Email to Are.na Attachment Processor

This project automatically processes email attachments and saves them as blocks to an Are.na channel.

1. Email Trigger (email-to-arena.ts): Receives emails and processes attachments
2. Blob Server (blob-server.ts): Serves stored attachments as public URLs
3. Are.na Integration: Creates blocks in your specified channel with attachment URLs

You need to set these environment variables in your Val Town settings:

• ARENA_API_KEY: Your Are.na API key (get from https://dev.are.na/oauth/applications)
• ARENA_CHANNEL_SLUG: The slug of the Are.na channel where blocks should be added
• VAL_TOWN_USERNAME: Your Val Town username (used for generating URLs)

1. Go to https://dev.are.na/oauth/applications
2. Create a new application
3. Copy the access token and set it as ARENA_API_KEY

1. Create or choose an Are.na channel
2. Get the channel slug from the URL (e.g., for https://are.na/username/my-channel, the slug is my-channel)
3. Set this as ARENA_CHANNEL_SLUG

1. Send an email with attachments to your Val Town email address
2. The system will:
   • Store each attachment in blob storage
   • Create a public URL for each attachment
   • Add a block to your Are.na channel with the attachment URL and metadata

• Supports any file type as attachment
• Preserves original filename and content type
• Adds metadata including sender, subject, file size
• Handles multiple attachments per email
• Error handling for individual attachments

• email-to-arena.ts - Main email processing logic
• blob-server.ts - HTTP endpoint to serve stored attachments
• README.md - This documentation

• Check the Val Town logs for error messages
• Ensure your Are.na API key has write access to the channel
• Verify the channel slug is correct (case-sensitive)
• Large attachments may take longer to process
