To merge a few swagger JSON files into one.
Install Go if you don't have one.
https://golang.org/doc/install
Install the command line tool first.
go get github.com/CheatXGO/go-swagger-merger
The command below will merge /data/swagger1.json /data/swagger2.json and save result file in the /data/swagger.json. The library supports more than two files to merge. You can add more paths to the list /data/swagger3.json, /data/swaggerN.json.
go-swagger-merger -o /data/swagger.json -t your_title -v your_version /data/swagger1.json /data/swagger2.json
Attention. The order of the files is essential, and the following file overwrites the same fields from the previous file.
