We previously used the GCP Pyhton library to get a list of Google Cloud Storage subdirectories, and this is the Node.js version of that.
Python version is here
procedure
The GCP Node.js SDK documentation is kind enough to provide a sample.
Use bucket.getFiles() with "autoPaginate" set to "false", "delimiter" set to "/", and "prefix" set to "parent directory+/".
Then, a list of subdirectories will be entered into the "prefixes" array of the returned "apiResponse".
If Promise is used, "apiResponse" is the third value in the return array.
The code based on the above is shown below.
import { Storage } from '@google-colud/storage'; const storage = new Storage(); const bucket = storage.bucket('xxxx'); async (()=>{ const files = await bucket.getFiles({ autoPaginate: false, delimiter: '/', prefix: 'a/' }); files[2].prefixes.forEach((dir:any)=>{ console.log(dir); } // xxxx/a/01/ // xxxx/a/02/ })();
Impressions, etc.
See the Python article for a hook-up point about directories in cloud storage.
Both Python and JavaScript end up calling the same API, but the way the libraries are written differs depending on the language.
I would like to see it standardized, but I guess the fact that it is closed in the language allows for speedy updates.
For the first time, I used Promise of GCP Node.js SDK. The return value is an array of arguments after "err" in the callback.
It would have been cooler if the return value was an object instead of an array...
