Setting up Backend for Lancer Integration

Info: This documentent primarily focuses on library authors. If you want to integrate Lancer into your application please checkout SDK & Packages page

In this section we'll use express js to setup a basic server and endpoints required for lancer to get start with file upload.

Prerequisites​

Before proceeding, ensure you have the following installed:

  • Node.js : Version 14 or above.
  • Express : For building the server.
  • jsonwebtoken (JWT) : For handling token-based authentication.

Install Required Dependencies​

Install the necessary packages using npm:

npm install express jsonwebtoken

Overview​

Remeber we have two endpoint defined in our config file , so we have to add two endpoints as well into our server.

  • Authentication Endpoint : /auth Authenticates incoming requests from Lancer clients.
  • Webhook Events Endpoint : /webhook Handles the events sent from the Lancer .

Setup the server​

Create a new file server.js and set up the basic Express server:

import express from "express";

const app = express();
const PORT = 3000;

app.use(express.json());

app.listen(PORT, () => {
  console.log(`Server running on http://localhost:${PORT}`);
});
