swagger-codegenで吐き出されるnpmのpackage名を変更する

swagger-codegenを使って、デフォルトで以下みたいに吐き出すと、タイトルを使用した適当な名前になってしまう

$ swagger-codegen generate -i swagger.json -l javascript -o ./codegen

何かオプションはないのかと、各言語のヘルプを見る。

$ swagger-codegen config-help -l javascript

projectName が使えそうなので、-Dオプションにくっつける。

$ swagger-codegen generate -i swagger.json -l javascript -o ./codegen -DprojectName=my-project

config-help コマンド重要だねというお話でした。
