Generating optimized autoloader automatically

Question

I'm working on a simple project using PHP and I'm using PSR-4 autoloading. I just wonder if there's a way to run composer dump-autoload -o on composer install, so that new users won't need to type composer dump-autoload -o to avoid autoloading error

{
    "name": "project/vendor",
    "license": "MIT",
    "authors": [
        {
            "name": "my name",
            "email": "[email protected]"
        }
    ],
    "require": {
        "phpunit/phpunit": "^7.5"
    },
    "autoload": {
          "psr-4": {
              "src\\": "src/"
           }
     },
     "scripts": {
        "run-test": ["./vendor/bin/phpunit tests/calculatorTests.php"]
    }
}

dump-autoload -o is only to create an optimized autoload map for use in production. For development you don't need it, and just a composer install should suffice. – Indomitability

Actually after testing the code on another machine, i executed composer install but after i got an error which was a class is not found, and it worked just fine after executing composer dump-autoload – Silver

That should not happen. Could you update your post to include your full composer.json? – Indomitability

okay i updated the post and here's the link of the screenshot: i.sstatic.net/2oMT7.png – Silver

Answer 1

You may use optimize-autoloader option in composer.json config:

"config": {
    "optimize-autoloader": true
},

However this may be quite annoying on development phase (when generating optimized autoloader is just waste of time and source of problems), so I would rather create some shortcut script for this and encourage users to use it instead of direct composer dump-autoload or composer install. See this answer as an example. Then you can just use

composer install --no-dev -o 

in your script.

Thanks, that's what i was looking for – Silver
