Diffbot API for CoffeeScript
Preface
This brief documentation doesn't include full API methods and parameters. Full library API documentation in HTML format could be found in doc folder.
Installation
Library can be installed from npm
npm install diffbot-coffeeConfiguration
Obtaining CoffeeScript Diffbot client is simple as that:
{Client} = require 'diffbot-coffee'
client = new Client '<your_key>'Usage
Article API
Assume that we have our client configured. In order to use Automatic Article API we need to instantiate Article API instance first:
article = client.article 'http://someurl.com', ['title']After instantiation we can use our client object to retrieve information
article.load (error, result) ->
if error?
console.error error
else
console.log resultIf your content is not publicly available (e.g., behind a firewall), you can use send method or article object
article = client.article 'http://diffbot.com', ['title']
content = '<html><head><title>Test title</title></head><body>Test body</body></html>'
article.send content, (error, result) ->
if error?
console.error error
else
console.log resultThere is also alternative syntax for creating article objects
article = client.article
url: 'http://someurl.com'
fields: ['title']
console.log article.url
console.log article.relative_url
article.load (error, result) ->
if error?
console.error error
else
console.log result.typeSimilar syntax is available for all objects.
Page Classifier API
Calling Page Classifier API is also pretty simple:
pageclassifier = client.pageclassifier 'http://someurl.com'
pageclassifier.load (error, result) ->
if error?
console.error error
else
console.log result.typeCrawlbot API
Calling Crawlbot API is similar to calling Article API. One thing worth to notice is that Crawlbot API Version 2 requires apiUrl which will be used to perform crawling. Library implementation makes possible to avoid using urls here. Instead we will use Article API:
crawler = client.crawlbot 'my-bot', ['http://someurl.com', 'http://foo.com'], client.article('', ['title']).url
crawler.create (error, result) ->
if !error?
console.log resultor alternatively we can set optional parameters as object
crawler = client.crawlbot 'my-bot',
seeds: ['http://someurl.com', 'http://foo.com']
apiUrl: client.article('', ['title']).url
crawler.create (error, result) ->
if !error?
console.log resultCrawler object supports next methods
crawler.pause
crawler.restart
crawler.delete
crawler.data
crawler.statusUsage is pretty simple
or alternatively we can set optional parameters as object
crawler = client.crawlbot 'my-bot',
seeds: ['http://someurl.com', 'http://foo.com']
apiUrl: client.article('', ['title']).url
crawler.create (error, result) =>
if !error?
crawler.delete (error, result) =>
if !error? and result
console.log 'Crawler successfully deleted'
