From 8ccd8fb7dec31938da263ff92d4267146e04549a Mon Sep 17 00:00:00 2001 From: Rob Di Marco Date: Tue, 9 Sep 2025 17:35:21 -0400 Subject: [PATCH 1/3] Add separate frontend and backend port configuration for demo command MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement ATXP-243: Allow users to specify separate frontend and backend ports when running the demo, replacing the single --port option with more granular control. ## Changes Made ### Command Line Interface - Replace `--port, -p` with `--frontend-port, --fp` and `--backend-port, --bp` - Update default ports: frontend 3000, backend 3001 (matching atxp-express-example defaults) - Maintain backward compatibility by using sensible defaults ### Configuration Management - Generate .env files for both frontend and backend directories with appropriate port settings - Backend .env: `PORT` and `FRONTEND_PORT` (for CORS configuration) - Frontend .env: `PORT` and `REACT_APP_BACKEND_PORT` (for proxy configuration) - Graceful fallback if .env creation fails (uses environment variables) ### Updated Documentation - Comprehensive help text with new port options and examples - Clear usage examples showing frontend/backend port combinations - Updated default port information throughout ## Implementation Details The demo command now: 1. Parses separate frontend/backend port arguments 2. Creates appropriate .env files in the cloned repository 3. Passes environment variables to the demo process 4. Uses frontend port for browser opening and user messaging This integrates seamlessly with the atxp-express-example repository's existing port configuration system implemented in PR #6. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- packages/atxp/src/help.ts | 17 +++++++----- packages/atxp/src/index.ts | 20 ++++++++++---- packages/atxp/src/run-demo.ts | 52 ++++++++++++++++++++++++++++++----- 3 files changed, 70 insertions(+), 19 deletions(-) diff --git a/packages/atxp/src/help.ts b/packages/atxp/src/help.ts index 4e3a27c..ec58e5d 100644 --- a/packages/atxp/src/help.ts +++ b/packages/atxp/src/help.ts @@ -16,18 +16,21 @@ export function showHelp(): void { console.log();

Now each service (frontend/backend) reads its PORT from its own .env file, allowing them to run on separate ports correctly.
