The inverse of html-inject-meta
const extract = require('html-extract-meta')
process.stdin.pipe(extract(onMeta))
process.stdin.resume()
function onMeta(err, meta) {
...
}extract(cb) returns a transparent trhough stream (its output is the same as its input). Upon having seen the <head> tag in the input, it calls cb(err, meta), where meta has these propertues:
- name
- description
- author
- generator (coming from
<meta name="generator"> - http (an object with http headers coming from
<meta http-equiv>tags
If there are meta tags with name or property attributes containing a colon (:), they are considered "namespaced meta tags" and occur in meta.namespaced. For example, <meta name="twitter:creator" conent="regular"/> shows up as meta.namespaced.twitter.ceator
html-extract-meta < in.html > out.json [--through]
Reads html from stdin and outputs meta json to stdout. if --through is given, outputs meta json to stderr and outputs html to stdout.
