Firecrawl Data Handling
Overview
Process scraped web content from Firecrawl pipelines. Covers markdown cleaning, structured data extraction with Zod validation, content deduplication, chunking for LLM/RAG, and storage patterns for crawled content.
Instructions
Step 1: Content Cleaning
import FirecrawlApp from "@mendable/firecrawl-js" ;
const firecrawl = new FirecrawlApp ({
apiKey : process.env .FIRECRAWL_API_KEY !,
});
async function scrapeClean (url : string const result = await firecrawl.scrapeUrl (url, {
formats : ["markdown" ],
onlyMainContent : true ,
excludeTags : ["script" , "style" , "nav" , "footer" , "iframe" ],
waitFor : 2000 ,
});
return {
url : result.metadata ?.sourceURL || url,
title : result.metadata ?.title || "" ,
markdown : cleanMarkdown (result.markdown || "" ),
scrapedAt : new
Date
toISOString
function
cleanMarkdown
md : string
string
return
replace
/\n{3,}/g
"\n\n"
replace
/\[.*?\]\(javascript:.*?\)/g
""
replace
/!\[.*?\]\(data:.*?\)/g
""
replace
/<!--[\s\S]*?-->/g
""
replace
/<script[\s\S]*?<\/script>/gi
""
trim
Step 2: Structured Extraction with Validation import { z } from "zod" ;
const ArticleSchema = z.object ({
title : z.string ().min (1 ),
author : z.string ().optional (),
publishedDate : z.string ().optional (),
content : z.string ().min (50 ),
wordCount : z.number (),
});
async function extractArticle (url : string const result = await firecrawl.scrapeUrl (url, {
formats : ["extract" ],
extract : {
schema : {
type : "object" ,
properties : {
title : { type : "string" },
author : { type : "string" },
publishedDate : { type : "string" },
content : { type : "string" },
},
required : ["title" , "content" ],
},
},
});
if (!result.extract ) throw new Error (`Extraction failed for ${url} ` );
return ArticleSchema .parse ({
...result.extract ,
wordCount : (result.extract .content || "" ).split (/\s+/ ).length ,
});
}
Step 3: Content Deduplication import { createHash } from "crypto" ;
function contentHash (text : string string {
return createHash ("sha256" )
.update (text.trim ().toLowerCase ())
.digest ("hex" );
}
function deduplicatePages (pages : Array <{ url: string ; markdown: string }>const seen = new Map <string , string >();
const unique : typeof pages = [];
const duplicates : Array <{ url : string ; duplicateOf : string }> = [];
for (const page of pages) {
const hash = contentHash (page.markdown );
if (seen.has (hash)) {
duplicates.push ({ url : page.url , duplicateOf : seen.get (hash)! });
} else {
seen.set (hash, page.url );
unique.push (page);
}
}
console .log (`Dedup: ${pages.length} input, ${unique.length} unique, ${duplicates.length} duplicates` );
return { unique, duplicates };
}
Step 4: Chunk for LLM / RAG interface ContentChunk {
url : string ;
title : string ;
chunkIndex : number ;
content : string ;
wordCount : number ;
}
function chunkForRAG (
url : string ,
title : string ,
markdown : string ,
maxWords = 800
): ContentChunk [] {
const sections = markdown.split (/\n(?=#{1,3}\s)/ );
const chunks : ContentChunk [] = [];
let current = "" ;
let index = 0 ;
for (const section of sections) {
const combined = current ? `${current} \n\n${section} ` : section;
if (combined.split (/\s+/ ).length > maxWords && current) {
chunks.push ({
url, title, chunkIndex : index++,
content : current.trim (),
wordCount : current.split (/\s+/ ).length ,
});
current = section;
} else {
current = combined;
}
}
if (current.trim ()) {
chunks.push ({
url, title, chunkIndex : index,
content : current.trim (),
wordCount : current.split (/\s+/ ).length ,
});
}
return chunks;
}
Step 5: Crawl and Store Pipeline import { writeFileSync, mkdirSync } from "fs" ;
import { join } from "path" ;
async function crawlAndStore (baseUrl : string , outputDir : string , opts ?: {
maxPages?: number ;
paths?: string [];
}mkdirSync (outputDir, { recursive : true });
const crawlResult = await firecrawl.crawlUrl (baseUrl, {
limit : opts?.maxPages || 50 ,
includePaths : opts?.paths ,
scrapeOptions : { formats : ["markdown" ], onlyMainContent : true },
});
const pages = (crawlResult.data || []).map (page =>url : page.metadata ?.sourceURL || baseUrl,
markdown : cleanMarkdown (page.markdown || "" ),
}));
const { unique } = deduplicatePages (pages);
const manifest = unique.map (page =>const slug = new URL (page.url ).pathname
.replace (/\//g , "_" ).replace (/^_|_$/g , "" ) || "index" ;
const filename = `${slug} .md` ;
writeFileSync (join (outputDir, filename), page.markdown );
return { url : page.url , file : filename, size : page.markdown .length };
});
writeFileSync (join (outputDir, "manifest.json" ), JSON .stringify (manifest, null , 2 ));
return manifest;
}
Error Handling Issue Cause Solution Empty content JS not rendered Increase waitFor, use onlyMainContent Garbage in markdown Bad HTML cleanup Add excludeTags for problematic elements Duplicate pages URL aliases or redirects Content-hash deduplication Oversized chunks Long single sections Add word limit to chunking logic Extract returns null Page too complex for LLM Simplify schema, use shorter prompt
Examples
Documentation Scraper with RAG Output const docs = await crawlAndStore ("https://docs.example.com" , "./scraped-docs" , {
maxPages : 50 ,
paths : ["/docs/*" , "/api/*" ],
});
for (const doc of docs) {
const content = readFileSync (`./scraped-docs/${doc.file} ` , "utf-8" );
const chunks = chunkForRAG (doc.url , doc.file , content);
console .log (`${doc.url} : ${chunks.length} chunks` );
}
