Upload Files

With the help of the file upload component, you can now gather the data that you want to upload as Fle to your Bucket. There are two possible file types in general.

• Text based Files like JSON or CSV

• Binary Files

From the possible actions of the S3 Datasource Plugin you can choose "Upload file" and fill in the settings.

Choose "List Buckets" to get a JSON List of your S3 Buckets.

// Response of "List buckets"

  {
    "name": "lowcoder-documentation-bucket"
  }
]

With the name of the Bucket you can now request a list of all Files.

// Response of "List files"

  {
    "name": "open_issues.json",
    "size": 247285,

    "signedUrl": "",

An alternative way to access the File is via the secure Link (Signed URL). To get the "signed Link URLs" for your files, just use the "List files" method including the "Return signed url" checkbox.

You can now use the URL of each file and for example, display it in the File viewer or with the Image Component.

You can use the Method "Delete file" to ... delete a single file from your Bucket.
