以檔案為後端的網站框架

許多安全性漏洞會發生，通常是因為外在世界能夠控制在伺服器上執行的服務。舉
例來說，SQL 插入攻擊就是藉由如網站表格的東西，在資料庫上執行特定指令的方
法。靜態檔案的架構則能夠防止這種事情（的確，有人能夠直接入侵伺服器本身—
不用藉由在伺服器上其他不相關的服務，也不用藉由滲入資料中心—但這對
任何的
電腦系統來說都是個漏洞）。
熟悉的工具
人們很習慣使用文字編輯器。他們知道要如何將檔案儲存至磁碟上。這個程序讓使
用者能夠取用他們所習慣的工具，而不是在以 JavaScript 所建立的 WYSIWIG 編輯
器上胡來。
遠端使用者在開始時可能會遇到一些困難。他們會需要使用如 FTP、
scp
或
rsync
等
工具，來將本地內容推播至伺服器上。這對某些人來說可能較困難。然而，這些指
令對任何能夠使用命令列工作的人來說，是相對簡單的。你能夠對這些人提供任何
的雲端服務，來在電腦之間同步檔案。
備份容易
現在，備份與回復都變得簡單，因為備份系統只需要跟標準檔案系統溝通即可。每
個備份工具都能夠處理純文字檔案。與之相比，備份以及回復資料庫變得很痛苦。
它通常需要你使用特別以及是資料庫限定的工具，有些還會建立特別的格式。
實作
有了上述的概念，實作相對來說是很直覺的。我們擁有一個儲存原始資料的純文字文
件的目錄。該目錄是由
inotifywait
或是類似的工具所監控。當目錄的內容變更時，
inotifywait
會使用變更內容的檔案當成參數，呼叫一個處理的腳本程式。當檔案的
內容被建立或是變更時，該腳本程式需要能夠建立新的 ...
