Is that possible? Get md5 of a video file using bubble?

Create a plugin, add a server side action

Add a field called file

Add a New key called files_md5

const fetch = require('cross-fetch');
const crypto = require('crypto');

let result = context.async(async callback  => { 
  let res = await fetch('https:' + properties.file);
  let fileBytes = await res.arrayBuffer();
  const hash = crypto.createHash('md5');
  hash.update(Buffer.from(fileBytes));
  const md5Hash = hash.digest('hex');
  callback(null, md5Hash);
});

return {
files_md5: result
}

You probably know it already: the last version published of cross-fetchis from 1 year ago and it depends on node-fetch v2.
node-fetch is already at v3.3 so you might want to use an updated library instead.

edit: I missed this info from the node-fetch documentation:

If you cannot switch to ESM, please use v2 which remains compatible with CommonJS. Critical bug fixes will continue to be published for v2.

Of course node-fetch v3 is not compatible with bubble’s server actions and you should be fine with node-fetch v2 and cross-fetch as long as they keep publish critical bug fixes.

I meant to ask you but got caught up. How did you get node-fetch to work?

My mistake. I don’t use node-fetch at all on bubble, and that’s why I missed a piece of info about v2.
I just updated my answer to reflect that your example, as of today, is totally ok.
I hope one day we will be able to use ESM in bubble plugins.

I think that’s coming. At least that’s how I took the last update.

I think the last update is more about this, hence the need to switch to async. :man_shrugging:

there is always this:

const [body, status] = context.async(async (cb) => {
  try {
    const { default: fetch } = await import("node-fetch");
    const response = await fetch("https://github.com/");
    const body = await response.text();
    cb(null, [body, response.status]);
  } catch (e) {
    cb(e);
  }
});

return { body, status };

with this package.json:

{
  "dependencies": {
    "node-fetch": "3.3.0"
  }
}
