How do I delete files from AWS S3 using the S3Adapter with CloudCode

jayson · May 24, 2022, 10:25am

I’m looking to delete files off of my S3 bucket on afterDelete('MyImageClass") in CloudCode.

I am using the S3Adapter on my ParseServer setup and can save files as expected to my S3 Bucket.

But, how do I go about accessing or deleting the files off of my S3 bucket when in CloudCode? Can anyone point me to the docs (which for the life of me I couldn’t find). or any leads so I could try it out?

I found this deleteFile function in the index.js file but how do I go about accessing this in CloudCode if it’s possible to?

github.com

parse-community/parse-server-s3-adapter/blob/5cb9c675794b071e57d26bab81cbb060afe0cd1b/index.js#L124

    
      
            return this.createBucket().then(() => new Promise((resolve, reject) => {
              this._s3Client.upload(params, (err, response) => {
                if (err !== null) {
                  return reject(err);
                }
                return resolve(response);
              });
            }));
          }
          
          
deleteFile(filename) {
            return this.createBucket().then(() => new Promise((resolve, reject) => {
              const params = {
                Key: this._bucketPrefix + filename,
              };
              this._s3Client.deleteObject(params, (err, data) => {
                if (err !== null) {
                  return reject(err);
                }
                return resolve(data);
              });

thanks!
