Folivoro Composer-Dropin-Installer
==================================

[](#folivoro-composer-dropin-installer)

A Composer plugin that copies files from any installed package into a target directory — either resolved from the root package's `installer-paths` configuration, or a direct path relative to the project root.

Why
---

[](#why)

Some packages need to place a file at a specific location in the project — for example, a WordPress MU-plugin bootstrapper or a shared config file. The standard `composer/installers` approach installs an entire package directory. This plugin does one thing: copies declared files to the right place.

Installation
------------

[](#installation)

```
composer require folivoro/composer-dropin-installer
```

Usage
-----

[](#usage)

In any package that wants to install dropin files, add to `composer.json`:

### Single file (via `installer-paths`)

[](#single-file-via-installer-paths)

```
{
    "extra": {
        "dropin": {
            "file": "my-plugin.php",
            "target-type": "wordpress-muplugin",
            "target-dir": "my-plugin"
        }
    }
}
```

### Single file (via direct path)

[](#single-file-via-direct-path)

```
{
    "extra": {
        "dropin": {
            "file": "pint.json",
            "target-path": "."
        }
    }
}
```

### Multiple files

[](#multiple-files)

```
{
    "extra": {
        "dropins": [
            { "file": "pint.json", "target-path": "." },
            { "file": "phpstan.neon", "target-path": "." },
            { "file": "rector.php", "target-path": "." }
        ]
    }
}
```

The root project must have `installer-paths` configured when using `target-type`:

```
{
    "extra": {
        "installer-paths": {
            "public/extensions/components/{$name}/": [
                "type:wordpress-muplugin"
            ]
        }
    }
}
```

Given the above, `my-plugin.php` will be copied to:
