Development

The dependencies of this package are managed by Go Modules.

Clone this repo:

git clone https://github.com/linksmart/thing-directory.git
cd thing-directory

Compile from source:

go build

This will result in an executable called thing-directory (linux/macOS) or thing-directory.exe (windows).

Copy sample configuration files for server and JSON Schema into conf directory:

mkdir -p conf
cp sample_conf/thing-directory.json wot/wot_td_schema.json conf

conf is the default directory for configuration files. This can be changed with CLI arguments.

Get the CLI argument help (linux/macOS):

$ ./thing-directory -help
Usage of ./thing-directory:
  -conf string
        Configuration file path (default "conf/thing-directory.json")
  -schema string
        WoT Thing Description schema file path (default "conf/wot_td_schema.json")
  -version
        Print the API version

Run (linux/macOS):

$ ./thing-directory

To build and run together:

go run .
