node.js解析页面并捕获外部前端js错误

Question

是否可以解析具有某些js错误（例如，“未定义$”）的外部页面http://example.com ，捕获这些错误并通过console.log（）打印它们？

Answer 1

对的，这是可能的。 基本上，您需要下载页面并在无头浏览器（例如PhantomJS）中呈现它。

有人已经这样做了： http : //npmjs.com/package/phantom-check

$ phantom-check http://example.com
Phantom is checking http://example.com

[info] [phantom] Starting...
[info] [phantom] Running suite: 2 steps
[debug] [phantom] opening url: http://example.com/, HTTP GET
[debug] [phantom] Navigation requested: url=http://example.com/, type=Other, willNavigate=true, isMainFrame=true
[debug] [phantom] url changed to "http://example.com/"
[debug] [phantom] Successfully injected Casper client-side utilities

Page http://example.com has no errors
