Lorem.space server

The backend of https://lorem.space lives here.

Features

• Scan the directory & categorize the image resources (only JPEG for now)
• Provide HTTP API
• Resize the image resources
• Cache option to store the resized image as a file

How to run

$ go run main.go

$ go run main.go --dir="/IMAGE/DIRECTORY/PATH"

Options

• host: host:port for the HTTP server (string)
• dir: the path of image resources directory (string)
• cache: enable cache (store the result as files in .cache directory) (bool)
• cdn: CDN address to redirect to the cached file path, leave empty to write the file in the HTTP response (string)
• min-width: minimum supported width (integer)
• max-width: maximum supported width (integer)
• min-height: minimum supported height (integer)
• max-height: maximum supported height (integer)

Run binary

To run built binary, visit the release page & download your OS build file. Unzip the downloaded file & make sure about the file execution permissions, then run the app with the arguments in the terminal:

• MacOS & Linux: ./lorem-server --host "127.0.0.1:8080" --dir "~/Pictures"
• Windows: lorem-server.exe -host "127.0.0.1:8080" -dir "C:\Users\USER\Pictures"

Docker

You can pull & run the public docker image from github package registry:

$ docker pull ghcr.io/manasky/lorem-server:latest

Run docker image:

To run the container you must pass the app arguments via the .env file. To this, create a file named .env & set the options in uppercase & snake case format.

An example of .env file:

HOST=0.0.0.0:8080
DIR=/app/images
MIN_WIDTH=20

By this config, the app listens to port number 8080 on the host IP address and scan /app/images/ path (from the container) for the images and limit the width size to a minimum of 20 pixels.

Link directory

Your images directory must link to the container, to this you can use -v arguments while running the container.

Run command

$ docker run --env-file=./.env -p 8080:8080 -v ~/Pictures:/app/images ghcr.io/manasky/lorem-server:latest

• --env-file sets the application environment variables path. here .env file exists in the current path.
• -p 8080:8080 sets up a port forward. the application container will listen to the 8080 port (set in the .env file as HOST). this flag maps the container's port 8080 to port 8080 on the host (here, your localhost).
• ~/Pictures:/app/images sets up a bindmount volume that links the directory /app/images from inside the app container to the directory ~/Pictures on the host machine (here, your system). The app image directory is set in the .env file as /app/images, so here the ~/Pictures is mounted to that.

After container running, the app will scan /app/images which is mounted to the directory ~/Pictures of your system & serves the HTTP server on 127.0.0.1:8080. Visit 127.0.0.1:8080/image for start.
