A TransformStream that detects charset from http client response and content, and converts HTML to utf-8. Besides, replaces charaset strings in a
<meta> tag to "UTF-8".
var HTMLCharset = ;var converter = ;
Returns a new TransformStream that detects charset from http client response and chunked html content, finally converts html content to UTF-8 strings Buffers. First, it stores html contents Buffers as big as bufferSize (default: 512 bytes) and detects charset strings. Then, it converts html contents to UTF-8 strings Buffers. At this time, the charset strings in a
meta tag is replaced to "UTF-8" (e.g.
<meta http-equiv="Content-Type" content="text/html; charset=EUC_JP"> will be replaced to
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">). Finally, you can get UTF-8 html strings Buffers. If the charset couldn't be detected, this stream passes html contents with no modification.
var request = ;var HTMLCharset = ;var http = ;http;
req writes html contents to
converter receives string/Buffer contents, detects charset, converts contents to UTF-8 Buffer, replaces charset strings in a
<meta> tag to
"UTF-8", and writes UTF-8 Buffer contents to
srvRes receives UTF-8 Buffer contents and sends them to browser.
