Quick Start (5 Minutes)

1. Create Your Flag

Log in to the FlagPilot dashboard, click Create Feature Flag, set the key to my-first-flag, and set the default state to enabled in development.

2. Install SDK & Config Credentials

Install the Node.js SDK:

npm install @flagpilot/node

Add your environment variable to a .env file:

FLAGPILOT_SECRET_KEY=fk_secret_xxxx

3. Evaluate the Flag in Code

Write code to evaluate your flag status:

import { FlagPilot } from '@flagpilot/node';

const flagpilot = new FlagPilot({
  apiKey: process.env.FLAGPILOT_SECRET_KEY,
  environment: 'production'
});

await flagpilot.initialize();

const enabled = await flagpilot.evaluate('my-first-flag', { userId: 'user_123' });
if (enabled) {
  console.log("Flag is enabled!");
}

4. Verify Evaluated Metric Logs

Run your code. Then return to the dashboard, select the flag, and check that active evaluation counters immediately increment inside the flag's details panel.
