Firecrawl Local Dev Loop
Overview
Set up a fast development workflow for Firecrawl integrations. Use self-hosted Firecrawl via Docker to avoid burning API credits during development, mock the SDK for unit tests, and run integration tests against the local instance.
Prerequisites
Node.js 18+ with npm/pnpm
Docker + Docker Compose (for self-hosted Firecrawl)
@mendable/firecrawl-js installed
Instructions
Step 1: Project Structure
my-firecrawl-project/
├── src/
│ ├── scraper.ts # Firecrawl business logic
│ └── config.ts # Environment-aware config
├── tests/
│ ├── scraper.test.ts # Unit tests (mocked SDK)
│ └── integration.test.ts # Integration tests (real API)
├── docker-compose.yml # Self-hosted Firecrawl
├── .env.local # Dev secrets (git-ignored)
├── .env.example # Template for team
└── package.json
Step 2: Self-Hosted Firecrawl for Zero-Credit Dev
services:
firecrawl:
image: mendableai/firecrawl:latest
ports:
- "3002:3002"
environment:
- PORT=3002
- USE_DB_AUTHENTICATION=false
- REDIS_URL=redis://redis:6379
- NUM_WORKERS_PER_QUEUE=1
- BULL_AUTH_KEY=devonly

set -euo pipefail
docker compose up -d
curl -s http://localhost:3002/health | jq .
Step 3: Environment-Aware Configuration
import FirecrawlApp from "@mendable/firecrawl-js" ;
export function getFirecrawl (FirecrawlApp {
const isDev = process.env .NODE_ENV !== "production" ;
return new FirecrawlApp ({
apiKey : process.env .FIRECRAWL_API_KEY || "fc-dev" ,
...(isDev && process.env .FIRECRAWL_API_URL
? { apiUrl : process.env .FIRECRAWL_API_URL }
: {}),
});
}
FIRECRAWL_API_KEY=fc-localdev
FIRECRAWL_API_URL=http://localhost:3002
NODE_ENV=development
Step 4: Unit Tests with Mocked SDK
import { describe, it, expect, vi, beforeEach } from "vitest" ;
vi.mock ("@mendable/firecrawl-js" , () => ({
default : vi.fn ().mockImplementation (() => ({
scrapeUrl : vi.fn ().mockResolvedValue ({
success : true ,
markdown : "# Hello World\n\nSample content from mock" ,
metadata : { title : "Hello World" , sourceURL : "https://example.com" },
}),
crawlUrl : vi.fn ().mockResolvedValue ({
success : true ,
data : [
{
markdown : "# Page 1" ,
metadata : { sourceURL : "https://example.com/page1" },
},
],
}),
mapUrl : vi.fn ().mockResolvedValue ({
success : true ,
links : ["https://example.com/a" , "https://example.com/b" ],
}),
})),
}));
import { scrapeAndProcess } from "../src/scraper" ;
describe ("Scraper" , () => {
it ("returns cleaned markdown" , async () => {
const result = await scrapeAndProcess ("https://example.com" );
expect (result.markdown ).toContain ("Hello World" );
expect (result.metadata .title ).toBe ("Hello World" );
});
});
Step 5: Integration Tests Against Local Instance
import { describe, it, expect } from "vitest" ;
import FirecrawlApp from "@mendable/firecrawl-js" ;
const FIRECRAWL_URL = process.env .FIRECRAWL_API_URL || "http://localhost:3002" ;
describe.skipIf (!process.env .FIRECRAWL_API_URL )("Firecrawl Integration" , () => {
const firecrawl = new FirecrawlApp ({
apiKey : "fc-test" ,
apiUrl : FIRECRAWL_URL ,
});
it ("scrapes a page to markdown" , async () => {
const result = await firecrawl.scrapeUrl ("https://example.com" , {
formats : ["markdown" ],
});
expect (result.success ).toBe (true );
expect (result.markdown ).toBeDefined ();
expect (result.markdown !.length ).toBeGreaterThan (50 );
}, 30000 );
});
Step 6: Dev Scripts {
"scripts" : {
"dev" : "tsx watch src/index.ts" ,
"test" : "vitest" ,
"test:watch" : "vitest --watch" ,
"test:integration" : "FIRECRAWL_API_URL=http://localhost:3002 vitest run tests/integration" ,
"firecrawl:up" : "docker compose up -d" ,
"firecrawl:down" : "docker compose down" ,
"firecrawl:logs" : "docker compose logs -f firecrawl"
}
}
Output
Self-hosted Firecrawl running on localhost:3002
Unit tests with mocked SDK (zero API calls)
Integration tests against local instance
Hot-reload dev server with tsx watch
