Crafatar serves Minecraft avatars based on the skin for use in external applications. Inspired by Gravatar (hence the name) and Minotar.
Image manipulation is done by lwip. 3D renders are created with node-canvas / cairo.
There are usually a few open issues.
We welcome any opinions or advice in discussions as well as pull requests.

Crafatar is now available at http://0.0.0.0:3000.
See the config.js file.
Crafatar stores a lot of images on disk. For avatars, these are 8×8 px PNG images with an average file size of ~90 bytes. This can lead to issues on file systems such as ext4, which (by default) has a bytes-per-inode ratio of 16Kb. With thousands of files with an average file size below this ratio, you will run out of available inodes before running out of disk space. (Note that this will still be reported as ENOSPC: no space left on device).
Consider using a different file system, changing the inode ratio, or deleting files before the inode limit is reached.
Eventually you will run out of disk space and/or redis will be out of memory. Make sure to delete image files and/or flush redis before this happens.
npm testIf you want to debug failing tests:
# show logs during tests
env VERBOSE_TEST=true npm testIt can be helpful to monitor redis commands to debug caching errors:
redis-cli monitor
