node-linkedin

Another Linkedin wrapper in Node.js

---> PLEASE SAFE ME!

I started this fantastic project years ago with an aim to help myself and community. Unfortunately, due to my primary job responsibilities, I can no longer maintain this project. Therefore, I am open if someone would like to be a maintainer or feel free to work and start a new one.

Just create a ticket if you are interested to maintain this project and I will add you as an Admininstrator.

IMPORTANT

I'm rewriting this project with latest-code paradigms and promises in node-linkedin@v2.0. There is no deadline or ballpark of release, but I hope to roll it out in upcoming months. It would support ECMA6 classes so that you may extend them in your source code if need to extend an API.

Why?

Good question! Because when I started to use LinkedIn API, I found couple of wrappers but they were not compatible with OAuth2.0, their contributors hadn't made any recent commits for several months and I had to utilize the whole wrapper with nice helper functions as well.

So, I decided to write another wrapper. We need it! So we can also maintain it! However, pull requests are always major and we'd love to see that!

Getting Started

Just like others, it's simple and quick as per standard:

this will install the module and add the entry in package.json. Let's start using it!

var Linkedin = require('node-linkedin')('app-id', 'secret', 'callback');

You may omit the callback URL. However, you must set it later before requesting an authorization code. (This is useful if the callback URL depends on the request (e.g. from multiple domains.)

var Linkedin = require('node-linkedin')('app-id', 'secret');
// ...
Linkedin.auth.setCallback('callback-url');

Before invoking any endpoint, please get the instance ready with your access token.

var linkedin = Linkedin.init('my_access_token');
// Now, you're ready to use any endpoint

Additionally, you can specify options. The following options are supported:

timeout: allows you to specific a timeout (in ms) for the HTTP request. The default is 60 seconds (a value of 60000).
mobileToken: set to true when using an access token received by the LinkedIn Mobile SDK. The default is false.
- See Using Access Tokens from Mobile SDK below for more info

var linkedin = Linkedin.init('my_access_token', {
    timeout: 10000 /* 10 seconds */
});

Requesting an Authorization Code

OAuth 2.0

Since LinkedIn supports OAuth 2.0 (and we regret to use 1.0 for authentication), let's start using it.

The example below uses a routing library like Express. It is not required to use this module, but it's good enough to give a quick walkthrough.

// Using a library like `expressjs` the module will
// redirect for you simply by passing `res`.
app.get('/oauth/linkedin', function(req, res) {
    // This will ask for permisssions etc and redirect to callback url.
    Linkedin.auth.authorize(res, scope);
});

Alternatively, you can leave res out, and the module will respond with the redirect url which you can use to send the HTTP redirect on your own.

var auth_url = Linkedin.auth.authorize(scope);

You may specify a custom state parameter:

Linkedin.auth.authorize(res, scope, 'state');

Callback URL

If you have multiple domains pointing to the same application, you will need to set the callback URL based on the domain that is making the request.

app.get('/oauth/linkedin', function(req, res) {
    // set the callback url
    Linkedin.setCallback(req.protocol + '://' + req.headers.host + '/oauth/linkedin/callback');
    Linkedin.auth.authorize(res, scope);
}

Scope

The scope previously mentioned refers to the data from LinkedIn to which your application is requesting access. This depends on your application's permissions registered with LinkedIn.

var scope = ['r_basicprofile', 'r_fullprofile', 'r_emailaddress', 'r_network', 'r_contactinfo', 'rw_nus', 'rw_groups', 'w_messages'];

Note: The scope need not be static.

Requesting an Access Token

After the user is redirected to LinkedIn to authenticate, they are redirected to your application's callback URL (whether they accept or decline authorization). See the end of Step 2 on the LinkedIn OAuth 2.0 Documentation.

If they accept, be sure to pass the state parameter to verify no CSRF intrusion. This is compared against the state parameter used in authentication.

