+# Zaim Rest API Sample
+
+## Overview
+
+ZaimのREST API実行サンプルです
+
+## Requirement
+
+* node v10.13.0
+* npm 6.4.1
+
+## Install
+
+### 1. Zaim認証ID取得
+
+https://dev.zaim.net/users/login にログイン  
+[新しいアプリケーションを追加]で適当に入力  
+コンシューマID、コンシューマシークレットをconfig/default.jsonに追記
+
+### 2. ユーザートークン取得
+
+```
+$ npm install
+$ npm run start
+```
+ブラウザで http://127.0.0.1 を開く  
+OAuthの[認証実行]をクリック  
+Zaimの認証画面に移動するので許可する  
+完了画面に移動するがリダイレクトされないので、Chrome開発者ツールなどでソースを表示  
+div.callbackのURL`http://127.0.0.1:4000/auth/callback?〜`をブラウザで開く  
+表示されたtoken、token secretをconfig/default.jsonに追記
+
+## Usage
+
+Install後、`npm run start`で再起動  
+ブラウザで http://127.0.0.1 を開き、ユーザー情報の取得、合計金額の取得を実行すると、Zaimに入力しているデータが表示される
