A fully testable, dependency light, Flickr API wrapper. Authenticates and makes web requests
I know there are several existing node flickr modules, but... I thought the community could use one with the following features:
1 - Instantiate the flapi client:
var Flapi = ;var flapiClient =oauth_consumer_key : FLICKR_KEYoauth_consumer_secret : FLICKR_SECRET;
2 - Listen for an http request from flickr and respond
var server = http;
3 - Authenticate your application
4 - When application authentication is finished, prompt users to authenticate with your app by giving them the app auth url.
var url = flapiClient;
5 - Get the user's access token to make individual requests.
6 - Make requests on the user's behalf
Once you've authorized your application and have permissions from a user, you should be able to make api requests on their behalf.
With the exception of photo uploading, all api methods match the flickr documentation. To get a listing of photos, you'll need a
user_id and the user's access token (the
api_key is automatically sent via the access token). The request can be completed with the following:
method- The flickr API Method
params- Any API options to send
accessToken- A user's unique access token
next- The callback used when the api call is complete
To upload a photo, use the method
upload and pass the file path as param. Example:
According to the flickr documentation, you should be able to set your application's permission set (
delete) from the edit screen of your app. I've never been able to find these settings. Instead, you can set it in the flickr module constructor with the
var flapiClient =oauth_consumer_key : FLICKR_KEYoauth_consumer_secret : FLICKR_SECRETperms : 'delete';
Some of flickr's api methods don't require authorization (ex:
flickr.interestingness.getList). To use these without user authentication, omit the
accessToken option from the api call:
API errors are passed directly to the next function. You can catch them by checking the stat property of the data returned. In most scenarios a message property should also be passed.
If you're looking to have a client make the http request, delay the request for some reason, or want to handle the request on your own... you can prevent the call to flickr by passing the option
preventCall : true. Regardless of this option, the full url of the intended request will always be passed back.
var flickrAPIurl = flapiClient;
To keep users from having to authenticate every time your node application restarts, you'll need to persist your application's
oauth_token_secret as well as each user's individual
To instantiate the client with a token and secret, pass those properties when creating the object.
var flapiClient =oauth_consumer_key : FLICKR_KEYoauth_consumer_secret : FLICKR_SECREToauth_token : FLICKR_OAUTH_TOKENoauth_token_secret : FLICKR_OAUTH_TOKEN_SECRET;
You only need to authorize your application once. If you're passing the token and secret, you can skip steps 2 and 3 described in the quick start above.
Using this module within express or any other node server framework should be fairly straight forward. Check out the examples directory of this project for more details.
To run the tests, please make sure you've installed the project's dev dependencies and have the following environment variables set:
FLICKR_KEY- Your flickr application's key
FLICKR_SECRET- Your flickr application's secret
FLICKR_USERNAME- Your flickr user name, used to simulate a yahoo and flickr app authentication flow
FLICKR_PASSWORD- Your flickr password, used to simulate a yahoo and flickr app authentication flow
make test from the root of the project will run all tests in the correct order.
On occasion, the numerous flickr redirects required to simulate authentication will fail. This causes every subsequent test to then fail. If you're running tests and experience this oddity, just run again.
You can skip the auth steps and still test all the API methods by running
make test-without-auth. For this to work, you'll also need the following environment variables set:
FLICKR_OAUTH_USER_TOKEN- Can retrieve this from the standard auth above.
FLICKR_OAUTH_USER_SECRET- Can retrieve this from the standard auth above.
FLICKR_NSID- Can retrieve this from the standard auth above.
FLICKR_USERNAME- Not currently used in the tests, but good to include anyways
