Libravatar library for Nim, Gravatar alternative. Libravatar is an open source federated avatar api and service.

• Your users nor you dont need a Libravatar account if you dont want to, because if Libravatar cant find you it redirects you to your Gravatar, if you have no Gravatar then it returns a default autogenerated image.
• Federation supported passing baseUrl, DNS server discovery is up to you if you want to, Pull Request welcome.
• 404 wont return 404, but a default image, use default="404" for a HTTP 404 Error.
• Uses func so is Side Effects Free, works with Async & MultiSync.
• runnableExamples included, Self-Documented, NEP-1 Ok.
• Best quality avatar sizes are between 80 & 128, 512 may or may not look a little stretched, depends on original quality.
• Tiny and simple but reusable code.
• By design is also a Gravatar library :)

• nimble install libravatar
• You can create an account for free, it only needs an email.

echo email
email = "[email protected]"
getLibravatarUrl(email, size=9, default="404", baseUrl="https://MyCustomFederatedServer.org/avatar/")
echo email
