var hyperstream = require('hyperstream');
var fs = require('fs');
var hs = hyperstream({
'#a': fs.createReadStream(__dirname + '/a.html'),
'#b': fs.createReadStream(__dirname + '/b.html')
});
var rs = fs.createReadStream(__dirname + '/index.html');
rs.pipe(hs).pipe(process.stdout);
$ node example/hs.js
<html>
<body>
<div id="a"><h1>a!!!</h1></div>
<div id="b"><b>bbbbbbbbbbbbbbbbbbbbbb</b></div>
</body>
</html>
var hyperstream = require('hyperstream')
Return a duplex stream that takes an html stream as input and produces an html
stream as output, inserting the streams given by streamMap at the css selector
keys.
If streamMap values are strings or functions, update the contents at the css
selector key with their contents directly without using a stream.
If streamMap values are non-stream objects, iterate over the keys and set
attributes for each key.
These attributes are special. Each attribute can be a string, buffer, or stream:
_html - set the inner content as raw html_text - set the inner content as text encoded as html entities_append, _appendText - add text to the end of the inner content encoded as
html entities_appendHtml - add raw html to the end of the inner content_prepend, _prependText - add text to the beginning of the inner content
encoded as html entities_prependHtml - add raw html to the beginning of the inner contextFor example, to set raw html into the inner content with the _html attribute,
do:
hyperstream({
'#content': {
_html: stream,
'data-start': 'cats!',
'data-end': 'cats!\ufff'
}
})
You can also specify string operations for properties with an object instead of a string. The object can have these properties:
appendprependObject properties are particularly handy for adding classes:
hyperstream({
'.row': {
class: { append: ' active' }
}
})
which turns:
<div class="row"><b>woo</b></div>
into:
<div class="row active"><b>woo</b></div>
