README

Hot Reactor is Hot Reload mechanism for applications. It is built with OpenSwoole development in mind, but it reloads specific commands based on the file changes.

You can install it via composer install or download the project and arrange the .env file with the proper settings.

Setup

There are 2 ways to run the Hot Reactor:

Option 1: run other folders

To run services located in other directories:

Check the .env file for the settings you need to update. The following are the steps to follow:

• Step 1: update the WORKING_DIR environment setting, to point to the directory where the service is located. default: /var/www/html/
• Step 2: update the COMMAND environment setting, to point to the command you want to run. default: /usr/bin/php server.php
• Step 3: update the OBJECTS environment setting, to point to the files you want to watch for changes. default: /var/www/html/|/var/www/html/features/
• Step 4: update the MAIN_PROCESS_NAME environment setting, to customzie your main process name. default: hot-reactor
• Step 5: update FILE_EXTENSIONS environment setting, to specify the file extensions to watch for changes. default: php|env

Hot Reactor comes with a command line tool to run the Hot Reactor. You can run the following command to start the Hot Reactor:

php index.php -w "/path/to/your/service" -c "your-command" -o "your-objects"

As in the example, you can also overwrite the WORKING_DIR, COMMAND and OBJECTS settings via command options.

Option 2: install hot reloaded via composer

To install Hot Reactor via composer, you can run the following command:

composer require lotharthesavior/hot-reactor

After installing the package, you can run the following command to start the Hot Reactor:

vendor/bin/hot-reactor -w "/path/to/your/service" -c "your-command" -o "your-objects"

Important: There is a bug related to when you want to restart an app running sub processes with OpenSwoole\Process. Then, you might need to wait for a SIGKILL at the end of the file so the app restarts gracefully. You do that by adding the following code:

Co::run(function () {
    System::waitSignal(SIGKILL, -1);
});
