Creating Components

Workflow

Copy this checklist and track progress:

Component Progress:
- [ ] Step 1: Determine placement
- [ ] Step 2: Create folder structure
- [ ] Step 3: Create component file
- [ ] Step 4: Add sub-components (if needed)
- [ ] Step 5: Validate against checklist
- [ ] Step 6: Run lint fix and re-check

Step 1: Determine placement

Infer from context if possible, otherwise ask the user. See references/placement.md for paths and conventions for each type:

• Shared (common) component
• Page-specific component
• Sub-component of existing component
• Page component

Step 2: Create folder structure

Create a kebab-case folder in the appropriate location. See references/folder-structures.md for diagrams of each scenario.

Step 3: Create component file

Create a PascalCase .tsx file inside the folder. Follow the conventions in references/REFERENCE.md.

Step 4: Add sub-components (if needed)

If the component needs sub-components, create a components/ folder inside it. Each sub-component follows the same rules. See references/placement.md for the sub-component pattern.

Step 5: Validate against checklist

Run through the validation checklist below before considering the component complete.

Step 6: Run lint fix and re-check

Run linter with auto-fix scoped only to the created or modified files. If errors remain after auto-fix, notify the user that manual fixes are required and stop — do NOT suppress errors with eslint-disable, @ts-ignore, @ts-expect-error, or any other suppression directives.

Validation checklist

After creating a component, verify every item:

Naming

• Folder name is kebab-case (e.g., card-content)
• File name is PascalCase and matches the exported component (e.g., CardContent.tsx exports CardContent)
• File is inside its own folder (not loose in a parent directory)

Exports

• Uses named export: export const ComponentName: React.FC<Props>
• No default exports
• One component per file

Props

• Props defined as type Props (not interface)
• Props ordered: required → optional → function callbacks
• React.FC<Props> used (or React.FC if no props)

Structure

• Component placed in the correct directory (common vs page-specific)
• Sub-components live in a components/ subfolder, not alongside the parent
• Implicit return used when the body is JSX-only

Files

• Optional helper files (types.ts, constants.ts, helpers.ts, index.ts) created only if needed

Linting

• Lint was run for changed component files
• Lint auto-fix was run
• No new lint errors remain in touched files
