local-image-server

1. a simple image hosting service used nodejs
2. running without mysql or mongodb, lowdb is required again (I'm a big fan of lodash)
3. base64 or image from web URL is supported, besides the form submit
4. resize the image to your expected and return base64
5. all images stay in your disk

Getting started

1. install
   yarn

2. start
   yarn start

3. finally
   two server have started, one is image server, the other one is data server.(default port is 9071 and 9072)

return base64 string

why not chevereto

1. the only api for upload used get method, so you cannot upload some image within large size
2. cannot get image with the specific size and format
3. bad pagination

todo

1. search images in a disk and generate the specific info in the database
2. build an app for users like chevereto, it should have albums /pagination / tags / full-text search /multiple users
