Versions inconsistency? Composer problem

[Artiom Neganov]

I don't get which version to use and which version docs describe.

If I try the Hello World example from the README with the latest version - it works.
But then I cannot install http-server-router:

And if I switch to the version 1.1.2, I cannot find a proper documentation bescause the current one is not consistent with the classes. There is no HttpServer class for example and etc.

In the docs of Http Server https://amphp.org/http-server/ there is no any mention about versioning.

Hey @OnkelTem!

1. Using examples from amphp/http-server (master branch or v2.0.0 RC3) with latest versions of http-server-router (v1.0.2) should be just fine.

I have no composer issues with composer.json like this:

{
    "require": {
        "amphp/http-server": "^2.0",
        "amphp/http-server-router": "^1.0"
    },
    "minimum-stability": "RC"
}

2. amphp/http-server v2 is still in Release Candidate stage, that's why https://amphp.org/http-server/ documentation is all about version v.1.1

[Niklas Keller]

@krlv Unfortunately, the documentation on our website always points to the default branch currently, so master with the changes for RC.

Ok, I got it.
The problem was that I had "minimum-stability": "dev" in my composer.json.
So when I installed amphp/http-server I got:

amphp/http-server      dev-master 02c7697

And afterwards router doesn't install:

$ composer require amphp/http-server-router

"prefer-stable": true resolved the issue.
