How can I check latest available version of Symfony with any API? - api

Question

I want to get latest available version of Symfony Framework. Can I get it with any available API (maybe with Composer or any web services)?

Answer 1

The official Symfony roadmap API can give you the most recent LTS, Stable, and Beta versions available.
Making a call to
https://symfony.com/roadmap.json?version=all
Will return something similar to
{
"symfony_versions": {
"lts": "2.8.5",
"stable": "3.0.5",
"beta": "3.1.0-DEV"
},
"latest_stable_version": "3.0",
"version": "all",
"error_message": "Wrong version format (should be X.Y or X.Y.Z where X, Y, and Z are integers)."
}
Note that this is an undocumented use of the API, as you trick it by not supplying a valid version number. This prompts the API to return a JSON object listing the current versions. Although undocumented, I think you can safely use this because the Symfony project has a strong history of maintaining backwards compatibility.

packagist.org actually has an undocumented API. All you have to do is go to any package page and add .json to the URL.
For example, this is the page for symfony/symfony and its respective JSON formatted version.
The path "package"->"versions" is an object whose keys are version numbers and whose values are package description objects. These have a version_normalized key that you could use to sort the packages to find the latest version.
"package": {
"name": "symfony/symfony",
"description": "The Symfony PHP framework",
"time": "2011-09-29T17:29:54+00:00",
"maintainers": [
{
"name": "fabpot"
}
],
"versions": {
...
"v2.5.8": {
"name": "symfony/symfony",
"description": "The Symfony PHP framework",
"keywords": [
"framework"
],
"homepage": "http://symfony.com",
"version": "v2.5.8",
"version_normalized": "2.5.8.0",
...

Packagist is your friend (that's where the composer stuff comes from)
https://packagist.org
https://packagist.org/feeds/package.symfony/symfony.rss
https://packagist.org/feeds/package.symfony/symfony.atom
EDIT
2nd solution is via github API
