schemizeのnode.js版作った

Posted at

shcemizeという、JSONからJSON Schemaを生成する便利なGemがある。

schemizeを使うためだけにGemfileを書くのが嫌だったので、node-schemizeを作った。

// とりあえずグローバルにインストール
$ npm install -g schemize

// デフォルト
$ echo '{ "key": "value" }' | schemize
{"type":"object","properties":{"key":{"type":"string"}}}

// プリチー
$ echo '{ "key": "value" }' | schemize --pretty
{
  "type": "object",
  "properties": {
    "key": {
      "type": "string"
    }
  }
}

// プリチーはインデント数と"tab"が指定可能
$ echo '{ "key": "value" }' | schemize --pretty tab
{
        "type": "object",
        "properties": {
                "key": {
                        "type": "string"
                }
        }
}

yamlはyaml屋ということで、yamlを出力したい場合はjs-yaml等を使ってください。

$ npm install -g js-yaml
$ echo '{ "key": "value" }' | schemize | js-yaml
type: object
properties:
  key:
    type: string

バグ等はissueにて頼む!
