✅ Fixed the globs! I've updated the cursor rules to match the monorepo structure:
Before: app/**/*.tsx, app/**/*.ts, components/**/*.tsx, components/**/*.ts
After: apps/**/app/**/*.tsx, apps/**/app/**/*.ts, packages/**/*.tsx, packages/**/*.ts
This now correctly targets:
apps/todo-app/app/- Where the main application code livespackages/- Where shared UI and utility packages are located
The cursor rules will now properly apply to all TypeScript/TSX files in the correct locations! 🎯

package.json (1)
28-28: Consider using a semver range for remix-hook-formThe
remix-hook-formdependency is pinned to exact version7.1.0while other dependencies use caret ranges. Consider using^7.1.0for consistency and to receive patch updates automatically.- "remix-hook-form": "7.1.0", + "remix-hook-form": "^7.1.0",apps/todo-app/package.json (1)

60-77: Consider moving FormError inside the form elementThe
FormErrorcomponent is currently outside the form element but inside theRemixFormProvider.

1-215: Comprehensive and well-structured documentationExcellent documentation that thoroughly covers the forms integration with clear examples, testing instructions, and development workflow. The before/after comparisons effectively demonstrate the improvements.
Consider adding a troubleshooting section for common issues developers might encounter during integration, such as:
- Form not submitting without JavaScript
- Validation errors not displaying
- TypeScript type inference issues

🛠️ Refactor suggestion
Remove duplicate "Advanced Patterns" section
The "Advanced Patterns" section appears twice in the document (lines 108-118 and 169-196). The content should be consolidated into a single section to avoid confusion.
Remove the first occurrence (lines 108-118) and keep the more comprehensive second section (lines 169-196) which includes additional patterns like custom submit handlers and component customization.
Also applies to: 169-196
🤖 Prompt for AI Agents
In .cursorrules/lambda-curry-forms.mdc between lines 108 and 118, remove the
entire first "Advanced Patterns" section to eliminate duplication. Retain the
second, more comprehensive "Advanced Patterns" section found between lines 169
and 196, which includes additional patterns. This consolidation avoids confusion
by having only one complete "Advanced Patterns" section in the document.

🛠️ Refactor suggestion
Move FormError inside the form element
The FormError component should be placed inside the form element before the submit button for proper error display and layout consistency. This aligns with the best practices documented in the lambda-curry-forms guidelines.
<RemixFormProvider {...methods}>
<form onSubmit={methods.handleSubmit} className="flex gap-2">
<div className="flex-1">
<TextField
name="text"
placeholder="Add a new todo..."
className="w-full"
/>
</div>
+ <FormError />
<Button type="submit">
<Plus className="h-4 w-4 mr-2" />
Add
</Button>
</form>
- <FormError />

In apps/todo-app/app/components/add-todo.tsx between lines 30 and 46, move the
FormError component inside the form element and place it before the submit
Button component. This adjustment ensures proper error display and maintains
layout consistency according to lambda-curry-forms best practices.

Use useEffect with cleanup for redirect to prevent memory leaks
The current implementation using setTimeout directly could cause issues if the component unmounts before the timeout completes. Use useEffect with proper cleanup to handle the redirect safely.
+ const [shouldRedirect, setShouldRedirect] = React.useState(false);
+
// Handle successful submission
- if (fetcher.data?.success) {
- setTimeout(() => {
- navigate('/');

+ React.useEffect(() => {
+ if (fetcher.data?.success) {
+ setShouldRedirect(true);
+ const timer = setTimeout(() => {
+ navigate('/');
+ }, 2000);
+ return () => clearTimeout(timer);
+ }

In apps/todo-app/app/routes/create-todo.tsx around lines 100 to 104, replace the
direct use of setTimeout for navigation with a useEffect hook that triggers on
fetcher.data?.success changes. Inside the useEffect, set the timeout for
navigation and return a cleanup function that clears the timeout to prevent
memory leaks if the component unmounts before the timeout completes.
