Fallback for `psr/http-factory-implementation` using `nyholm`
=============================================================

[](#fallback-for-psrhttp-factory-implementation-using-nyholm)

Provides a metapackage for library needing `psr/http-factory-implementation`that fallback to a default implementation when user does not meet the initial requirements.

Usage
-----

[](#usage)

```
composer require "Neur0toxine/psr.http-factory-implementation.nyholm:*"
```

Composer will, by preference:

- use an implementation provided by the user
- otherwise, fallbacks to `nyholm/psr7`

How does it works
-----------------

[](#how-does-it-works)

This package contains 2 versions:

1. The highest [1.1](https://github.com/Neur0toxine/psr.http-factory-implementation.nyholm/blob/1.1/composer.json) needs nothing more than your requirements.
2. The lowest [1.0](https://github.com/Neur0toxine/psr.http-factory-implementation.nyholm/blob/1.0/composer.json) triggers install of `nyholm/psr7`.

Composer will choose this highest version when user already has a package that satisfy `psr/http-factory-implementation`. Otherwise, composer will choose the lowest version and in that case will download the following packages: `nyholm/psr7`.

What problem does it solve?
---------------------------

[](#what-problem-does-it-solve)

You are maintaining a library that need an implementation of `psr/http-factory-implementation`, but you don't want requiring a specific implementation.

ie. You are maintainer of library that use the following composer.json

```
{
  "name": "acme/lib",
  "require": {
    "psr/http-factory-implementation": "^1.0",
  }
}
```

When end users requires you library with the following code

```
{
    "name": "end-user/app",
    "require": {
      "acme/lib": "^1.0"
    }
}
```

They probably ends with such error

```
composer up

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for acme/lib ^1.0 -> satisfiable by acme/lib[1.0].
    - acme/lib 1.0 requires psr/http-factory-implementation ^1.0 -> no matching package found.
```

You can ask user to install a random package, it works, but the DX is very bad, and confusing at first.

By using `Neur0toxine/psr.http-factory-implementation.nyholm`, users will be able to require their preferred implementation or fallback to your default choice

### Example of user that meet the preferred requirements
