A V A T A R

Create avatars based on names. The colors are chosen based on the first character. You can save to disk ToDisk or send back over HTTP ToHTTP.

This fork is based off github.com/argylelabcoat/avatar, which is forked from andrew's https://github.com/ae0000/avatar.

All this fork cares about is ditching the logging and os.Exit bits, instead returning error values. This makes it safer to use as a library.

Example

package main

import (
	"github.com/argylelabcoat/avatar"
)

func main() {
	avatar.ToDisk("AE", "../ae.png")

    // Which is the same as
    avatar.ToDisk("Andrew Edwards", "../ae.png")
}

You can pass in a single character as well

// Single initial as well..
avatar.ToDisk("Jet", "../j.png")

HTTP example

Using go-chi (highly recommended HTTP router)

package main

import (
	"fmt"
	"net/http"
	"strings"

	"github.com/argylelabcoat/avatar"
	"github.com/go-chi/chi"
)

func main() {
	r := chi.NewRouter()

	// Get the png based on the initials, You would use it like this:
	//    <img src="http://localhost:3000/avatar/ae/png" width="150">
	r.Get("/avatar/{initials}.png", func(w http.ResponseWriter, r *http.Request) {
		initials := chi.URLParam(r, "initials")

		avatar.ToHTTP(initials, w)
	})

	http.ListenAndServe(":3000", r)
}

TODO

• HTTP example
• Caching
• Custom colors
• Add unique colors that are missing (T-Z,0-9)
