Create badges to display if a given version of a programming language, framework etc. is still supported or if it's EOL (end-of-life).

Supported products and version ranges can be seen in versions.ts. If there are some versions missing or you don't find a programming language/framework you would like to use it with, PRs are welcome.

Version Badge exposes 3 endpoints that are run as Netlify Functions.

All endpoints require two parameters, lang and version.

• lang: name of the language/framework (as written in versions.ts)
• version: semver compatible version identifier, for example 1.2.3, 2.5, 4.6.x, >=1.0.0, v2 etc.

Returns Shields IO compatible data to generate a live badge image.

Endpoint: https://version-badge.netlify.app/shields/:lang/:version

Combine with https://img.shields.io/endpoint and provide version-badge endpoint as url query parameter.
Add style query parameter to use a different badge image style (see https://shields.io/#styles for available styles).

More information about using Shields IO with custom endpoint: https://shields.io/endpoint

Shields IO supports caching badges and Version Badge currently sets the cache to 24h (but you can override it with an URL parameter if needed, read more from the link above).

Note, any characters that require URL encoding in the Version Badge URL need to be double encoded as the URL is also passed as URL parameter to Shields IO, e.g. >= (see examples).

![php 7.1](https://img.shields.io/endpoint?url=https://version-badge.netlify.app/shields/php/7.1)

![nodejs 16](https://img.shields.io/endpoint?style=flat-square&url=https://version-badge.netlify.app/shields/nodejs/%253E%253D16)

Returns Badgen compatible data to generate a live badge image.

Endpoint: https://version-badge.netlify.app/badgen/:lang/:version

Combine with https://badgen.net/https prefix and without https://. Use https://flat.badgen.net/https prefix for flat badge image style.

More information about using Badgen with custom endpoint: https://badgen.net/https

Note, remember to URL encode any characters that require it, e.g. >=

![php 7.1](https://badgen.net/https/version-badge.netlify.app/badgen/php/7.1)

![nodejs 16](https://flat.badgen.net/https/version-badge.netlify.app/badgen/nodejs/%3E%3D16)

Returns EOL informations as JSON. Can be used to create custom implementations of version EOL check. For example if you want to integrate it in a CI pipeline etc.

Endpoint: https://version-badge.netlify.app/version-eol

Response format:

type VersionResult = {
    lang: string;
    version: string;
    eol: DateString | "current"; // Date string as YYYY-MM-DD
    isEol: boolean;
    isNearEol: boolean; // true when EOL upcoming within 6 months
}

Can be called with either GET or POST request.

With GET request, provide lang and version as query parameters.

With POST request, send JSON body with an object that has keys lang and version.

GET https://version-badge.netlify.app/version-eol?lang=nodejs&version=16.0

POST https://version-badge.netlify.app/version-eol
With body { "lang": "nodejs", "version": "16.0" }

Response:

{
    "version": "16.x",
    "eol": "2024-04-30",
    "lang": "nodejs",
    "isEol": false,
    "isNearEol": false
}
