# Deprecated Functions and Code

This document tracks functions that have been marked as deprecated and should be removed in future releases.

## Email Parsing and Processing Functions

### 1. `splitEmailHeadersAndBody`
- **Location**: `app/courrier/page.tsx`
- **Reason**: Email parsing has been centralized in `lib/mail-parser-wrapper.ts` and the API endpoint.
- **Replacement**: Use the `decodeEmail` function from `lib/mail-parser-wrapper.ts` which provides a more comprehensive parsing solution.
- **Status**: Currently marked with `@deprecated` comment, no usages found.

### 2. `getReplyBody`
- **Location**: `app/courrier/page.tsx`
- **Reason**: Should use the `ReplyContent` component directly.
- **Replacement**: Use `<ReplyContent email={email} type={type} />` directly.
- **Status**: Currently marked with `@deprecated` comment, no direct usages found.

### 3. `generateEmailPreview`
- **Location**: `app/courrier/page.tsx`
- **Reason**: Should use the `EmailPreview` component directly.
- **Replacement**: Use `<EmailPreview email={email} />` directly.
- **Status**: Currently marked with `@deprecated` comment, no usages found.

### 4. `cleanHtml` (in server/email-parser.ts)
- **Location**: `lib/server/email-parser.ts`
- **Reason**: This functionality has been centralized in `lib/mail-parser-wrapper.ts`.
- **Replacement**: Use `cleanHtml` from `lib/mail-parser-wrapper.ts`.
- **Status**: Currently marked with `@deprecated` comment, used in `parseEmail` function.

### 5. `processHtml` (in parse-email/route.ts)
- **Location**: `app/api/parse-email/route.ts`
- **Reason**: HTML processing has been centralized in `lib/mail-parser-wrapper.ts`.
- **Replacement**: Use `cleanHtml` from `lib/mail-parser-wrapper.ts`.
- **Status**: Currently marked with `@deprecated` comment, still used in the API route.

## Deprecated API Routes

### 1. `app/api/mail/[id]/route.ts`

## Migration Plan

### Phase 1: Deprecation (Current)
- Mark all deprecated functions with `@deprecated` comments
- Add console warnings to deprecated functions
- Document alternatives

### Phase 2: Removal (Future)
- Remove deprecated functions after ensuring no code uses them
- Ensure proper migration path for any code that might have been using these functions
- Update documentation to remove references to deprecated code
