PROBLEM

Given the following composer.json…

{
  ...
  "scripts": {
    "start": "php -S 0.0.0.0:8080 -t public index.php"
  }
}

When running composer start…

The PHP built-in web server stops with the following error message…

[Symfony\Component\Process\Exception\ProcessTimedOutException]                              
The process "php -S 0.0.0.0:8080 -t public index.php" exceeded the timeout of 300 seconds.  

SOLUTION

There are several ways to extend the timeout value, but here is one way to do it through composer.json.

To extend the timeout value from 300 seconds to 2000 seconds, add the following config block in composer.json:-

{
  ...
  "scripts": {
    "start": "php -S 0.0.0.0:8080 -t public index.php"
  }
  "config": {
    "process-timeout": 2000
  }
}

To disable web server timeout completely, set process-timeout to 0:-

{
  ...
  "scripts": {
    "start": "php -S 0.0.0.0:8080 -t public index.php"
  }
  "config": {
    "process-timeout": 0
  }
}
