On Fastify

This is the official documentation of the @forestadmin/agent Node.js agent.

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

require('dotenv').config();

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

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

const app = fastify();

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

app.listen(3000);

Using Fastify v4.x

You should use @fastify/middie library to be able to use Fastify v4.x with Forest Admin.

This library adds middleware support to Fastify.

const fastifyAppV4 = Fastify();
await fastifyAppV4.register(import('@fastify/middie'));
agent.mountOnFastify(fastifyAppV4);
