Koa plugins

## Required
yarn add koa koa-router koa-views koa-body ejs nodemon

## If type orm used
yarn add -D @types/koa @types/koa-router  @types/koa-views


## TypeScript sometimes not able to transcript body from ctx.request.body
For that add this in tscongig:
"compilerOptions": {
      "types": ["koa-body"],
      }
