npm install read-art
see test or examples folder for a complete example
read(html|uri [, options], callback)
read-art is designed to be the simplest way possible to make web-article scrape, it supports the definitions such as:
Where
callback(error, article, options)Example scrape by uri?
var read = require('read-art');
read('http://google.com', { overrideCharset: 'utf8' }, function(err, art, options){
if(err){
throw err;
}
var title = art.title, // title of article
content = art.content, // content of article
html = art.html; // whole original innerHTML
});
or
read({ uri: 'http://google.com', overrideCharset: 'utf8' }, function(err, art, options){
...
});
what about simple html?
read('<title>node-art</title><body><div><p>hello, read-art!</p></div></body>', { overrideCharset: 'utf8' }, function(err, art, options){
...
});
or
read({ uri: '<title>node-art</title><body><div><p>hello, read-art!</p></div></body>', overrideCharset: 'utf8' }, function(err, art, options){
...
});
or
read({ html: '<title>node-art</title><body><div><p>hello, read-art!</p></div></body>', overrideCharset: 'utf8' }, function(err, art, options){
...
});
CAUTION title must be wrapped in a title tag and content must be wrapped in a body tag.
A value indicating whether cache body && title.
Kill breaks in the HTML, and convert them to simple <br />.
###options from cheerio
Indicates whether special tags (<script> and <style>) should get special treatment and if "empty" tags (eg. <br>) can have children. If false, the content of special tags will be text only.
For feeds and other XML content (documents that don't consist of HTML), set this to true. Default: false.
If set to true, all tags will be lowercased. If xmlMode is disabled, this defaults to true.
Returns the innerHTML with the leading, trailing, and repeating white spaces stripped.
ϟ Blazingly fast: read-art is based on cheerio(cheerio is about 8x faster than JSDOM), and the article marking strategy actualized by RegExp, it's supper fast and cost less memory.
❤ Hit the target: the bonus algorithm make spider or scraper more easier to grab the article title & content.
❁ Fetch: if you only wanna fetch html body by url, fetch is an amazing library, i've test it with request, it's really fast and cost less memory, reference to Vadim's Issue and more important, fetch could avoid messy code in 99.9% conditions, event some pages using utf8 in response headers, but gb2312 in html head meta, we only need to use the overrideCharset option, e.g.:
read('http://game.163.com/14/0506/10/9RI8M9AO00314SDA.html', {
overrideCharset: 'gbk'
}, function(err, art){
...
});
to refrain from the crazy messy codes.
cd to the read-art directory and install all the dependencies library.
./node_modules/.bin/mocha -R Spec -t 10000
luin/node-readability is really good, lots of hit points, easy to use, but the problem is - it's too slow, make me mad. it was based on JSDOM, as you known, the HTML must be strict, you can not make any mistake, e.g.:
<P>Paragraphs</p>
<p>My book name is <read-art></p>
<div><p>Hey, dude!</div>
all above will cause hiberarchy errors. and otherwise, JSDOM is a memory killer.
bndr/node-read is amazing, and i've worked on this for a while, but it's hard to communicate with Vadim(we are in a different timezone), and we have very different ideas. so i decided to write it on my own.
