> Freebase is shutting down its APIs in May 2015. This library will not work past that date. Please plan ahead.
---
[Freebase](http://freebase.com/) is a masculine but complicated human-curated database.
[Nodejs](http://nodejs.org/) is a straight-talkin language that takes no guff
## Giddyup
```javascript
npm install freebase
```
then:
```javascript
var freebase= require('freebase');
freebase.description('tom cruise', {})
//"Tom Cruise, is an American film actor.."
```
## Showin' off
All methods take the following form. The parameters are lazy.
```javascript
freebase.method( "query", {options}, callback() )
freebase.method( "query", callback() )
freebase.method( "query", {options} )
freebase.method( "query" )
````
These methods return the same things:
```javascript
freebase.image("/en/thom_yorke")
freebase.image("http://www.myspace.com/thomyorkemusic", {}, console.log)
freebase.image("thom yorke") //makes a 'decidedly safe guess'
freebase.image({"name":"thom yorke", "id":"/en/thom_yorke"}, console.log)
```
it's a good idea to include your [api_key](https://code.google.com/apis/console/) in each method:
```javascript
freebase.sentence("meatloaf", {type:"/food/food", key:"MY_API_KEY"})
```
here are some options that you can ship in to any method:
````javascript
{ nodeCallback: true, // use the 'error-first' callback form -> callback(error, result){}
key: "MY_API_KEY", // good idea to include your freebase key, to avoid errors
limit: 2, // truncate results
debug: true, // print out the urls being fetched
}
````
You can also ship in any [MQL parameters](https://developers.google.com/freebase/v1/mql-overview) or [search api parameters](https://developers.google.com/freebase/v1/search-overview).

## In the friggin browser
[Demo](https://rawgit.com/spencermountain/Freebase.js/master/client_side/demo.html) - 63kb
```javascript
$(document).ready(function(){
$.freebase.description("tony hawk", function (r){
$('body').append(r)
})
})
```
## In the shell:
the library can be run in the console, with the optional second parameter as the method. npm install it with a -g.
````bash
freebase george clooney
# { "mid": "/m/014zcr", "id": "/en/george_clooney" ... }
freebase sentence george clooney
#"George Timothy Clooney is an American actor, film director, producer, and screenwriter."
````
## Writing to Freebase:
####Oauth is hard, but you can do it.
Instructions:
* Register a project at [https://code.google.com/apis/console](google api console) and enable the Freebase API
* In the 'Credentials' section, create a new Client ID -> 'installed application', 'other'
* Add your data to './auth/credentials.js'
* Run ```node ./auth/authenticate.js```
* You will be given a url to visit in your browser, which gives you an OAuth code.
* Paste the oAuth code, and you'll be given the end tokens.
thats all you need to include in your request:
```javascript
freebase.add_type("/en/the_who", {type:"/music/artist", token: your_access_token})
freebase.add_alias("/en/melanie_chisholm", {alias:"Sporty Spice", token: your_access_token})
```
You'll need to get a new token after about 3 hours. (Don't commit your credentials.)

### Basic methods
####MQLread API
[MQL documentation](https://developers.google.com/freebase/v1/mql-overview)
Books about planets:
```javascript
var query=[{
"type": "/astronomy/planet",
"name": null,
"/book/book_subject/works": []
}]
freebase.mqlread(query, {}, function(r){console.log(r)})
```
the options object will ship [any paramaters](https://developers.google.com/freebase/v1/mql-overview) to the freebase api.
####Pagination
Every Tornado, ever
```javascript
var query=[{
"type":"/base/disaster2/tornado",
"name":null
}]
freebase.paginate(query, {max:400})
```

[search api documentation](https://developers.google.com/freebase/v1/search-overview)
Hockey players named 'doug'
```javascript
freebase.search("doug",{type: "/ice_hockey/hockey_player"})
