-run
them, and instead just changed their code.
