Removes .flashignore references from Flash documentation and adds a new section documenting the built-in ignore patterns that now replace it. Users should migrate any custom patterns to .gitignore. The environment files pattern has been updated to .env.* to reflect that all .env variants (not just .env.local) are excluded from deploy artifacts.

Agent Response

I've created a documentation update for PR #220 which replaces .flashignore with built-in ignore patterns.

Summary of changes:

1. Removed .flashignore from project structure trees in:

   • flash/apps/initialize-project.mdx
   • flash/cli/init.mdx
   • flash/apps/build-app.mdx

2. Updated troubleshooting guidance (flash/troubleshooting.mdx) to recommend adding large files to .gitignore instead of .flashignore

3. Updated deploy-apps.mdx to reference the new built-in ignore patterns documentation instead of .flashignore

4. Added new "Built-in ignore patterns" section to flash/cli/build.mdx documenting:

   • All automatically excluded file patterns (build artifacts, virtual environments, IDE files, environment files, tests, and documentation)
   • How to add custom exclusions via .gitignore
   • A deprecation note for users migrating from .flashignore

The suggestion is ready for review at https://app.gopromptless.ai/suggestions/e1498a5f-d4ab-4373-84b2-b6c521884de4

runpod/flash PR #280: fix: exclude .env files from deploy artifact by default

Agent Response

I've reviewed PR #280 and updated the documentation accordingly.

Summary

PR #280 adds .env and .env.* to Flash's built-in ignore patterns, preventing accidental upload of local development secrets (like API keys in .env files) to deployed workers. This is a security improvement.

Documentation Update

I updated the existing suggestion for Flash .flashignore deprecation to accurately reflect this change:

Change made in flash/cli/build.mdx:

• Updated the "Environment files" row in the built-in ignore patterns table from .env, .env.local to .env, .env.*

This ensures the documentation accurately shows that all .env variants (.env.local, .env.production, .env.staging, etc.) are excluded from deploy artifacts, not just .env.local.

The change was added to the existing suggestion since it directly relates to the same feature: Flash's built-in ignore patterns that replaced .flashignore.
