# Fallback for `psr/http-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
|
|
|
|
```shell
|
|
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
|
|
|
|
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.
|
|
|
|
1. 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?
|
|
|
|
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
|
|
```json
|
|
{
|
|
"name": "acme/lib",
|
|
"require": {
|
|
"psr/http-factory-implementation": "^1.0",
|
|
}
|
|
}
|
|
```
|
|
|
|
When end users requires you library with the following code
|
|
```json
|
|
{
|
|
"name": "end-user/app",
|
|
"require": {
|
|
"acme/lib": "^1.0"
|
|
}
|
|
}
|
|
```
|
|
|
|
They probably ends with such error
|
|
|
|
```shell
|
|
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
|
|
|
|
```json
|
|
{
|
|
"name": "end-user/app",
|
|
"require": {
|
|
"acme/lib": "^1.0",
|
|
"third-party/provide-implementation": "^1.0"
|
|
}
|
|
}
|
|
```
|
|
```shell
|
|
composer up
|
|
...
