title: Export your Farcaster posts

I recently decided to quit Farcaster for several reasons. You can read about them
in the `elon-mind-virus.txt` post. Anyhoo, here's the Deno script I made,
adapted from Neynar's Node.js archiver script[1]:

```ts



//// import

import { appendFile } from "node:fs";
import { NeynarAPIClient } from "npm:@neynar/nodejs-sdk";

//// var

const client = new NeynarAPIClient("YOUR_NEYNAR_API_KEY");
const fid = 16152; /// your Farcaster FID

const dumpCast = (cast) => {
  const data = `${JSON.stringify(cast)}\n`;

  appendFile(`${fid}_export.ndjson`, data, (err) => {
    if (err)
      throw err;

    console.log(`${cast.hash} processed`);
  });
};

const fetchAndDump = async(fid, cursor) => {
  const data = await client.fetchAllCastsCreatedByUser(fid, {
    cursor,
    limit: 150
  });

  data.result.casts.map(dumpCast);

  if (data.result.next.cursor === null)
    return; /// if no cursor, fin

  await fetchAndDump(fid, data.result.next.cursor);
};



//// program

fetchAndDump(fid);



//// deno run --allow-env --allow-net --allow-write export_farcaster.ts
```

This will only export your public posts, not your DMs. If you don't want to pay
Neynar[2], you can use these[3] projects[4].
