NodeJS LinkedIn API

NodeJS Wrapper API for LinkedIn API, written in TypeScript.
No tokens are needed for using this API, only a working LinkedIn account.

Installation

npm install @khanhtranngoccva/linkedin-private-api

Example usage

Check out the post I've written that describes a great example of how to use this library.
Also, see a list of examples here.

import { Client } from 'linkedin-private-api';

const username = process.env.USERNAME as string;
const password = process.env.PASSWORD as string;

(async () => {
  // Login
  const client = new Client();
  await client.login.userPass({ username, password });
  
  // Search for React development jobs in Israel
  const jobsScroller = await client.search.searchJobs({
    keywords: 'React',
    filters: { location: 'Israel' },
    limit: 20,
    skip: 5,
  });

  const [someReactJobHit] = await jobsScroller.scrollNext();
  const jobCompanyName = someReactJobHit.hitInfo.jobPosting.companyDetails.company.name;

  // Fetch the job's company
  const companiesScroller = await client.search.searchCompanies({ keywords: jobCompanyName });
  const [{ company: jobCompany }] = await companiesScroller.scrollNext();

  // Search for profiles and send an invitation
  const peopleScroller = await client.search.searchPeople({
    keywords: 'Bill Gates'
  });
  const [{ profile: billGates }] = await peopleScroller.scrollNext();
  
  await client.invitation.sendInvitation({
    profileId: billGates.profileId,
    trackingId: billGates.trackingId,
  });
  
  // Search in my connections
  const ownConnectionsScroller = await client.search.searchOwnConnections({ keywords: 'Bill Gates', limit: 1 });
  const connections = await ownConnectionsScroller.scrollNext();

  // Get conversation
  const [billConversation] = await client.conversation.getConversations({
    recipients: billGates.profileId
  }).scrollNext();
 
  const conversationMessages = await client.message.getMessages({
    conversationId: billConversation.conversationId
  }).scrollNext()
 
  // Send a message
  const sentMessage = await client.message.sendMessage({
    profileId: billGates.profileId,
    text: 'Hey Bill!',
  });
})();

API

Repositories

Classes that expose methods for communicating with linkedin API.
Each repository describes a LinkedIn entity that we can operate on it. Example: InvitationRepository.

The methods are divided into 3 types:

• Single entity getters - example: conversation.getConversation({ conversationId: CONVERSATION_ID }) Single entity getters return a LinkedIn Entity.

• Multiple entities getters - for example invitation.getSentInvitations({ skip: 10, limit: 5 })
  Multiple entities getters return a Scroller.

• Mutations - for example invitation.sendInvitation({ ... })
  Mutations return a Response entity

|Name|Example Usage|Docs Reference| |-|-|-| |login|client.login.userPass(...)|Login Docs| |search|client.search.searchPeople()|Search Docs| |profile|client.profile.getOwnProfile()|Profile Docs| |invitation|client.invitation.getReceivedInvitations()|Invitation Docs| |conversation|client.conversation.getConversation(...)|Conversation Docs| |message|client.message.getMessages(...)|Message Docs|

Entities

Interfaces that describe LinkedIn objects. For example - Conversation object.
Most of those entities contain the properties returned from the LinkedIn response and in addition to these properties, the API adds some extra properties to make the usage a bit easier.

The full list of entities can be found here, this is the list of the most important ones:

|Entities| |-| |Profile| |MiniProfile| |MiniCompany| |Invitation| |Conversation| |Message| |CompanySearchHit| |PeopleSearchHit| |JobSearchHit| |MessageCreateResponse|

Scrollers

Wrapper classes that enable a convenient work with paginated responses. For example - PeopleScroller.
Most of LinkedIn requests return paginated responses, (just like in the UI), scrollers just provide a structured way to navigate between pages.

There are two types of scrollers:

• Index scroller - Accepts 2 properties:
  skip (number) - Starting index (How many entities to skip).
  limit (number) - How many entities to fetch on each iteration.

• Time scrollers - Accepts one property:
  createdBefore (Date) - Defines the point of time to start fetching entities.

Example:

// index scroller
let companiesScroller = client.search.searchCompanies(); 
let companies = await companiesScroller.scrollNext(); // returns first page with 10 results
companies = await companiesScroller.scrollNext(); // next page
companies = await companiesScroller.scrollBack(); // previous page

// overriding skip and limit
companiesScroller = client.search.searchCompanies({ skip: 100, limit: 1 }); 
companies = await companiesScroller.scrollNext(); // returns first page with 1 results
companies = await companiesScroller.scrollNext(); // next page
companies = await companiesScroller.scrollBack(); // previous page

// overriding createdBefore for time scroller
const twoDaysAgo = moment().subtract(2, 'days').toDate();
let messagesScroller = client.message.getMessages({
  conversationId: CONVERSATION_ID,
  createdBefore: twoDaysAgo
});
messages = await companiesScroller.scrollNext();

What's coming next?

A lot!

This is a new project, and as such, there's a lot that need to be done.
Some new features that I expect to develop soon:

• Media support - fetch, like, comment and create a new post.
• Invitation improvements - be able to do some more actions like "remove connection".
• Improve login API
• Add services so automate common workflows

Want a specific feature? Please open a feature request :)
Also, i'll be more than happy to welcome new contributors to this project.
