parse-head

A promise to fetch the base, title, link and meta tags out of a Node stream.

The streaming approach helps remaining efficient in spite of malformed or very large HTML documents.

Notice: this module requires node>=4 to work.

Usage

Node API

const parse = require('parse-head');
const fs = require('fs');
 
parse(fs.createReadStream('some/file.html')).then(tags => {
  // ...
});

It happens Buffer and string values are accepted as well:

const parse = require('parse-head');
const fs = require('fs');
 
fs.readFile('some/file.html', (err, buf) => {
  parse(buf).then(tags => {
    // ...
  });
});

Command line

$ cat some/file.html | parse-head
[
  {"http-equiv":"Content-Type","content":"text/html; charset=utf-8","nodeName":"META"},
  {"property":"og:image","content":"...","nodeName":"META"},
  {"innerText":"...","nodeName":"TITLE"},
  ...
]
