On Express

If you already have an application running using Express ↗, the easiest way to attach the Forest Admin agent would use the mountOnExpress function, just like in the following example:

require('dotenv').config();

const { createAgent } = require('@forestadmin/agent');
const { createSqlDataSource } = require('@forestadmin/datasource-sql');
const express = require('express');

const agent = createAgent({
  authSecret: process.env.FOREST_AUTH_SECRET,
  envSecret: process.env.FOREST_ENV_SECRET,
  isProduction: process.env.NODE_ENV === 'production',
});

const app = express();

// This function must be called before other middlewares.
agent.mountOnExpress(app).start();

app.listen(3000);
