## HTML Canvas

* BeginPath to refresh previous moveTo
* FillStyle to setup color
* stroke to draw the line
* draw circle in canvas by using arc(x, y, radius, startAngle, endAngle)
  * <https://www.w3schools.com/tags/canvas_arc.asp>

swagger-node, create template project of node

swagger-ui

swagger-mock

Add Authorize in Swagger API

1. Write Swagger Spec as following:![](/files/-LfNCpHQY0fhHepd2FKv)
2. Declare security need inside API's schema

   ![](/files/-LfNCpHShsOkJ08E8Zuv)
3. Prepare swaggerSecurityHeandlers and verified API there
4. ```
   var config = {
     appRoot: __dirname, // required config
     swaggerSecurityHandlers: {
       Bearer: function (req, authOrSecDef, scopesOrApiKey, callback) {
         console.warn('apiKey', scopesOrApiKey);
         if (scopesOrApiKey === TOKEN) {
           callback();
         } else {
           callback(new Error('API Key not matched'))
         }
       },
     },
   };
   ```

## Ideas

MapFriends

* 以看到事件距離自己目前地點的距離收費，e.g. 1km 的半徑免費 以上收費
* 要以聲音進行溝通，無文字
* 可以上傳大頭貼與FB/Google 登入 或匿名
* 匿名如何建立事件？ 必須留email ?
* Disable file cache.

`/etc/nginx/nginx.conf`

`sendfile off`

### Stored Bitbucket password not updated

`remote: Too many invalid password attempts. Try logging in through the website with your password.`

`fatal: unable to access 'https://zhang699@bitbucket.org/zhang699/rotan.git/': The requested URL returned error: 403`

Solution: Update MAC's KeyChain