// Again, `res` is optional, you could pass `code` as the first parameter
app.get('/oauth/linkedin/callback', function(req, res) {
    Linkedin.auth.getAccessToken(res, req.query.code, req.query.state, function(err, results) {
        if ( err )
            return console.error(err);

        /**
         * Results have something like:
         * {"expires_in":5184000,"access_token":". . . ."}
         */

        console.log(results);
        return res.redirect('/');
    });
});

Companies Search

Supports all the calls as per the documentation available at LinkedIn Companies Search API

linkedin.companies_search.name('facebook', 1, function(err, company) {
    name = company.companies.values[0].name;
    desc = company.companies.values[0].description;
    industry = company.companies.values[0].industries.values[0].name;
    city = company.companies.values[0].locations.values[0].address.city;
    websiteUrl = company.companies.values[0].websiteUrl;
});

Companies

Supports all the calls as per the documentation available at: LinkedIn Companies API.

linkedin.companies.company('162479', function(err, company) {
    // Here you go
});

linkedin.companies.name('logica', function(err, company) {
    // Here you go
});

linkedin.companies.email_domain('apple.com', function(err, company) {
    // Here you go
});

linkedin.companies.multiple('162479,universal-name=linkedin', function(err, companies) {
    // Here you go
});

linkedin.companies.asAdmin(function(err, companies) {
    // Here you go
});

linkedin.companies.updates('162479', function(err, company) {
    // Gets all the updates(Posts) along with their details of a company
});

linkedin.companies.getUpdate('162479','UPDATE-c1337-998877665544332211',function(err, companies) {
    // Gets the detail of a single update(Post) of a company
});

Profile

Searches for the profiles as per the criteria.

Logged In User Profile.

linkedin.people.me(function(err, $in) {
    // Loads the profile of access token owner.
});

OR

linkedin.people.me(['id', 'first-name', 'last-name'], function(err, $in) {
    // Loads the profile of access token owner.
});

Profile by Public URL.

linkedin.people.url('long_public_url_here', function(err, $in) {
    // Returns dob, education
});

OR

linkedin.people.url('long_public_url_here', ['id', 'first-name', 'last-name'], function(err, $in) {
    // Returns dob, education
});

Profile by Id.

linkedin.people.id('linkedin_id', function(err, $in) {
    // Loads the profile by id.
});

OR

linkedin.people.id('linkedin_id', ['id', 'first-name', 'last-name'], function(err, $in) {
    // Loads the profile by id.
});

Connections

Invokes LinkedIn's Connections API.

linkedin.connections.retrieve(function(err, connections) {
    // Here you go! Got your connections!
});

Groups

Implements wrapper for LinkedIn Group API and provides interface to invoke API endpoints.

PS: For now, we just have feeds available.

Group discussions by Group ID

linkedin.group.feeds(3769732, function(err, data) {
    // data: variable is ready to use.
});

OR If you want to have custom field selector, take a look at this;

linkedin.group.feeds(3769732, ['field', 'field2', 'field3'] , function(err, data) {
    // data: variable is ready to use.
});

OR even if you want to have custom sorting parameters, you can just pass them as third argument:

linkedin.group.feeds(3769732, ['field', 'field2', 'field3'], {order: 'popularity'}, function(err, data) {
    // data: variable is ready to use.
});

Using Access Tokens from Mobile SDK (experimental)

NOTE: This feature uses an undocumented workaround for accessing the LinkedIn API. As such, this feature may not work in future releases.

Per the LinkedIn docs:

It is important to note that access tokens that are acquired via the Mobile SDK are only usable with the Mobile SDK, and cannot be used to make server-side REST API calls. Similarly, access tokens that you already have stored from your users that authenticated using a server-side REST API call will not work with the Mobile SDK.

As such, attempting to use a mobile access token with this library will cause the REST API calls to return the error Unable to verify access token. It was discovered that there is a workaround for this issue by changing the way in which this library authenticates with the LinkedIn API. This functionality is controlled via the mobileToken option and must be enabled when using an access token received by the Mobile SDK.
